Crimes Scenes And Evidence Gathering Underpin Every Police...
Crimes scenes and evidence gathering underpin every police investigation. From the moment police
arrive to a scene to the moment a verdict is decided upon the offender, the way in which crime
scenes are established and evidence gathered holds significant weight on the outcome. By discussing
the provided scenario along with the issues surrounding the establishment of crime scenes, the way
in which evidence is gathered, legislative and policy powers and requirements, and the phenomena
of Locard's Principle, we can establish an understanding of best practice which ultimately will
positively impact the final outcome of a verdict.
General identifying statement
Ensuring a crime scene is established in the wake of an incident lays the foundation for an effective
investigation. Horswell, J. (2004) describes a crime scene as simply a place which is connected to a
crime or incident, either primary or secondary in nature. A primary crime scene being that of where
the crime occurred and where the majority of evidence can be found, while secondary being that of
where evidence relating to the crime may exist elsewhere (p. 32). In relation to the provided
scenario, the house in case is the primary crime scene; as this is where the incident has occurred and
where the majority of evidence will be located. A secondary crime scene is not present in the scope
of the provided scenario, hypothetically however, if stolen property of the victim was to be found

Death Investigation : A Guide For The Scene Investigator
Death investigation has been performed for a considerable length of time in all social orders, albeit not generally by medical experts .The relationship
of law and medicine goes back to the Egyptian society as early as 3000 B.C. The English coroner framework was said in documentations around the
twelfth century B.C. Despite the fact that the essential objective of a death investigation is to build up the cause and manner of death, the death
investigation part expands much more remote. While without a doubt the dead can 't take advantage, the quality in death investigation is to benefit the
living and future eras. In a culture that values life, clarifying the demise in an open gathering is essential for many reasons ("Journal of the American
Academy of Psychiatry and the Law Online"). In June 2011, the United States Department of Justice released a revised and updated edition of the 1999
version of the manual, titled Death Investigation: A Guide for the Scene Investigator. This manual discusses proper guidelines for conducting death
investigations in all stages of the investigation, what investigative tools and equipment are needed, and step by step instructions from when arriving at
the crime scene to departing. The manual gives a decent synopsis on how investigations including death ought to be drawn closer, yet does not expand
much on potential issues that would be tended to, why certain methods are so imperative, and is ambiguous in a few zones ("A Guide to Death Scene

DNA In Crime Scene Investigation
Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a
suspect's guilt or innocence (Butler, 2005). The method of constructing a distinctive "fingerprint" from an individual's DNA was first described by
Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as
variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005).
Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of
DNA ... Show more content on Helpwriting.net ...
Each person inherits two copies of these markers from his or her mother and father, so a higher similarity denotes a closer biological relationship.
The probability of two samples matching is around one in a billion (dna.gov). DNA profiles are compiled by using gel or capillary electrophoresis
to separate samples into a pattern distinctive of the subject's DNA based on ionic charge, size, or mobility. Usually, samples in the database are
searched at moderate stringency, which requires that all alleles between the two samples match, but the number of alleles can vary, accounting for
DNA contamination or degradation. Partial, or candidate, matches are samples that have a similar number of alleles in the forensic profile but are not
exact, and are used in familial DNA searching to find close biological relatives of the original forensic profile. Other evidence is used to determine
relatives, including Y chromosome analysis, which traces family relationships based on the fact that the Y chromosome is transmitted directly between
a father and his sons; age; and geographic location. The process is based on the principle that first–order relatives have closer DNA profiles than
unrelated individuals, and also on the sociological assumption that criminal tendencies appear in families; according to "the Bureau of Justice Statistics

Crime Scene Investigation Essay
At a crime scene, insects can provide important pieces of information to criminal investigators, including estimating the post–mortem interval (PMI)
and determining where the crime took place. This is only possible, however, if the local insect fauna is known, thereby facilitating the need for local
insect population surveys at both the morphological and gene levels. Although flies (order Diptera) are one of the first and most prevalent
necrophagic insect species found associated with a corpse, beetles (order Coleoptera) are also a forensically relevant insect that can play a significant
role in crime scene investigations.
In this study, the objective was to survey the Coleoptera population in Lyon County, Kansas during the early spring. Insects were collected using
light traps during the evening hours and DNA was isolated from each collected specimen followed by amplification of the cytochrome oxidase I (COI)
gene. The cytochrome oxidase I (COI) gene is known to be as a standard barcode gene. (CBOL, 2010) This barcode gene is a 648 base pair mostly

Police Scene Investigation And Reconstruction
General Identifying Statement
Crime scene investigation and reconstruction are both central aspects in the study of policing. By definition, a crime scene is a scene or place where
an offence has been committed, and the site where forensic evidence is to be gathered in the pursuit of investigating the offence (Fisher, 2012, p.10).
Fisher goes on to clarify that a crime scene may refer to a physical place that may provide potential evidence to an investigator. This is not limited to
a location but rather may include a include a person's body, any type of building, vehicles, places in the open air or objects found at those locations.
Fisher elaborates; explaining how hoth forensic and scientific techniques are used in order to preserve and obtain evidence of crime at the crime scene.
(Fisher, 2012, p. 13).
Lee and Palmbach (2001) point out that the processes involved in examining a crime scene does not need to be sophisticated or elaborate; instead,
investigators need to concern themselves with adhering to the fundamental principles and procedures within crime scene investigation. It is important
to remember that there is not a comprehensive plan or sole guiding principle when it comes to processing crime scenes (Pepper, 2010, p. 101). This
being the case, exploring different protocols and methods that assist in forming a logical plan towards crime scene investigation is crucial in policing.

Homicide detectives only investigate and focus on Homicides. College educations are recommended but not required. Murder detectives collect
evidence like fingerprints DNA and stuff like that. They interview suspects and witnesses who may have information for the murder. There are
two types of crime scenes. The primary crime scene is where the crime scene is where the crime actually occurred. for example if a bank get robs
that is the primary scene and the getaway car and the lair are the secondary scene. primary crime scenes are usually more helpful. while secondary
scenes sometimes are the only thing that criminologists have to work with. For example this may be where a serial killer dumps a body. So
investigators may not be able to prove where the actual murder occurred. which means they only find evidence at the secondary scene which could
lead to the primary scene or prove that is where the crime happened. For example you may find a hair or a fiber at a scene that could lead to a specific

around the skull were three layers of duct tape. Dr. Garavaglia was able to note that this was done prior to any decomposition of the body. This was
because the mandible remained attached to the skull after decomposition had occurred completely. (Casey Anthony Trial, 2011) Usually, once thesoft
tissue breaks away, there is nothing holding the lower jaw to the upper skull portion. The tape had held the mandible in place and all of the baby
teeth were still in place. This is fairly unusual because baby teeth are temporary and do not have true roots holding them in once the tissue is gone.
(Casey Anthony Case, 2013) The tape had been wound through the child's hair and was still clinging into the tape. Over the mouth area, there was a
heart shaped sticker. Investigators found similar stickers in Casey's room. This pointed even more to the remains belonging to Caylee Anthony.

The Influence Of CSI: Crime Scene Investigation
The CSI effect is the phenomenon in which jurors hold unrealistic expectations of forensic evidence and investigation techniques, and have an
increased interest in the discipline of forensic science because of the influence of CSI–type television shows. This effect includes raising the state's
burden of proof because of jury expectations that forensic evidence should always be discussed at trial, and the belief that forensic evidence is never
wrong. The show CSI: Crime Scene Investigation provides inaccurate information by closely relating to the reality of the investigation, but
accelerating and exaggerating long processes in the criminal justice system. For example, searching databases for fingerprints and other DNA
evidence can take months, whereas in the show it takes only minutes or hours. Also, an increase in demand for forensic evidence for a conviction has
placed a higher burden of proof on the prosecutors. Whereas, forensic evidence is not always available or necessary for a ... Show more content on

The stories were not just about cases where all procedures were correctly followed, but also included stories about rookie mistakes. I really enjoyed the
about unique cases–such as the man killed by the falling icicle (Genge 79). In another story, young woman was found hanged, and police were charged
with the task of determining if she had committed suicide or if she was the victim of a homicide. After much investigation, the cause of death was listed
as an accident. Evidently the young woman's friend stated that she had helped tie the knot on the rope–never believing that the young woman would
actually kill herself (Genge 92). After the ruling, the police were not entirely convinced that it was an accidental death even though no sign of struggle
was evident; however, there was insufficient evidence to prove otherwise (Genge 92). The discipline I enjoyed reading the most about was the use of
animal examiners–dogs. The author was very thorough with the subject, even going so far as to explain why dogs are normally used instead of
other animals such as pigs, cats, and ferrets. According to Genge, dogs enjoy working because of the praise earned, whereas pigs are easily
sidetracked by the smell of food, cats "don't like to work," and the attention span of a ferret is almost non–existent (Genge 210). Another interesting
fact about dogs is that the canine nose is adept at sniffing out old

They have to make sure that before they entered the crime scene, nothing in the scene should have been moved. While they are going through a
walk–through, they may have to construct theories about what happened in the crime scene based on visual examination. Investigators have to take
photographs of the scene and will later on be collected. Taking photographs of the scene will help them solve the crime because there are some
points of the investigation that investigators may have overlooked evidence, and that evidence could be found in the photographs. After taking
photographs of the scene, they will start to collect clue and evidence that may lead them to their possible suspect(s). What they may find in the crime
scene are fingerprints which can be done using colored powder and a brush, other thizngs such as blood, firearms, hair, glass and many more things
that can be found in the crime scenes. After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime

within the crime scene, but it's not as simple as just finding a computer and taking it to the lab. "Digital evidence is information stored or transmitted
in binary form that may be relied on in court. It can be found on a computer hard drive, a mobile phone, a personal digital assistant (PDA), a CD, and a

There are three kinds of sciences to look at: Pure, Applied, and Junk. Pure science defined as; systematic observation of natural phenomena solely for
the discovery of unknown laws relating to facts; the study of science alone, not including its relations to other subjects (dicionary.com, 2018). This
science looks at facts that one derives from mathematics and logic; the natural science. The second is Applied science. Applied science is: the
discipline dealing with the art or science of applying scientific knowledge to practical problems; "he had trouble deciding which branch of engineering
to study" (Farlex, 2018). This science deals with facts from machines, inventions, and technology. The third is junk science. Junk science is: faulty
scientific information or research, especially when used to advance special interests (dictionary.com, 2018). Once a person decides to use the sciences
to figure out fact or fiction one uses the scientific method to find the facts. The steps one follows for this process include: Observation, hypothesis,

Luminol And Crime Scene Investigation
Blood is one of the most important evidence that can be found at the crime scene since violence always happens in the criminal event. The search of
blood is mostly done by close observation of investigators, however, sometimes blood in the crime scene will be wiped out by the murderer, or,
sometimes the amount of blood will be too little to be observed without the assistance of other substance. For this kind of situation, luminol can be used
in order to help criminalists to detect blood in the crime scene.
Luminol (5–Amino–2,3–dihydro–1,4–phthalazinedione) is a compound that made up with carbon, hydrogen, oxygen and nitrogen, the chemical
formula of luminol is C8H7O3N3, it is in a form of powder at room temperature and room pressure. The chemical reaction of luminol and the reactant
is a chemiluminescence reaction, which emits strong blue light during the reaction. Luminol can't be used alone, in order to use it, criminalists must
first activate it first. Luminol needs to mix with a strong oxidizing agent such as hydrogen peroxide (H2O2). Other than a strong oxidizing solution, a
basic solution is also needed, for the basic solution, alkali like sodium hydroxide can be used. Addition of basic solution and strong oxidizing agent

However, the reaction is not just specific to blood, some other substances can also catalyse the oxidation of luminol such as bleach, certain metals, or

suicide – one male, one female. For both spaces I chose the quadrant method for searching – not a large space – but due to evidence and appearance of
movement, I believe the quadrant search will be easier to catalog and document evidence, conduct measurements (solid reference points), and
capture photographic images. My evidence spans two locations. The first is the kitchen dining area. There is no sign of a struggle; there is a
round table with four chairs and miscellaneous table items (napkins, flower vase etc.). On the table, there is a cell phone, two chairs pulled away
from the table, one glass with what appears to be wine in it. Next to the table is a small suit case which appears to be pack with clothes. The wine glass

The National Forensics Academy was full of multiple dimensions of crime scene investigation that I had not even thought about nor learned about in
the past. The world of crime scene investigation is interesting to me because of all these aspects and because they are ever changing, and new and
better methods are being discovered. Throughout the academy I learned about these aspects in detail and how there are various methods within each
aspect. The aspects that I learned were how to photograph a crime scene, finger printing, foot impressions, crime scene sketches, blood spatter analysis,
bullet holes, bones, and digging up a grace to recover a body. These aspects work together to investigate and recreate crime scenes.
A part of crime scene investigation that I had never put much thought into was the photography. Taking photos of everything at a scene and the
methods of how to photograph scenes are important in working a scene. I had never had the opportunity to work with the type of cameras that we used
at the academy and I was unaware of the work that goes into photographing a picture. Before taking a photo one must adjust the settings including the
F–stop, ISO, and shutter speed of the camera. In order to take a picture of a moving object you must adjust the shutter speed so it can capture the

that the people who work as investigators are not particularly pretty people with pencil skirts, expensive suits, and a full hair and makeup team; they
are law enforcers that specialize in the science aspect of solving crimes.

were recruited from civilian life and it wasn't until the 1950s that a college education was preferred in the investigations department (O'Connor, 2006,
para. 3). The first major private detective agency of the nineteenth–century was formed by Allan Pinkerton in 1819–1884 (Swanson et al., 2002, para 1).
In my opinion, the biggest milestone for investigative work was the discovery of DNA. It has made the task of apprehending criminals exponentially
easier and is virtually error–free.
How to become a Criminal Investigator There are different ways to become a criminal investigator: you can go to school and major in criminology or
criminal science and get hired as a criminal investigator–perhaps in a small town where prior experience is not required–or you can take the most
common avenue and become a police officer first. After becoming a sworn police officer, you can receive on–the–job training and attend specialized
classes to become an investigator. Speaking with a current Myrtle Beach Police Crime Scene Investigator, David Bailey, I learned that if you want to

Crime Scene Investigation
Since the time that the scientific science dramatization "CSI: Crime Scene Investigation" turned into a tremendous hit and generated its fans, reporters
have been worried about what they instituted the "CSI Effect." The hypothesis behind the effect is that fans of the well–known show disguise
misguided judgments about the law that they bring with them into the court as jurors. In this way, the trepidation is that the TV show is at last
influencing the results of trials – and not in a great manner. Criminal justice researchers have started to study the inquiry of whether nationals who are
called to serve on juries bring unreasonable desires and convictions to the court as a consequence of TV projects. The impact that these projects may
have on the jurors, their desires, and their choices is known as the CSI effect. Less frequently, individuals will allude to the "CSI Effect" to allude to the
inverse, nonetheless. Defense attorneys, for instance, now and again contend that attendants impacted by "CSI" have a tendency to accept that any
scientific confirmation gathered will be implicating. This is likewise hazardous, commentators say, in light of the fact that individuals don't normally
think about the likelihood of error or even fraud [source: Cole. Scientific researchers have been known to fudge results about request to get a

There are vital stages of crime scene investigation that will be portrayed and analyzed through scholarly sources. A crime scene investigation must start
with a crime committed, whether it be a burglary or a homicide. The first responders (police officers, fire fighters, emergency medical personnel, etc.)

Protection of the crime scene starts when the first responding officer arrives at the scene. Often times, the police officer's "swoop and scoop" idea
prohibits all of the evidence and identification to be discovered. "Swoop and scoop" is the process that many police officers take at crime scenes;
they will approach the scene and very quickly "find evidence" so that they can proceed to the next call. Police officers, firefighters, and emergency
medical workers are the first to arrive on scene to assess any health concerns and make sure there are no "perpetrators" in the surrounding area. The
task of the emergency responders is to protect the scene before crime scene investigators arrive to scrutinize the scene further. The emergency
responders will explore the physical conditions at the crime scene, such as hazardous or toxic materials, electrical problems, the weather, the structure
of the crime scene, and any dangerous people or animals in the surrounding area. If there are any dangerous conditions that exist, they should be
reported to the officer in charge so that the conditions can be addressed and corrected so that the crime scene investigation can take place. Sometimes,
but not often, personal protective equipment will be utilized when working on a scene with hazardous conditions. Personal protective equipment

The Importance Of The CSI Effect On Crime Scene Investigation
Introduction Television has been around for years making money off of the public's interests. Starring shows such as CSI Miami, Forensic Files,
Cold Case, Bones, and many more demonstrate the procedures of forensic science at active crime scenes. However, these shows have given the
wrong perception of forensic science and the procedures to investigating an active crime scene. These television shows have made a lasting impact on
the public's perception of Crime Scene Investigation still today. Often times these shows have made it difficult for judges, attorneys, lawyers, and
juries to understand forensic science. CSI Effect Crime Scene Investigations are fascinating to the public and have been portrayed on television for
many years. These television shows have influenced how the public perceives the procedures of investigating crime scenes. Forensic science and
investigating a crime scene is a very complex and unique career. Television has exaggerated and wrongly influenced the perception of forensic science,
crime scene investigation, and procedures in criminalistics. The effect that these crime scene television shows have on the public is called the CSI
Effect (Shelton, 2008). The CSI effect can lead to jurors wrongly acquitting an individual because they believe the job wasn't thorough enough. There
are more than 100 million viewers who watch television shows about scientific evidence in criminal cases (Shelton, 2008). The general public assumes

Background Information: Forensic science once thought a Pseudo–Science is now a staple in the arsenal of weapons that police forces utilize daily.
Recently Williams and Weetman refer toforensic science as something that is recurring throughout an investigation. It is utilized at the scene of the
crime, in the laboratory, in the briefing room, in interviews and in the courtroom (2013, p. 381). Throughout their research Williams and Weetman take
note of the ever changing combinations of institutional structures, dynamic processes and agents in the routine usage of forensic science in policing. In

The small amount of research that attempts to assess the benefits of forensic science is said to fall short of its intended goal. Williams and Weetman
(2013) propose numerous reasons for forensics falling short. Some are the reduction of extant studies which view police and forensic process as linear
rather than separate entities; said studies also have failed to provide a sense of how forensic science is enacted in the course of an investigation.
(Williams and Weetman 2013). The existing research fails to acknowledge the expertise and skill of those who perform forensic tasks throughout the
course of an investigation. The current study seeks to clarify the role of CSI practices by looking further into trace and contamination avoidance. Along
with trace and contamination avoidance, CSI work in general is studied in an effort to further the understanding of how it works between the field and
in the courtroom.
Trace evidence, the term given to physical evidence that is the result of transference of material from a victim or a crime scene to something else

There is also the impact on the general public as a whole. For instance, those watch police investigation dramas on television is generally their only
source of knowledge on how the process works. "Individuals take information they already have, simplify the complexity of an issue, and derive a
steadfast conclusion" (Stevens, 2010 pp. 6–7). What this means is that common people look at a problem and make an instant resolution or in other
words, make a prediction without knowing all the evidence or going through the deductive process. Individuals see the repetition in the dramas leading
them to assume what is going to happen. The thoughts of these individuals are the ultimate building blocks to the CSI Effect. What is has ultimately
come down to is that "the public has views shows that have hypothetically solved real–life cases before the actual cases have gotten to trial, so some
jurors believe they have gained 'insight' from the media's amateur sleuthing" (Ramsland, 2006, pp.

Have you ever seen on a television show or on the news where a suspect was arrested or fined when in the end it was not even that person who
committed the crime or accident? Many incidents have resulted in this due to false information given from eyewitnesses that experienced the scene.
This is why forensic and crime scene investigations are an important aspect because it aids in minimizing the potential suspects that have been
presented already. Scientific data gathered from an investigation is not necessarily more important, but it has a higher percentage of accuracy and
reliability than eyewitness accounts.
The emotions and memory of the mind can mess with the results that are taken from the eyewitness accounts. According to Barbara Tversky,... Show

According to New York Times, "about 75 percent of DNA–based exonerations have come in cases where witnesses got it wrong." DNA testing in labs
and on the crime scene are exact and not made up. While some researchers may say that eyewitness accounts are valuable evidence, they are not as
reliable as scientific studies done by professionals. Farahan Sarwar from Science Daily says, "Criminals are getting increasingly canny. They rarely
leave any clues. Therefore, eyewitness accounts are still the most important thing the police have to go on." However, the police must be aware of how
much importance they attribute to the eyewitness accounts for the concern of false material for the case. Thus, forensic science can still be used for
about every situation in a crime scene investigation. For example, autopsy, fingerprint identification, DNA testing, weapon testing, and computer
database. According to Reference, there are machines that are able to tell what weapon was used based on ammunition, how the shot was taken, and
how much of an impact was put on the person. This is helpful when an eyewitness was not able to spot the gun type. In the end, eyewitness accounts
are a helpful start for the investigation, but scientific research is a more effective and dependable way to resolve

along as with the attackers was well kept and labeled that it hardly escaped Carl's team. Also, the gun, which was the main weapon used in the attack
was kept well enough to the extent that details about the ballistics and GSR reports conducted in determination of whether it was a murder or suicide
were intact seven years later. This level of documentation is very significant... Show more content on Helpwriting.net ...
First, the interrogators should keep an open mind regarding the case, refraining from making any judgments that may influence the process of
investigation. In this regard, the investigating officers ought to have questioned Pam's children first regarding the account, and probably administered a
polygraph test on them to determine whether they had been couched to say anything.
Second, for all adults, a polygraph test would have been necessary in determining whether their statements were true, considering the level of
relationship that each of the adults had with Hendrick. Documentation during the interrogation ought to have been in the form of note–taking,
ransacking the crime scene for any valuable piece of information, photography, video or audio recording and possibly generation of computer models
of the crime scene (Fisher & Fisher, 2012). A look into at Pam's death case, none of these materials surfaces when Carl takes on the case in 2008.
During interrogation, the investigators are supposed to be alert when listening to testimonies. It is obvious that details of the testimonies are

Crime Scene Evidence Crucial Police Investigations

  • 1. Crimes Scenes And Evidence Gathering Underpin Every Police... Crimes scenes and evidence gathering underpin every police investigation. From the moment police arrive to a scene to the moment a verdict is decided upon the offender, the way in which crime scenes are established and evidence gathered holds significant weight on the outcome. By discussing the provided scenario along with the issues surrounding the establishment of crime scenes, the way in which evidence is gathered, legislative and policy powers and requirements, and the phenomena of Locard's Principle, we can establish an understanding of best practice which ultimately will positively impact the final outcome of a verdict. General identifying statement Ensuring a crime scene is established in the wake of an incident lays the foundation for an effective investigation. Horswell, J. (2004) describes a crime scene as simply a place which is connected to a crime or incident, either primary or secondary in nature. A primary crime scene being that of where the crime occurred and where the majority of evidence can be found, while secondary being that of where evidence relating to the crime may exist elsewhere (p. 32). In relation to the provided scenario, the house in case is the primary crime scene; as this is where the incident has occurred and

  • 3. Death Investigation : A Guide For The Scene Investigator Death investigation has been performed for a considerable length of time in all social orders, albeit not generally by medical experts .The relationship of law and medicine goes back to the Egyptian society as early as 3000 B.C. The English coroner framework was said in documentations around the twelfth century B.C. Despite the fact that the essential objective of a death investigation is to build up the cause and manner of death, the death investigation part expands much more remote. While without a doubt the dead can 't take advantage, the quality in death investigation is to benefit the living and future eras. In a culture that values life, clarifying the demise in an open gathering is essential for many reasons ("Journal of the American Academy of Psychiatry and the Law Online"). In June 2011, the United States Department of Justice released a revised and updated edition of the 1999 version of the manual, titled Death Investigation: A Guide for the Scene Investigator. This manual discusses proper guidelines for conducting death investigations in all stages of the investigation, what investigative tools and equipment are needed, and step by step instructions from when arriving at the crime scene to departing. The manual gives a decent synopsis on how investigations including death ought to be drawn closer, yet does not expand much on potential issues that would be tended to, why certain methods are so imperative, and is ambiguous in a few zones ("A Guide to Death Scene ...

  • 4. CSI: Crime Scene Investigation The TV series of CSI: Crime Scene Investigation is a popular literature of today's entertainment delving into the concept and genre of detective/crime fiction. With multiple seasons under its belt the popular works has been able to create multiple concepts of this detective literature drawing on from writers creativity as well as the realistic crimes that have transpired past and present within our societies, evident in the text study of CSI season 1 episode 9 "Unfriendly Skies". This popular literature uses structuralist film theory and forms of realism to emphasise how literature can convey meaning and understanding through the use of narrative form and conventions. The narrative structure of the show is influenced of the classic crime ... Show more content on Helpwriting.net ... William W. Stowe continues to create an understanding of the genre where "Detective fiction tends to affirm rather than question, to take social structures, moral codes and ways of knowing the given, rather than subjecting them to thorough, principled criticism.

  • 5. DNA In Crime Scene Investigation Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect's guilt or innocence (Butler, 2005). The method of constructing a distinctive "fingerprint" from an individual's DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA ... Show more content on Helpwriting.net ... Each person inherits two copies of these markers from his or her mother and father, so a higher similarity denotes a closer biological relationship. The probability of two samples matching is around one in a billion (dna.gov). DNA profiles are compiled by using gel or capillary electrophoresis to separate samples into a pattern distinctive of the subject's DNA based on ionic charge, size, or mobility. Usually, samples in the database are searched at moderate stringency, which requires that all alleles between the two samples match, but the number of alleles can vary, accounting for DNA contamination or degradation. Partial, or candidate, matches are samples that have a similar number of alleles in the forensic profile but are not exact, and are used in familial DNA searching to find close biological relatives of the original forensic profile. Other evidence is used to determine relatives, including Y chromosome analysis, which traces family relationships based on the fact that the Y chromosome is transmitted directly between a father and his sons; age; and geographic location. The process is based on the principle that first–order relatives have closer DNA profiles than unrelated individuals, and also on the sociological assumption that criminal tendencies appear in families; according to "the Bureau of Justice Statistics Correctional Populations ...

  • 6. Crime Scene Investigation Essay At a crime scene, insects can provide important pieces of information to criminal investigators, including estimating the post–mortem interval (PMI) and determining where the crime took place. This is only possible, however, if the local insect fauna is known, thereby facilitating the need for local insect population surveys at both the morphological and gene levels. Although flies (order Diptera) are one of the first and most prevalent necrophagic insect species found associated with a corpse, beetles (order Coleoptera) are also a forensically relevant insect that can play a significant role in crime scene investigations. In this study, the objective was to survey the Coleoptera population in Lyon County, Kansas during the early spring. Insects were collected using light traps during the evening hours and DNA was isolated from each collected specimen followed by amplification of the cytochrome oxidase I (COI) gene. The cytochrome oxidase I (COI) gene is known to be as a standard barcode gene. (CBOL, 2010) This barcode gene is a 648 base pair mostly found in all animals including flies, ...

  • 7. Police Scene Investigation And Reconstruction General Identifying Statement Crime scene investigation and reconstruction are both central aspects in the study of policing. By definition, a crime scene is a scene or place where an offence has been committed, and the site where forensic evidence is to be gathered in the pursuit of investigating the offence (Fisher, 2012, p.10). Fisher goes on to clarify that a crime scene may refer to a physical place that may provide potential evidence to an investigator. This is not limited to a location but rather may include a include a person's body, any type of building, vehicles, places in the open air or objects found at those locations. Fisher elaborates; explaining how hoth forensic and scientific techniques are used in order to preserve and obtain evidence of crime at the crime scene. (Fisher, 2012, p. 13). Lee and Palmbach (2001) point out that the processes involved in examining a crime scene does not need to be sophisticated or elaborate; instead, investigators need to concern themselves with adhering to the fundamental principles and procedures within crime scene investigation. It is important to remember that there is not a comprehensive plan or sole guiding principle when it comes to processing crime scenes (Pepper, 2010, p. 101). This being the case, exploring different protocols and methods that assist in forming a logical plan towards crime scene investigation is crucial in policing.

  • 8. Crime Scene Investigation Research Paper Like you see in the Crime scene investigation shows like CSI and Bones, there are many things that go into investigating shows a lot of those things happen but it takes much longer than forty or sixty minutes to solve the crime. While crime scene investigating is very serious job, collecting evidence at crime scenes requires education and knowing of what you're doing, requires hard work, and it can be difficult to perform this job. What is crime scene investigation? Crime scene investigation is the use of physical evidence at the scene of the crime and the use of of the deductive and inductive reasoning to gain knowledge of the events and of the surrounding crime. Crime scene investigating is a big combination of Science, logic and law. ... Show more content on Helpwriting.net ... Homicide detectives only investigate and focus on Homicides. College educations are recommended but not required. Murder detectives collect evidence like fingerprints DNA and stuff like that. They interview suspects and witnesses who may have information for the murder. There are two types of crime scenes. The primary crime scene is where the crime scene is where the crime actually occurred. for example if a bank get robs that is the primary scene and the getaway car and the lair are the secondary scene. primary crime scenes are usually more helpful. while secondary scenes sometimes are the only thing that criminologists have to work with. For example this may be where a serial killer dumps a body. So investigators may not be able to prove where the actual murder occurred. which means they only find evidence at the secondary scene which could lead to the primary scene or prove that is where the crime happened. For example you may find a hair or a fiber at a scene that could lead to a specific place or specific shirt or carpet. Overall investigators prefer primary scenes because it's ...

  • 9. An Investigation Of The Crime Scene Units . Listed were searches on how to make homemade chloroform, how to do a "fool proof" strangulation, and how to get rid of a body. (Casey Anthony Case, 2013) It is not clear who actually made these searches. Cindy admits she was trying to look up chlorophyll and ended up searching for chloroform by mistake. All in all, this seemed unlikely to investigators but they did not have the definitive proof needed to charge anyone. At this time they still only had Casey as a person of interest. The entire family refused to take a polygraph test. It was nearly six months after Caylee went missing before any new evidence was found. On December 11, 2008, meter reader Roy Kronk decided to take a little break from work. He walked into the woods... Show more content on Helpwriting.net ... The clothing was similar to clothing from Caylee in size and description. Most notable was the baby blanket. She could faintly make out the character Winnie the Pooh. Photographs of Caylee's room and pictures of Caylee as an infant show here laying on the same patterned blanket. Wrapped tightly around the skull were three layers of duct tape. Dr. Garavaglia was able to note that this was done prior to any decomposition of the body. This was because the mandible remained attached to the skull after decomposition had occurred completely. (Casey Anthony Trial, 2011) Usually, once thesoft tissue breaks away, there is nothing holding the lower jaw to the upper skull portion. The tape had held the mandible in place and all of the baby teeth were still in place. This is fairly unusual because baby teeth are temporary and do not have true roots holding them in once the tissue is gone. (Casey Anthony Case, 2013) The tape had been wound through the child's hair and was still clinging into the tape. Over the mouth area, there was a heart shaped sticker. Investigators found similar stickers in Casey's room. This pointed even more to the remains belonging to Caylee Anthony. Finally a definitive answer came in. The DNA results finally came back. The findings were that the remains did in fact belong to Caylee. Now it was Dr. Garavaglia's job to figure out how this young girl lost her life. ... Get more on HelpWriting.net ...
  • 10. The Influence Of CSI: Crime Scene Investigation The CSI effect is the phenomenon in which jurors hold unrealistic expectations of forensic evidence and investigation techniques, and have an increased interest in the discipline of forensic science because of the influence of CSI–type television shows. This effect includes raising the state's burden of proof because of jury expectations that forensic evidence should always be discussed at trial, and the belief that forensic evidence is never wrong. The show CSI: Crime Scene Investigation provides inaccurate information by closely relating to the reality of the investigation, but accelerating and exaggerating long processes in the criminal justice system. For example, searching databases for fingerprints and other DNA evidence can take months, whereas in the show it takes only minutes or hours. Also, an increase in demand for forensic evidence for a conviction has placed a higher burden of proof on the prosecutors. Whereas, forensic evidence is not always available or necessary for a ...

Sexting is a new type of crime, thus the laws regarding nude images of minors have been adjusted, so that voluntarily sending an explicit photo of oneself to another minor does not convict them as sexual predators and sentenced with a felony. Defining laws against sexting can be challenging for the legislators, nonetheless is necessary. If the laws are not modified, many minors' lives can be damaged by simply sending or receiving a naked photo of their significant other. Also, true sexual predators can take advantage of the loopholes and commit a heinous crime.

My favorite television show is The First 48, my favorite movie is The Silence of the Lambs, and my favorite book is The Body Farm. Therefore, I was excited to have the opportunity to take this course and learn even more about the subject of forensics. This essay gives a summary of N. E. Genge's book, The Forensic Casebook: The Science of Crime Scene Investigation, and includes the things I disliked and liked about the book.

I really enjoyed the about unique cases–such as the man killed by the falling icicle (Genge 79). In another story, young woman was found hanged, and police were charged with the task of determining if she had committed suicide or if she was the victim of a homicide. After much investigation, the cause of death was listed as an accident. Evidently the young woman's friend stated that she had helped tie the knot on the rope–never believing that the young woman would actually kill herself (Genge 92). After the ruling, the police were not entirely convinced that it was an accidental death even though no sign of struggle was evident; however, there was insufficient evidence to prove otherwise (Genge 92). The discipline I enjoyed reading the most about was the use of animal examiners–dogs. The author was very thorough with the subject, even going so far as to explain why dogs are normally used instead of other animals such as pigs, cats, and ferrets. According to Genge, dogs enjoy working because of the praise earned, whereas pigs are easily sidetracked by the smell of food, cats "don't like to work," and the attention span of a ferret is almost non–existent (Genge 210). Another interesting fact about dogs is that the canine nose is adept at sniffing out old ... Get more on HelpWriting.net ...

While they are going through a walk–through, they may have to construct theories about what happened in the crime scene based on visual examination. Investigators have to take photographs of the scene and will later on be collected. Taking photographs of the scene will help them solve the crime because there are some points of the investigation that investigators may have overlooked evidence, and that evidence could be found in the photographs. After taking photographs of the scene, they will start to collect clue and evidence that may lead them to their possible suspect(s). What they may find in the crime scene are fingerprints which can be done using colored powder and a brush, other thizngs such as blood, firearms, hair, glass and many more things that can be found in the crime scenes. After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime scene investigators will look at the photographs and connect their theories based on the crime that occurred. The forensic scientists will also examine the victim's clothes, while the medical examiner will analyze the victim's body for more clues and evidence that they may find and they will all be doing this in the crime lab.

The sketcher must also draw everything else in the crime scene in order for the computer in the forensics lab to get the most accurate measurement.

When detectives are interviewing a suspect but know they don't have enough evidence to get a warrant for DNA sample the detective can gather evidence from objects the suspect may have come into contact with in the interview room. When the detective interviews a suspect they will give the suspect a glass of water hoping that the suspect will drink out of it and the detective can then send that glass to the forensics and get the DNA tested that is on the glass and see if it is a match to the crime.

There are three kinds of sciences to look at: Pure, Applied, and Junk. Pure science defined as; systematic observation of natural phenomena solely for the discovery of unknown laws relating to facts; the study of science alone, not including its relations to other subjects (dicionary.com, 2018). This science looks at facts that one derives from mathematics and logic; the natural science. The second is Applied science. Applied science is: the discipline dealing with the art or science of applying scientific knowledge to practical problems; "he had trouble deciding which branch of engineering to study" (Farlex, 2018). This science deals with facts from machines, inventions, and technology. The third is junk science. Junk science is: faulty scientific information or research, especially when used to advance special interests (dictionary.com, 2018).

The steps one follows for this process include: Observation, hypothesis, experiment, conclusion. If one does not find the truth the first time, they go back and repeat these steps.

The search of blood is mostly done by close observation of investigators, however, sometimes blood in the crime scene will be wiped out by the murderer, or, sometimes the amount of blood will be too little to be observed without the assistance of other substance. For this kind of situation, luminol can be used in order to help criminalists to detect blood in the crime scene. Luminol (5–Amino–2,3–dihydro–1,4–phthalazinedione) is a compound that made up with carbon, hydrogen, oxygen and nitrogen, the chemical formula of luminol is C8H7O3N3, it is in a form of powder at room temperature and room pressure. The chemical reaction of luminol and the reactant is a chemiluminescence reaction, which emits strong blue light during the reaction. Luminol can't be used alone, in order to use it, criminalists must first activate it first. Luminol needs to mix with a strong oxidizing agent such as hydrogen peroxide (H2O2). Other than a strong oxidizing solution, a basic solution is also needed, for the basic solution, alkali like sodium hydroxide can be used.

In this way, the trepidation is that the TV show is at last influencing the results of trials – and not in a great manner.

Protection of the crime scene starts when the first responding officer arrives at the scene. Often times, the police officer's "swoop and scoop" idea prohibits all of the evidence and identification to be discovered. "Swoop and scoop" is the process that many police officers take at crime scenes; they will approach the scene and very quickly "find evidence" so that they can proceed to the next call. Police officers, firefighters, and emergency medical workers are the first to arrive on scene to assess any health concerns and make sure there are no "perpetrators" in the surrounding area. The task of the emergency responders is to protect the scene before crime scene investigators arrive to scrutinize the scene further. The emergency responders will explore the physical conditions at the crime scene, such as hazardous or toxic materials, electrical problems, the weather, the structure of the crime scene, and any dangerous people or animals in the surrounding area. If there are any dangerous conditions that exist, they should be reported to the officer in charge so that the conditions can be addressed and corrected so that the crime scene investigation can take place.

Williams and Weetman (2013) propose numerous reasons for forensics falling short. Some are the reduction of extant studies which view police and forensic process as linear rather than separate entities; said studies also have failed to provide a sense of how forensic science is enacted in the course of an investigation. (Williams and Weetman 2013). The existing research fails to acknowledge the expertise and skill of those who perform forensic tasks throughout the course of an investigation.

Therefore, eyewitness accounts are still the most important thing the police have to go on." However, the police must be aware of how much importance they attribute to the eyewitness accounts for the concern of false material for the case. Thus, forensic science can still be used for about every situation in a crime scene investigation. For example, autopsy, fingerprint identification, DNA testing, weapon testing, and computer database.
