“Create your own crime” Project Two The story: A murder has been committed in which there are multiple suspects. You, the investigator, examine the crime scene and find DNA evidence of the perpetrator on the victim. You analyze the DNA and get its fingerprint. You obtain a DNA sample either by luck or through a legal warrant. You compare their DNA to your sample. A positive ID is made from your efforts and with the motive and method linked to the correct suspect you arrest the perpetrator. The assignment: This assignment is much like the project you did during the CSI unit at the beginning of the year. You will use your already created mock crime and present a Power point of how the crime was solved. What will be different is that the previous Ppt only described the initial, preliminary investigation and won’t carry me through the outcome of the crime. This project will summarize the entire mystery. Also, in this investigation there will be multiple suspects biologically related to each other. Thus, you will have to create several motives and plausible opportunities allowing for the killer to commit the crime. Your murderer will have left a sample of his/her DNA on either the victim or the murder weapon: blood, sweat, hair; your choice but there must be a plausible reason for it being there. A murderer’s blood does’t just magically get left behind so be able to explain it. If you need some ideas for how DNA can get left behind, check out this chart I found in the textbook: Which suspect will be arrested will be determined by testing the DNA evidence and comparing it with the suspects’ DNA. You will have to figure out how your investigator gets a sample of their DNA. I doubt the suspects would give it to you voluntarily. You can either obtain a warrant for the DNA (we’ll learn later what you need to do) or you can get lucky and find it as part of your investigation. You will have to include prints of all DNA tested: the evidence that was found at the scene and the samples obtained from your suspects to prove that they match. Obviously, you won’t be able to do an actual DNA test; kits can be expensive. But you can describe how the procedure is done and create mock prints on graph paper. These are what DNA profiles look like: A PCR DNA print A gel electrophorus DNA print Surely, you can make something that looks like one of these by coloring in graph paper. We’ll learn how to do the tests. I will expect a description of the procedure much like how it was part of your story. So, to summarize: You are creating a Powerpoint that will include: 1. A photo and description of the victim, the murder weapon, biological evidence of the perpetrator, and other relevant evidence found at the scene. Multiple slides may be needed but this part doesn’t have to be as detailed as the first presentation. A Final Sketch of the your crime scene needs to be included. 2.

1. “Create your own crime” Project Two
The story:
A murder has been committed in which there are multiple
suspects. You, the investigator, examine the crime scene and
find DNA evidence of the perpetrator on the victim. You
analyze the DNA and get its fingerprint. You obtain a DNA
sample either by luck or through a legal warrant. You compare
their DNA to your sample. A positive ID is made from your
efforts and with the motive and method linked to the correct
suspect you arrest the perpetrator.
The assignment:
This assignment is much like the project you did during the CSI
unit at the beginning of the year. You will use your already
created mock crime and present a Power point of how the crime
was solved.
What will be different is that the previous Ppt only described
the initial, preliminary investigation and won’t carry me
through the outcome of the crime. This project will summarize
the entire mystery.
Also, in this investigation there will be multiple suspects
biologically related to each other. Thus, you will have to create
several motives and plausible opportunities allowing for the
killer to commit the crime.
Your murderer will have left a sample of his/her DNA on either
the victim or the murder weapon: blood, sweat, hair; your
choice but there must be a plausible reason for it being there. A
murderer’s blood does’t just magically get left behind so be
able to explain it.

2. If you need some ideas for how DNA can get left behind, check
out this chart I found in the textbook:
Which suspect will be arrested will be determined by testing the
DNA evidence and comparing it with the suspects’ DNA. You
will have to figure out how your investigator gets a sample of
their DNA. I doubt the suspects would give it to you
voluntarily. You can either obtain a warrant for the DNA (we’ll
learn later what you need to do) or you can get lucky and find it
as part of your investigation.
You will have to include prints of all DNA tested: the evidence
that was found at the scene and the samples obtained from your
suspects to prove that they match. Obviously, you won’t be able
to do an actual DNA test; kits can be expensive. But you can
describe how the procedure is done and create mock prints on
graph paper.
These are what DNA profiles look like:
A PCR DNA print A gel electrophorus DNA
print

3. Surely, you can make something that looks like one of these by
coloring in graph paper. We’ll learn how to do the tests. I will
expect a description of the procedure much like how it was part
of your story.
So, to summarize:
You are creating a Powerpoint that will include:
1. A photo and description of the victim, the murder weapon,
biological evidence of the perpetrator, and other relevant
evidence found at the scene. Multiple slides may be needed but
this part doesn’t have to be as detailed as the first presentation.
A Final Sketch of the your crime scene needs to be included.
2. Photos, descriptions, and motives of the suspects as
well as reasons for suspecting them (where they
found at the scene of the crime holding the bat?)
and how do you know their motive (interviews with
neighbors? Confessions?).
3. The DNA print of the biological evidence found at the
crime scene and a description of the procedure
(gel vs. PCR)
4. Photographs and descriptions of the samples containing the

4. suspects’ DNA and an explanation of how you
managed to get a hold of their DNA. Their DNA
CANNOT be illegally or forcefully obtained. Warrants for
their DNA must be filled out and included. If you
found their hair on a brush, how did you get the
brush? If you searched their house, you must include a
search warrant. If they gave you a blood sample,
you must include a warrant permitting you to get
their blood. All paperwork must be included in your
presentation.
5. DNA prints of both (or more) suspects. You don’t have to
write up a second description of the test’s
procedure. Once is enough.
6. A third slide of prints placing the first print side by side
with the suspect whose
DNA you believe matches the DNA found at the scene.
The two must be identical.
7. A final slide announcing who was arrested that summarizes
why they were arrested including motive, method,
opportunity, and DNA proof.
