This document provides an analysis by an FBI profiler of the Jack the Ripper serial killings that occurred in London in 1888. Some key points:
1. The victims were all female prostitutes who drank heavily, making them high-risk.
2. Autopsies showed the killer acted swiftly and was able to control the victims, and displayed some anatomical knowledge by removing organs.
3. The crimes occurred in the early morning within a quarter mile of each other, forming a triangle, indicating a primary and secondary comfort zone for the killer.
4. The analysis provides insights into the killer's traits, behavior and rituals based on the victimology and crime scene evidence.
The Kray Twins, Reggie and Ronnie Kray, were notorious British gangsters who ruled organised crime in London's East End during the 1950s and 1960s. Ronnie suffered from paranoid schizophrenia. As young men, they were involved in armed robberies, arson, and other violent crimes. In their criminal careers, they acquired clubs and properties through protection rackets, hijackings, and robberies. During the 1960s, they gained celebrity status by mingling with celebrities, but were eventually arrested in 1968 and convicted of murder, receiving life sentences. Ronnie spent his remaining years in a secure hospital due to insanity, while Reggie died in prison in 2000.
Fred West had a troubled childhood, experiencing incest and bestiality at a young age. He had several accidents later in life that seemed to change his personality and make him prone to fits of rage. He was convicted of molesting a teenage girl at age 20. Rose West also experienced abuse and trauma as a child. She met Fred West as a teenager and they later married and killed at least 10 women and girls together between 1967 and 1987, burying many of the victims in their home. They were both eventually arrested and convicted for their crimes.
Serial Killers Psychology PresentationPietro Solda
Serial killers are typically single white males with unstable family histories and psychological issues. They are often intelligent but have difficulties with employment and relationships. There are two main types - organized killers who plan their crimes, and disorganized killers who act impulsively. Motives include lust, thrill-seeking, gaining power or profit. Lust killers in particular derive sexual pleasure from torture and mutilation of victims. Notable serial killers profiled include Jeffrey Dahmer, who engaged in cannibalism and necrophilia, David Parker who tortured victims in a torture chamber, and Richard Chase who was driven by delusions involving blood and organs.
The National Investigations Committee on Aerial Phenomena (NICAP) is forming to investigate UFO sightings and determine if "flying saucers" exist. The committee is led by Thomas Brown and plans to elect a board of governors. It will operate as a privately funded fact-finding group to serve the public interest. Membership levels range from $7.50 to $1,000 and the goal is to raise $2-3 million for research.
The document provides a 3-page sworn statement from a pilot describing his efforts over 3 days in July 1947 to locate and photograph reported flying discs or saucers near Mt. Rainier and Mt. Adams in Washington state. On each of the 3 days, the pilot took different aircraft on searching missions covering territory in Idaho, Washington, and Oregon but found nothing. He observed rapidly forming cumulus clouds near Boise, Idaho on the third day of searching but saw no unusual objects.
This document is a response from the FBI to a correspondent regarding an organization called the Committee on Aerial Phenomena. The FBI has not investigated the organization and has received no complaints against them alleging violation of any laws under the FBI's jurisdiction. The FBI provided the correspondent with several pamphlets about combating communism, but the document contains no identifiable information referring to the correspondent.
A woman reported seeing an unidentified flying object on April 5, 1956 while driving near Henderson, North Carolina. She described the object as very bright and luminous, shaped like an egg and making no sound. She was unable to determine the exact size but estimated it was less than 25 feet away. The letter seeks John Edgar Hoover's input on whether any similar reports were made to the FBI regarding two men who supposedly came from Venus and met with a journalist in Los Angeles in March 1953.
This document is an exchange of letters between the FBI and local law enforcement discussing recent cattle mutilations in Nebraska and surrounding states. The local agency provides news articles about the incidents and requests any information the FBI can provide about the cause. The FBI acknowledges receiving the request and will investigate whether the incidents fall under its jurisdiction.

A woman in Twin Falls, Idaho reported finding an unusual disc-shaped object in her backyard around 2am. The object was described as being circular and saucer-shaped, about 30 inches in diameter. It had domes on each side attached by bolts, and appeared to have wiring and unknown components inside. Local police took possession of the object and notified the FBI and local army authorities.
The FBI has joined the investigation of over 1,000 animal mutilations linked to UFOs across 11 western states. The mutilations involve cattle and horses being found with surgical precision wounds and removed body parts stretching back to the 1970s. In March 1979, the FBI was instructed to investigate 15 cattle mutilations on Indian reservations in New Mexico at the request of the Justice Department. The FBI conference determined that one agency, the District Attorney's office in Santa Fe, would coordinate the investigations across jurisdictions. To date, the FBI investigation has not identified who or what is responsible for the mutilations.
1) The human mind has difficulty objectively processing highly unusual or deceptive data, which can leave intelligence agencies blind to surprises.
2) Scientific studies show the human response to strange phenomena involves an initial objective observation followed by shock and a tendency to interpret the data in a way that fits preexisting psychological structures.
3) This flaw in evaluating surprising information has led to military defeats throughout history when adversaries exploited an inability to believe an unexpected tactic was possible.
The letter summarizes observations from the Ground Observation Corps in Franklin County, Indiana regarding flying saucer phenomena over the past 5 years. Several residents have reported sightings of unusual objects in the sky to the author. The author believes they are dealing with a fascinating phenomenon that is too big for one person to investigate alone. They have collected reports and observations in the hopes that flying saucers will eventually land, confirming that they are physical objects.
This document discusses a report from a prison inmate in Montana of a UFO sighting in Washington state. The inmate said they saw a silver object streaking across the sky that disintegrated, leaving a pillar of "gas". The local FBI office did not take further action due to the delay in reporting. The document also discusses communication between the FBI and Army Air Forces regarding their cooperation on UFO investigations and concerns about limitations and characterizations in the Army's instructions.
This document provides an overview of mysterious cattle mutilations that occurred across 22 US states in the 1970s. Over 1,500 cattle were found killed and mutilated with strange surgical precision, often missing eyes, tongues, and genitals. Rumors spread of satanic cults or UFOs being responsible. The cases attracted interest from UFO researchers and the investigation uncovered alarming letters from a convicted criminal, Kenneth Haston, who claimed to have information about a secret satanic society behind the mutilations.
The NSA report from 1969 warns that UFO sightings by reputable witnesses indicate that UFOs are a real threat and not just hoaxes. The report cautions that if UFOs are extraterrestrial, it could have serious survival implications for humanity. It urges taking UFOs more seriously and being prepared in case of a surprise invasion, citing examples like Pearl Harbor where lack of preparation led to defeat.
The document appears to be a report of a UFO sighting, but contains minimal useful information. It lists basic details requested for a report such as date, time, location of observation, number of objects seen, color, shape, direction and distance from observer. However, most of the responses are illegible or have been redacted, so the summary provides no additional context or specifics about the sighting.
This letter from the US Air Force responds to an inquiry about UFOs. It summarizes that Project Blue Book, the Air Force's UFO investigation program, was terminated in 1969 based on studies concluding UFOs did not represent technological developments beyond current scientific understanding and there was no evidence they were extraterrestrial vehicles. All Project Blue Book documentation was transferred to the National Archives. Since termination, no evidence has emerged warranting renewed Air Force investigation of UFOs.
Two Iranian F-4 Phantom jets encountered several unidentified flying objects (UFOs) late one night. The first jet lost instrumentation and communications when approaching a bright object, but systems returned to normal when it turned away. A second jet locked radar on a UFO and observed it maintain distance. When the jets pursued additional detached objects, they again lost systems. Upon returning to base, the jets had difficulty landing due to interference and magnetic/navigation fluctuations. The next day at the location one object was believed to have landed, a house's inhabitants reported seeing lights the previous night.
This document provides a summary of Operation Majestic-12, a secret U.S. government operation established in 1947 to investigate unidentified flying objects (UFOs) and possible extraterrestrial biological entities. It lists the members of Majestic-12 and describes early UFO sightings that prompted the operation's formation. The document also summarizes early Majestic-12 activities, including attempts to study crashed UFOs and recovered alien bodies. It notes the group's conclusion that at least some UFOs appeared to be of extraterrestrial rather than human origin.

VICTIMOLOGY
In each homicide, the victim was aprostitute with a
reputation ofdrinking quite heavily. These two ingredients
place the victim in a"high risk" category. By "high risk," we
define this as someonewho is very likely to be thevictim of
violent crime. From aninvestigative perspective, this makesit
extremely difficult inreference to developing logical suspects.
From aforensic viewpoint, if any evidence is obtained such as
hairs andfibers, semen, etc., law enforcement would not know for
certainif this evidence did in fact comefromthe subject.
One hundred years ago, prostitution was not as
organized asit istoday, where wehave pimpscontrolling,
monitoring, and protecting theirstables. During the "Jack the
Ripper"era,women worked independently.A femaleprostitute who
drank heavily was looking for trouble. Wewouldsuspect that
there werenumerous instancesof these womenbeingphysically
assaulted, raped, and ripped off.
F
Prostitutes 100 yearsago did not dress differently
thanotherwomen at that time.In mostcases, they performed
their "services" in dark alleys or in"flop" houses. The
prostitutes targetedby Jackthe Ripperwerenearlytwice the age
ofprostitutes soliciting today. Theywere not particularly
attractive and other thantheir age,there wereno striking
similarities between them.It is notedthat the lastvictim was
25.!
The "Jack the Ripper" victims were targeted because
they werereadily accessible. Jack the Ripper didnot haveto
initiate the contact. This wasdonefor him bythe prostitute.
This is an important feature in acase such asthis and will be
addressed later onin this analysis under"Offender Traits and
Characteristics."
MEDICAL EXAMINATION i
As statedearlier, the medicalexaminations conducted
at that time werenot verythorough whencomparedtoautopsy
examinations conducted todayby experienced forensic
.pathologists. However, evenin someparts ofthe United states
today, autopsy examinations aresomething lessthan desired.
The primary areas notedin this analysis were as
follows:
l. No evidence ofsexual assault. '
2. Subject killed victims swiftly.

CRIME ANDCRIME SCENEANALYSIS
with the exception ofthe lastcase, all victims were
killed outdoors. All victims were killedswiftly, withthe
victims consequentlyreceiving postmortemmutilation. All
homicides occurredwithin onefourthof a mile fromeach other
and occurredeither onFriday, Saturday,or Sundayduring early
morning hours.After thefirst homicideat WhitechapelStation,
the subjectmoved slightlyacross townonefourth ofa mile!.
If a line isdrawn from crimescenes 2,3, 4,and 5,atriangular
configurationisformed. Thisisobservedinother types of
serial crimes. This triangularconfigurationisviewed as a
- secondarycomfort zonefor the Ripper. Thismovement iscaused
when asubject believesthat theinvestigationisheating up in
his primarycomfort zone.The primarycomfort zonewould bethe
location ofthe firsthomicide in thevicinity of Whitechapel
station. It isthe opinion ofthis crimeanalyst thatthere were
other attacksin theWhitechapelareathat either wentunreported
or for some reasonwere notconsidered byauthorities to be
crimes of Jack the Ripper.

1: I0 /.
Some criminologists and behavioral scientists have
written in the past that subjects will maintain their modus
operandi and that is what links socalled "signature crimes."
This conclusion is incorrect. A subject will change his modus
operandi as he gains additional experience. This is learned
behavior. However,the personaldesires andneeds ofthe subject
areexpressed in the ritual aspect of acrime. The ritual is
something thathe mustalways dobecause it isthe acting out of
the fantasy. With Jack the Ripper, the target selection, the
approach, the method of his initial attack, are his modus
operandi. What takes place after this is the ritual. The ritual
may becomemore elaborate as*was in the last homicide case.
Here, the Ripper had time to act out his fantasies. As
investigators, weshould notnecessarily expectthe sametype of
homicides in the future, particularly if subsequent victimsare
killed outdoors. Once again,he wouldnot havethe timeto carry
out all of his fantasies and consequently mutilation will not be
as advanced.
COMMUNIQUES ALLEGEDLYRECEIVED FROMTHE RIPPER
Another aspect of this case worth mentioning was the
comuniques allegedlyreceived fromJack theRipper. It is quite
rarewhen aserial murderer of this type communicates with
police, media,family, etc. When theydo communicate,they
generally providespecifics relative to the crime that only are
known bythe subject. ,In addition, they generallyprovide
information relative to their motivation for committing sucha
heinous crime. It is myopinion thatthis series of homicides
was notperpetrated by someone whoset up achallenge against law
enforcement. Whilethe killer knew hewould bereceiving
national as well as international publicity, this was not his '
primary motivation.
In summary,Iwould not put emphasis onthecommuniques
during this investigation. However,Iwould develop an
investigative techniquewith the goal in mind toidentify the
author of the communiques. ,
OFFENDER 'IRAITSAND CHARACTERISTICS
These homicidesare referredto as Lust Murders.Roy
Hazelwood andIwrote anarticle several yearsago whichappeared
in the FBI's LawEnforcement Bulletin.The word"lust" does nor
mean loveor have any sexualmeaning, otherthan the fact that
the subject attacks the genital areas of his victims. The
vaginalareaand breasts arethe focalpoint of attack in a woman
and the penis and scrotum are the attack area of the male
offender. Generally, males whoare attacked in this fashion are

W Qe.
I have never experienced a female serial lust murderer
either in research or in cases received at the NCAVC.It is for
this reason that Jack the Ripper was amale. He was of white
race in view of the fact that white was the predominant raceat
the crime scene locations, and generally crimes suchas these are
intraracial. . .
is
high
The age of onset for these types of homicides
generally betweenthe mid to late 20's. Basedupon the
degree ofpsychopathology exhibitedat the scene, theability of
the subject to converse with the victim until a suitable location
is found, and theability toavoid detection, placeshim between
the age bracket of 38 to 36 yearsof age. However,itshould be
noted that age is a difficult characteristic to categorize and
consequently wewould noteliminate aviable suspectexclusively
because of age. *
- This offender doesnot look out of the ordinary.
However, the clothing he wears at the time of the assaults is not
his everydaydress. He wants toproject to unsuspecting females
prostitutes! thathe has money;consequently this relieves him
from initiating contact.
He comesfrom a family where he was raised by a
domineering motherand weak,passive and/or absent father. In
all likelihood, his motherdrank heavily andenjoyed thecompany
of many men. As a result, he failed to receive consistent care
and contactwith stable adult role models. Consequently,he
became detachedsocially and developed adiminished emotional
response towardshis fellow man. Hebecame asocial,preferring
to be alone. His anger becameinternalized andin his younger
years, heexpressed hispent-up destructiveemotions bysetting
fires andtorturing smallanimals. Byperpetrating theseacts,
he discoveredincreased areasof dominance,power andcontrol,
and learned how to continue violent destructive acts without
detection or punishment.
As he grew older, his fantasy developed astrong
component that included domination, cruelty, and mutilation of
women. We would expect to find evidence of this violent
destructive fantasylife through personal writingsof his as well
as drawings of womenbeing mutilated.
For employment,he wouldseek aposition wherehe could
work aloneand vicariously experience his destructive fantasies.
such employmentwould include work as a butcher, mortician's
helper, medical examiner's assistant,or hospital attendant. He
is employedMonday throughFriday andon Fridaynight, Saturday,
and Sundayis off from work. He hascarried a knife for defense
purposes--justincase he wasever attacked,he wouldbe ready.

This paranoid-typeof thinkingis in partjustified because of
the poorself-image hehas ofhimself. Hewould beexpected to
have sometype ofphysical abnormality.However, althoughnot
severe, heperceives thisas beingpsychologically crippling.We
would lookfor someonebelow orabove averagein heightand/or
weight. Mayhave problemswith speech,scarred complexion,physical illness, or injury.
We wouldnot expectthis type of offender to be
married. Ifhe wasmarried inthe past,it wouldhave beento
someone olderthan himselfand themarriage wouldhave beenfor ashort duration. ~
He isnot adeptin meetingpeople sociallyand the
major extentof his heterosexual relationshipswould bewith
prostitutes. Dueto lackof hygienepractices byprostitutes atthat timeand theabsence oftreatment forvenereal disease,he
may havebeen infected.If infected, this wouldfurther fuelhis
hatred anddisgust forwomen. _

Jack the Ripper hunted nightly for his victims. when
he could not find another, he returned to the locations where he
killed his previous victims. If the victims wereburied locally,
he wouldvisit the gravesites ofhis victimsduring theearly
morning hoursfor the purpose of reliving his lust murders.
Jack the Ripper would not have committed suicide after
the last homicide. Generally,when crimessuch asthese cease,
it is because hecame closeto being identified, was interviewed
by police, or was arrested for some othertype of offense. As
stated previously in this report, we would besurprised if Jack
the Ripperwould suddenlystop. However,we've seenthis happen
before andgenerally it has beenbecause of the abovestated
reasons. V'
INVESTIGATIVE ANDZORPROSECUTIVE TECHNIQUES
Jack the Ripper would be best suited to be interviewed
during the early morninghours. He would feelmore relaxedand
secure to confess to the homicides. He would feel more relaxed
to expresshimself bywriting abouthis motivationfor killing
the women.He wouldnot bevisibly shakenor upsetif directly
accused ofthe homicides.However, hewould bepsychologically
andphysiologically stressed if confronted with the fact that he
became personallysoiled bythe victimsblood. Jackthe Ripperbelieved the homicides were justified and he was only removing
perishable items--whowere like garbage.
