Title: Profiling
1Profiling
2Plan for Today
- What is Profiling?
- Offender typologies
- Problems with profiling
- Geographical profiling
3What is Profiling?
- A technique for identifying the major personality
and behavioural features of an offender based on
an analysis of the crimes they have committed
4Goals of Profiling
- Suspect prioritization
- New lines of enquiry
- Interview strategies
- Predict dangerousness
- Flush out offender
5Profiling
- What do profilers do?
- provide investigators with a personality
composite, behavioral tendencies and demographic
features of the unknown offender - Also, crime and threat analysis, investigative
assistance, strategies for interviews and
prosecution, and expert testimony - Mostly homicide, also rape, arson, bombing,
espionage, stalking, extortion, kidnapping,
terrorism and product tampering - TYPES Criminal profiling, Geographical
profiling,
6Profiling
- Criminal Profile may include
- Gender, age, race, occupation, socioeconomic
status, mental status, area of residence,
educational and family background, social habits
and probable arrest history - Geographical profiling area of base
7Criminal Profiling.
- The process of inferring distinctive personality
characteristics of individuals responsible for
committing crimes has commonly been referred to
as criminal profiling
8Criminal Profiling
- A profile generalised from behavioral and
demographic characteristics shared by other
criminals. Product of statistical
characteristics and generalisation. - Ex 80 of all serial killers that attack
college students in parking lots are white males,
age 20-35, who live with their mother and drive
Volkwagen vans. - Our offender has attacked three female students
in parking lots. - Therefore our offender is a white male, age
20-35, who lives with his mother and drive a VW
van... - Assumptions
- Individual behavior and motivation can be
predicted from the study of individuals who share
similar behaviors and motivations.
9Different Types of Criminal Profiling
- Inductive Profiling
- Profiling an offender from what is known about
other offenders - Deductive profiling
- Profiling an offender from evidence relating to
the crime of that offender
10Inductive Profiling
80 of serial killers who attack people in
parking lots are white males
Our offender has attacked three people in parking
lots, therefore it is likely that our offender is
a white male
11Deductive Profiling
Body of a female victim is found with no blood or
clothing at the scene
Location is not the primary crime site due to the
lack of blood and clothing found at the scene
12The profilers dictionnary
- Modus Operandi (standard procedure)
- Behaviors committed by the offender during the
commission of the crime which are necessary to
complete the crime. - Can vary as the offender becomes more
experienced - MO ensures success, protect identity, offer
escape dynamic - Signature
- Behaviors the offender has to do to fulfill an
emotional need or a fantasy. - Thematic nature, it tends to be more stable
over time. - Needs of the offender often ritualized
- ex staging, overkill, bondage, etc.
13Example of MO and Signature
- An unknown subject rapes a woman in her home,
using a rope garrote to control her while he
rapes her, causing little or no other physical
damage. The offense takes 10 or 15 minutes and
then the offender leaves through the back door of
the residence which shows signs of forced entry. - Over the next two months, two more rapes are
committed by the same rapist with roughly the
same MO, each taking about ten to fifteen
minutes. Investigators are able to make the
connections right away because of DNA evidence
collected at the various scenes. During rape
number three, it is noted, the victim struggled a
great deal and very heavy ligature furrows are
observed on her neck. - A week later, a fourth victim emerges. The fourth
victim explains in her statement how the offender
brought her in and out of consciousness
intentionally using a rope garrote, and how the
offender spent almost an hour with her. DNA
evidence is unavailable for this fourth rape is
victim number four related?
14Example of MO and Signature
- All else being equal, this is the same offender.
- What has occurred is that the offender, over
time, has eroticized the use of the garrote.
During the first rapes, the garrote was a means
to acquire and maintain control of the victim (MO
Oriented). - Over time and experience, the offender developed
a sexual desire to strangle his victims while
raping them (Fantasy Oriented). - This is not surprising given the strong
association of the garrote with the act of rape
during the first few attacks. - The presence of an object or behavior during sex
can quite easily lead to it's eroticization and
inclusion in fantasy and subsequently fantasy
behavior.
15How do you create a Profile?
- Behavior reflects personality!
- Actions before, during and after crime
- Look at what offender chose to do and what he
chose not to do. (Behavioral fingerprint) - Signature
- What did he do that he did not have to?
16How do you create a Profile?
- Look at evidence, police and autopsy reports,
crime scene photos, i.e., learn everything about
the offender - Use inductive and deductive reasoning, experience
of violent behavior, facts of particular case,
and statistical probabilities. - In depth interviews with violent offenders

19THE ORGANIZED/DISORGANIZED OFFENDER
- The organized/disorganized offender is an FBI
model. The organized/disorganized offender
dichotomy has a strong crime scene focus. - Stage 1 Collecting inputs, which are essential
for accurate profiling - State 2 Using Decision Process Models, which is
the process of organizing and arranging the
inputs into meaning patterns - Stage 3 making the crime assessment, which is
the reconstruction of the sequence of events and
the behavior of both the victim and the offender
20THE ORGANIZED/DISORGANIZED OFFENDER
- Stage 4 Developing the criminal profile, a
process which addresses the type of person who
committed the crime and that individual's
behavioral organization in relation to the crime,
including background information, physical
characteristics, habits, beliefs, values,
pre-offense behavior leading to the crime and
post-offense behavior
21THE ORGANIZED/DISORGANIZED OFFENDER
- Stage 5 Continuing the on-going investigation by
those assigned to it, with the profiler making
adjustments in the profile if fresh information
warrants it and being available to discuss the
case with those assigned on an as-needed basis - Stage 6 Following the apprehension, reviewing
the agreement between the outcome and the various
stages of the profiling process are examined
22Organized, Disorganized, Mixed typology
23Organized crime scene predicts
- Premeditation, manipulative, cunning, deliberate
and methodical. Psychopathic (narcissistic and
remorseless) - Pride in appearance, articulate, outgoing,
charming - Crimes and aftermath well planned and executed
- Chooses targets carefully, brings own weapon,
tries to conceal the body - CONTROL (a thinking criminal)
- Older, more mature, leave general area (drive)
24Disorganized Crime Scene predicts
- Loner, few social skills and ties, feels
inadequate - Sloppy unkempt appearance (home), haphazard
impulse crimes against victims of opportunity. - More likely to attack family, friends, neighbors
or acquaintances - Frenzied crime scene sparked by drugs, mental
illness, or inexperience. Mutilation and overkill
- Symbols of disorganization reflect delusions
- Blitz attack, leaving victim
- Attack close to home, walk or public
transportation
25Mixed crime scene
- Young offender making transition to organized
predator - Short temper but plans revenge without taking
unnecessary risks - Situational factors (inability to control victim)
leading to improvised behavior - More than one perpetrator
26The profilers dictionnary (cond)
- Serial murder, Spree murder, and Mass murder
- Serial three or more separate events with a
cooling off period between homicides) - Spree killing at 2 or more locations with no
emotional cooling off period between homicides. - Mass anything more than 3 victims in one
location and within one event. -
27Homicidal trends
- Serial killers
- generally target strangers, consistency in victim
profile - Cooling off period
- Trophies
- At least 3 victims
28THE HOLMES TYPOLOGY
- ACT-FOCUSED (quick kill)
- 1 - THE VISIONARY - hears voices or sees visions
that tell him to kill (psychotic), the voices
tend to be either God or the devil, legitimating
the violence. - 2- THE MISSIONARY - goes on hunting "missions" to
eradicate a group of people (prostitutes, Jews,
etc.) from face of earth, seems like "fine young
man" to neighbors. - PROCESS-FOCUSED (slow kill)
- 3 - THE COMFORT-ORIENTED HEDONIST - takes
pleasure from killing, but also gets some profit
or personal gain from it. (mostly women) - 4 - THE LUST-ORIENTED HEDONIST - associates
sexual pleasure with murder, sex while killing
and necrophilia are eroticized experiences. - 5 - THE THRILL-ORIENTED HEDONIST - gets a "rush"
or "high" from killing, an elixir of thrills,
excitement, and euphoria at victim's final
anguish. - 6 - THE POWER/CONTROL FREAK - takes pleasure from
manipulation and domination (sociopath),
experiences a "rush" or "high" from victim's
misery.

40Criticisms of Profiling
41Criticisms
- Despite its successes, profiling as a field is
not without criticisms. Include in these
criticisms are - untrained or inadequately trained profilers
- promising too much and delivering too little
- relying on inadequate or dated databases
- overstating the meaning of physical evidence
42Problems with profiling
- Can only create imprecise stereotypes,
descriptions are vague and general - There is little theoretical foundation for
generated demographic and personality factors - Can narrow the investigation parameters
- Art based on experience rather than science
43A Cheaper Alternative?
44What is Geographic Profiling?
- Geographic profiling is a technique typically
used in serial violent crime investigations. It
involves an analysis of crime scene locations in
order to determine the most probable area of
offender residence.
45What is Geographic Profiling?
- Geoprofiling/GP is an investigative strategy that
uses the locations of a series of crimes to
determine the most probable area of the offenders
residence - GP does not solve crimes it does prioritize
suspects and their likely addresses - This allows investigators to focus their
resources and strategies, e.g., saturation
patrol, surveillance, and neighborhood canvasses
46Where Does a Geographic Profile Fit?
- Occurrence of a crimes series
- Use of traditional investigative techniques
- Linkage analysis
- Criminal profile
- Geographic profile
- New investigative strategies
471. Awareness and Activity Spaces
AWARENESS SPACE
ACTIVITY SPACE
482. Importance of the Home
493. Buffer Zone
- An area surrounding the criminals home where
targets are viewed as less desirable (and
therefore crimes are less likely).
