Title: Offender Profiling


1
Offender Profiling
  • Gareth Norris
  • 1st March, 2005.

2
A Brief History
  • Thomas Bond and Jack the Ripper
  • Walter Langer and Adolf Hitler
  • James Brussel and the Mad Bomber
  • Howard Teten and Pat Mullany
  • John Douglas and Robert Ressler
  • David Canter

3
Whitechapel London 1888
  • Dr Thomas Bond Forensic Pathologist
  • Believed the offender to be suffering from
    Satyriasis excessive and uncontrollable sexual
    desire in males
  • Believed the offender may also be a surgeon or
    medical practitioner due to the skill in which he
    dissected his victims
  • The case of the Dusseldorf Vampire, Peter Kurten,
    also included a number of psychological
    considerations by the pathologist Dr Karl Berg in
    1929, believing him to be a narcissistic
    psychopath

4
Office of Strategic Services 1943
  • Psychiatrist Walter Langer commissioned by US OSS
    to provide a psychological profile of Adolf
    Hitler
  • Provided various detailed descriptions of Hitler
    and how he saw himself, how he was regarded by
    his colleagues and also how the German people
    viewed him
  • Believed him to be overwhelmed by his Oedipal
    complex, in dire need to express his manliness to
    his mother, and that at the ultimate climax to
    conflict would commit suicide
  • Freud and Bullit Woodrow Wilson 1934 (1964)

5
New York 1956
  • Psychiatrist James Brussel asked to profile Mad
    Bomber
  • Believed offender would be middle-aged,
    unmarried, well educated and live alone or with a
    mother-like figure
  • Also stated he would be wearing a
    double-breasted suit buttoned
  • Later profiled Albert DeSalvo The Boston
    Strangler

6
Quantico, Virginia 1972-
  • FBI special agents Howard Teten and Pat Mullany
  • Collaborated with Brussels in systemizing this
    emerging field
  • Began teaching abnormal psychology and applied
    criminology to students at the academy
  • Behavioural Science Unit (BSU)

7
Still in Quantico
  • In 1979, the BSU began the Criminal Personality
    Research Project (CPRP)
  • Eventual data collection took some 4 years
    (1979-1983) and involved by its completion, some
    29 individuals, including a number of
    professional staff from the Boston City Hospital
  • Interviews conducted with 36 incarcerated sexual
    killers NOT all serial killers
  • Chapter - Crime Scene and Profile Characteristics
    of Organized and Disorganized Murderers

8
Organised and Disorganized
  • Refers to the appearance of the crime scene
  • Each is classified and then the offenders likely
    characteristics are ascertained
  • Incorporates investigator experience and
    intuition
  • Also a mixed category

9
Organised and Disorganised Crime Scenes
  • Offence planned
  • Victim is a stranger
  • Personalizes victim
  • Controlled conversation
  • Overall control
  • Submissive victim
  • Restraints used
  • Aggressive acts
  • Body hidden
  • Weapon/evidence absent
  • Transports body
  • Spontaneous offence
  • Victim or location known
  • Depersonalizes victim
  • Random and sloppy
  • Sudden violence
  • Minimal use of restraints
  • Sexual acts after death
  • Body left in view
  • Weapon/evidence present
  • Body left at death scene

10

11
Surrey, England 1985
  • New Scotland Yard consult psychologist David
    Canter about profiling
  • 1986 Canter provides profile of John Duffy -
    The Railway Rapist
  • Profile is remarkably accurate and Duffy is
    sentenced to life imprisonment apprehended
    partly through Canters advice
  • MSc in Investigative Psychology begins at Surrey
    University (moves to Liverpool University in 1994)

12
Narrative Theory Five Factor model
  • Narrative theory is based on the way in which we
    live our lives according to scripts which help
    us to make sense of the world
  • Our inner-narratives dictate the way in which we
    deal with people and situations, in both criminal
    and non-criminal interactions.
  • Considerable overlap between the two
  • Five factors of behaviour between offender and
    victim interpersonal coherence, significance of
    time and place, criminal characteristics,
    criminal career, and forensic awareness

13
SSA of crime scene actions -Interpretation
  • Core High Frequency
  • Behaviours
  • Victims face not hidden (88)
  • Victim at scene where killed (79)
  • Victim found where fell (61)
  • Multiple wounds (52)

Instrumental
Covered
Naked
Manual
Bound
Sexual
Transported
Shot
Expressive
Drugged/Poisoned
14
IP, the FBI and statistics
  • Both use statistics to generalise from past
    behaviours
  • FBI developed organised/disorganised hypothesis
    using analysis of interviews with incarcerated
    serial killers
  • FBIs typology (although groundbreaking) is
    essentially flawed, both theoretically and
    methodologically
  • IP used more rigorous and sophisticated analysis
    and makes findings available for peer review

15
Fundamental Concepts and Terms
  • Profiling thought
  • Crime scene characteristics
  • Method of approach and attack
  • Motive, MO and Signature
  • Victimology

16
Profiling Thought
  • A great deal of profiling is about the way we
    think
  • Most offender behaviour is rational and logical
    (even the seemingly bizarre) and so too should
    our thoughts as profilers be rational and logical
  • Mysticism has little place in the profiling
    process
  • Understanding ones level of competence not
    walking in the shoes of the murderer
  • Most of all, our conclusions should be backed up
    by evidence and sound reasoning

17
Crime Scene Characteristics
  • Determining where a crime occurred in relation to
    other crime scenes is vital for reconstruction
    purposes
  • If we have a secondary scene, then we know we
    have to find a primary scene where large amounts
    of evidence may be
  • An offenders choice of crime scene may tell you a
    lot about the offenders motive, familiarity with
    a location or victim choice

18
Continued
  • Point of contact
  • Primary crime scene
  • Secondary crime scene
  • Intermediate scene
  • Dump/disposal site

19
Motive, MO and Signature
  • Motive and MO have traditionally been used for
    case linkage
  • These are the two most problematic ways to link a
    case
  • Motive is extremely broad and applies to groups
    of offenders as well as individuals
  • MO also refers to the behaviour of groups, but is
    extremely dynamic across offences
  • Signature is perhaps the best option for case
    linkage

20
Continued
  • Motive
  • Refers to the motivation of the offender for
    committing the crime
  • There is always a motive for a crime, though it
    may not be readily apparent
  • No one acts without motivation (Geberth, 1996)
  • MO
  • Modus operandi or method of operation
  • Refers to those things the offender did that were
    necessary for the successful completion of the
    crime
  • May refer behaviours at the crime scene, with the
    victim, or self
  • Functional in nature

21
Continued
  • Signature
  • Reflects the underlying psychological or physical
    needs of the offender
  • Therefore, is not a functional aspect of the
    offence
  • Refers to those things that the offender did at
    the crime scene, or to the victim, that were not
    necessary for the successful completion of the
    crime

22
Victimology
  • A thorough and comprehensive examination of the
    background of the victim
  • Includes all aspects of the victims life
  • Height, weight, education, sexual history, drug
    use, clothing, time line
  • You may discover things about the victim that
    close friends and family did not know
  • Connections between the victim and third parties
    may offer insight into victim choice, where the
    victim was encountered, places to search for
    evidence

23
Profiling Inputs FBI
  • Crime Scene
  • Evidence, body position, weapons
  • Victimology
  • Background, habits, family, last seen, age,
    occupation
  • Forensic Information
  • Cause of death, wounds, autopsy, sexual acts
  • Preliminary Police Reports
  • Background info, police observation, time of
    crime, crime rate of neighbourhood
  • Photos
  • Aerial, crime scene, victim

24
What does a profile look like?
  • Depends on who is constructing it
  • Usually contains material relating to the
    background and characteristics of the offender,
    e.g. age, gender, education, intelligence,
    employment, residence etc.
  • Sometimes includes interview strategies and
    post-offence behaviour
  • May also include intuitive considerations
  • No specified or universal format
