Introduction toForensic Psychology2nd
EditionBartol Bartol (2008)
  • Chapter 3
  • Police Psychology
  • Investigative Psychology

Investigative Psychology
  • DEFINITION The application of psychology to
    criminal investigation.
  • Profilingone of the tasks often associated with
    investigative psychologyrequires sketching the
    significant psychological and demographic
    features of a person or persons.
  • Broadly defined, investigative psychology
    includes research and practice involving
  • -Profiling -Risk Assessment
  • -Police Line-ups -Interrogation
  • -Polygraph Hypnosis -Other?
  • -

3 Questions
  • What are the important behavioral features of the
    crime that may help identify and successfully
    prosecute the perpetrator?
  • What inferences can be made about the
    characteristics of the offender that may help
    identify him or her?
  • Are there any other crimes that are likely to
    have been committed by the same person?

4
CRIMINAL PROFILING Background
5
What is Criminal Profiling?
  • Criminal profiling is the process of identifying
    personality traits, behavioral tendencies,
    geographical location, and demographic or
    biographical descriptors of an offender (or
    offenders) based on crime scene characteristics.

6
Goals of Profiling
  • The primary goal of profiling is to narrow the
    field of possible suspects.
  • Profiling is also a form of prediction -- the
    profiler tries to predict who the offender or
    offenders might be and where and how the next
    crime may occur.

7
Why Use Criminal Profiles in Law Enforcement?
  • Traditional investigative techniques often fall
    short in extreme cases.
  • A subset of offenses/offenders are considered
    most suitable for profiling -- What subset of
    offenders and why more suitable for profiling??

8
Brief History of Criminal Profiling
  • 1940s - First recorded use by psychiatrist Walter
    Langer during WWII commissioned to construct a
    psychodynamic profile of Hitler.
  • 1957 - psychiatrist James Brussels worked with
    NYPD to construct a profile of the Mad Bomber.
  • 1970s-1980s - FBI (Howard Teten, John Douglas,
    Robert Ressler, Roy Hazelwood, and others) became
    involved in psychological profiling and
    popularized the technique.
  • 1990s 2003 - attempt (by David Canter, Maurice
    Godwin, Ron Holmes, Robert Keppel, Brent Turvey,
    Kim Rossmo and others) to scientize profiling and
    move the practice beyond the purview of the FBI.

9
The FBI Profilers
  • Small/prominent group of FBI profilers helped to
    popularize the term in 1970s in the Behavioral
    Science Unit -- called the National Center for
    the Analysis of Violent Crime (NCAVC) since 1984.
  • Responsible for establishing the Violent Criminal
    Apprehension Program (VICAP). Published Crime
    Classification Manual, Sexual Homicide Patterns
    and Motives and true crime novels.
  • Are known for the ORGANIZED/DISORGANIZED typology
    and focus on M.O. and SIGNATURE.
  • Criticized for relying too much on
    intuition/faulty use of the scientific method.

10
Is Profiling a Science or Profession?
  • Profiling has not yet achieved the status of a
    profession. Factors hindering professionalization
  • Lack of consensus (on terms, approaches,
    training, appropriate experience/educational
    background, etc.).
  • Practical issues (sensitivity and confidentiality
    of cases).
  • Ego/territorial issues.
  • Absence of uniform standards, practices, peer
    review, and ethics.
  • Small number (if any) of profiling positions
    where profiling is the primary job description.
  • The notion (and acknowledgement among many
    profilers) that profiling is more art
    than science.

11
Assumptions Made in the Profiling ProcessSee
Holmes Holmes (2001). Profiling Violent Crimes.
Sage.
  • Crime scene reflects the personality of the
    offender.
  • M.O. remains similar.
  • Signature will remain the same.
  • Offenders personality will not change.

12
The Organized-Disorganized Typology
  • Whether or not the crime scene is left ORGANIZED
    or DISORGANIZED is said to provide information
    about the offenders criminal sophistication and
    personality.
  • Organized crime scene reflects offender who
    commits crime out of a need for power. Motivation
    associated with PSYCHOPATHY.
  • Disorganized crime scene reflects offender who
    commits crime out of passion, compulsion,
    frustration, or anxiety. Motivation associated
    with PSYCHOSIS.

13
The Organized Crime Scene See Ressler, Burgess,
Douglas (1992) Sexual Homicide Patterns and
Motives. Free Press.
  • Offense planned
  • Victim a targeted stranger
  • Victim personalized
  • Controlled conversation
  • Crime scene reflects overall control
  • Demands submissive victim
  • Restraints used
  • Aggressive acts prior to death
  • Body hidden
  • Weapon/evidence absent
  • victim or body transported from scene
  • Associated with psychopathy

14
The Disorganized Crime Scene See Ressler,
Burgess, Douglas (1992) Sexual Homicide
Patterns and Motives.
  • Spontaneous offense
  • Victim or location known
  • Depersonalizes victim
  • Minimal conversation
  • Crime scene random and sloppy
  • Sudden violence to victim
  • Minimal use of restraints
  • Sexual acts after death
  • Body left in view
  • Evidence/weapon often present
  • Body left at death scene
  • Associated with Psychosis

15
Interview/Interrogation StrategiesSee Holmes
Holmes (1996) Profiling Violent Crimes. Sage.
  • ORGANIZED
  • Direct confrontation
  • Respects competency
  • One-person interview
  • Dont expect free information
  • No use of false evidence (are too sharp for
    this)
  • Conduct when suspect has no time to gather
    thoughts
  • DISORGANIZED
  • Relationship motivated
  • Empathy
  • Constant stream of conversation
  • Use positive personal relationship
  • Conduct at night

16
Distinction Between Psychopathy and Psychosis
  • PSYCHOPATHY
  • Personality disorder made up of a particular
    constellation of characteristics)
  • Lack of attachment, defect in affect, absence of
    anxiety
  • In touch with reality
  • PSYCHOSIS
  • Clinical mental illness Schizophrenia
  • May meet legal definition of insanity
  • Out of touch with reality

17
Criticism of the Organized/Disorganized
Typology See Turvey (2002) Criminal Profiling.
Academic Press.
  • Developed/oversimplified for use by law
    enforcement professionals with little academic
    training in criminology, psychology, and forensic
    science and encourages unsophisticated profiling.
  • Is a FALSE DICHOTOMY --few offenders/crime scenes
    it neatly into either type.
  • Other problems?

18
M.O. and Signature(See Douglas, Burgess,
Burgess, Ressler (1997). Crime Classification
Manual. Jossey-Bass Keppel, R.D. Birnes, W.J.
(1997). Signature Killers. Pocket Books.
  • METHOD OF OPERATION (M.O.)
  • How the offender committed the crime. Tells about
    the experience of the offender and
    situational/contextual factors involved in the
    crime.
  • SIGNATURE
  • The behavior/expression of fantasy the killer
    must leave at the scene to satisfy
    emotional/psychological needs. Goes beyond whats
    necessary to commit crime and tells about the
    offenders psychological needs and motivation.

19
Factors that Shape M.O.
  • Trade/Professional Experience
  • Criminal experience and confidence
  • Contact with the criminal justice system
  • Media and pop culture
  • Offender Mood/Mental state
  • X-Factors (unknown/unplanned influences)

20
Factors that Shape Signature
  • Personality/Psychopathology
  • Evolution of Fantasy

21
Distinguishing M.O. from SignatureSee Turvey
(2002) Criminal Profiling. Academic Press.
  • Signature and M.O. needs may be satisfied by the
    same behavior. Important to remember the two
    most important axioms of criminal profiling
  • Different offenders do similar things for
    different reasons.
  • Offender behaviors can be the result of multiple
    motivations and/or external influences.

22
Static and Dynamic RiskSee Andrews Bonta
(2003). The Psychology of Criminal Conduct.
Anderson.
  • Offender risk factors are static and dynamic. Are
    important in understanding M.O. and Signature
    behaviors.
  • STATIC RISK Stay the same over time
  • DYNAMIC RISK Change over time
  • Stable dynamic change slowly over months or
    years
  • Acute dynamic change rapidly over minutes or
    days.
  • What type of risk factors are M.O. and Signature
    behaviors?

23
The Psychological Autopsy
  • The Psychological Autopsy is an attempt to
    reconstruct the personality profile and cognitive
    features of deceased. This postmortem
    psychological analysis is also called
    reconstructive psychological evaluation and
    equivocal death analysis . Psychological
    autopsies are important to
  • Assist certifying officials to clarify deaths
    that are ambiguous, uncertain, or equivocal as to
    the manner of death
  • Aid in investigation to determine insurance
    payments and national security issues.
  • To make a reasonable determination of what may
    have been in the mind of the deceased person
    leading up to and at the time of
    deathparticularly if the death appears to be a
    suicide
  • Psychological autopsies differ from criminal
    profiling in two important ways (1) the profile
    is constructed on a dead person, and (2) the
    identity of the person is already known.

24
Geographical Profiling and Mapping
  • Geographical profiling refers to the analysis of
    geographical locations associated with the
    spatial movements of a single serial offender,
  • Geographical mapping is concerned with analyzing
    the spatial patterns of crimes committed by
    numerous offenders over a period of time.
    Geographical mapping focuses on identifying the
    hot spots of certain types of crime.
  • In 1995, D. Kim Rossmo wrote a doctoral
    dissertation at Simon Frasier Universitys School
    of Criminology on geographical profiling. Rossmo
    developed a computer program called Criminal
    Geographic Targeting (CGT). It is designed to
    analyze the geographical or spatial
    characteristics of an offenders crimes.

25
The Polygraph
  • The polygraphcommonly called the lie
    detectordetects psychophysiological responses
    that accompany emotional reactions to guilt,
    shame, and anxiety through heart rate, blood
    pressure, breathing rate, and skin conductance.
  • In addition to observing the physiological
    measures, the skillful polygrapher makes
    behavioral observations and notations to infer
    truth or deception in the subject being examined.
  • The polygraph can accurately measure and record
    the physiological responses but it is unclear
    whether it can detect actual lying and deception.

26
INVESTIGATIVE PSYCHOLOGY AND OFFENDER
PROFILING Discussion Questions
27
Discussion Questions(Homant Kennedy/BB Supp
Readings)
  • What are the major limitations in researching the
    effectiveness of profiling?
  • Why Is Profiling So Inaccurate?
  • What direction do the authors of your readings
    this week (e.g., Homant Kennedy) suggest we
    need to go in terms of conducting research on
    profiling? How do Homant Kennedy define
  • Offender Profiling
  • Psychological Profiling
  • Geographical Profiling
  • Equivocal Death Analysis

28
Discussion Questions(Muller/BB Supp Readings)
  • What two main approaches to profiling are
    reviewed in this article? Explain the features of
    each.

29
Discussion Questions(BB Text Ch 3)
  • What might explain the popularity of profiling,
    despite the lack of evidence to support it?
  • What other applications of psychological theory
    and research do the authors suggest can be
    considered under the heading of investigative
    psychology?

30
Discussion Questions General(BB (Text)
  • Explain the significance of static and dynamic
    risk factors in the prediction and profiling of
    human behavior.
  • Explain how the processes of a) unconscious
    transference and b) own-race bias can affect
    identification provided by eyewitnesses to an
    event.
  • Forensic psychologists have offered
    recommendations to police in constructing
    line-ups. What are these recommendations? Upon
    what research findings are they based?
