Title: Criminal Personality Profiling


1
Chapter 31
  • Criminal Personality Profiling

2
Criminal Personality Profiling
  • Purpose of offender profiling is to help
    investigators to narrow the field of suspects
    based on the characteristics of the crime scene
    and initial investigative information

3
Criminal Personality Profiling
  • FBI Behavioral Sciences Unit has developed an
    accepted investigative tool for officers tasked
    with solving violent crimes by understanding
    certain aspects of violent criminal behavior

4
Criminal Personality Profiling
  • Policing today is performed by professionals
    possessing better education and training
  • These individuals use advancements in forensic
    science and investigations to their advantage to
    assist in solving crime

5
Criminal Personality Profiling
  • Profiling process provides an approach to conduct
    a thorough and competent behaviorally based
    examination of crime scenes and investigations of
    violent crimes that display characteristics
    amenable to profiling process
  • Behavioral evidence at crime scenes may give
    insight into characteristics of offender

6
Expert Test
  • Experts should meet following criteria
  • Has expert had opportunity to review
    criminological research at FBI BSU, academicians
    or other law enforcement researchers

7
Expert Test
  • Has expert been trained extensively in
    theoretical and behavioral aspects of criminal
    behavior, crime scene reconstruction,
    criminalistics and other forensic fields

8
Expert Test
  • Does expert have extensive investigative
    experience involving violent crimes, hands on
    processing of crime scenes, examining effects of
    wounding and injuries, observing autopsies, and
    applying criminal analysis to wide range of
    violent crimes

9
Expert Test
  • Does the expert approach the investigation of
    an unsolved violent crime from a law enforcement
    perspective rather than a clinical psychology one?

10
History of Profiling and Criminal Investigative
Analysis
  • Sherlock Holmes and Charlie Chan brought common
    place crime solving skills into play
  • Experienced investigators of violent crime
    develop a cumulative sense of offender traits

11
History of Profiling and Criminal Investigative
Analysis
  • During the 1950s and 1960s, a select cadre of
    sworn law enforcement officers was selected to
    attend FBI Academy
  • As new techniques were developed, ideas were
    shared which would promulgate cooperative crime
    solving methods

12
History of Profiling and Criminal Investigative
Analysis
  • FBI developed Behavioral Science Unit
  • Development of quantitative and qualitative
    research was done
  • Face to face interviews with convicted offenders
    were done to better understand criminal behavior
    and conduct

13
Criminal Investigative Analysis
  • Processes of criminal investigative analysis are
  • Crime from a behavioral perspective
  • Criminal personality profiling
  • Crime scene analysis and reconstruction
  • Search warrant applications

14
Criminal Investigative Analysis
  • Investigative strategies
  • Interview and interrogation strategies
  • Prosecution strategies
  • Case linkage of serial offenses
  • Equivocal death analyses
  • Threat analyses

15
General Concepts
  • National Center for the Analysis of Behavioral
    Crime is operational successor of FBIs
    Behavioral Science Unit
  • CIA collection and processes have been very
    successful in assisting in the apprehension of
    criminals

16
Profiling
  • Profiling is defined as the identification of
    certain characteristics of an unknown,
    unidentified offender based on the way he
    committed a violent act, and his interactions
    with the victim

17
Descriptive Traits of Offender
  • Some traits are learned from witnesses, but most
    valuable are from combination of
  • Crime scene examination
  • Investigative experience
  • continued

18
Descriptive Traits of Offender
  • Understanding of offender and victim behaviors
  • Knowledge of wound patterns
  • Knowledge of forensic evidence
  • Results of research conducted by FBI/BSU

19
Categories of Profiling Descriptors
  • Categories include
  • Sex
  • Race
  • Age
  • Criminal History

20
Categories of Profiling Descriptors
  • Employment History
  • Social Adjustment
  • Sexual adjustment or abnormalities
  • Alcohol or drug usage
  • Educational level
  • Interpersonal skills

21
Victimology
  • Victimology victims history that impacts the
    analysis of a crime and the behavioral study of
    a victim of a violent crime

22
Victimology
  • Victimology examines areas including victims
    reputation, lifestyle, habits, associates, and
    pastimes to form an opinion about individuals
    risk of becoming a crime victim

23
Victimology
  • Goal of victimology in investigation is to answer
    critical questions
  • Why was that person attacked instead of another
    person?
  • Was the victims lifestyle a contributing factor
    toward victimization?

24
Victimology
  • By learning the personality, attitudes,
    lifestyle habits and perspectives of a victim,
    the crime scene and offense can be better
    analyzed and evaluated for a better behavioral
    understanding of what transpired and why crime
    occurred.

25
Trophy or Souvenir- What is Taken from Victim?
  • Difference in offenders is demonstrated by items
    taken from victim and categorization of those
    items
  • Evidentiary
  • Valuables
  • Psychological

26
Trophy or Souvenir- What is Taken from Victim?
  • Depending on the perspective of the criminal,
    items taken from victims may represent trophies
    or souvenirs

27
Trophy
  • Is the item significant to the offender as an
    accomplishment or a victory and is a trophy of
    his action

28
Souvenir
  • Is the item taken a fondly remembered
    occurrence and retained as a souvenir for
    conclusion in masturbatory fantasies

29
Three Axioms for Offender Profiling
  • 1. Behavior reflects personality
  • How a person acts helps to determine their
    personality.

30
Three Axioms for Offender Profiling
  • 2. Behavior left at a crime scene can be
  • discerned
  • Evidence left at crime, such as DNA, prints,
    hair, blood, threads from clothing, leaves behind
    traces of behavior

31
Three Axioms for Offender Profiling
  • 3. Cumulative research into human behavior by the
    FBI and many others has allowed behavioralists to
    classify offenders into typologies

32
Analysis of the Three Axioms
  • To offer and analysis, investigators must
  • Base analysis on concrete data
  • Not venture forth and offer an opinion before a
    conclusive observation of all evidence is
    reviewed
  • Not use flawed or inaccurate data in
    determination of final analysis

33
Results Type of Analysis
  • Crime Analysis- Investigator gathers all
    available data about commission of criminal act,
    the victim and offender
  • Each act or behavior at a crime scene is examined
    by asking why and how event occurred

34
Results Crime Analysis
  • What type f person would have acted in that
    manner?
  • Crime analysis generally allows investigator to
    reconstruct interaction between offender ad the
    victim, and permits explanation of individual
    pieces of crime scene puzzle

35
Results Crime Analysis
  • Process of crime scene analysis allows for a
    better understanding of offenders motivation,
    criminal sophistication, and possible prior
    relationship with victim

36
Results Crime Analysis
  • As new evidence arrives during crime analysis,
    investigator may rethink his analysis, and adjust
    his interview and investigative strategies
  • Logical thinking and specific parameters should
    be used by investigators

37
Results Crime Analysis
  • Examples of bodies of knowledge necessary for
    successful investigator
  • Knowledge and limitations of scientific
    techniques
  • Understanding of criminal thinking practically
    and academically
  • Special expertise of criminal investigators

38
Crime Scene Reconstruction
  • Crime scene reconstruction allows crime scene
    investigator to understand how victim was
    approached and controlled, and interactions
    between victim and offender

39
Crime Scene Reconstruction
  • Critical part of crime analysis is to be able
    to reconstruct and sequence criminal acts as they
    occurred in interaction between victim and
    offender

40
Crime Scene Reconstruction
  • Assists investigator in getting a better feel for
    the crime how and why crime occurred
  • Level of spontaneity or planning of crime by
    offender may be ascertained
  • Allows investigator to have a broader foundation
    of knowledge to conduct investigation

41
Investigative and Prosecutorial Strategies
  • Strategizing over investigation of crime is part
    of investigators approach
  • Avenues for exploration and psychological
    strengths or weaknesses of individuals may be
    part of investigative strategy

42
Investigative and Prosecutorial Strategies
  • Preparation of inclusive or partial media
    statements can assist in framing vulnerabilities
    of suspect and allow for insider information to
    be withheld

43
Investigative and Prosecutorial Strategies
  • Prosecutors may use knowledge of offender
    behavior and motivation to
  • Arrange proof offered in a specific manner
  • Structure questions specifically
  • Order questions specifically

44
Investigative and Prosecutorial Strategies
  • Prosecutor strategy continued
  • Include trigger terminology of special
    significance to defendant
  • Use inside information to tie together themes in
    prosecution strategy and include information in
    arguments

45
Interview and Interrogation Strategies
  • Case resolution often rests with results of
    investigators interview and interrogation skills

46
Interview and Interrogation Strategies
  • Two prongs of offender specific interview and
    interrogation strategies
  • Behavioral evidence from crime scene
  • Specific background and behavioral traits of
    suspect

47
Interview and Interrogation Strategies
  • Prong one involves behavioral evidence
    retrieved from crime scene
  • Evidence reveals information about offenders
    criminal makeup- motivation, skill, victim
    selection process, interpersonal skills, anger
    control, criminal sophistication, and personal
    elements

48
Interview and Interrogation Strategies
  • Prong two involves the specific background and
    behavioral traits of a suspect
  • Valuable source of information about suspect can
    be retrieved from police officers who had prior
    contact with suspect

49
Interview and Interrogation Strategies
  • Prong two continued
  • Suspects have favorite mechanisms they use
    without conscious thought to protect their self
    concept
  • These are developed and honed over years
  • Deeply ingrained within their personality and
    have become second nature

50
Interview and Interrogation Strategies
  • Prong two continued
  • Criminals rely on three ego-defense mechanisms
    called RPMs
  • R- Rationalization
  • P- Projection
  • M- Minimization

51
Interview and Interrogation Strategies
  • Through a combination of these RPM mechanisms,
    a suspect changes objective reality to a
    personalized view, and saves face and feels
    better about his action(s)

52
Interview and Interrogation Strategies
  • One of the principle goals of the investigator is
    to tap into suspects protective mental process
  • Investigator gives impression he understands
    suspects criminal behavior
  • Allows criminal to believe his actions are
    understandable

53
Case Linkages for Serial Offenses
  • MO has three general purposes for the criminal
  • Enable completion of criminal act
  • Prevent offenders identification
  • Ease escape of criminal
  • MO may be all information investigator has
    available to use for investigation

54
Case Linkages for Serial Offenses
  • More reliable method for case linkage is
    recognition of aspects within a crime that go
    beyond elements of MO. These may include
  • Psychological drives of criminals and
    particularly psychosexual drives of sex offenders
  • Repeated behavior of suspect at scenes
  • Unique behavior of suspect at scene

55
Equivocal Death Analyses
  • Equivocal death involves knowing cause of death
    but not accurate manner of death
  • Data is placed into one of eight columns which
    address factors consistent or inconsistent with
    types of death

56
Equivocal Death Analyses
  • Crime scene indicators coupled with victimology
    and other data from initial investigations are
    used to provide clear and compelling evidence for
    determining the proper manner of death

57
Equivocal Death Analyses
  • Eight investigative findings to be evaluated
  • Factors consistent with homicide
  • Factors inconsistent with homicide
  • Factors consistent with suicide
  • Factors inconsistent with suicide

58
Equivocal Death Analyses
  • Eight investigative findings to be evaluated,
    continued
  • Factors consistent with accidental death
  • Factors inconsistent with accidental death
  • Factors consistent with natural causes
  • Factors inconsistent with natural causes

59
Equivocal Death Analyses
  • Goal is to arrive at a preponderance of the
    factors listed under one heading
  • A systematic and thorough review of all evidence
    should lead to an investigative conclusion as to
    the manner of death

60
Search Warrant Application
  • CIA may be used in search warrant applications
  • Description of what occurred during commission of
    crime and what behavior reveals about suspect can
    be correlated to suspect
  • Additional information such as criminal acts, or
    past criminal activities can be tied to current
    activities of suspect

61
Concepts and Applications in Sexual Assault
Investigations
  • Victim risk includes subjectively classifying
    victims according to their vulnerability to
    violent crime based on their everyday lifestyles

62
Concepts and Applications in Sexual Assault
Investigations
  • Victim risk classifications are
  • High risk
  • Moderate risk
  • Low risk

63
Offender Risk Assessment
  • Factors to consider for offender risk assessment
    are
  • Risk assessment of victim
  • Concern or lack of concern of offender being
    caught due to factors such as time of day,
    witness potential, identity concealment, presence
    of alarms or security cameras

64
Victim Selection
  • Psychological process of selecting victims range
    from simple to complex
  • Victim selection may be based on
  • Associational level with offender
  • Idealized typing of victim by offender
  • Availability of victim
  • Established rules for victims by suspect
  • Ability of suspect to control victim

65
Offender Typologies
  • Roy Hazelwood was one of premier designers of CIA
    process
  • Designed typologies for six categories of rapists
  • Categories included manipulation of power,
    expression of anger, with subdivisions within
    each category

66
Offender Typologies
  • Additional categories included rapists who raped
    incidental to another crime, and lonely heart
    rapists looking for sexual arousal
  • Hazelwood also offered typologies in
    relationships between victim and offender,
    offenders residency in relationship to victim,
    prior criminal offending, offenders age and
    race, etc

67
False Allegations
  • False allegation is defined as an unfounded
    claim of having been sexually assaulted , or
    having received threatening or obscene notes or
    telephone calls

68
False Allegations
  • Impact of false allegation is twofold
  • Investigative resources are spread thin by
    investigation of false allegations
  • Legitimate victims may receive less resources due
    to investment of time and money in false
    allegations

69
Applications in Homicide Investigations
  • Two distinct patterns in homicidal offenders
  • Organized Offender
  • Disorganized Offender

70
Patterns of Homicidal Offenders
  • Organized offender may have
  • Planned and rehearsed crime in detail
  • Allowed for variances
  • Conceived crime and locations

71
Patterns of Homicidal Offenders
  • Organized offender may have
  • Determined what tools are needed to efficiently
    deal with victims
  • Determined what is necessary to prevent
    identification and apprehension
  • Left little to chance and selected victim who can
    not be linked to him

72
Patterns of Homicidal Offenders
  • Disorganized Offender is characterized
  • By impulsiveness and thoughtlessness of crime
  • By crime scenes which are messy and chaotic
  • By relying on tools at scene to commit crime

73
Patterns of Homicidal Offenders
  • Disorganized Offender is characterized by
  • Lack of planning leaves abundant clues at scene
  • Offenders ability to approach, obtain, and
    maintain control of the victim throughout crime
    being present

74
Sexual Homicide Characteristics
  • Sexual homicides can be characterized by criminal
    acts performed on the body
  • Exposure of sexual anatomy, insertion of foreign
    objects, redressing of victims may be present
  • Staging may be used to misdirect investigation

75
Sexual Homicide Characteristics
  • Meticulous examination of victims lifestyle and
    examination of offenders past behavior or
    comments concerning the victim may lead to clues
    of the identity of the offender

76
Lust Murder
  • Lust murder is defined as criminal acts involving
    an assault of sexual parts of a body
  • Mutilation of victims body parts occurs
  • Mutilation must have been intentionally inflicted
    postmortem

77
Body Disposal Choices
  • Body location and methodology are clues to
    revealing a prior victim-offender relationship,
    offender sophistication level, degree of planning
    by offender, victim representation of a class of
    people, and offender knowledge of disposal site

78
Body Disposal Choices
  • Abandoning or dumping a body where it fell may be
    a sign of lack of planning or forethought
  • May exhibit a pattern of disorder
  • Offender who conceals body and evidence suggests
    he has thought about commission of crime, and may
    reflect an organized offender

79
Body Disposal Choices
  • Posing of a body by offender may suggest
  • Is leaving body in way that offends discovering
    party or society, overall
  • Offender may be expressing his inner thoughts or
    anger and hatred toward victim or other
    represented by victim- prostitutes, drug dealers,
    etc

80
Body Disposal Choices
  • Each time an offender moves a body, new crime
    scenes are established, and the possibility of
    evidence linking offender to victim increases

81
Body Disposal Choices
  • Moving may infer another step in offender
    process, concealing of body, or movement to a
    specific area noted for an activity lovers
    lane, waste dump, etc.

82
Crime Scene Staging
  • Crime scene staging involves acts that are
    committed to send the investigation off course
    and away from the offender
  • Spouses may stage a robbery or burglary to hide
    murder
  • Innocent people may move body due to being
    personally disturbed by scene

83
Crime Scene Staging
  • Investigator who thoroughly examines crime scene
    may find details which are inconsistent with
    logical progression or evidence presented by
    crime scene
  • Emotional or unemotional displays or
    inconsistencies in stories of witnesses should
    alert investigator to staging
