Offender Profiling in Psychopathy

FPsyc3400 Week 5: Offender Profiling

Differentiating Offender Profiling

  • Offender profiling is not the same as Investigative Psychology.

  • Mandated by Dr. Shannon Vettor.

Pragmatic Typology of Serial Murderers (Holmes & DeBurger, 1988; Holmes & Holmes, 1998)

    • Motivation: Kill due to visions.

    • Characteristics: Generally psychotic, chaotic, and disordered actions.

  • Mission-Oriented

    • Motivation: To rid society of specific groups (e.g., prostitutes, runaway kids, racial groups).

    • Characteristics: Quick execution; no pre-mortem/post-mortem activities.

  • Hedonistic – Thrill

    • Motivation: Kills for the pleasure and excitement derived from killing.

    • Characteristics: Usually involves a long process, with careful planning.

  • Hedonistic – Lust

    • Motivation: Kills for sexual gratification.

    • Characteristics: Involves both pre-mortem and post-mortem activities; highly planned.

  • Power/Control-Oriented

    • Motivation: Pleasure derived from exerting power over victims.

    • Characteristics: Often kills victims when they relinquish hope for survival and submit.

Theory-led Classification: Power, Anger, and Sex (Groth et al., 1977; 1979)

  • Anger

    • Characteristics: Physical brutality, excessive violence, and use of sex to express anger.

    • Focus on tormenting victims, which includes the use of fusion of sexual aggression with physical violence.

  • Power

    • Characteristics: Expression of mastery and control; includes torture and explicit abusive acts.

    • Often punishes victims through sexual acts; force is used primarily to gain control.

  • Sadistic

    • Characteristics: Combines sexual possession with acts of violence; fantasies of attacks are prevalent.

    • The duration of the act is often longer, indicating meticulous planning and revenge motivations.

Factors in Profile Analysis

  • Motivation

    • Various motivations influence offender behavior.

  • Victim Selection

    • Specific characteristics may relate to acquaintance or targeted victim profiles.

  • Weapon Selection and Use

    • Evolution in weapon choice; varying from planned uses to spontaneous acts.

  • Level of Planning

    • Differences in planning between rape and murder scenarios: both planned and unplanned murders exist.

  • Offender Characteristics

    • Demographics such as age, history of criminal acts, and social behavior influence criminal profiles.

    • e.g., Offenders in their mid-20s may have a background in sexual offenses, social isolation, and troubled military service.

Additional Classifications of Sexual Offenders (Massachusetts Treatment Centre Rape Classification System: MTC:R3)

(Knight & Prentky, 1990)

  • Opportunistic

    • Characterized by impulsiveness; may have varying social competence and seek immediate sexual gratification.

  • Pervasively Angry

    • Involves hatred with expressive violence; often features a strong emotional response.

  • Vindictive

    • Driven by power and control; sexual violence often entails humiliation/degradation of victim.

  • Sadistic vs. Non-sadistic

    • Distinction between those who derive pleasure from the fusion of sex and violence and those who engage in violent acts without sexual intent.

Classification Model of Sexual Murderers (Clarke & Carter, 2000)

  • Sexually Motivated Murderer

    • Defined as engaging in detailed and sophisticated masturbatory fantasies about killing specifically targeted victims, characterized as sadistic.

  • Sexually Triggered Murderer

    • Commits aggressive yet controlled murder to silence victims to avoid detection; less planning evident in the act.

  • Grievance Motivated Murderer

    • Commits uncontrolled murder fueled by victim’s behavior during assault; often involves extreme humiliation or violence indicative of a loss of control.

  • Neuropsychological Dysfunction Sexual Murderer

    • Associated with neuropsychological deficits; not strictly a typology, but highlights specific offender motivations that might be unclear.

Behaviors in Sexual Assaults

  • Illustrated in Figure 1, showcasing variables and behaviors observed in 66 sexual assaults, capturing characteristics of interactions such as:

    • Weapon Use: Various forms include binding, blindfolding, and gagging.

    • Victim Treatment: Ranging from verbal participation to impersonal treatment, impacting dynamics of control and intimacy.

Five-facet Classification of Sexual Offenders (Canter & Heritage, 1990)

  • Introduced to categorize offenders based on nuanced behaviors and characteristics unique to sexual offenses, aligning with prior classification systems and case studies.
