Understanding Different Types of Serial Killers
Serial killers come in various forms, from those driven by sexual gratification like the Boston Strangler to contract killers motivated by money. The distinction lies in their behavior, motivations, and psychodynamics. Psychologists like Dr. Lewis Schlesinger study these differences to shed light on their complex nature.
Unraveling the Complexities of Serial Sexual Murder
Serial sexual murder remains a challenging subject to comprehend due to its lack of inclusion as a paraphilia in diagnostic manuals. The fusion of sex and aggression in these cases is vital, often involving additional acts beyond killing for complete sexual satisfaction. Contrary to popular belief, sexual penetration is not a definitive marker, as violence can replace it in these crimes.
Exploring the Motivations Behind Serial Killers
Contrary to common assumptions, trauma or poor parenting are not singular triggers for serial killers. Dr. Schlesinger emphasizes that these individuals do not necessarily have a history of sexual assault or rape. The complex biopsychosocial nature of their motivations often involves a combination of neurobiological, hormonal, and environmental factors.
Distinguishing Psychopathic Traits and Behavior Patterns
Psychopathy, sociopathy, and antisocial personality disorder are often conflated terms in discussions about serial killers. Psychopathic traits, characterized by a lack of emotional attachment, influence how murders are carried out. The distinction lies in their ability to plan crimes and inhibit impulses, impacting the forensic awareness and organization of their actions.
From Jack the Ripper to Jeffrey Dahmer to the Gilgo Beach killer, serial killers have long inspired public fear – and public fascination. Louis Schlesinger, PhD, a professor of psychology at the John Jay College of Criminal Justice in New York and co-investigator of a research project on sexual and serial murder with the FBI Behavioral Science Unit, talks about what we really know about these murderers’ motivations and their methods, how some manage to avoid capture for so long, and how forensic psychology research can help investigators solve cases.
