Ritual and Signature in Serial Sexual Homicide

by

Since the early case studies of sexual murder by von Krafft-Ebing, offenders have been reported to engage in various crime scene behaviors that are unnecessary in the commission of the homicide. For example, several of the individuals von Krafft-Ebing cited not only killed their victims, but filled their mouths with dirt, pulled their hairpins out, pressed their hands together, subjected them to humiliation and torture, and often took something from them of little value. Authors of other early publications found similar behavior in sexual murderers. Many investigators concluded that these seemingly unnecessary activities (i.e., unnecessary for successfully accomplishing the crime) served a psychological purpose. The offender needed to engage in such actions to feel sexually gratified killing the victim was not sufficient.

Such crime scene behaviors, which more often than not are repetitive, have been found to be an outgrowth of the perpetrator’s deviant sexual sies, wherein the murder and the repetitive acts are parts of the offender’s sexual-arousal pattern.

Body Disposal Patterns of Sexual Murderers: Implications for Offender Profiling

by

Abstract

Offender profiling postulates that crime scene behavior should predict certain offender characteristics. The aim of this study is to investigate the relationship between offender characteristics, situational factors, and body disposal patterns. Sequential logistic regression analysis on a sample of 85 sexual murderers shows that those who were in a relationship at the time of the crime and who present organized psychological characteristics are more likely to move the victim’s body after the homicide. However, when the victim is older and a conflict with the offender occurred prior to the crime, the body is more likely to be left at the crime scene. Implications for offender profiling are discussed in light of the results...

Prostitute Found Dead Near Ny Serial Killer’s Dumping Ground Possibly Murdered, Says Famed Coroner

by

AMITYVILLE, N.Y. –  The remains of a New York-area escort whose body was found in 2011 near a mass grave of prostitutes were buried Thursday, four days after a renowned coroner told Fox News she may have been murdered a development that could be a break in the hunt for a Long Island serial killer.

Shannan Gilbert, 23, of Jersey City, N.J., disappeared May 1, 2010, after visiting a client in the gated community of Oak Beach on a barrier island off Long Island's south shore. A months-long search for her first led to the bodies of four other prostitutes, each strangled and stuffed in burlap bags along Ocean Parkway, a 15-mile road that spans Jones Beach, roughly a mile from where they would later find Gilbert's body, in December 2011.

It's extremely rare for a young woman to die of drowning yards away from where four young women have clearly been murdered. The statistics don't go along with that."...

The Nature And Dynamics Of Sexual Homicide: An Integrative Review

by

Abstract

The author reviews the definitions, epidemiology, evolving research, offender, and offense characteristics of sexual homicide, a form of intentional killing that occurs in less than 1% of homicides in the United States. Although the extant research is limited by very few comparative studies, repetitive use of small, nonrandom samples, retrospective data, no prospective studies, and the absence of any predictive statistical analyses, the yield over the past 100 years is impressive. The author advances a clinical typology of sexual murderers. The first group of compulsive sexual murderers leaves behind organized crime scenes and are usually diagnosed with sexual sadism and antisocial/narcissistic personality disorders. They are chronically emotionally detached, often primary psychopaths, are autonomically hyporeactive, and the majority experience no early trauma. The second group of catathymic sexual murderers leave behind disorganized crime scenes and are usually diagnosed with a mood...
