Sexual Homicide by Older Male Offenders.

Recent research has expanded our understanding of sexual homicide offenders (SHOs). However, little exists beyond case reports for older SHOs. We characterized male SHOs ≥ 55 years, comparing them to typical adult male SHOs who are in their 20s.

Investigation, science, and research partner to solve elderly woman's shocking homicide.

As the investigation and prosecution of sexual homicide cases becomes increasing complex, law enforcement agencies are utilizing alternative avenues of investigative assistance. In 2004, the Oakland County, Michigan Sheriff's Office was faced with the horrific sexual assault and murder of an elderly woman. Although familiar with violent crime, this extremely violent and unusual case motivated the police to enlist the help of forensic scientists and FBI violent crime researchers to assist their investigation.

Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure.
