Serial murder of six victims by an African-American male

A case of a 22-year-old African-American male who sexually assaulted and murdered six African-American females who were strangers to him is reported. Formal study of the subject eight years after the homicides revealed a mildly mentally retarded individual who had, at various times, diagnosable anxiety and depressive disorders. His diagnosed paraphilia was sexual sadism. He also met criteria for both Antisocial and Schizoid Personality Disorder, which are discussed in the context of the comorbidity of psychopathy and schizotypy among some serial murderers. Traumagenic events from his childhood and adolescence included an absent father, sexual and physical abuse, the witnessing of adult sex, and the viewing of violent pornography.
