Oakland County Child Killer

The Oakland County Child Killer (OCCK) is the name given to the perpetrator(s) responsible for the serial killings of at least four children in Oakland County, Michigan, between 1976 and 1977. The children who were murdered were last seen in the company of a young to middle-aged man with a defined face, sharp nose and long black hair. The victims were held captive before being killed, and the four deaths triggered a murder investigation, which at the time was the largest in U.S. history, with Detroit's two daily newspapers, as well as the area's numerous radio and television stations, covering the case. A presentation on WXYT radio, titled Winter's Fear: The Children, the Killer, the Search, won the Peabody Award in 1977.

Forensic DNA testing has indirectly implicated two suspects, one of whom has since died, with the other serving life in prison for sexual offenses against children. A DNA profile of the main perpetrator was created from samples taken from some of the victims' bodies, but does not match the DNA of anyone named in connection with the case; the perpetrator's identity is unknown.
