Maurice Anthony Rock, 37, was last seen alive in July or August 1984. His remains were recovered on June 6, 1985, in Wilseyville in Calaveras County, California. Investigators later tied his death to Leonard Lake and Charles Ng, who operated from a remote Calaveras County cabin and committed a series of kidnappings, torture and killings in the early 1980s.

Lake and Ng’s crimes included victims of both sexes and children; evidence recovered at the cabin reportedly included human remains, videotapes and journals. Lake died in custody in 1985 after ingesting cyanide sewn into his clothing; Ng was later convicted on multiple counts of capital murder. Maurice Rock’s remains were among those that helped establish the scope of the perpetrators’ actions.

Did anyone who knew Maurice Rock in 1984 recognize him or have information about his last known movements?
