Summary based on the NamUs case record (MP21704) and 2 other sources
Wallace L. Vaughan, a 27-year-old man from Oroville, California, went missing on January 1, 1990. His last known address was on Canyon Highlands in Oroville. However, his family did not report him missing until a decade later due to threats they had received, which delayed the investigation into his disappearance. Authorities suspect that Vaughan may have been involved in drug activity at the time he vanished, and foul play is strongly suspected in the case.

Despite the lack of immediate reporting, investigators have treated Vaughan’s case as a possible homicide, given the circumstances surrounding his disappearance. His case remains unsolved, and law enforcement continues to seek any information that could provide leads to his whereabouts or the events leading to his disappearance.
