Damon Washington was 18 when he was found dead in Diamond Bar, California, on November 30, 1991. Born July 31, 1973, in Los Angeles County, his death was investigated as foul play after he was discovered under suspicious circumstances.

Authorities questioned several people over the years but no arrests were announced and the case remained unsolved. The family pursued civil suits against individuals they believed were involved, and the investigation has been periodically revisited by cold case efforts as forensic methods advanced.
