Paul Steven Cosner was a 39-year-old used car dealer who disappeared from San Francisco on November 2, 1984. He left his Marina District home to meet a potential buyer for a gold 1980 Honda Prelude he had advertised and told his girlfriend the buyer seemed odd but that he would be back to watch a TV show that evening. He never returned and both Cosner and the Prelude vanished.

Cosner’s car turned up in 1985 after Leonard Lake and Charles Ng were arrested for shoplifting in South San Francisco; the vehicle held some of his personal effects, including his glasses and driver’s license. Lake’s diary mentioned Cosner, and investigators later linked Cosner’s disappearance to the pair and their Wilseyville cabin, where multiple victims were tortured and killed. Cosner’s body has never been found; in 2001 he was officially declared a homicide victim and his family hopes modern DNA methods may one day identify remains.

If anyone knew Paul, saw him or his gold Honda Prelude around November 2, 1984, or has information about possible burial sites connected to Lake and Ng, please come forward.
