Phillip Cabot Lloyd Martin, a 47-year-old man from Stockton, California, disappeared on September 30, 1993, under suspicious circumstances. On the day he vanished, he had driven his ex-wife to work but never returned to pick up his daughters from school, raising immediate concern. At the time of his disappearance, Martin was living a transient lifestyle, working as a carpenter and laborer while residing in his gold 1987 Chevrolet Celebrity. His vehicle was later found abandoned and burned in a vineyard near Lodi, California. Martin was reported missing on October 11, 1993.
A key aspect of this case is the suspected involvement of the notorious "Speed Freak Killers," Wesley Shermantine and Loren Herzog, who were convicted for multiple murders in the 1980s and 1990s. Martin had known ties to Shermantine, with his daughter identifying Shermantine in a photo lineup and stating that her father had worked and used drugs with both men.
Investigators believe Martin may have been one of their victims, though his remains have never been recovered. While Shermantine has led authorities to other victims' burial sites, Martin's fate remains uncertain, and foul play is strongly suspected.
Despite extensive investigations and the identification of other victims linked to the killers, Martin’s case remains unsolved. His disappearance is still treated as an open case, with authorities continuing to search for answers and any leads that might help uncover what happened to him.Last Seen: Sep 30, 1993
