Phillip Cabot Lloyd Martin, 47, vanished from Stockton, California on September 30, 1993, after driving his ex-wife to work that morning and failing to return later to pick up their daughters. He had been following that routine since the school year began. Martin was living a transient lifestyle and worked as a carpenter and construction laborer; he resided in a gold 1987 Chevrolet Celebrity. His vehicle was later found abandoned and burned in a vineyard near Pearson and Morse Roads, south of Lodi, but Martin’s body has never been recovered.

The case drew renewed attention in the early 2000s because of possible links to Wesley Shermantine and Loren Herzog, known as the Speed Freak Killers. Martin’s daughter said her father had worked with Shermantine, identified him in a photo lineup when she was a child, and believed Martin, Shermantine, and Herzog had used drugs together. In 2012 Shermantine led investigators to a well in Linden that contained about 300 human bones and personal effects; he said the well held up to twenty victims and attributed the killings to Herzog. Martin’s remains were not among those identified. No arrests have been made in Martin’s disappearance and foul play is strongly suspected.

Does anyone have memories of Martin, his gold 1987 Chevrolet Celebrity, or his movements around Stockton in late September 1993?
