Summary based on the NamUs case record (MP32025) and 5 other sources
Martin Christopher Austin, 20, was last seen on March 15, 1974, in Fairfield, California. He was living at home and was last seen by his mother at 8:00 a.m. that day. Later, Martin went to Solano Community College, where he collected his paycheck. However, he never reported for work the next day, and he has not been heard from since.

On March 17, 1974, Martin's white 1971 Honda Z600 was found abandoned in the parking lot of Linda Mar Shopping Center in Pacifica, California. At the time of his disappearance, Martin was 6'1" to 6'2", weighing around 170 to 180 pounds, with brown hair and hazel eyes. He had a full beard and mustache, and he was last seen wearing blue jeans, a gray t-shirt, a brown suede jacket, and size 11 hiking boots with lug soles.

Foul play is suspected in Martin's case, but despite the efforts of authorities, no significant leads have surfaced over the years. His case remains unsolved, and investigators are still seeking any information that could help bring closure to his disappearance. The Fairfield Police Department continues to handle the investigation.
