Bruce Boughton was 23 and stationed at Travis Air Force Base when he was last seen on May 4, 1975. He lived in Vacaville, California; his wife had moved away shortly before his disappearance and he was believed to have gone to Lake Berryessa. His vehicle, an orange 1971 Datsun 110, is linked to the case. Nothing appears to have been taken from his apartment.

Bruce is described as 5 feet 6 inches tall, about 140 pounds, with brown curly hair and blue eyes. He was not reported missing until 1979, and despite that delayed report investigators have not confirmed any leads. Very little else is known about what happened after May 4, 1975.

If anyone knew Bruce, saw his Datsun around Lake Berryessa in May 1975, or has information about his movements that spring, please come forward.
