Summary based on the NamUs case record (MP14690) and 4 other sources
Fredrick Manuel Aragon, 28, was last seen on July 18, 1987, at his home in Vacaville, California. On that day, he was wearing a red-checkered long-sleeved shirt and jeans. Fredrick, who had a behavior disorder, wore eyeglasses and had two missing front teeth replaced with false teeth. At the time of his disappearance, he was driving a red 1973 Datsun pickup truck, which was later found abandoned on February 2, 1988, near the entrance to the Presidio Army Base in San Francisco.

Despite the discovery of his truck, no further trace of Fredrick was found, and his case has remained unsolved for over three decades. The circumstances of his disappearance are considered suspicious, but there have been few leads in the investigation. His family continues to search for answers, and the Vacaville Police Department remains the primary investigating agency.
