Summary based on 5 sources
Fredrick Manuel Aragon, a 28-year-old Hispanic male, was last seen on July 18, 1987, at his residence in Vacaville, California. At the time of his disappearance, he was 6 feet 3 inches tall and weighed approximately 185 pounds, with black hair and brown eyes. He was last seen wearing a red-checkered long-sleeve shirt and blue jeans. Aragon has a diagnosed behavior disorder, wears glasses, and may have had a mustache. He also had two missing front teeth that were replaced with false teeth.

Aragon was driving a red 1973 Datsun pickup truck when he went missing. This vehicle was later found abandoned on February 2, 1988, on Lombard Street near the entrance to the Presidio Army Base in San Francisco. The discovery of his truck, however, did not provide any clues as to his whereabouts.

The circumstances surrounding Fredrick Aragon's disappearance are considered suspicious, and his case remains an unsolved endangered missing person case. The Vacaville Police Department is the investigating agency, and the case number is 87-04703. Over the years, few details have emerged in the investigation, and his family continues to seek answers. The case is listed in the State of California - Department of Justice's missing person database.
