Summary based on the NamUs case record (MP30326) and 8 other sources
Steven Allan Davis, 23 years old at the time, was last seen on October 31, 1986, in San Francisco, California. He left his job in downtown San Francisco that afternoon and has not been seen or heard from since. Standing at 6'2" and weighing around 170 pounds, Davis is described as having brown hair, blue eyes, and a distinctive scar above his left eye. His case remains unsolved, with very few details emerging about what might have happened after he left work that day.

Davis' disappearance is classified as endangered, though no definitive information has come to light to suggest foul play or other causes. Despite having his dental records and fingerprints available for identification purposes, efforts by law enforcement, including the San Francisco Police Department, have yet to yield any conclusive leads. His case continues to be listed in national databases like NamUs and the Doe Network, keeping hope alive that further information may eventually surface.

The circumstances surrounding his disappearance remain mysterious, with his family and investigators continuing to seek any potential clues that could help solve the case. Although over three decades have passed, Davis’ family still hopes for answers that could bring closure to his case.
