Summary based on the NamUs case record (MP51019) and 5 other sources
William Darrell Bowman, aged 33, was last seen on February 28, 1990, in Benicia, California. He disappeared under mysterious circumstances, with few clues available at the time. Bowman was reportedly seen at around 9:00 p.m. near the 680 Bridge, which connects Benicia to Martinez. Witnesses claimed to have seen a man matching Bowman's description on the bridge shortly before he apparently jumped off. Despite these accounts, his body was never recovered, and the exact events surrounding his disappearance remain uncertain.

Bowman, who stood 6'2" and weighed 195 pounds, had distinguishing features including an eagle tattoo on his right forearm. At the time of his disappearance, he was wearing a maroon-striped shirt, blue jeans, and sneakers. Given the nature of his disappearance, some have speculated that Bowman took his own life, though no definitive conclusion has been reached. Authorities conducted investigations, but no new leads have surfaced in the decades since.

This case remains open, with Bowman's name listed in various missing person databases. The Benicia Police Department continues to be the primary agency handling the case, and they encourage anyone with information to come forward.
