Summary based on the NamUs case record (MP41467) and 6 other sources
Ka Hung Chiu, a 22-year-old man from San Francisco, California, was last seen on May 15, 1986. At the time of his disappearance, he was living in San Francisco, and his vehicle was later found abandoned on the Golden Gate Bridge, sparking concerns about his fate. Chiu stood 5'11" tall, weighed 143 pounds, and had black hair and brown eyes.

The circumstances of his disappearance remain unclear, but the discovery of his car on the bridge has led some to speculate that he may have taken his own life, though no conclusive evidence has surfaced. Despite ongoing investigations, including by the San Francisco Police Department, no additional details have emerged, and Chiu's whereabouts remain unknown. The case is still classified as an endangered missing person.
