Shinho Steve Seo, 34, was last seen January 1, 2004, while spear fishing and scuba diving about 60 feet down off Punta Prieta, Mexico, in the Sea of Cortez. His diving companions did not see him resurface; they later found his speargun floating and a fired spear with its cord trailing into a coral cave, but there was no trace of Seo.

Seo worked as a mortgage banker in Norwalk, California, and was originally from South Korea. He was wearing a black neoprene wetsuit, a mask, and a snorkel. Authorities have classified the incident as lost/injured missing and Los Angeles County continues to investigate, though the disappearance is believed to be accidental and he is presumed to have drowned.

If anyone was diving in the Punta Prieta area on January 1, 2004, or has information about that day’s dive, please share what is known.
