Tuan Tran, 54, was last seen November 19, 2017, off the coast of Half Moon Bay, California. He was believed to be aboard a 17-foot vessel near Martin’s Beach that was later found spinning out of control. One occupant of that boat was discovered deceased, but Tuan remains missing and has not been found.

Authorities consider the possibility that he was a victim of a maritime accident, and searches and investigations have not resolved his whereabouts. Few public details are available about the timeline between the boat being found and recovery efforts for Tuan.

If anyone has information about Tuan’s movements that day or about the vessel near Martin’s Beach, please contact local authorities.
