Summary based on the NamUs case record (MP9350) and 8 other sources
David Ronnal Provost, a 20-year-old civilian merchant seaman, was last seen on August 21, 2002, after leaving the USNS *Bold* in San Diego, California. Provost reportedly intended to visit Tijuana, Mexico, but did not return to his ship the next day, missing his scheduled departure. He has not been seen or heard from since. His disappearance was not reported until August 23, 2002, leading to concerns about his whereabouts.

After his disappearance, Provost's ATM card was used multiple times in Tijuana, withdrawing around $1,300 to $1,400 from his account. There were also suspicious activities involving his card at a local hotel, where it was used to pay for a room under a different name. His family later received Provost's Florida driver's license in the mail, but the envelope was postmarked from San Diego with his name misspelled and no return address. There were also mysterious phone calls made to his grandmother, with Spanish-speaking individuals involved, raising suspicions of foul play.

Provost's case remains unsolved, and authorities suspect he may have been a victim of a kidnapping or robbery in either San Diego or Tijuana. Despite extensive investigations, his fate remains unknown, and foul play is strongly suspected.

Last Seen: Aug 23, 2002
