David Ronnal Provost was a 20-year-old civilian merchant seaman last seen on August 21, 2002, after leaving the USNS Bold in San Diego. He reportedly planned to visit Tijuana but did not return to the ship the next day and missed his scheduled departure. His disappearance was not reported until August 23, 2002.

After he vanished, Provost’s ATM card was used multiple times in Tijuana, withdrawing roughly $1,300 to $1,400. The same card was later used to pay for a hotel room under a different name. His family received his Florida driver’s license in the mail in an envelope postmarked from San Diego, with his name misspelled and no return address. Spanish-speaking callers placed mysterious calls to his grandmother, prompting investigators to suspect kidnapping or robbery in San Diego or Tijuana.

No confirmed explanation for his disappearance has been established and foul play is strongly suspected. If anyone knew David, saw him in August 2002, or has information about the card, the mailed license, or the phone calls, please come forward.
