Sean Patrick Friel, 28, was last seen March 20, 2004, after checking out of a Marriott in Solana Beach, California. He had been preparing to move to Los Angeles for a job as a computer programmer and was described as mild-mannered and calm. Prior attendance at Zen and Buddhist retreats led some to suggest he might have chosen to disappear, but that remains speculation.

On March 30, 2004, his 1993 gray Nissan truck was found abandoned near the entrance to Torrey Pines State Reserve on the Pacific Coast Highway. The truck still contained his passport, luggage, computer, and cellphone. Several days later searchers found his shoes, socks, and eyeglasses neatly placed near a cliff overlooking the ocean; despite rain in the interim, the items showed no water damage. His credit cards were later used in Brazil, though who used them is unclear. An extensive search has turned up no trace and he is listed as endangered missing.

If anyone knew Sean, saw his truck, or has information about the Torrey Pines area in March 2004, please share what you remember.
