Shawn Paul Houston was 28 when he disappeared from Brinnon, Washington, after a Feb 8, 2005 incident involving a Sea-Doo personal watercraft. He was reported unable to start the engine and drifted away from shore; the Sea-Doo was later found overturned but there was no sign of Shawn. His vehicle was recovered at the scene and no other vehicle was known to be involved.

The Jefferson County Sheriff’s Office led an extensive search that included divers in the frigid water, but no trace of Shawn was found. Investigators collected DNA from his mother and maternal uncle to assist with future identification if remains are recovered. Authorities have described the likely scenario as a tragic accident connected to the overturned watercraft, but there is no body or conclusive evidence establishing what happened.

Anyone who knew Shawn, his routine in Brinnon, or who may have been on the water that day is asked to come forward with information.
