Claxton Mark Mayo, who went by Mark, was 43 when he vanished after a single-vehicle crash on Interstate 20 in Monroe, Louisiana, on March 30, 2011. His Chevrolet Suburban reportedly flipped three times; he was seen on surveillance entering a truck stop in Ouachita Parish with visible injuries but was never recorded leaving on the cameras available. There is unconfirmed speculation he may have left through a back entrance, possibly accompanied by a truck driver.

At disappearance he wore a white Hanes crew-neck t-shirt, a gray fleece zip-up jacket, blue Old Navy slacks, and brown leather shoes with side buckles. He is described as a Caucasian male with black, graying hair and hazel eyes, with a faded tattoo of a sword through a spiderweb with flames on his left shoulder and arm, a left nipple piercing, and surgical and fracture scars noted in his medical history. Concern that a closed head injury from the wreck could have caused amnesia is a central part of the case. If anyone has information about Mark’s movements after the truck stop or remembers seeing him that day, please share what was seen.
