James Christophe Wray Carlson, known to friends as Rat, was 43 when he vanished from Watrous, Saskatchewan. The last confirmed sighting was the evening of May 14, 2008, at a local business. He was a heavy-duty mechanic and did not show up for work the next day — behaviour his family described as out of character.

Carlson is described as a Caucasian male, about 5 feet 8 inches and 180 pounds, with brown hair and brown eyes, a bowed right leg, a scar on his right wrist and a pierced left ear with a diamond earring. On May 14 he was wearing a black short-sleeve T-shirt, black track pants and black running shoes. His work truck was found abandoned in a field near Allan on May 19, 2008, with all of his tools inside. Police later said evidence at his Watrous home suggested foul play.

His white 1985 Chevrolet Monte Carlo was recovered in a rural area near Rosthern in May 2010; the interior had been doused in automotive fluid in an apparent attempt to destroy evidence. No trace of Carlson himself has been found. If anyone knew James, saw his truck or car after May 14, 2008, or has information about his disappearance, please come forward.
