VANCOUVER -- Coquitlam Mounties are looking for a man they say is unlawfully at large after not returning to a B.C. forensic psychiatric hospital.

According to RCMP, Landon Hayes Kibbe, who is 36, was reported overdue on a day pass from the hospital on Colony Farm Road in Coquitlam on Aug. 17 at about 3:30 p.m. 

Kibbe is described as a white man with short brown hair, a brown moustache and grey eyes. He's 6'2" and has a heavy build. 

Police say he was last seen wearing a white shirt, black hat, black shoes and dark shorts. He also had a black backpack with him.
