Rosemarie Timperley, 20, vanished from a care home in Okmulgee, Oklahoma in the early hours of February 2, 2016. Staff last saw her about 2:30 a.m.; a 4:00 a.m. bed check found her bedroom locked and, after entry through a bathroom, the room empty with the window open. Some of her belongings were scattered across the facility’s yard.

Rosemarie is autistic and described as having the mental capacity of a young teenager. She had been restless the night before, had recent medication changes that reportedly produced delusions, and was upset about an upcoming hospitalization. At the time she disappeared she was wearing a gray t-shirt, pink Tweety Bird pajama pants, and tan cowboy boots, and may have had a black jacket. A few days earlier she was overheard on the phone with a man she called Uncle Charles; her family says no relative by that name is known.

Investigators have noted Rosemarie’s trusting nature and considered possibilities including human trafficking. Who knew Rosemarie, saw her that night, or can identify Uncle Charles?
