Pittsburgh police are looking for a 15-year-old boy who is considered endangered after leaving a hospital Saturday morning.

Police said Timothy Powell was reported missing after leaving a hospital in the 3800 block of O’Hara Street. The hospital was not named.

Police said Powell is known to have mental health challenges and may be drawn to areas with water.

He also fears law enforcement, which they say could affect how he responds if approached.

Powell is described as being 5 feet 7 inches tall, about 130 pounds, with blue eyes and blonde hair. He was last seen wearing a gray T-shirt, blue jeans and shower shoes.

Anyone with information on Powell’s whereabouts is asked to call 412-323-7141 or 911.
