PHILADELPHIA (CBS) — Philadelphia police are asking for the public’s help locating a missing 23-year-old woman with autism.

Police say Janetta Graham was last seen in the area of Broad and Morris Streets around 8:30 a.m. Monday by a family friend.

Authorities say she may have escaped her home through a kitchen window, because both the front and back doors were double locked.

Graham has been reported missing three times in the past, and is known to ride SEPTA buses and trains.

Anyone with information regarding where she may be is asked to contact Detectives at 215-686-3013, or call 911.
