Kaitlyn Leddy, 22, vanished from Ardmore, Pennsylvania after being last seen on January 8, 2014. She is a white female, about 5 feet 8 inches tall, 115 pounds, with blonde hair, blue eyes and a small K tattoo on her right hip. On the day she disappeared she wore a red North Face jacket, black pants and black over-the-knee UGG-style boots.

Surveillance shows Kaitlyn walking onto the Benjamin Franklin Bridge in Philadelphia and heading to the bridge’s highest point; footage does not show her leaving the bridge and she has not been seen since. The Lower Merion Township Police Department and the Pennsylvania State Police have investigated. Her case is listed as lost/injured missing and dental records, fingerprints and DNA are on file.

Authorities note suicide by jumping is a leading theory because of where she was last seen, but no body has been recovered and other possibilities — accident, voluntary disappearance or abduction — have been considered without evidence. Anyone with information about Kaitlyn or who may have seen her that day is asked to come forward.
