Kidnapping of Ripken’s mom still unsolved (VIDEO)

WASHINGTON – Nearly four months after the mother of Orioles Hall of Famer Cal Ripken was kidnapped outside her home, police are still still trying to track down the man who abducted her.

The Aberdeen Police Department has released enhanced images of the suspect taken at a Walmart store in the 6700 block of Chesapeake Center Drive in Glen Burnie and at a Walmart in the 100 block of Carroll Island Road in Middle River, Md.

Officials are also trying to identify the owner and occupants of a Dodge minivan seen in the images. This is not a suspect vehicle, authorities say.

Below is a video of the suspect:

On July 24, Ripken was abducted at gunpoint, bound and driven around in her car for 24 hours before she was returned to her home unharmed.

Anyone with information is asked to call 410-272-2121.
