Investigators say 19-year-old Andrew David Sheaffer and another man talked the woman into giving them her keys in the parking lot of a Carlisle Walmart on Monday.
Police say the men had her lie down in the back of the sport utility vehicle while they drove recklessly, swerving wildly and hitting the brakes to toss the woman around the inside of the vehicle. The woman said the men wouldn't let her get out.
Investigators say the men also intentionally damaged the vehicle.
A phone listing for Sheaffer could not immediately be located. Police are still trying to identify the second suspect.
