Police in Mercer County say a possible carjacker apparently removed a sleeping 80-year-old woman from her parked car before stealing the vehicle and leaving her in a driveway.

Hamilton police say that the woman told them she'd fallen asleep inside her car around 9 p.m. Wednesday. It was parked in a driveway at the time. She told police that she woke to find the vehicle missing around 4 a.m. Thursday.

Police say the woman didn't remember what happened and had a bruise and abrasion on her face.

Authorities found the empty vehicle Thursday afternoon in Trenton.

No arrest has been made, according to police.
