Ben Story said he and his family were asleep in their Larkspur home, 30 miles south of Denver, during the joyride early Friday. He said the bear got into the car through an unlocked door and knocked the shifter into neutral, which sent it rolling backward 125 feet.
Story thinks the door slammed shut when the car jolted to a stop, trapping the bear inside.
Neighbors had called 911, and deputies freed the bear by opening the door with a rope from a distance.
Nobody was hurt, but Story said he needs a new car - the bear shredded the interior.
