What on earth happened to Charlie Sheen's car?

Actor Charlie Sheen's Mercedes is towed out of a ravine after it was found overturned hundreds of feet down a cliff near his home early Friday.

The actor's stolen Mercedes was found overturned hundreds of feet down a cliff near his Sherman Oaks, Calif., home early Friday, and police say there's no evidence anyone was in the car when it went into the ravine.

A Bentley was later found off the same road nearby Friday afternoon, and police said three other cars were broken into in the same area. Police were investigating whether the incidents were linked.

Police got an emergency call about 4 a.m. from an alert system that notifies emergency officials when there is a problem with a vehicle, Officer Wendy Reyes told the AP. About the same time, Sheen called police to report the theft, Officer Bruce Borihanh said.

Police and firefighters found the car 300 to 400 feet down a cliff, upside-down in a brushy ravine. They searched on foot and with an infrared-equipped helicopter but found no one.
