California Highway Patrol closed down an offramp of Interstate 15 in Mission Valley to look for a crash victim's lost hand Thursday night.

A person suffered life-threatening injuries after slamming into a guardrail on the southbound I-15 offramp to Friars Road, CHP officials said.

A caller reported the driver was reaching high speeds before the crash.

After the driver was taken to Sharp Memorial Hospital, CHP officers searched for and located the person's hand.

Investigators believe the person was driving under the influence during the crash.
