EUREKA (AP) — Officials have identified a jawbone found at the mouth of the Klamath River as that of a teenage boy who disappeared in 2011 after fleeing a stolen vehicle.

The Eureka Times-Standard says the Del Norte County Sheriff's Office identified the bone as belonging to 15-year-old Cody Conoboy.

In January 2011, in what police said was a stolen car, Conoboy and three other juveniles led authorities on a chase on State Route 96.

The boys fled the vehicle after it overturned several times, and Conoboy was never found.

Investigators later found footprints and determined he had jumped from a bridge overlooking the Trinity River.

Conoboy was presumed dead after one of his shoes was found 6 miles away from the accident site.
