PORTERVILLE, Calif. (AP) - Authorities have identified the victims of a plane that crashed in the Central Valley en route from San Diego to Fresno.

The Kern County coroner's office on Tuesday said James Johnston of Sanger and Jacob Curiel of Imperial died in the crash. Their age have not been released.

Federal Aviation Administration spokesman Ian Gregor says the single-engine Beechcraft BE-35 disappeared from radar and radio contact around 4 p.m. on Sunday. The small airplane went down in a mountainous area about 35 miles northeast of Bakersfield.

A sheriff's helicopter found the crash site the next day. Both men were deceased at the site.

The FAA and the National Transportation Safety Board are investigating.
