CORINNE, Utah (AP) _ An armored car driver stole $2.5 million from the vehicle while two guards slept in the bunk section, the FBI said Friday.

The driver, Jared Layne Gray, 26, of Murray ''turned up missing and hasn't been seen since,'' said Box Elder County Sheriff's Detective Ken Adams.

The theft, which occurred Thursday at a service station off Interstate 15 in northern Utah, was reported by the other guards. The money was being shipped from Boise, Idaho, to the Federal Reserve Bank in Salt Lake City.

FBI agent Don Kirby said the guards were asleep when the Wells Fargo driver pulled off the freeway. After taking the money, he apparently blocked the 38,000-pound truck's front doors, trapping the guards inside, the agent said.

The guards got the attention of the service station attendant, who opened the door, said Kirby.

Gray was charged in a federal complaint with embezzling.

Wells Fargo Armored Service Corp. headquarters in Atlanta referred calls to its parent company, Baker Industries of Parsippany, N.J. A secretary said a spokesman had left for the day and no other company officials could comment.
