OKLAHOMA CITY (AP) - Oklahoma City police say they found no evidence that the death of businessman Aubrey McClendon in a vehicle crash a day after he was indicted by a federal grand jury was anything other than an accident.

Capt. Paco Balderrama said in a statement: "Our investigators found no information or evidence which would compel us to believe this was anything other than a vehicular accident."

Police previously said the former Chesapeake CEO was driving 78 mph when his sport utility vehicle hit a bridge support and burst into flames and that there was no evidence suggesting he tried to avoid the crash.

His death came a day after his indictment on a bid-rigging charge. He had vowed to fight the charge.
