A car crash that killed Oklahoma oil man Aubrey McClendon was suspicious, but not a suicide, so authorities say.
Oklahoma City police were investigating the March 2 wreck that killed McClendon just a day after he was indicted by a federal grand jury for allegedly trying to rig oil prices.
The founder and former CEO of Chesapeake Energy and a part owner in the Oklahoma City Thunder basketball team died when he he slammed his speeding Chevrolet Tahoe into a highway embankment and the vehicle burst into flames.
McClendon, who faced up to 10 years in prison, denied the charges.
