Oklahoma authorities said the March 2 car crash that killed oil man Aubrey McClendon a day after he was indicted does not appear to be suicide, NBC News reported.
McClendon, who was the founder and former CEO of Chesapeake Energy, had been indicted by a federal grand jury for allegedly trying to rig oil prices. If found guilty, McClendon would have faced up to 10 years in prison.
McClendon died when he slammed his car into a highway embankment and the car burst into flames.
"We have not found anything to lead us to believe Mr. McClendon's death is a suicide," said Oklahoma City police Capt. Paco Balderrama. "We can't rule out suicide as a cause of the crash, but we have found no evidence which would lead us to believe it was a suicide."
The Oklahoma State Medical Examiner's Office is still investigating the death.
