Aubrey McClendon, part-owner of the Oklahoma City Thunder and one of the first CEOs to frack in Pennsylvania, was killed in a mysterious car crash a day after being indicted on federal antitrust charges.

McClendon's SUV was going "well above the speed limit" and there was "no indication" he tried to change course before the vehicle plowed into a wall supporting a bridge, according to Oklahoma City Police Department.

The vehicle immediately caught fire and burned completely. Firefighters responded to the incident shortly after 10 a.m. Wednesday.

Police say he drove into the wall at a high rate of speed, but would not call it a suicide. The crash remains under investigation.

McClendon, the 56-year-old founder and former CEO of Chesapeake Energy, was the only passenger.

He was part of a group that bought the Seattle Supersonics and moved the NBA team to Oklahoma City in 2008.

McClendon's death comes a day after he was charged with conspiracy for rigging bids to buy oil and gas leases in northwest Oklahoma from December 2007 to March 2012, according to the U.S. Department of Justice.

According to the Justice Department, he led a scheme conspiracy between two large energy companies, deciding ahead of time which one would win the bids. The winner would then allocate part of the leases to the other company.

McClendon's indictment is "the first case resulting from an ongoing federal antitrust investigation into price fixing, bid rigging and other anticompetitive conduct in the oil and natural gas industry," according to the Justice Department.

"His actions put company profits ahead of the interests of leaseholders entitled to competitive bids for oil and gas rights on their land. Executives who abuse their positions as leaders of major corporations to organize criminal activity must be held accountable for their actions," said Assistant Attorney General Bill Baer of the Justice Department's Antitrust Division.

McClendon denied any wrongdoing in a statement Tuesday and said he was "proud" of his industry record and would fight the charges.
