An energy tycoon who died in a car crash the day after his indictment by a federal grand jury was traveling well over the speed limit when he struck a bridge abutment, Reuters reports. Aubrey McClendon, former CEO of Chesapeake Energy, hit 88mph in a 50mph zone just a few seconds before the March 2 crash in Oklahoma City, according to black-box data in his wrecked Chevy Tahoe, police tell KFOR. He also went left of the center lane 189 feet before the crash, and tapped the brakes twice but didn't appear to slow down much; impact occurred at 78 mph, police say. He wasn't wearing a seatbelt, but Oklahoma City Police Chief Bill Citty says that "made absolutely no difference." McClendon had been indicted over alleged bid rigging. (More car crash stories.)
