Medical Examiner report finds McClendon died of an accidental car crash $this->bbcode_second_pass_quote('', '[')b]Oklahoma City businessman Aubrey McClendon died of an accidental car crash, according to a medical examiner report released Wednesday.
The autopsy report listed the cause of death as multiple blunt force trauma to the torso and extremities due to motor vehicle collision.
The manner of death is listed as an accident.The toxicology report showed no evidence of alcohol or carbon monoxide in McClendon's blood. The report said doxylamine was detected, but not confirmed, in McClendon's liver. Doxylamine is an antihistamine found in some cold and allergy medication.
The medical examiner's report came one day after the Oklahoma City Police Department confirmed that its homicide investigation "found no information that would indicate anything other than a vehicular accident," police spokesman Capt. Paco Balderrama said Tuesday.
The police report was turned over to the medical examiner late last month, following a two-month investigation.
Co-founder of Chesapeake Energy Corp. and founder of American Energy Partners LP, McClendon died in a car crash March 2, one day after a federal grand jury indicted him on charges of conspiring to rig bids for oil and natural gas leases in northwest Oklahoma. Those charges were dismissed after the car crash.
The police completed their accident investigation two weeks after the crash. That investigation revealed McClendon's 2013 Chevrolet Tahoe was traveling 88 mph five seconds before the impact and that it hit the concrete wall at 78 mph. McClendon was not wearing a seat belt.
The vehicle veered left of center nearly 200 feet before crashing into the wall, the accident report stated. The vehicle's crash data box also revealed that McClendon tapped the brake pedal, but did not attempt to slow just before the crash, Oklahoma City Police Chief Bill Citty said in March.
