Oklahoma’s chief medical examiner determined that Aubrey McClendon’s death was an accident when his Chevy Tahoe ran off the road March 2 and slammed into a wall.

McClendon’s blood tested negative for alcohol, according to a report Wednesday signed by Marc Harrison, a pathologist with the state medical examiner. Doxylamine, an over-the-counter antihistamine, was detected but not confirmed in his liver. A test for carbon monoxide was negative. The medical examiner in March said the Chesapeake Energy Corp. co-founder died from wounds caused by multiple blunt force trauma.
