The car then rolled several times before coming to rest on its top, with the man pinned beneath the wreckage, Duteil said.
Careflight was dispatched, but the victim was pronounced dead at the scene by the Preble County coroner, Duteil said.
An eyewitness told News Center 7 and whiotv.com the small compact car was upside down in a ditch near a culvert, and as many as 18 rescue personnel were trying to get the victim out of the wreckage.
