Joshua Fryman, 23, reportedly died from blunt force trauma injuries after being flown to UK Hospital.
Officials are ruling the death as accidental.
At last report, the driver of the car was in critical condition.
Cynthiana and Harrison County firefighters said they arrived at the scene of the accident on Highway 36 West and Hendricks Road at around 1:30.
There, they said they found the car on fire in the middle of a field and two men lying unconscious nearby.
Harrison County Sheriff Bruce Hampton believes the driver lost control of the car, causing it to go off the road, catch fire and roll multiple times before coming to rest a few hundred yards away.
"[The car] went down over an embankment on the right-hand side of the roadway, through a telephone pole then through a fence, across the [another] roadway then up a little embankment and through another fence," Hampton said.
He believed both victims were ejected at one point during the wreck.
According to Hampton, both victims, believed to be in their early 20’s, suffered head injuries and one victim also had burns from the fire.
Hampton said the cause of the crash is still under investigation but speed was a likely factor.
