Coliseum Health CEO Allen Golson died from smoke inhalation and thermal burns.
That's according to Jenifer Lowe with the Marion County, Florida Sheriff's Office.
Golson's plane crashed near the Ocala International Airport Friday.
The District 5 Medical Examiner's office conducted the autopsy.
The incident report from the Marion County Sheriff's office says several people witnessed the plane go down.
It details that an officer contacted Golson's family at his wife, Carol's, request. She was injured in the crash.
The report says witnesses helped get Carol out of the burning plane.
In a statement with officers, Carol told them her husband was conscious and talking after after the crash.
When officer met her for interviews at the hospital, she was reportedly suffering of back pain.
A medic who responded to the scene said he heard screaming and other noises from the plane, which was fully involved at that time, but he said he could not find the pilot.
One officer says in his report he noticed a debris field to the east of the location. He says the left wing was partially separated from the fuselage. The nose of the aircraft appeared to have the majority of the damage.
Surveillance video from a nearby business recorded the crash.
The report says there were four transmissions from the control tower with the aircraft, and no indications of an emergency.
Lead investigator with the National Transportation Safety Board Ralph Hicks says at this point they're not ruling out anything as a cause of the crash.
He says the autopsy results will be used in their investigation, as well as air traffic reports and radar information.
Hicks says their preliminary findings on the crash will be released later this week, but it could take three to four months until the investigation is competed.
