The coroner's report has been released from the fatal plane crash just outside of Fremont on June 8.
Former Ohio lawmaker Gene Damschroder was piloting the plane. He and his five passengers died.
Autopsies for all six victims show they died from blunt force trauma caused by the crash. The coroner says they were all dead before a fire started in the plane.
A final NTSB report on the cause of the crash is expected by the end of the year.
