The Clay County Coroner's Office identifies the victim as 76 year old Mary Franklin of Lake Como, New Jersey.
Dr. Roland Kohr determined Franklin died of blunt force trauma prior to her vehicle catching fire.
The accident happened at 1:21 Sunday morning in the westbound lanes of I-70 near the 25 mile marker.
