Alcohol is suspected to have played a part in the Monday death. Dunn tweeted a photo of himself and another man drinking at Barnaby's of America's bar just hours prior.
The Chester County coroner listed blunt force trauma and thermal trauma as the official causes of death for both men. But the definitive answer will take over six weeks as toxicology results return to the labs.
A preliminary examination of the crash site suggested that Dunn's Porsche might have been traveling more than 100 mph in the 55 mph zone when it jumped a guardrail and struck a tree and burst into flames.
