The Chester County Coroner's office on Tuesday confirmed that both Ryan Dunn and his passenger died from the impact of a crash and the fire that engulfed the 2007 Porsche he was driving early Monday morning.

The Chester County coroner said blunt force trauma and thermal trauma were the causes of death for both victims, according to the Associated Press.

Police said that speed may have been a factor for the fatal crash throwing Dunn's Porsche off the road crashing into some trees and bursting in flames.

In an emailed statement to the AP Dunn's brother Eric Dunn shares:

We appreciate the support of Ryan's fans during this time, and we are grateful for your thoughts and prayers. Ryan will be greatly missed, but he will forever remain in our hearts.
