Paul Walker died of extensive thermal injuries

The Fast and the Furious star Paul Walker suffered a car accident on November 30, 2013. He was driving his car alongside financier and racer Roger Rodas when he collided with a lamppost and two trees. His car immediately caught fire, and by the time firefighters arrived at the scene, both passengers were found dead.

Although initially, it was thought that Paul Walker died from the collision alone, the autopsy report from the Los Angeles County Coroner revealed that the actor actually died from extensive thermal injuries. The conclusion came from analyzing the carbonized skin and bone fractures that were related to overheating. 

Moreover, residue of carbon in Paul Walker’s trachea indicates that he was breathing for a moment after the fire had started, suggesting that he was still alive and died as a result of the thermal injuries.
