ST LOUIS (LALATE) – The Ryan Dunn autopsy report results were released partially by the Chester County Coroner’s Office to news Tuesday. Ryan Dunn and Zachary Hartwell reportedly died from a blunt force trauma and resulting fire, the Coroner’s initial autopsy report ruled Tuesday. The cause of the car crash (photos below) remains under investigation. But the Chester County Coroner’s Office ruled that no medical event preceding the crash had occurred for either Dunn or Hartwell.
The Coroner’s Office final autopsy report could take four to six weeks pending toxicology tests. But on Tuesday, Chester County ruled initially that the impact of the crash, and the resulting fire, both took the lives of Ryan Dunn and Zachary Hartwell. The Office would not rule initially if Dunn and Hartwell were dead on impact. Rather it ruled that the fire was a possible contributing cause of death.
The Office did not detail to news today the conditions of the crash scene from which it based its report. As previously revealed, Chester County police officials were only able to identify Dunn after the crash by his tattoos. Today the Coroner’s Office stated that both men were dead by the time emergency response officials were at the crash site.
Ryan Dunn and Zachary Hartwell had left a local drinking establishment in the early morning hours of Monday morning. Dunn was the wheel of his supercharged Porsche, Hartwell was his passenger. Hartwell was Dunn’s production assistant on the movie “Jackass Number Two.” Funeral arrangements have not been announced.
Police have previously confirmed that Dunn went off the four-lane highway, hit a right guardrail, and crumpled the structural membrane of the rail. The impact of the car crash sent the Porsche into trees or brush off the road. Upon impact the Porsche burst into flames. Virtually no recognizable structure of a vehicle was visible when emergency response arrived.
On Monday, police said that Ryan Dunn had been travelling at a heightened speed. Beyond that, officials have yet to conclude the cause(s) of the crash; they have yet to indicate how long their investigation will take.
