According to the report, Walker died of the combined effects of the traumatic and thermal injuries he sustained during a fiery crash Saturday meaning he did not die from the impact, but burned to death after his Porsche GT crashed into a tree and a pole and caught fire.
Rodas, who was driving the car, died from multiple traumatic injuries suffered upon impact. Burning was not listed as a factor in his death.
The Coroner added that the toxicology report for both men will be available in 6 to 8 weeks.
Walker, 40, and Rodas, 38, were identified using dental records as their body's were too badly burned to be distinguished after the incident.
