Paul Walker's death certificate states that the combined effects of traumatic and thermal injuries were the reason behind the actor's death.
Therefore, this means that the late actor did not die from the impact of the crash alone but was also burned to death in the resulting fire, TMZ.com reported.
However 'The Fast and Furious' actor's friend Roger Rodas, who was driving the 2005 Porsche Carrera GT, died upon impact from multiple traumatic injuries.
According to the certificate, both men died quickly with the time period between the crash and their deaths determined as rapid.
