A post-mortem examination has found that neither Paul Walker nor driver Roger Rodas were under the influence of drugs or alcohol at the time of their deaths in the fatal car accident.
Their Porsche was travelling at an “unsafe speed” when it hit a pole and burst into flames in California on November 30, a coroner’s report stated.
Both deaths have since been ruled accidents, authorities say.
Paul Walker was best known for the car racing films Fast and Furious.
Authorities estimate the car was travelling at nearly 100 mph at the time of the fatal accident, according to the coroner’s report released on Friday.
But sheriff’s officials say the investigation into the accident has yet to be completed.
A previous post-mortem examination determined Paul Walker, 40, was killed by impact and injuries related to a fire.
The Los Angeles County coroner found that the driver, Roger Rodas, died from impact injuries alone.
Both men are said to have died within seconds of the crash, according to media reports.
Paul Walker starred in the Fast & Furious blockbuster films that celebrated high-speed car chases.
Production on the seventh installment of the Fast and Furious franchise was temporarily halted following his death.Universal Pictures later announced the film’s release date would be pushed back several months to April 2015.
