A new police report has revealed the cause of the fatal car crash that killed Paul Walker and his friend Roger Rodas.
The Los Angeles County Sheriff's traffic collision experts have determined that the speed of the car, which was said to be between 80 and 93 mph, was the reason for the accident.
"Investigators determined the cause of the fatal solo-vehicle collision was unsafe speed for the roadway conditions," Commander Mike Parker explained.
"During the examination, it was determined that an aftermarket exhaust system had been installed which would have increased the engine's horsepower."
The California Highway Patrol's Multi-disciplinary Accident Investigation Team conducted an exhaustive examination on the 2005 Porsche Carrera GT involved in the crash, including its history, safety recalls and repair records.
