Paul Walker Crash Caused By 'Unsafe Speed'
The car crash that killed actor Paul Walker was caused by excessive speed and not mechanical problems.
The Los Angeles County Sheriff's department came to its conclusion after a four-month investigation into the accident that killed the Fast & Furious star and his friend Roger Rodas.
Mr Rodas was driving the red Porsche Carrera GT at speeds of 80 to 93mph (129 to 150kph) before he lost control of the car, the investigation found.
The 38-year-old crashed into trees and a pole with a 45mph (72kph) speed limit sign on it in a suburban street in Santa Clarita, California, northwest of Los Angeles.
"Investigators determined the cause of the fatal solo-vehicle collision was unsafe speed for the roadway conditions," said Commander Mike Parker.
The conclusion about the speed was based on a skid mark that one of the car's tyres left on the road.
An unidentified witness said she saw the Porsche "jiggling back and forth in (its) lane like the driver was jiggling the steering" just before the crash, according to the report.
A coroner's report released earlier this year found the car could have been travelling at 100mph.
The LA sheriff's investigation also found both men had been wearing seatbelts, and both the driver's and passenger's airbags had deployed.
After the crash, Porsche sent engineers to California to review the rare car's wreckage. They found no problems with the vehicle.
Walker, 40, died from traumatic injuries and burns in the November 30 crash.
Mr Rodas, who was Walker's financial adviser, died of multiple traumatic injuries.
Post-mortems showed neither man had alcohol or drugs in their systems.
When he died, Walker was filming Fast & Furious 7. The movie's release has been pushed back to April 2015, but it will still feature Walker.
