Paul Walker Porsche Crash Down To 'Speed Alone'
The Porsche Carrera GT that crashed killing Fast & Furious actor Paul Walker and the driver had no mechanical problems, according to investigators.
A police official, speaking on condition of anonymity, said the car lost control due to "speed, and speed alone".
The investigation also ruled out debris in the road as causing the car in which Walker was a passenger to smash into a street light and a tree.
The actor and the driver, his friend and financial adviser Roger Rodas, were both killed in the accident on November 30.
Investigators have refused to set a firm speed at which they think the car was travelling until Porsche engineers come to California next month to extract information from on-board data collectors.
According to reports in the US, three black boxes have been recovered from the vehicle.
One will be able to tell the last speed recorded and whether the airbags were deployed, while the other two will give information on the throttle and engine readings.
As a result of 40-year-old Walker's death, Universal Pictures has announced it is putting the filming of Fast & Furious 7 on hold indefinitely.
More than half the movie has reportedly been made and it was slated for release on July 11, 2014.
