Los Angeles County Sheriff's Department crash investigators have determined that the Porsche carrying "Fast & Furious" star Paul Walker was traveling between 80 and 94 miles per hour when it lost control on a Santa Clarita street and smashed into a power pole and several trees, killing the actor and his friend.
The speed limit where the collision occurred is 45 miles per hour.
The report concludes that unsafe driving, not mechanical problems, caused the crash, though the tires were more than nine years old. The Department said in a news release that a mechanical examination revealed no pre-existing problems that would have led to the crash.
"Investigators determined the cause of the fatal solo-vehicle collision was unsafe speed for the roadway conditions," Sheriff's Commander Mike Parker said in a news release.
Evidence indicates that both Walker and Rodas were wearing seatbelts, and that their airbags deployed, according to the Department. Toxicology tests were also negative for alcohol and drugs.
The report says driver Roger Rodas was going between 80 mph and 94 mph on the afternoon of Saturday, Nov. 30 when his 2005 Porsche Carrera GT began to drift as it lost control after coming out of a curve. The car had been upgraded to increase the engine's horsepower, according to the Sheriff's Department.
The Los Angeles County Sheriff's Department and California Highway Patrol did the investigation.
