LOS ANGELES — The Porsche carrying "Fast & Furious" star Paul Walker was traveling up to 94 mph (151 kph) when it went out of control on a suburban street and crashed, killing the actor and his friend, according to an investigation by law enforcement agencies into the November accident. The sports car driven by Roger Rodas slammed into a light pole with a 45 mph (72 kph) speed limit sign and burst into flames. Walker and Rodas died at the scene. Investigators with the Los Angeles County Sheriff's Department and California Highway Patrol concluded that unsafe speed, not mechanical problems, caused the Nov. 30 crash, the sheriff's department said Tuesday. Based on post-crash calculations, accident reconstruction specialists with the Highway Patrol believe Rodas was driving his 2005 Porsche Carrera GT between 81 mph (130 kph) and 94 mph (151 kph), according to their investigative report. The CHP declined comment. The Associated Press reported in December that investigators had found no evidence that the car had mechanical problems and had ruled out debris or other roadway conditions. — AP
