Paul Walker Crash: 'Speed Alone' Looks to Be Factor

Looks like there may not be anything to blame in the crash that killed Paul Walker other than how fast he and driver Roger Rodas were going. Investigators found no evidence of mechanical problems with the Porsche, and have also ruled out debris and roadway conditions as possible factors. "We're looking at speed and speed alone," a law enforcement official tells the AP. Investigators have figured out a range of speed the car was likely traveling at the time, but they haven't released that information yet. Porsche engineers will be assisting in the investigation next month.

A curve in the road near the crash site was also not to blame, the AP's source says, as the Porsche appeared to negotiate that curve with no problems. "They were well out of the curve when they lost control," he says. But multiple law enforcement sources tell TMZ that the AP's entire report is false, and that investigators actually have not made any determinations regarding the cause of the accident yet.
