Speed to Blame for Paul Walker's Death

Reports from the California Highway Patrol show speed, not mechanical problems, was the main cause of the car accident that killed Fast and Furious star Paul Walker.

Walker was in the passenger seat of a Porche, driven by his friend, when the car slammed into a light pole and burst into flames.

Investigators said they were driving between 80 and 93 miles per hour. Toxicology reports show neither of the men had alcohol or drugs in their system.
