Investigators say they are focusing on speed in the crash that killed "The Fast and the Furious" star Paul Walker. He was in the passenger seat and his race team partner Roger Rodas was behind the wheel. But were they racing at the time of the crash? Kyung Lah has the latest.

Anderson discussed all of this with Eddie Alterman, Editor-In-Chief of “Car and Driver” magazine.
