Second Man Cleared in Giffords Shooting

The mysterious second man who was seemingly associated with Jared Loughner has been identified as a taxi driver who drove Loughner to the site of the shooting. Apparently he went into the grocery store near where the shootings occurred, where he was seen be a security camera, because Loughner failed to pay his fare. The man is not a suspect. So the shootings appear to be confirmed as the act of a lone nut.
