Authorities: 2nd man cleared in Giffords shooting
Arizona authorities say a second man has been cleared of any involvement in an attempted assassination of US Rep. Gabrielle Giffords in Tucson.
Pima County Sheriff's Deputy Jason Ogan said Sunday that the man was a cab driver who drove the gunman to the grocery store outside of which the shooting occurred. Ogan says the man went into the store because the gunman apparently hadn't paid his fare. (AP)
