TUCSON, Ariz. (AP) — Arizona authorities say the gunman accused of shooting an Arizona congresswoman and killing six others acted alone.
Pima County Sheriff Clarence Dupnik says Sunday that there is no evidence that anybody besides 22-year-old suspect Jared Loughner (LAWF’-ner) was involved.
Authorities earlier cleared a suspected accomplice, a cab driver, of involvement.
Dupnik says the cab driver walked into the Tucson Safeway store with Loughner because the driver didn’t have change for a $20. He says the shooting occurred just after the two exchanged money.
