Sniper's rifle tied to Alabama raid

The rifle used in the Washington area sniper shootings has been implicated in an Alabama robbery murder that led police to suspects John Allen Muhammad and John Lee Malvo.

Police said new tests suggested the gun used in the September 21 liquor store shooting was the rifle authorities found in Muhammad's Chevrolet Caprice.

They said a third person could have been involved in the Alabama robbery, possibly firing the Bushmaster rifle that was found when the sniper suspects were picked up.
