Now officials claim Boston bombing suspect was NOT armed in boat showdown - despite police account of firefight and him 'shooting himself'

Two unnamed U.S. officials have told the Associated Press that the surviving suspect in the Boston bombings was unarmed when police captured him hiding inside a boat in a neighborhood back yard.
