ROCHESTER, N.Y. (AP) — A New York woman was sentenced to eight years in federal prison Wednesday for supplying guns to a former neighbor who used them to kill his sister and two firefighters in a Christmas Eve ambush that also caused seven homes to burn to the ground. Prosecutors said Nguyen accepted $1,000 from Spengler to go with him to a Gander Mountain store in June 2010 and buy a semi-automatic rifle and pistol-grip shotgun, lying on a form that they were for her.
