Killer of 2 NY Firemen Had Semiautomatic Rifle Police say the man who lured firefighters in Webster, N.Y., into a deadly ambush had the same make and caliber semiautomatic rifle as the one used in the Connecticut school massacre. Webster Police Chief Gerald Pickering said Tuesday that 62-year-old William Spengler was armed with a .223-caliber Bushmaster rifle, a .38-caliber revolver and a 12-gauge shotgun in Monday's ambush. Spengler killed two firefighters and wounded two others before fatally shooting himself. Police have not said which weapon or weapons were used to shoot the firefighters. Spengler, who set his house on fire to lure the first responders, left a note saying he wanted to burn down the neighborhood and kill as many people as possible. But the note didn't give a motive for the shooting.
