“Webster Police Chief Gerald Pickering said Tuesday that 62-year-old William Spengler was [illegally] armed with a .223-caliber Bushmaster rifle, a .38-caliber revolver and a 12-gauge shotgun in Monday’s ambush,” huffingtonpost.com reports. “Spengler killed two firefighters and wounded two others before fatally shooting himself.” Crucially, perhaps, “Police have not said which weapon or weapons were used to shoot the firefighters.” That said Pickering told the press it was “likely” the killer used the Bushmaster. At the moment, the mainstream media has focused its main attention on Spengler’s suicide note which read (in part): “I still have to get ready to see how much of the neighborhood I can burn down and do what I like doing best – killing people.” In 1981, Spengler pleaded guilty to manslaughter for bludgeoning his 92-year-old grandmother to death with a hammer. He was imprisoned until 1998. Supervised parole expired in 2006.
