William Spengler, 62, who served 17 years in prison for manslaughter in the 1980 hammer slaying of his grandmother, set his house afire before dawn Christmas Eve before taking a revolver, a shotgun and a semiautomatic rifle to a sniper position outside, Police Chief Gerald Pickering said.
The death toll rose to three as police revealed that a body believed to be the killer’s 67-year-old sister, Cheryl Spengler, was found in his fire-ravaged home.
Authorities say he sprayed bullets at the first responders, killing two firefighters and injuring two others who remained hospitalized Tuesday in stable condition, awake and alert and expected to survive. He then killed himself as seven houses burned on a sliver of land along Lake Ontario.
Police recovered a military-style .223-caliber semiautomatic Bushmaster rifle with flash suppression, the same make and caliber weapon used in the elementary school massacre in Newtown, Conn., that killed 26, including 20 young children, Pickering said.
The chief said it was believed the firefighters were hit with shots from the rifle given the distance but the investigation was incomplete.
“He was equipped to go to war, kill innocent people,” the chief said.
The two- to three-page typewritten rambling note left by Spengler did not reveal what set off the killer or provide a motive for the shootings, Pickering said. He called the attack a “clear ambush on first responders.”
He declined to reveal the note’s full content or say where it was found. He read only one chilling line: “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.”
