WEBSTER, N.Y. (AP) — The ex-convict-turned-sniper who killed two firefighters wanted to make sure his goodbye note was legible, typing out his desire to “do what I like doing best, killing people” before setting the house where he lived with his sister ablaze, police said.

Police Chief Gerald Pickering said Tuesday that the 62-year-old loner, William Spengler, brought plenty of ammunition with him for three weapons, including a military-style assault rifle, as he set out on a quest to burn down his neighborhood just before sunrise on Christmas Eve.

And when firefighters arrived to stop him, he unleashed a torrent of bullets, shattering the windshield of the fire truck that volunteer firefighter and police Lt. Michael Chiapperini, 43, drove to the scene. Fellow firefighter Tomasz Kaczowka, 19, who worked as a 911 dispatcher, was killed as well.

Two other firefighters were struck by bullets, one in the pelvis and the other in the chest and knee. They remained hospitalized in stable condition and were expected to survive.

On Tuesday, investigators found a body in the Spengler home, presumably that of the sister whom a neighbor said Mr. Spengler hated: 67-year-old Cheryl Spengler. Spengler’s penchant for death had surfaced before. He served 17 years in prison for manslaughter in the 1980 hammer slaying of his grandmother.

But his intent was unmistakable when he left his flaming home carrying a pump-action shotgun, a .38-caliber revolver and a .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.

“He was equipped to go to war, kill innocent people,” the chief said of a felon who wasn’t allowed to possess weapons because of his criminal past. It was not clear how he got them.

The assault rifle was believed to be the weapon that struck down the firefighters. He then killed himself as seven houses burned on a sliver of land along Lake Ontario. His body was not found on a nearby beach until hours afterward.

Residents of the suburban Rochester neighborhood who left their homes during the fire were allowed to return Tuesday. Police SWAT team members used an armored vehicle to evacuate more than 30 residents during the incident.

Spengler’s motive was left unclear, Chief Pickering said, even as authorities began analyzing a two- to three-page typewritten rambling note Spengler left behind.

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.”

Chief Pickering added, “There was some rambling in there and some intelligence we need to follow up on.”

It remained unknown what set Spengler off, but a next-door neighbor, Roger Vercruysse, noted that he loved his mother, Arline, who died in October after living in the house in a neighborhood of seasonal and year-round homes across the road from a lakeshore popular with recreational boaters.

Chief Pickering said it was unclear whether the person believed to be Spengler’s sister died before or during the fire.

“It was a raging inferno in there,” Chief Pickering said.
