WEBSTER, N.Y. (AP) - A man who set his house on fire, then lured firefighters to their deaths in a blaze of flames and bullets, had attracted little attention since he got out of prison in the 1990s for killing his grandmother, authorities said.
But two months ago, William Spengler's mother died, leaving the 62-year-old ex-con in a Lake Ontario house with his sister, who he "couldn't stand," a friend said.
Spengler set a car and a house in his neighborhood ablaze early Monday, and then killed two responding firefighters, wounded two others and injured a police officer while several homes burned around him, police said. Spengler then killed himself. His sister, Cheryl, was missing.
Authorities did not offer a possible motive.
About 100 people attended an impromptu memorial vigil Monday evening in Webster, a suburb of Rochester. Dozens of bouquets were left at the fire station, along with a handwritten sign that said, "Thanks for protecting us. RIP."
Spengler had been living in the home in Webster, a suburb of Rochester, with his mother and sister since his parole in 1998. He had served 17 years in prison in the beating death of his 92-year-old grandmother in 1980, for which he had originally been charged with murder but pleaded guilty to a reduced charge of manslaughter. His mother, Arline, died in October.
On Monday, Spengler fired at the four firefighters when they arrived shortly after 5:30 a.m. at the blaze, town police Chief Gerald Pickering said. The first police officer who arrived chased the gunman and exchanged shots.
Spengler lay in wait outdoors for the firefighters' arrival, then opened fire probably with a rifle and from atop an earthen berm, Pickering said. "It does appear it was a trap," he said.
Authorities used an armored vehicle to help residents flee dozens of homes on the shore of Lake Ontario a day before Christmas. Police restricted access to the neighborhood, and officials said it was unclear whether there were other bodies in the seven houses left to burn.
Authorities said Spengler hadn't done anything to bring himself to their attention since his parole. As a convicted felon, he wasn't allowed to possess weapons. Monroe County District Attorney Sandra Doorley said Spengler led a very quiet life after he got out of prison.
A friend said Spengler hated his sister. Roger Vercruysse lived next door to Spengler and recalled a man who doted on his mother, whose obituary suggested contributions to the West Webster Fire Department.
"He loved his mama to death," said Vercruysse, who last saw his friend about six months ago.
Vercruysse also said Spengler "couldn't stand his sister" and "stayed on one side of the house and she stayed on the other."
The West Webster Fire District learned of the fire early Monday after a report of a car and house on fire on Lake Road, on a narrow peninsula where Irondequoit Bay meets Lake Ontario, Monroe County Sheriff Patrick O'Flynn said.
The fire appeared from a distance as a pulsating ball of flame glowing against the early morning sky, flames licking into treetops and reflecting on the water, with huge bursts of smoke billowing away in a brisk wind.
Emergency radio communications capture someone saying he "could see the muzzle flash coming at me" as Spengler carried out his ambush. The audio posted on the website RadioReference.com has someone reporting "firefighters are down" and saying "got to be rifle or shotgun - high powered ... semi or fully auto."
Two of the firefighters arrived on a fire engine and two in their own vehicles, Pickering said. After Spengler fired, one of the wounded men fled, but the other three couldn't because of flying gunfire.
The police officer who exchanged gunfire with Spengler "in all likelihood saved many lives," Pickering said.
A police armored vehicle was used to recover two men, and eventually it removed 33 people from nearby homes, the police chief said. The gunfire initially kept firefighters from battling the blazes.
The dead men were identified as police Lt. Michael Chiapperini, 43, the Webster Police Department's public information officer; and 19-year-old Tomasz Kaczowka, also a 911 dispatcher.
Pickering described Chiapperini as a "lifetime firefighter" with nearly 20 years in the department, and he called Kaczowka a "tremendous young man."
Kaczowka's brother, reached at the family home Monday night, said he didn't want to talk.
The two wounded firefighters, Joseph Hofstetter and Theodore Scardino, remained in guarded condition Tuesday at Strong Memorial Hospital, authorities said. Both were awake and alert and are expected to recover.
Hofstetter, also a full-timer with the Rochester Fire Department, was hit once in the pelvis, and the bullet lodged in his spine, authorities said. Scardino was hit in the chest and knee.
At West Webster Fire Station 1, there were at least 20 bouquets on a bench in front and a bouquet of roses with three gold-and-white ribbons saying, "May they rest in peace," ''In the line of duty" and
