A .223 Bushmaster AR-15 assault rifle was used in the shooting
A 3-page note has been found with the remains of convicted killer William Spengler Jr., the man who set fire to his New York residence in order to kill firefighters in a Christmas Eve ambush.62-year-old Spengler fatally shot 2 firemen and wounded other two. 43-year-old Lt. Mike Chiapperini, along with young 911 dispatcher Tomasz Kaczowka were killed, International Business Times reports. A total of seven homes were engulfed in flames in the town of Webster, near Lake Ontario.
According to Webster Police Chief Gerald Pickering, the killer did not include details about his motives in the note.
"It spoke mainly that he intended to burn his neighborhood down and kill as many people as possible," Pickering tells the NY Post.
One chilling fragment of the typed suicide letter details that he intended to set the homes in his neighborhood ablaze and gun down as many emergency responders as he could.
"I still have to see how much of the neighborhood I can burn down and do what I like doing best: killing people," Spengler's note reads.
At around 6 a.m. on Christmas Eve, he reported a fire, waiting for firefighting crews to make an appearance. It is believed a .223 Bushmaster AR-15 assault rifle was used in the shooting. A 12-gauge shotgun and a .38 revolver, along with many 30-round magazines were also recovered at the scene.
"He was equipped to go to war, kill a lot of innocent people," Pickering describes.
As a convicted murderer, Spengler was not allowed to own any weapons. In 1980, he killed his grandmother, and served 17 years in prison for the crime.
His mother Arline recently passed away at 91, in October. In her obituary, she left instructions for all donations to be forwarded to the West Webster Firemen’s Association.
