Man kills roommate with AR-15 style gun after ‘cool down’ from fight, PA cops say
Two roommates got into a fight about their living arrangements when things turned physical, then deadly, Pennsylvania police said.
The fight started the night of June 6 when Timothy Pirraglia got home from work, Sandy Township police said. He knocked Christopher Euard, his roommate of one year, to the ground and pushed him into the corner, according to a probable cause affidavit filed June 7.
The two went into their separate bedrooms, Euard told police. During the “cool down” period, Pirraglia decided he wanted to leave the home.
With a backpack on, Pirraglia left his room to leave but was confronted by Euard. Police said he was holding an AR-15 style firearm, the affidavit said.
A third roommate, who was also trying to leave, overheard the two arguing in the hallway when Pirraglia yelled, “Do it. You’re not going to do it,” the affidavit said.
Euard fired one shot, which fatally struck the man in the chest, according to the affidavit.
With Pirraglia dead in the hallway, Euard turned to his other roommate.
“He’s down,” Euard said, according to court documents.
“What do you mean he’s down?” the third roommate replied.
“You know what happened,” Euard said back.
“I just want to leave. I don’t want any part of this, why would you put me in this situation? I don’t know what to do, what do I do?” the roommate said, then left the residence.
Euard said he “passed out,” then called police the next morning at about 3 a.m., the affidavit said.
Euard was charged with criminal homicide, aggravated assault and recklessly endangering another person, according to court records.
Sandy Township is about a 100-mile drive northwest from Pittsburgh.
