When a Freeport man refused to lower the weapon he was holding, and then fired it at a responding Monroeville police officer Monday night, the officer shot back six times.
Paul J. Slimick, 26, died from a gunshot wound to the head a short time later at Forbes Regional Hospital, according to the Allegheny County medical examiner's office.
According to Allegheny County police Lt. Andrew Schurman, Mr. Slimick showed up at the house in the 200 block of East Patty Lane about 10 p.m., looking for the man who lived there and who was dating his ex-girlfriend.
"He shows up at the house threatening the new boyfriend," Lt. Schurman said.
The resident was able to sneak out of the house through the basement and call 911 to report a burglary in progress. The man did not know his attacker, the lieutenant said.
When the first Monroeville officer arrived on the scene, he encountered Mr. Slimick leaving the house.
"That male had a handgun and did not comply with the officer's directions, but rather fired at the officer," a county police news release states. "The officer returned fire, striking the man."
Lt. Schurman said the officer, whose name has not been released, fired at Mr. Slimick from about 35 feet away.
The officer was not struck during the exchange of gunfire.
Following Monroeville's protocol, the officer, who does not have any history of previous shootings, was placed on administrative leave, Lt. Schurman said.
Mike Manko, a spokesman with the Allegheny County district attorney's office, said, "We've been briefed on the matter and have discussed with county police what steps we would like them to take to complete the investigation."
Lt. Schurman said that investigators are awaiting the autopsy and ballistics results before completing their work.
"It's pretty straightforward."
Mr. Slimick had only one previous criminal conviction -- for driving under the influence in Westmoreland County in 2008 -- and the lieutenant said he was unaware of any previous problems with his ex-girlfriend.
