A rural southern Pennsylvania community was mourning the deaths of three law enforcement officers on Sept. 18 after a shooting broke out during a domestic-related investigation one day earlier.

Authorities are expected to give more information on the shooting standoff that killed the three officers and left two others wounded at a news conference later in the day. A suspect was also killed by police at the scene on Sept. 17. Neither the victims nor the suspected shooter have been identified.

The day before the shooting, authorities responded to the same home where the shooting broke out to a report of a stalking incident, according to records obtained by the York Daily Record, part of the USA TODAY Network.

The shooting broke out in North Codorus Township, which has a population of just over 9,000 people and sits in York County, Pennsylvania. The evening of Sept. 17, police and emergency vehicles escorted the bodies of the fallen officers to the county coroner's office in a procession as hundreds lined the streets to pay their respects, reported the York Daily Record. A vigil is planned for the evening of Sept. 18 at a church in neighboring Spring Grove, Pennsylvania.

"These officers represent the very best of us. They put their lives on the line to serve their community, their Commonwealth, and their country," Pennsylvania Gov. Josh Shapiro said. "The prayers of 13 million Pennsylvanians are with the victims, their families, and the good people of York County on this devastating day – and all those who put on the uniform to keep our Commonwealth safe."

Records reveal stalking report for man seen at York County home

The day before the shooting, officers responded to the same home where the shooting happened for a report of alleged stalking. They charged a Hanover man for misdemeanor stalking, prowling at nighttime and summary criminal trespass, according to the records obtained by the York Daily Record.

In an affidavit of probable cause, officers wrote that they were called to the home on the 1800 block of Haar Road in North Codorus Township at about 11:24 p.m. on Tuesday, Sept. 16, 2025, for a resident reporting a white male wearing camouflage was on her property and was looking into the residence with binoculars. Officers were unable to locate the man that day, the records said.

Investigators spoke with the resident's daughter, who told them that on Aug. 20, 2025, someone set her pick-up truck on fire while it was sitting in the home's driveway, according to the affidavit. She said she believed her ex-boyfriend had done it, and also identified the ex in footage from a trail camera on the property as the same man who was at the home on Sept. 16.

Officers noted in the affidavit that in images captured on the night of Sept. 16, the man "had an AR-15 style rifle slung across the chest while looking into the residence."

What happened in the Pennsylvania shooting?

Authorities haven't released details about the incident that led to the shooting on Sept. 17. According to Pennsylvania State Police Commissioner Christopher Paris, officers were following up on an investigation that was domestic-related.

The first call about the shooting came in to a 911 call center in York County at about 2:10 p.m., officials said. The shooting prompted a large response from local, state and federal agencies to the 1800 block of Haar Road.

Paris said the shooter died after being shot by police, and there was no ongoing threat to the community.

Two injured in critical condition

The two wounded officers, whose identities have not been released, were in critical but stable condition and were being treated at WellSpan York Hospital, Paris said at a news conference on Sept. 17.

Not much is known about the officers killed and wounded, but York City Mayor Michael Helfrich said in a statement that Northern Regional Police Officers and York County Sheriff's Office were involved in the incident.

Hostile gunfire: How many police officers have been killed in the line of duty in 2025?

In all, 65 officers have fallen in the line of duty this year, according to the Officer Down Memorial Page — including 37 killed by hostile gunfire or physical or vehicular assault. Others died as the result of explosions, accidents, job-related illness or other factors.

Nearly 170 officers died in the line of duty in 2024, the site reported.
