NORTH CODORUS TOWNSHIP, Pa. — Law enforcement were investigating Thursday after a shooting killed three officers and wounded two more in southern Pennsylvania the day before.

The violence erupted in rural York County as officers followed up on a domestic-related investigation that began on Tuesday.

Drone video shows the farmhouse in North Codorus Township, where the ambush took place.

Authorities have not yet released the identities of the three officers who were killed.

Officials said police killed the shooter and that there is not any threat to the community.

The two injured officers were in critical but stable condition at York Hospital, authorities said.

The officers were following up on an investigation that began on Tuesday, according to Paris, who characterized the case as “domestic-related.”

Hours after the violence, community members held American flags and saluted as police and emergency vehicles formed a procession to the coroner’s office.

Gov. Josh Shapiro condemned the violence at a news conference and said it was a tragic loss of life. Attorney General Pamela Bondi called the violence against police “a scourge on our society.”

It was one of the deadliest days for Pennsylvania police this century. In 2009, three Pittsburgh officers responding to a domestic disturbance were ambushed and shot to death by a man in a bulletproof vest.

Police departments across the region expressed condolences on social media. People were leaving flowers at the headquarters of the Northern York Regional Police Department.

The investigation into the shooting will cover multiple locations in York County, state police said in a statement.

Agents with the ATF Harrisburg Field Office and the FBI are assisting at the scene.

“Our prayers are with the officers, their families, and the entire York County community,” FBI Director Kash Patel said in a statement.

The incident was reported to 911 shortly after 2 p.m. on Wednesday and multiple police and emergency medical service units responded, a York County emergency management official said.

The shooting erupted in the area of North Codorus Township, about 115 miles (185 km) west of Philadelphia, not far from Maryland, authorities said.

Dirk Anderson heard “quite a few” shots from his home across the street from the shooting, he said. He saw a helicopter and police arrive.

The emergency response unfolded on a rural road in south-central Pennsylvania. Some 30 police vehicles blocked off roads bordered by a barn, a goat farm and soybean and corn fields.

Family members of those killed were grieving but proud of their loved ones, said Shapiro.

Another officer in the area was killed in February, when a man armed with a pistol and zip ties entered a hospital’s intensive care unit and took staff members hostage before a shootout that left both the man and an officer dead.
