Three Pennsylvania officers killed in York County ambush identified; investigation expands
Authorities name the fallen, provide new details as federal, state and local agencies assist in the inquiry into the domestic-violence-linked shooting.
Three Pennsylvania police officers were identified as the victims of an ambush in York County on Wednesday, authorities said, as investigators provided new details about the attack and the man who unleashed it. Sgt. Cody Becker, Detective Mark Baker, and Detective Isaiah Emenheiser of the Northern York County Regional Police Department were killed after they and other officers responded to a domestic-call scene in North Codorus Township. A second Northern York County Regional Police detective and a York County Sheriff's Office deputy were critically wounded but remained in stable condition, according to York County District Attorney Tim Barker. The suspected gunman, 24-year-old Matthew James Ruth, was killed by police following a final confrontation near the road. Barker noted that Ruth did not have any prior criminal convictions on record.
The investigation began Tuesday night after Ruth’s ex-girlfriend’s mother reported seeing him on her property in camouflage and looking into the home with binoculars. Trail-camera footage showed Ruth armed with an AR-15–style rifle, and his truck was left nearby. The ex-girlfriend also told investigators her pickup truck had been set on fire in August, though she could not confirm whether Ruth was responsible, and she requested investigators not pursue it at the time. Detectives returned to the empty home just after 2 p.m. Wednesday, and as they walked through the unlocked front door, the suspect opened fire with suppressed rounds, Barker said. Ruth was later killed in a final shootout near the road. Inside the house, investigators recovered shell casings from the initial ambush and, in the basement, the body of the ex-girlfriend’s mother’s black Labrador, which the suspect had shot and killed.
Authorities said the motive is still under review, but Barker stressed that domestic violence lies at the root of the tragedy. “All actions by law enforcement were justified. They weren't only justified, they were necessary,” Barker said. “We are so thankful and appreciative to them, and especially our northern York County Regional detective who fired the last shot and who rendered aid. I can't imagine the strength and the fortitude that it takes to immediately, after having seen and been engaged in that … immediately thinking of rendering critical aid.” He added, “He saved many lives that day. If the actor was not eliminated, and his threat and murderous rampage eliminated, who knows where this would have stopped.”
Before the shooting, Ruth had been charged with stalking, trespassing, loitering and prowling at night in relation to the investigation, court documents show. The FBI, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), and the Pennsylvania State Police are assisting local authorities. Attorney General Pam Bondi said the federal government would offer full support.
The shooting occurred about 115 miles west of Philadelphia in North Codorus Township, a reminder that York County has faced fatal violence involving law enforcement in recent months. Pennsylvania Gov. Josh Shapiro said he was praying for everyone involved during a news conference, calling the day absolutely tragic and devastating for the county, the commonwealth and the country. Shapiro said the state would continue to support those affected and ensure responders receive any needed resources. The Associated Press contributed to this report.
Images from the scene and a related procession captured the scale of the response to a tragedy that unfolded in a quiet county.
As the investigation continues, authorities are reviewing security footage, cell data and other evidence to determine how the suspect acquired the AR-15–style rifle and whether any additional individuals were involved. York County officials said additional briefings and possible updates would be provided as more information becomes available.
The community and law enforcement partners are bracing for a somber period of reflection and continued investigation, including the role of domestic violence in acts of violence against officers. Processions and memorials are expected in the days ahead as York County honors Becker, Baker and Emenheiser.
