Officials on Thursday identified the three police officers that were killed when they were ambushed while responding to a domestic call Wednesday in York County, Pennsylvania.

The fallen included Northern York County Regional Police Department’s Sgt. Cody Becker, Detective Mark Baker and Detective Isaiah Emenheiser, according to York County District Attorney Tim Barker.

Another Northern York County Regional Police detective and a York County Sheriff’s Office deputy were critically wounded, but remain stable at the hospital, Barker said.

The suspected gunman, identified as Matthew James Ruth, 24, was killed by police, officials said. He did not have any prior criminal convictions.

“He saved many lives that day,” he added. “If the actor was not eliminated, and his threat and murderous rampage eliminated, who knows where this would have stopped.”

Prior to the shooting, Ruth was charged with stalking, trespassing, loitering and prowling at night in relation to the investigation, court documents show. 

The FBI, Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), and the Pennsylvania State Police are assisting local authorities. Attorney General Pam Bondi offered the full support of the federal government.
