Shooter Who Killed 3 Cops in Pennsylvania Identified

Authorities have identified the gunman responsible for a deadly ambush that resulted in the deaths of three Pennsylvania police officers and injuries to two others as 24-year-old Matthew James Ruth of Hanover.

The killings occurred around 2:10 pm on Wednesday in North Codorus Township, while officers were attempting to serve a warrant related to Ruth stalking a female he had briefly dated.

Prosecutors had charged Ruth shortly before the ambush with stalking, prowling at nighttime, and criminal trespass, according to court records. Police returned to the scene on Wednesday to serve the warrant as part of their investigation, but were met with heavy fire.

According to York County District Attorney Dave Sunday, Ruth had concealed himself in the girl's home, lying in wait to ambush the officers when they arrived. Neighbors reported hearing at least 30 rounds of gunshots. The girl Ruth briefly dated said she had never invited him over to her house, police said.

Ruth fatally wounded three detectives, identified as Sgt. Cody Becker, Mark Baker, and Isaiah Emenheiser. Two additional officers—a sheriff's deputy and another detective—were injured but survived, with one in critical condition.
