YORK, Pa. — On Wednesday afternoon, three police officers were killed, and two others were injured in a shooting in North Codorus Township, York County.
The officers were killed Wednesday while following up on a domestic-related investigation that began on Tuesday. Two more officers were wounded in the shooting and police killed the gunman.
What we know about the shooter:
The man who fatally shot three Pennsylvania officers and injured two before he was killed by police has been identified as 24-year-old Matthew James Ruth, according to a law enforcement official.
The official spoke on condition of anonymity to the Associate Press because they weren’t authorized to discuss an ongoing investigation.
On Tuesday, Sept. 16, a woman observed Ruth stalking the house in a cornfield close by, and notified authorities, according to a criminal complaint obtained by FOX43.
The woman reported the incident to the Northern York County Regional Police Department to obtain an arrest warrant and a restraining order.Â
Officials attempted to serve the shooter with the warrant on Tuesday night but were unable to find him, law enforcement said.
Officers with the NYCRPD returned to the house to do a follow-up visit on Wednesday, which was when the shooter opened fire from a nearby cornfield. Three officers from the NYCRPD were killed.Â
The shooter then allegedly began moving toward the house where he exchanged gunfire with three York County Sheriff’s. Two of the York County Sheriffs were struck and injured, but one returned fire and killed the shooter, according to officials.
Police documents said that the shooter allegedly wore camouflage, and it is not yet clear to investigators whether the shooter waited in the cornfield for the ex-girlfriend or the arresting officers.
