NORTH CODORUS, Pa. (AP) — A suspected stalker armed with a rifle hid at his ex-girlfriend’s home in the rolling farmland of southern Pennsylvania and ambushed police officers who came to arrest him, killing three of them, a prosecutor said Thursday.

Police arriving at the scene at about 2:10 p.m. Wednesday noticed the door to the home was unlocked even though the ex-girlfriend and her mother had locked it before leaving the property for their safety.

They opened the door and were immediately fired upon by the suspect, 24-year-old Matthew James Ruth, who was carrying an AR-style rifle with a suppressor, York County District Attorney Tim Barker said.

He said the suspect fired multiple rounds at the four officers at the door, killing three of them. A gunfight then ensued between Ruth and two officers outside. Ruth wounded a sheriff’s deputy before police shot the gunman to death, Barker said.
