Authorities are seeking a suspect in the fatal shooting of a rookie police officer.
Pennsylvania state police have issued an arrest warrant for 29-year-old Rahmael Sal Holt. He's accused of killing New Kensington Officer Brian Shaw during a traffic stop Friday night.
Authorities say the 25-year-old Shaw was shot in the chest while chasing Holt on foot. He was taken to a hospital, where he was pronounced dead.
Holt faces charges of murder and murder of a police officer.
Police arrested 27-year-old Tavon Jamere Harper, of New Kensington, who they say was driving the Jeep that Holt was believed to be a passenger in. He's charged with fleeing the scene.
Investigators say they know why the traffic stop occurred. But they won't provide further details, citing the ongoing investigation.
Shaw had served as a part-time officer in three other towns before joining the New Kensington force full time in June.
New Kensington is about 18 miles northeast of Pittsburgh.
