“It cuts us to the core that such an event could happen,” Noonan said.

Investigators were interviewing a “person of interest” Saturday morning, but no arrests had been made, state police spokeswoman Trooper Connie Devens said.

Earlier, Noonan said police had no description of the shooters or any information about the motive. But Noonan said “this attack seems to be directed particularly at the Pennsylvania State Police.”

The shooting happened at 10:50 p.m. Friday night.

Police from New York, New Jersey and throughout the Northeast are assisting in the search for the shooter or shooters, Noonan said.
