Authorities described the shooting of a gunman who opened fire at a Pennsylvania hospital as “absolutely justified, beyond any and all doubt.”

A West York Borough police officer and a gunman were killed in a shooting Saturday morning that injured multiple staffers at UPMC Memorial Hospital in York County, Pennsylvania, the district attorney said.

Workers at a Pennsylvania hospital who were injured during a shooting that left the gunman and a police officer dead are reported in “medically stable” condition.
