Police responded to an active shooter incident at a hospital in York, Pennsylvania, on Saturday morning and there is no ongoing threat, officials said.

A police officer was killed Saturday after responding to a shooting at UPMC Memorial Hospital just outside of Harrisburg, Pennsylvania, where the suspected gunman also was killed, according to state police.

Anguish and anger at the very recent loss of a loved one apparently spurred on the man who would target the intensive care unit at a Pennsylvania hospital Saturday morning, a senior law enforcement official briefed on the investigation told ABC News.
