A procession with law enforcement officers is planned for the funeral of a Pennsylvania police officer who was shot and killed while responding to an attack on a hospital intensive care unit.

A police officer who was shot to death while responding to an armed man with hostages inside a Pennsylvania hospital intensive care unit was remembered Friday as a dedicated public servant who did not hesitate to run toward danger and died a hero.

Investigators are trying to determine why a man targeted a Pennsylvania hospital, taking workers inside the intensive care unit hostage and holding one staff member at gunpoint as her hands were bound by zip ties.
