The gunman who held intensive care unit staff hostage at UPMC Memorial Hospital in Pennsylvania before killing a police officer and injuring five other people Saturday believed that more could have been done to save his wife,

Cops encountered Archangel-Ortiz holding a female staffer at gunpoint with her hands bound, officials said. The officers engaged Archangel-Ortiz in a firefight, killing him. Archangel-Ortiz wounded two cops and killed a third, who was identified as Andrew Duarte, 30, of the West York Borough Police Department.

Authorities say a gunman entered a Pennsylvania hospital’s intensive care unit and took staff members hostage before he was killed by police.

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

A gunman, armed with a handgun and carrying zip ties, went inside UPMC's ICU, and took staffers hostage before he was ultimately killed by police in a shootout, the York County DA said.

The suspect, Diogenes Archangel Ortiz, entered the hospital with handgun and zip ties Saturday morning and took several staff members hostage, state officials said.
