According to a senior law enforcement official briefed on the investigation, the man was motivated by anger and anguish over the recent death of his family member. He targeted the intensive care unit at a Pennsylvania Hospital early Saturday morning.

According to officials, an officer was killed and at least five others were injured in the hostage situation that took place at a York County hospital.

At around 10:30 a.m. on Saturday, Diogenes Archangel-Ortiz, armed with a semi-automatic handgun and zip ties, entered UPMC Memorial in West Manchester Township. In a press conference held that day, officials said he entered the ICU, where he took several staff hostage.

Officials stated that Ortiz shot a doctor at the hospital, as well as an assistant nurse and a caretaker. Three police officers were also injured, and one died.

The Borough confirmed that Andrew Duarte was a police officer who died in West York Borough. Two other officers remain in stable condition in the hospital.

According to the official, Archangel Oriz could not accept that a member of his family had terminal cancer.

The family member had died within the last week.

According to the senior official, when Archangel Oriz arrived at the hospital on Saturday, he went directly to the ICU where a team of doctors were present, one of whom had treated a family member previously.

It is possible that Archangel Ortiz was the only person to be involved in this incident.

Tim Barker, York County District Attorney, stated: “This is a huge loss for our community. Officer Duarte gave his life to protect others. “

Multiple agencies, including the West York Borough Police Department and the Pennsylvania State Police, responded. Officers attempted to negotiate with Ortiz, but he appeared holding a hospital worker at gunpoint with her hands bound by zip ties.

“The officers were left with no recourse,” Barker said. “They opened fire, killing Ortiz and preventing further loss of life.”

“After reviewing surveillance footage and witness statements, it is clear and beyond any doubt that the officers acted lawfully in using deadly force,” he said. “Quite frankly, they needed to—because by doing so, they potentially saved even more lives.”

UPMC reported that no patients had been injured.
