A police officer who was fatally shot during a standoff at UPMC Memorial Hospital in York, Pennsylvania, in February was struck by friendly fire, the York County District Attorney’s Office confirmed this week.

West York Borough Police Officer Andrew “Andy” Duarte, 30, was among the first responders to a chaotic and violent scene that unfolded on the morning of February 22, 2025, when a gunman entered the hospital’s intensive care unit (ICU), taking multiple hostages and injuring several individuals before being fatally shot by police.

According to District Attorney Tim Barker, officers justifiably used deadly force against the suspect, 49-year-old Diogenes Archangel-Ortiz, who had already shot several hospital staff members. However, during the final confrontation, Duarte was inadvertently killed by a fellow officer.

The Hospital Siege

The ordeal began shortly before 5 a.m. when Archangel-Ortiz, armed with a 9mm pistol stolen from a family member, entered the hospital’s ICU. He brought with him zip ties, indicating a premeditated plan to restrain and control hostages.

Archangel-Ortiz had reportedly been at the ICU earlier in the week, accompanying a patient during a medical visit, suggesting the unit was specifically targeted. Authorities are still investigating the motive.

During the standoff, the gunman shot and injured three hospital employees a physician, a nurse, and a custodian. A fourth staff member was hurt while attempting to escape the scene. Additionally, two police officers were injured during the confrontation.

The standoff ended when Archangel-Ortiz attempted to exit the ICU with a hostage. Officers opened fire, killing him on the spot. Investigators later discovered that the gunman’s pistol was unloaded at the time of the shooting.

In the exchange, Officer Duarte was struck by bullets fired by a fellow officer. Despite being critically wounded, Duarte managed to assist a wounded colleague to safety before succumbing to his injuries.

A Hero Remembered

Officer Duarte joined the West York Borough Police Department in 2022 after serving with the Denver Police Department for five years. Known for his dedication, Duarte received a “Hero Award” in 2021 from Mothers Against Drunk Driving (MADD) for his work on DUI enforcement.

Police Chief Matthew Millsaps praised Duarte’s final act as one of “selfless courage.”

Governor Josh Shapiro also honored the fallen officer in a statement, calling Duarte “a true public servant whose bravery saved lives.”

Duarte’s funeral was held on February 29, drawing hundreds of mourners, including fellow officers, state officials, and members of the community.

Investigation and Policy Response

DA Tim Barker emphasized that although Duarte’s death was caused by friendly fire, no criminal charges would be filed. The officers involved acted appropriately based on the circumstances and information they had at the time.

The incident has, however, reignited discussions about tactical communication and de-escalation strategies during hostage crises.

The Pennsylvania State Police, in coordination with local agencies, has initiated a review of current active shooter protocols and is working with hospital administrators to strengthen emergency preparedness.

Mental Health and Security Concerns

Hospital staff who survived the attack are receiving counseling and trauma support services. UPMC, one of the state’s largest healthcare providers, stated it is conducting a security audit across all facilities.

The Pennsylvania Department of Health (health.pa.gov) encourages hospitals to update their emergency preparedness plans regularly and work closely with local law enforcement to prepare for possible violent incidents.

A Community in Mourning

The city of York and surrounding boroughs continue to grieve the loss of Officer Duarte. Candlelight vigils and fundraisers have been held in his memory, and a scholarship for aspiring police officers is being established in his name.

The National Law Enforcement Officers Memorial Fund has also confirmed that Duarte’s name will be engraved on the memorial wall in Washington, D.C., during the 2026 Police Week ceremonies.

While his loss is deeply felt by colleagues and the community he served, his final act of courage remains a powerful testament to his character and commitment.
