Hostage Situation and Shooting at UPMC Memorial Hospital, York, Pennsylvania

On February 22, 2025, a mass shooting and hostage situation took place at UPMC Memorial Hospital in Shiloh, Pennsylvania, United States, near the city of York. The shooting began at around 10:35 a.m. when Diogenes Archangel-Ortiz took hostages at the intensive care unit (ICU) area of the hospital and opened fire on several people. Two people, including the shooter, were killed and five others were shot.

UPMC Memorial Hospital is a 104-bed hospital operated by University of Pittsburgh Medical Center that opened in August 2019. It provides emergency medical, cardiology, vascular, chronic disease management, and surgical services.

Archangel entered the hospital at 10:30 a.m. carrying a backpack containing a semi-automatic pistol, zip ties and duct tape. He entered the ICU area of the hospital near the main entrance and opened fire after taking hostages at 10:35 a.m. Archangel then barricaded himself inside the hospital. Later, when he came into the hallway with a female ICU employee at gunpoint with zip ties restraining her hands, both police officers and Archangel engaged in a shootout, in which he was fatally wounded. An officer was killed during the gunfire exchange. The attack was confirmed to be targeted.

West York officer Andrew Duarte was killed in the shooting. His death was confirmed in a Facebook post by the West York Borough. Duarte was a law enforcement veteran and joined the police department in 2022 after working for five years with the Denver Police Department in Colorado as a patrol officer. Duarte was highly regarded according to the Denver Police Department and received a hero award in 2021.

At least five people, including two police officers, a doctor, a nurse, and a custodian were wounded by gunshot but reported to be in stable condition. Another staff member was injured in a fall.

The perpetrator was identified as 49-year-old Diogenes Archangel-Ortiz, who had lived in York since the 1990s and was born in the Bronx, New York to Dominican parents. He previously had contact with the ICU and went to the hospital at least once before the attack and the week prior to the shooting he had contacted ICU for a medical purpose that had involved his wife. Archangel-Ortiz had been removed from the hospital by security the night before the shooting after his wife died in hospice earlier that night. Anger and grief were identified as motives for the shooting. Archangel-Ortiz also had an extensive criminal history across the York area between 2007 and 2025 prior to the shooting.
