Andrew William Duarte was a 30-year-old patrolman with the West York Borough Police Department who was killed on February 22, 2025, while responding to an active shooter at UPMC Memorial Hospital in York County. The attacker, identified as 49-year-old Diogenes Archangel-Ortiz, entered the hospital armed with a semiautomatic handgun and a bag said to contain additional weapons and zip ties, then took staff members hostage.

Officers engaged the shooter and fatally struck Archangel-Ortiz. Duarte was hit by pellets from another officer’s shotgun blast during the exchange and suffered fatal wounds to his arm and chest. The York County District Attorney stated Duarte’s death was a direct result of Archangel-Ortiz’s actions. Two officers and three hospital staff were also reported injured.

Duarte had previously served with other departments including the Denver Police Department, where he was recognized for DUI enforcement work. Tributes and regional law enforcement attendance at his funeral were noted; he had celebrated his 30th birthday days before he died.
