The shooter entered the hospital at around 10:30 a.m., carrying a backpack containing a semi-automatic handgun, zip ties, and duct tape. He made his way to the intensive care unit (ICU) area, where he took several hospital staff members hostage.
Archangel-Ortiz's actions resulted in a tragic loss of life and injuries to multiple individuals. Among those injured were a doctor, a nurse, and a custodian, who suffered gunshot wounds, and a fourth employee who was hurt while attempting to escape. The shooter's actions had a profound impact on the community, with Governor Josh Shapiro ordering flags to be flown at half-mast across Pennsylvania to honor the fallen officer, Andrew Duarte.
The motive behind Archangel-Ortiz's attack was attributed to his anger and grief over the loss of his wife, who had passed away in hospice care. He had a prior encounter with the hospital staff earlier in the week when visiting the ICU, which did not go well according to York County District Attorney Tim Barker. Additionally, Archangel-Ortiz had an extensive criminal history in the York area between 2007 and 2025.

This incident highlighted the issues within the healthcare system, including understaffing, overworked employees, and the high costs of medicines and supplies.
