A gunman, armed with a handgun and carrying zip ties, went inside UPMC's ICU, and took staffers hostage before he was ultimately killed by police in a shootout, the York County DA said.

Authorities described the shooting of a gunman who opened fire at a Pennsylvania hospital as “absolutely justified, beyond any and all doubt.”

Officer Duarte had just celebrated his 30th birthday on Feb. 17, less than a week before Saturday’s shooting, according to the York County Coroner’s Office. He had been a West York police officer since June 2022 after serving five years with the Denver Police Department in Colorado.
