HARRISBURG, Pa. (AP) — A funeral service will be held later this week for a Pennsylvania police officer shot and killed while responding to a hospital intensive care unit where authorities said a gunman had shot three hospital employees and taken staff members hostage last weekend.

Authorities said the suspect held hospital workers hostage, opened fire and shot people including a doctor, a nurse, a custodian, and 3 officers.

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.

A gunman and a responding officer were killed after shots were fired Saturday at a hospital in central Pennsylvania.

A man who took hostages at UPMC hospital during a shooting that killed a police officer and wounded five others highlights the rising violence against U.S. healthcare workers.

The man who authorities say entered a Pennsylvania hospital with zip ties and a pistol over the weekend had recent contact with the hospital's intensive care unit, where he took staff members hostage and was killed in a shootout that left a police officer dead and others injured.
