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.

A 49-year-old gunman was shot and killed by police after they said he held multiple UPMC staff members hostage and shot multiple people.

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.
