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