A troubled patient opened fire on a caseworker and psychiatrist in a small office at a unit of Mercy Fitzgerald Hospital in Delaware County on Thursday afternoon, police said, leading the doctor to draw his own weapon and shoot the assailant. The confrontation left the caseworker, 53-year-old Theresa Hunt, dead and the 52-year-old psychiatrist, a veteran doctor at the hospital whom sources identified as Lee Silverman, with a graze wound to the head. The patient, Richard Plotts, was in critical condition Thursday night from three gunshot wounds. Police vehicles swarmed the scene and armed officers charged through the building - the Sister Marie Lenahan Wellness Center, across Lansdowne Avenue from the main hospital - to evacuate doctors, nurses, and patients waiting for routine appointments. Authorities said they believed Silverman shot Plotts three times in the torso and arm. Late Thursday night, Mercy Fitzgerald released this statement regarding the deadly shooting:

"We are grateful for the efforts of the emergency responders, and we are working with the Delaware County police departments to understand fully the details of the event and to do all we can to assist those affected," hospital officials said in a statement. “I was hoping everyone was going to get out safe." Plotts has had run-ins with the doctor's and hospital staff in the past, Whelan said. Concerned, a hospital employee "actually opened the door, saw him pointing a gun at the doctor," Whelan said. They shut the door very quietly and one immediately called 911," Whelan said.  A psychiatric patient opened fire inside a wellness center in Darby, PA, Thursday, according to police.
