DARBY, Pa., July 25 (UPI) -- The gunman who shot a caseworker at a suburban Philadelphia hospital had a history of drug arrests and suicide attempts, police said.
Richard Plotts, 49, allegedly killed Theresa Hunt, 53, with a shot to the face during a meeting Thursday with her and Dr. Lee Silverman in an outpatient unit at Mercy-Fitzgerald Hospital in Darby. Silverman, who was grazed by a bullet, then used his own gun to critically wound Plotts, Delaware County District Attorney Jack Whelan said.
