Gunman pleads guilty but mentally ill in hospital shootings

MEDIA, Pa. (AP) — A gunman has pleaded guilty but mentally ill to charges he killed his caseworker and wounded his psychiatrist at a suburban Philadelphia hospital complex last July.

Fifty-year-old Richard Plotts entered the pleas Tuesday to first-degree murder, attempted murder and illegally possessing a firearm.

The Upper Darby man killed 53-year-old Theresa Hunt at the Mercy Fitzgerald Hospital campus in Yeadon on July 24. He also grazed Dr. Lee Silverman in the temple and thumb before the doctor returned fire with his own gun and wounded Plotts to end the siege.

Public defender Charles Williams says Plotts faces life in prison when he's sentenced Sept. 25, but that the plea was in his best interest. He says Plotts never wanted to put his or the victims' families through a trial.
