MEDIA COURTHOUSE >> Richard S. Plotts entered an open plea of guilty but mentally ill on Tuesday to charges of murder in the first degree, attempted murder and illegally possessing a firearm in the July 24, 2014, shooting at Mercy Fitzgerald Hospital.
Killed during the shooting inside the Sister Marie Lenahan Wellness Center on Mercy Fitzgerald Hospital’s Yeadon campus was Plotts’ mental health caseworker, Theresa Hunt.
Plotts, 50, of Upper Darby, also admitted to shooting at psychiatrist Dr. Lee Silverman after killing Hunt. Silverman returned fire with a firearm he keeps in his desk drawer, critically wounding Plotts and allowing for his capture.
As a convicted felon for a prior robbery conviction with a history of weapons charges going back to 1990, Plotts was not allowed to own or possess a firearm.
Assistant District Attorney Michael Mattson offered a post-mortem report Tuesday indicating Hunt had died from two gunshot wounds to the head, as well as transcripts of statements given by Silverman to law enforcement and an affidavit of probable cause as the basis for the plea.
Plotts is currently housed at the State Correctional Institution in Graterford, where he said he has weekly access to a psychiatrist. He was well groomed with beard stubble and dressed in a blue, button-down Department of Corrections shirt at Tuesday’s hearing.
Mattson and defense attorney Chuck Williams also stipulated to a psychiatric evaluation by psychiatrist Dr. Stephen Mechanick.
District Attorney Jack Whelan said following his arrest that Plotts had more than 30 additional rounds of ammunition in his pockets and investigators believe he was prepared to kill more people.
Plotts appeared lucid and aware Tuesday as he answered questions from his attorney and indicated he wanted to enter the plea.
