DARBY, Pa. (WPVI) --The brother of a woman gunned down inside Mercy Fitzgerald Hospital is sharing his pain with Action News.
"I am kind of angry at the gentleman who did it, and I think I'd really want to know why."
Dennis Hunt's little sister, 53-year-old Theresa Hunt, is gone. She was shot and killed, authorities say, at the hands of Richard Plotts.
He says his sister was one of the youngest of nine siblings, but she loomed large in the family. They called her "Mother Theresa".
Dennis says, "I want people to remember my sister as someone who was strong and stands up for what she believes in and good hearted... I don't know what to say."
Investigators say Plotts, who suffers from mental illness, was angry the hospital posted signs it was gun free.
He allegedly pulled his weapon, shot his caseworker, Hunt, in the head, and then turned the gun on his psychiatrist, Dr. Lee Silverman.
Silverman suffered a graze wound, but quickly pulled his own gun and shot Plotts multiple times.
District Attorney Jack Whalen say Plotts had more than three dozen rounds of ammunition on him.
"When you are coming into a facility and you have bullets in your pocket, and you have a revolver in your waistband, there's only one intent and that is to reload. That's why you have those bullets - your intent is to reload," Whelan said.
Whalen and others say Dr. Silverman likely prevented further carnage.
Dennis agrees, telling us, "I think that doctor who actually was armed, I think was incredible, what he did."
On Friday detectives searched Plotts' Clifton Heights apartment. Sources say other guns were found and it appears the 49 year old career criminal was a hoarder.
Dennis Hunt still doesn't understand why his sister was shot - especially after a nun from Mercy Fitzgerald told him this.
"She said that [Plotts] always said, 'She's done so much for me. I owe her so much.' And I just, I think that's what makes it all the harder," Hunt explained.
Dennis says there will be a memorial service for his sister in Havertown in the coming days. She will then be buried in northern Pennsylvania at a family plot.
