Real Life Horror For 'American Horror Story' Actor Dylan McDermott, Mother Confirmed Murdered 45 Years Ago

Dylan McDermott, the star of season one of "American Horror Story" has faced some horrible situations on screen, but it turns out the actor has also faced some real life horror.

Hollywood.com reports that on February 9, 1967, McDermott lost his mother at the age of five. Diane McDermott had been fatally shot. At the time her death was ruled an accident, with police believing that the mother had shot herself with a gun her boyfriend at the time had been polishing. Last year Diane's case was reopened after the actor met with Police Superintendent Michael Gugliotti and Mayor Neil M. O'Leary of Waterbury, Conn. Police have now concluded that Dylan McDermott's mother had been murdered by then-boyfriend John Sponza.

The closure finally came after investigators reviewed the autopsy, reports the New York Daily News. According to the autopsy, the weapon that murdered Diane had been pressed to the back of her head. The gun found near the body was also deemed too small to have been the weapon that killed her.

While police have enough to charge Sponza with not only the murder of Diane McDermott, but also involvement in two other cold cases, the man who was tied to organized crime cannot be charged. Sponza was shot to death in 1972. His body was found in the trunk of a car in a Massachusetts supermarket parking lot.

"It shapes you forever," McDermott had revealed to Esquire in 2010 of his mother's death. "And you don't get over it."

Police have quotes from the now 50-year-old actor from the time of his mothers death. Police Superintendent Gugliotti revealed that while Sponza denied fighting with his girlfriend, 5-year-old McDermott had told authorities about fights. "Not only flashing the gun, but pointing it at the kid, saying 'Shut up and get out of here,'" said Gugliotti.

Upon learning of the new ruling in her mothers death, Dylan McDermott's sister, Robin Herrera told Fox Nes that she was "happy to know my mother wasn't mentally ill or depressed. Somebody took her from us; she didn't leave us."

Dylan McDermott can be seen in the upcoming release of "The Perks of Being a Wallflower."
