Connecticut police have ruled that Dylan McDermott's mother was murdered by her now-dead gangster boyfriend in 1967, according to local paper The Republican-American.
Waterbury police said they've found evidence that would be enough to file murder charges against John Sponza, whose body was discovered in a trunk shot to death in 1972, in the death of Diane McDermott. They also found evidence to implicate him in at least two other unsolved homicides.
"Sponza is telling the police that night that he very rarely, if ever, had arguments, yet everyone we spoke to, including Dylan, who was only 5 at the time, remembered very violent, vicious arguments," Gugliotti said. "Dylan vividly recalls the amount of times, not only flashing the gun, but pointing it at the kid, saying, 'Shut up and get out of here.' He's still probably traumatized by that."
The Practice and American Horror Story star declined to comment to the paper, but his sister, Robin Herrera, said she is relieved by the findings. "I'm happy to know my mother wasn't mentally ill or depressed," she said. "Somebody took her from us; she didn't leave us."
