The "Walking Dead" actor wrote a moving tribute to her mother and father, who were found dead in their Massachusetts home last month.
Alicia Witt, best known for her roles in 1984's "Dune" and "The Walking Dead," has broken her silence about the sudden death of her parents.
Diane Witt, 75, and Robert Witt, 87, were found dead on December 20 by a relative at their home in Worcester, Massachusetts.
"It still doesn't feel real," Witt, 46, began an Instagram post Tuesday. "It's been a month since I was terrified, hadn't heard back from them, and called to check on them. Waiting, phone in hand, praying excitedly that the next call would be from them, angrily I'll add someone else."
But when the phone rang, the voice of another was that of a spy. Witt said he knew immediately that his mom and dad were gone.
Diane Witt, a former reading specialist, set a Guinness World Record in the 1980s for her hair, which, according to her obituary, measured 12 feet, 8 inches. Robert Witt was a retired science teacher.
In his post, Witt addressed the mysterious circumstances surrounding the death of his parents. Worcester Police Department's director of media relations, Kathleen Daly-Shea, told TODAY Parents earlier that there were "no signs of foul play."
Worcester Fire Deputy Chief Adam Roche said there were no signs of carbon monoxide at the residence.
"I was not allowed inside my parents' house for over a decade; every time I offered them some repairs, they refused to let the workers into their house. I begged cried, tried to reason with them, tried to convince them to let me help them move on - but each time, they got angry with me, telling me I had no right to tell them It's how he wants to live his life and he has it all under control," Witt wrote. "It wasn't for lack of effort on my part, or on the part of other people who loved them."
Witt described his parents as "superb teachers, deeply kind, curious, intuitive, intelligent, young at heart, funny," and "extremely stubborn."
“I struggle, as much as I helped, what more could I have done – short of petitioning the court system to exercise control over two other very fast, very independent, very capable adults. They are a cohesive, underlying, indivisible force. Were, determined to do things their own way," the actor wrote. "Knowing that they are into each other - the way they have to contend with, to do so really feels like It would have destroyed them."
Witt did not share the cause of his death, but said the heat had gone out in his home.
"I will never understand how or why they chose not to tell me, not let me help them with this. My heart is broken," she wrote. "And even if I could take a crystal ball and look into the future - if I could say to them 'You're going to break my heart and the hearts of everyone who puts you in the worst-case scenario' fall in love with you if you don't let us help you' - I still think they may have made the same choices. They weren't ready to make different choices.
"Our last words to each other were 'I love you.' That part was simple; never a doubt. They loved me so much. I loved them dearly."
