Alicia Witt, who first gained fame as a child actor in Dune and Twin Peaks, has spoken out after her parents’ shocking deaths last month.

Diane Witt, 75, and Robert Witt, 87, were found dead at their home in Worcester, Massachusetts after Alicia asked a relative to check on them. According to the Police and Fire Departments of Worcester, there was no sign of foul play or carbon monoxide in their home.

“It’s been a month since I got scared, not having heard back from them, and called to have them checked on. Waiting, phone in hand, praying fervently that the next call would be from them, angry I’d gotten someone else involved. Knowing as soon as I heard the detective’s voice on the other line that they were gone,” Witt began her tribute posted on Instagram and Facebook Tuesday.

Along with commending her parents as “brilliant educators, deeply kind, curious, intuitive,” the Walking Dead actor provided more details on the mysterious cause of their deaths. She claimed that her parents were “fiercely stubborn,” and were so solitary that they refused to allow workers inside their old house to make repairs. Witt even stated that the isolation went so far that she herself hadn’t visited her parents’ home in “well over a decade.”

Witt then revealed the horrific news that her mother and father likely died because their heater broke in the middle of winter, and they didn’t reach out to anyone for help. “I had no idea that their heat had gone out. I will never understand how or why they made the choice not to tell me this, not to let me help them with this. My heart is broken,” she wrote.

She finished the difficult and emotional statement with one simple declaration, “They love me so. I loved them so.”
