Biological mom of Connecticut house of horrors victim says alleged wicked stepmother should ‘rot in hell,’ claims she looked for him ‘for so long’

The biological mother of a horrifically abused 32-year-old man who was rescued from a Connecticut home has a blunt message for his stepmom, Kimberly Sullivan, who allegedly imprisoned her son for more than two decades.

“She can rot in hell,” the 52-year-old, who gave up custody of the unidentified victim when he was a child, told NBC Connecticut on Tuesday.

“She needs to spend the rest of her life in solitary confinement and fed two cups of water a day,” she added, referring to the cruelly meager portions of food and water the victim allegedly subsisted on during his 20-year captivity.

Although she didn’t have an answer when The Post asked her last weekend why she didn’t try to rescue her son, the alleged victim’s mother and one of his half-sisters told the outlet they “looked for him for so long,” and started searching the internet for any trace of him once he turned 18.

“I’ve been looking for him for over a decade … there was nothing. No social media, no court records, no ancestry information, nothing,” his 35-year-old half-sister said.

“We love him, I love him. He is so strong and I’m so proud of him for doing what he needed to do. I wish he did it sooner,” the mom said when asked what she’d say to her son if he were in the room.

The man told police he deliberately set fire to the run-down Waterbury home in a desperate bid for freedom, knowing it would draw emergency responders.

He had been pulled out of school by his stepmother at the age of 11 after two visits from child services, who received reports that the boy was seen eating out of garbage cans. He was never re-enrolled, and never continued formal education from then on, he told detectives.

Sullivan’s arrest warrant shows her stepson told investigators the reason he never tried to escape or attract attention by breaking a window was because she told him nobody was to ever lay eyes on him “under pain of death.”

The stepson’s nightmarish imprisonment continued getting worse over the years, ramping up severely when his biological father died in January 2024, at which point he was locked in his room between 22-24 hours per day, he told police.

Sullivan’s attorney said his client maintains her innocence, and told The Post there is “more to the story” which will soon come to light.

Her next court appearance is March 26.
