Kimberly Sullivan, who is charged with locking her stepson in a room in their Connecticut home for 20 years, denies abusing the man who was severely emaciated when he was finally rescued after setting their house on fire, according to her attorney.

“Her side of the story is quite simple,” Ioannis Kaloidis told Fox News. “She did not harm him, she did not restrain him, she did not imprison him.”

“This has been an extreme shock to her,” Kaloidis added. “She lived a relatively quiet life.”

“Her face has been plastered all over the TV, the news, the internet, social media. Her life has been turned upside down. She has a giant target on her back. She has essentially become public enemy number one. It is a tremendous weight that she is carrying. It is a tremendous upheaval to her entire life,” the attorney griped. 

Sullivan’s 32-year-old stepson was pulled out of her burning Waterbury home by firefighters on Feb. 17 — when he weighed just 68 pounds — and revealed to police that he deliberately started the blaze in a desperate bid to escape the tiny windowless space where he’d been confined since he was 11 years old.

The shocking story made national headlines as police released disturbing footage and images from inside the disheveled home that showed the deplorable conditions Sullivan’s stepson was forced to endure.

According to her arrest warrant, she kept her stepson in the 8-foot by 9-foot room with no air conditioning or heat and without access to a bathroom for 22-24 hours a day for 20 years.

The man told investigators he was allotted two sandwiches and two small water bottles each day. He would use one of the water bottles to bathe himself.

He was forced to relieve himself using bottles and newspapers, he told police.

Sullivan was arrested on March 12 and charged with first-degree assault, second-degree kidnapping, first-degree unlawful restraint, cruelty to persons and first-degree reckless endangerment.

She was released from jail less than a day later on a $300,000 bond. 

Sullivan has maintained her innocence, claiming that her stepson was free to come and go as he pleased and is blaming the man’s late father, Kregg Sullivan, for the unspeakable abuse.

“My client adamantly denies that there was any imprisonment,” Kaloidis said. As for the whole history, there’s a lot that I anticipate will come out over the course of the trial, hopefully, because I think that’s the appropriate place for the release of any additional information.”
