Bodycam footage from the Waterbury Police Department shows suspected Connecticut child abuser Kimberly Sullivan denying that her stepson, who was allegedly locked in a storage closet in their home for 20 years, was imprisoned in the house. 

According to the footage obtained by Fox News Digital, one of Sullivan’s two daughters arrived at the scene shortly after authorities on Feb. 17, when police said her 32-year-old stepson set fire in the house to escape decades of captivity and abuse.

Sullivan’s daughter picked her up in a black Acura, where they waited nearby as firefighters extinguished the blaze, and as Sullivan’s unnamed stepson was rescued from the home. 

In the footage, which is partially redacted, Sullivan, 56, explains to an officer what happened after the fire started.

She said that she thought the fire started from a TV her stepson plugged into the wall, and said that she came out of her bedroom when she smelled smoke and called out for him.   

“I was trying to go into the room but it was just – there were just flames – he came out of the room, eventually woke up and came out of the room,” she said. 

Sullivan said that her son couldn’t escape the room because there were flames, but that he must have walked through them eventually.  

“Was the door locked on his room, or no?” the officer asked. 

“No,” Sullivan replied. 

“OK, is it normally locked?” he asked.

“No,” she answered. 

“And he has free rein to go out of there whenever he wants?” the detective asked. 

“Yeah,” Sullivan said. 

But police allege that Sullivan was lying during that exchange.

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 is free on $300,000 bond, and pleaded not guilty to all charges on Friday. 

According to an arrest warrant for Sullivan, the victim, identified as “Male Victim 1,” was held in a windowless 8-foot by 9-foot storage closet with no air conditioning or heat and without access to a bathroom for 20 years. He was kept inside the closet 22-24 hours per day.

He was allowed two sandwiches and two small water bottles each day, one of which he would use for bathing. He disposed of his waste using water bottles and newspaper. The man weighed less than 70 pounds when first responders found him after the fire.

That warrant also says that Sullivan’s stepson told them he set the fire on purpose, because he wanted his freedom.

In a heavily redacted portion of the bodycam footage, police officers can be seen standing outside the ambulance looking in at the victim, who is blurred and being tended to by a paramedic. When audio reemerges from the redaction, one officer tells another that the victim said he hadn’t showered in a year.
