The biological mother of the man who was allegedly held captive for 20 years by his stepmother in her Waterbury, Connecticut, home lashed out at the accused woman in an interview with Fox News Digital. 

Tracy Vallerand, who lost custody of her son when he was 6 months old, slammed his stepmom, Kimberly Sullivan, calling her the “lowest of the low.”

Vallerand, who noted that she prefers to call Sullivan “it” rather than referring to her as a human being, said Sullivan is a flight risk and shouldn’t have been allowed out on bail at all.

Kaloidis previously denied the allegations against his client in an interview with Fox News Digital. 

“This has been an extreme shock to her,” he said of Sullivan. “She lived a relatively quiet life. Her side of the story is quite simple. She did not harm him. She did not restrain him. She did not imprison him.”

Kaloidis declined to comment through a spokesperson.

Last week, Sullivan’s stepson broke his silence, going only by the name “S.”

“I am much better and stronger than I was the day the first responders carried me out of my home. I am beyond grateful for the care I have received since then,” he said in a statement. “To all the health care professionals who have helped and nurtured me, thank you. In addition to all of your care, I appreciated the chance to have my first ever birthday party to celebrate turning 32.”

“I also want to thank the first responders, the law enforcement investigators and everyone who is working to hold those responsible for my abuse accountable,” he said.

“Much has already been said that tells part of the story of the abuse I endured. Someday, perhaps my whole story will be told.

“I ask everyone involved in my story to fully cooperate with the authorities who are helping me seek justice for these crimes. I also ask the public and the media to respect those investigations and my privacy as this process plays out. This isn’t just a story. It’s my life.”
