A man who once lived with Casey Anthony says the woman accused of killing her daughter more than a decade ago is “lying about everything” when she publicly describes young Caylee’s disappearance.

According to the UK Daily Mail, Clint House elaborated on what he observed in Anthony’s public statements following her acquittal on charges related to the 2-year-old girl’s death.

She said at that time that she was able to “sleep pretty good at night,” he said, describing that as an unusual reaction to the situation.

The interview is set to air in its entirety Sunday on the Reelz network and includes additional speculation from the former roommate.

“If I was put on trial for killing my kid, and I was acquitted because I didn’t do it, as soon as I walked out those doors at the courthouse, I would be on a manhunt trying to find out who killed my kid,” House said. “I wouldn’t sleep again until I found out who killed my kid. That says everything you need to know.”

He also said he saw Anthony take part in a competition he hosted at a nightclub in the area, which he described as a “hot body contest,” in the immediate aftermath of Caylee’s disappearance.

“At that time, none of us knew that Caylee was missing,” House said.

It was “after the fact” that the girl’s disappearance became widespread knowledge that he said he and others in Anthony’s circle of friends became alarmed at her behavior.

“We were shocked and surprised that she could be out here doing what she had been doing that night, and meanwhile, her child is missing,” House said. “It came as a big shock once we found out about it. But we just didn’t know.”

He said he had the opportunity to interact with Caylee during her short life, describing her as “probably one of the sweetest little girls” and “very articulate for her age.”

Before the girl’s disappearance, House said the mother and daughter seemed like a perfectly normal family. He described Anthony as giving every appearance of being a “very loving, attentive mother.”

House reiterated portions of his testimony from trial, claiming in the new interview that he “never saw her have to discipline Caylee because Caylee was such a well-behaved child.”
