This week marked the tenth anniversary of Casey Anthony controversially being acquitted of the murder of her two year-old daughter Caylee.

Now, Anthony’s former cellblock neighbor and friend Robyn Adams is speaking out to describe her experiences with the woman who many Americans feel got away with murdering her own child.

In Lifetime’s new series “Cellmate Secrets,” Adams recalls meeting Anthony while in an Orange County, Florida jail in 2008. While they weren’t allowed to speak to each other, Adams said they used “hand signals” to talk from their cell windows. They also reportedly wrote letters to each other and hid them in books, according to Yahoo News.

“We would ask each other, ‘Did you write me?'” Robyn explained as she mimicked the hand signs they made. “‘Yes, it’s in the book.'”

One moment Adams has never forgotten is when Anthony learned that the Orange County Sheriff’s Office had found the body of her two year-old daughter Caylee.

“When they gave her the news that they found Caylee’s remains, it was bad,” Adams recalled. “They took her to medical, because she couldn’t breathe. She was having an anxiety attack, a panic attack.”

Prison guard Silvia Hernandez, however, had an entirely different perspective on the situation.

“She didn’t act like a regular mother, where ‘oh they found my daughter and she’s dead?’—you know, crying, bawling,” Hernandez said. “No, no her behavior at that time was like, ‘oh, s–t. I got caught.'”

This comes days after a male juror who preferred not to be named publicly said that he still has regrets about Anthony’s verdict.

“My decision haunts me to this day,” he said. “I think now if I were to do it over again, I’d push harder to convict her of one of the lesser charges like aggravated manslaughter. At least that. Or child abuse. I didn’t know what the hell I was doing, and I didn’t stand up for what I believed in at the time.”

Anthony was acquitted of all serious charges in this case, only being found guilty of lying to law enforcement and sentenced to four years in prison. However, she ultimately only stayed in prison for twelve days after factoring in time already served.

Anthony’s daughter Caylee would be turning 17 this coming August.
