After Casey Anthony was arrested on child neglect charges in the disappearance of her 2-year-old daughter Caylee, she seemed more concerned about getting in touch with her boyfriend,Tony Lazzaro, than she was about the whereabouts of her little girl, according to Investigation Discovery’s Casey Anthony: An American Murder Mystery. But many people don’t remember that her then-boyfriend had a big role in her trial — he took the stand and testified in the murder trial of little Caylee.

Tony and Casey met on Facebook.

They first met just weeks before the disappearance or death of Caylee, ABC News reported at the time.

Tony spent a lot of time with Caylee and Casey.

He said that during one of the first times he met Caylee, she came over with a book and a teddy bear, according to his testimony footage. They went down to the pool at his apartment complex. He said that Casey was a good mother and she disciplined Caylee when she got too close to the edge of the pool like “any mother would do.”

Caylee also liked to watch the children’s cartoon Dora the Explorer and she could count to 40 in Spanish, which he said was “incredible for her age.”

Tony was in college during the time he dated Casey.

Originally from Long Island, Tony attended Full Sail University in Orlando for music and graduated in 2009, according to local paper Riverhead News Review. Casey lived with him at his apartment that he shared with roommates during the 31 days that her daughter was missing.

He said Casey never showed signs that her daughter was missed or dead.

Tony revealed that in the days after her daughter’s disappearance, Casey never appeared upset or sad and she never mentioned anything about it to him.

He kept in close contact with her in the days after Caylee was reported missing.

In a text message obtained by Reuters during the trial, Casey told Tony, “I’m the worst f–king person in the world.”

She also texted him the day after she reported her daughter missing and wrote, “If they don’t find her, guess who gets blamed and spends eternity in jail.”

In 2011, Casey was ultimately acquitted of murder and charges of aggravated child abuse and aggravated manslaughter of a child. However, she was found guilty on four counts of providing false information to a law enforcement officer. She was sentenced to one year in county jail and $1,000 in fines for each count.
