"You know what happened to Caylee – and you know where Caylee is," Yuri Melich said

June 02, 2011 12:10 PM

A miserable-looking Casey Anthony shook her head and sighed deeply in court on Thursday as prosecutors played more from a recording of her July 2008 interview with police officers.

The seven women and five men on the jury listened intently as detective Yuri Melich testified that Anthony, 25, claimed she worked at Universal Studios when Caylee went missing in 2008. When officers took her to her supposed workplace, she led them on a meandering tour of the offices before finally admitting that she was lying. “She was very convincing,” Melich testified.

Things got more intense when the prosecutor played the recording, in which Anthony maintained that a babysitter named Zenaida Gonzalez had kidnapped Caylee. “This is the honest to God’s truth,” Anthony said in the recording. “I don’t know where she is. The last person that I saw her with is Zenaida.”

Melich was not convinced. “Listen, we know that’s not true,” he said. “We already know that you’re not telling us the truth. You know what happened to Caylee – and you know where Caylee is.”

Throughout the 40-minute recording, Melich alternated between being aggressive and casual as he tried to get Anthony to reveal Caylee’s whereabouts. “I can look at you as a person who’s scared,” he said, “or we can look at you as cold, callous and a monster who doesn’t care. It’s gonna be one of those two options.”

Despite Melich’s efforts, Anthony maintained that Caylee had been kidnapped by the fictitious Zenaida Gonzalez, a claim that her attorneys now admit was a lie.

Anthony is on trial for the murder of her two-year-old daughter, Caylee. She faces the death penalty if she is convicted.
