After arrest, Casey Anthony insisted her focus is on finding Caylee

(CNN) - In jail visits with her brother and parents following her arrest, Casey Anthony alternately cries, giggles, expresses love to her relatives and insists her sole focus is finding her 2-year-old daughter, Caylee, according to tapes of those visits played for jurors in her capital murder trial on Thursday.

"If you can speak to the media directly, my concern for me is Caylee," a tearful Anthony tells her brother, Lee Anthony, on July 25, 2008, from an Orange County, Florida, jail. "No one has said for me that I love my daughter, that I want her safety and that she and the rest of my family is my only concern. All I want is to see her again, to hear her laugh, to see her smile and to just be with our family. Nothing else matters to me at this point."

The same day, Anthony's mother, Cindy Anthony, asks her during a visit, "Are you protecting Caylee? Are you protecting me?"

"I'm protecting our family, yes," Anthony replies. "Not from anything I've done."

"Is someone threatening us?" Cindy Anthony asks, then asks again after receiving no answer.

"Just leave it at that, please," her crying daughter replies, adding that she will write her and elaborate. The family was careful about what they discussed, mindful the conversations were being recorded.

Now 25, Casey Anthony is charged with seven counts in Caylee's death, including first-degree murder, aggravated child abuse and misleading police. If convicted, she could face the death penalty.

She has pleaded not guilty and denied harming her daughter or having anything to do with the little girl's disappearance or death. Defense attorney Jose Baez has said that once all the facts are known, it will become clear his client is innocent.
