ORLANDO, Fla. -- The grandparents of a missing 2-year-old Orlando girl met with investigators for more than six hours, relaying what their daughter has told them, Local 6 News reported.

Cindy Anthony would not disclose what the family discussed with investigators on Wednesday, but said she is convinced her granddaughter, Caylee Anthony, is alive and that her daughter, Casey Anthony, is innocent.

"My daughter may have some mistruths out there or half-truths, but she is not a murderer. You all are sucking the life right out of me every day, having to remind everybody that this is what it's all about," Cindy Anthony said while holding a flier of Caylee.

Casey Anthony told investigators that she left Caylee with a baby sitter named Zenaida at The Sawgrass Apartments in June, and the girl hasn't been seen since. Orange County sheriff's deputies said the apartment Casey Anthony led them to, Unit 210, was vacant and no one named Zenaida ever lived at the complex.

"She's leading you to a place, but she's not telling you the exact location to which apartment it is because she's afraid if someone walks in that something may happen to Caylee," Cindy Anthony said.

Casey Anthony is being held on child-neglect charges.

The family said on Thursday that it is still working on Casey Anthony's $500,000 bond.

'Who To Trust?'

Meanwhile, Casey Anthony was asked by her brother, Lee, during a jailhouse phone call who he can trust in the search for Caylee.

The call lasted more than three minutes, and was made public on Wednesday night.

"How is everything going?" Casey Anthony said to begin the call.

"It's going OK," Lee Anthony said. "How's everything going with you?"

"Good," Casey Anthony said. "Just took a shower and I figured I'd call and check in, say hi, since I got a chance to see mom and dad this morning."

"OK," Lee Anthony said.

Lee then tried to get information from his sister.

"I know there's some, you know, some people that referred to in the past, and you know, I'm just curious if, um, you know, anything has changed as far as who I can trust and all those type of things," Lee Anthony said.

"I mean as far as I'm concerned, nothing's really changed on that level," Casey Anthony said. "So, if anything does, I'll obviously let you know."

The call was dropped during the conversation.

But before it was dropped, Lee Anthony had one final thought.

"If there's ever anything particularly that I should look into or attempt to follow up on…"

"Yeah, I'll definitely let you know if things come up," Casey Anthony said. "If anything does (come up) at all."

Anthony's co-counsel Mike Walsh told Local 6 that it's hard on her not to be able to give her family what could be critical information about the whereabouts of her daughter.

"It's extremely frustrating," Walsh said. "The only people she can speak openly with are her defense lawyers. As long at it's a criminal investigation of Casey, then Casey has to watch what she says."

Request To Reduce Bond Denied

Casey Anthony and her attorneys were dealt a blow on Wednesday when an appeals court refused to consider lowering her bond.

"It's just we lost and that's it, denied," Walsh said. "One word -- denied."

However, Local 6 has learned that the fight to spring Anthony out of jail is not over. Her legal team will appeal to the state Supreme Court.

Anthony's legal team also said they've considered making a federal case out of it, Local 6's Adam Longo reported.

Mag Gives Insight Into Mother

A national magazine is giving more insight into who Casey Anthony is and what her relationship is like with her mother.

Friends of the 22-year-old shared their stories with People magazine for a cover story.

In the article, friends said, "She would complain about her mother and how she was trying to run her life. But then a few days later, she'd say how much she loved her mother and father."

A friend who has known Anthony since middle school describes her as "immature and strange at times."

The friend also said she is always surrounded by drama, according to the article.

Club Photos Surface

Photos showing Casey Anthony smiling with friends at an Orlando lounge apparently five days after the child was last seen by her grandmother have raised new questions about when Caylee disappeared.

A photographer snapped the photos showing Casey Anthony at the Fusian Lounge in Orlando on June 20 -- which is five days after missing Caylee Anthony was last seen by her grandmother.

"She was not partying any harder or less than anybody else would but she was at the medium," John Azzilona said. "She didn't seem belligerently drunk or anything like that, she was just out."

Also, about four days after the photos were taken, one of Anthony's friends said he heard Caylee in the background of a phone call.

A national search continues for the missing girl.
