Leonard Padilla and his nephew, Tony Padilla, said they will arrive in Orlando on Sunday and post a $500,000 bond for Casey Anthony, the mother of Caylee, who has been missing since mid-June.

Leonard Padilla, who hosts a TV show called "Bounty Hunters" on National Geographic, told Local 6 News that he has been talking to Casey Anthony's attorney, Jose Baez, about bailing his client out of jail.

Leonard Padilla told Local 6 News that his nephew, Tony Padilla, a bail agent, is traveling to Texas and has made arrangements with a company to secure the entire $500,000 bond.

Leonard Padilla said he is bailing Casey Anthony out to find out the truth about Caylee.

"We eat in the same room, sleep in the same room. After a while, these people feel better than sitting in a cell looking at the walls, and they will discuss things that they won't discuss with parents or anybody else," Leonard Padilla said.

Leonard Padilla said he and Casey could stay at her parents' house, but he said he hasn't talked to George or Cindy Anthony. Leonard Padilla also said a home at an undisclosed location in Oralndo could be an option.

Earlier, threats against the family if Casey Anthony leaves jail prompted her mother, Cindy Anthony, to consider the use of a safe house.

"Right here, I don't think is the ideal place for her not because we don't want her in the house and everything, but we may have to hole her up somewhere in a safe house," Cindy Anthony said.

The Padillas announced the move in an e-mail to Local 6 News.

The e-mail stated:

"On Sunday, August 17, World Famous Bounty Hunter Leonard Padilla and his nephew Tony Padilla, owner of Tony Padilla Bail Bonds of Sacramento, CA., will be traveling to Orlando with two of Leonard Padilla's associates. Tony Padilla will be posting a $500,000.00 bond for the release of Casey Anthony."

Casey Anthony is being held on charges of child neglect and filing a false statement.

She reported Caylee missing in mid-July, 31 days after she said she last saw her daughter.

Family Appoints Spokesman

Also on Friday, the family of Caylee Anthony appointed a spokesman known for his work on other high-profile cases.

Larry Garrison will now be answering questions from the media, Cindy Anthony said.

Garrison, president of production company SilverCreek Entertainment, co-authored a book on the disappearance of missing Alabama teenager Natalee Holloway.

Garrison was also a spokesman for the family of John Mark Karr, the man who gained notoriety for falsely confessing to the murder of JonBenet Ramsey.

Sheriff: Kidnapping Theory Not Credible

Meanwhile, the Orange County sheriff said there is no credible evidence to support a contention by the family of Caylee that the child was kidnapped.

"Right now, I don't think there is any credible information on the kidnapping theory," Sheriff Kevin Beary said. "If it is accidental, then I need to know that and people with credible information need to come back and tell me that."

Beary said Casey Anthony needs to talk with deputies.

"I'm not going to beat up on anybody because it's a very tragic situation (but) we need her cooperation," Beary said. "She was probably the last person to see Caylee."

Beary said about 1,700 tips have been called in concerning the case.

He said his team has found no one with credible information.

Family Lashes Out

Caylee Anthony's grandparents lashed out at news reporters on Thursday over a question yelled at them as they walked to see the child's jailed mother.

"Do you have anything to say about a new theory that Caylee (Anthony) may be dead and that it may be an accident?" a reporter asked.

"Shut up," George Anthony, Caylee's grandfather, screamed as he moved toward the reporter. "Shut up."

Cindy Anthony stepped between her husband and the reporter. She then said the media have hampered tips from the public before walking off.

"That is the reason why I got a phone call at 11 p.m. last night and the lady was crying because of that kind of stuff on the news that she held back for four weeks calling in a tip because she was afraid and they spotted Caylee again," Cindy Anthony said.

George and Cindy Anthony spent 45 minutes on a video conference call with their daughter at the jail. Both left the Orange County Jail without comment.

Mom Stopped Mentioning Caylee

An interview with a former roommate of Casey Anthony's boyfriend shed some light on how the woman acted while her daughter was missing and before her mother called the authorities.

A man named Clint House -- a former roommate of Casey Anthony's boyfriend, Tony Lazarro -- spoke to Fox News about the woman's demeanor.

"Between June 16 and July 1 when you moved out, was Casey still coming to see Tony and spending the night?" Fox News anchor Greta Van Susteren said.

"Yes, it became more frequent and being almost every single night she was staying there," House said.

"Do you remember that week, right after Father's Day?" Van Susteren asked. "Anything unusual that week?"

"Nothing unusual besides the fact that Caylee was never there anymore," House said. "We always asked where Caylee is at, (and she'd say) 'Oh, she's with the grandparents or she's at the beach with the nanny. That didn't strike me as unusual at the time. Other than that, nothing."

House continued to say that at a certain point Casey Anthony stopped mentioning Caylee even when they asked about her.

He said looking back at the events, some of Anthony's behavior is troubling.

"Wouldn't you be surprised if someone who was hanging out with you and your friends, all of the sudden her daughter is missing and she is out partying?" House said.

House said Casey Anthony claimed she went to work every day and that she was going back to school.

He said she told him the child's father was on the way to Caylee's birthday party and was killed in a car crash but added that he had no way of knowing whether or not she was lying.
