A bounty hunter who arranged the release of Casey Anthony, the mother of missing toddler Caylee Anthony, said today that her bond will be revoked on Saturday and she will be returned to the Orange County, Fla., jail.
Leonard Padilla said he would ask his associates to revoke Anthony's $500,000 bond.
Padilla also said that, in light of preliminary air sample tests that reportedly show a decomposing body was in Anthony's trunk, he now believes that Anthony accidentally killed her daughter, who has been missing since mid-June.
"I think it was an accident," he said. "Her friends called and said she wouldn't have harmed her, but if she did, she would have freaked."
Padilla, a self-styled celebrity bounty hunter, a few weeks ago offered to bail 22-year-old Anthony out of jail, saying that he thought he could convince her to cooperate in the search for Caylee. Padilla has said Anthony has not cooperated since her release.
A law enforcement source confirmed to ABC News that air sample tests taken from Anthony's trunk allegedly revealed evidence of human decomposition. The results were first reported Wednesday.
Police last month said hairs the same length and color as Caylee's were found in the trunk of the car and Casey Anthony's mother, Cindy Anthony, said in a 911 call that the car smelled like there had been a dead body in it.
Cindy Anthony has since retracted those comments, saying the smell could easily have been from garbage in the car.
A family spokesman said that Cindy Anthony was meeting with authorities to search for Caylee, whom she believes is still alive. "There has been nothing definitive," Larry Garrison said of the air sample tests.
For Anthony to be returned to jail, the local bail bondsman who bailed Anthony out of jail last week must take her into custody and return her to the Orange County, Fla., lockup.
Anthony has said her daughter has been missing since mid-June, but she didn't report it until more than a month later. She has not been charged with her daughter's disappearance, though police have said she is a "person of interest" in the case.
She faces charges of child neglect, making false statements and obstructing an investigation for allegedly lying to the police.
Earlier this week, prosecutors released more than 400 pages of documents, including police reports and transcripts of interviews, that portray Anthony as troubled and a habitual liar. The documents also allege that Anthony wanted to give Caylee up for adoption before she was born but that her mother dissuaded her.
According to the documents, Anthony told police that she left the child with her baby sitter, then couldn't find them when she returned from work. But, no one had lived at the address Anthony gave for the babysitter for months.
Anthony also claimed to work for an Orlando theme park, but investigators say she had not worked there in months. The documents include a poem Anthony wrote on July 7, eight days before she reported her daughter missing: "What is given, Can be taken away. Everyone lies. Everyone dies."
Also this week, the sheriff's department confirmed that a sheriff's deputy had been fired for reportedly lying about his relationship with Anthony.
Anthony Rusciano was fired Aug. 22 after investigators found evidence on Casey Anthony's computer that the two had a relationship. A department spokesman would not comment on the nature of their association, but said it went "beyond a casual relationship."
Earlier, Rusciano reportedly had denied the relationship, saying he had only met Anthony briefly at a party, according to an Orange County Sheriff's Department memo.
A department spokesman said investigators do not think Rusciano is involved in Caylee's disappearance.
