Casey Anthony, left, mother of missing 3-year-old Caylee Anthony, arrives Thursday at her attorney's office with bodyguard Robert Dick in Kissimmee, Fla. A bounty hunter who helped free Casey Anthony wants his associates to withdraw her bail, which could force her to return to jail. Detectives met with prosecutors Thursday to discuss FBI lab tests, which showed a decomposing human body had at one time been in Casey Anthony's car.

ORLANDO, Fla. — A bounty hunter who helped free the mother of a missing Florida toddler wants his associates to withdraw her bail.

That could force Casey Anthony to return to jail unless she can find another way to cover the $500,000 bail.

Anthony was freed last Thursday. Her family said that would help find missing 3-year-old Caylee Anthony.

But bounty hunter Leonard Padilla says the 22-year-old mother hasn't cooperated since her release.

Caylee hasn't been seen since June but wasn't reported missing until a month later. Prosecutors say Casey Anthony is a person of interest in her disappearance but she only faces charges of child neglect, obstruction and making false statements.

Detectives were meeting with prosecutors Thursday to discuss FBI lab tests in the case.
