(CNN) -- A bounty hunter said Thursday that he will revoke the bond of a Florida woman suspected in the disappearance of her toddler daughter as new evidence suggests the possibility of a sad outcome in the case.
A law enforcement source with knowledge of the case told CNN affiliate WKMG reporter Jessica D'Onofrio that DNA evidence had matched a strand of hair found in the trunk of a car linked to Casey Anthony with her daughter, Caylee.
On Wednesday, a law enforcement source close to the investigation told CNN investigators have also found chemical evidence of human decomposition in the trunk.
Police were alerted of the car by Anthony's mother, Cindy Anthony. At that time, Cindy Anthony told authorities that it smelled as if there had been a dead body in the trunk. Watch what FBI tests found »
Cindy Anthony has since said she believes that her granddaughter is alive.
Meanwhile, Leonard Padilla told CNN Headline News' "Nancy Grace" that he is revoking the bond of Casey Anthony because of "safety issues."
Padilla said he fears that his co-workers, who are maintaining surveillance on Anthony, will be injured by the large crowds of media members who have been staking out her home. Watch more on what the test results mean »
"I am not Britney Spears," Padilla said, referring to the crowds of reporters his staff members have had to dodge. "She is going back to jail Saturday."
Padilla also said that his employees had received death threats.
Three-year-old Caylee Anthony has not been seen since early June, but her mother, Casey Anthony, did not report her missing until nearly a month later.
Anthony told police that a baby-sitter had kidnapped the baby, but police found inconsistencies and lies in her story, according to police reports.
"Based on the repetitive lies that the defendant has told, we do not know with whom the child is or even if the child is alive," an Orange County Sheriff's Department detective wrote. "She continued to claim ignorance and at times laughed about the situation."
Anthony has been charged with child neglect, making false official statements and obstructing a criminal investigation and was in jail before she was bonded out by Padilla.
