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.
