Casey Anthony to Be Released From Jail

Sept. 4, 2008 — -- The mother of missing toddler Caylee Anthony is expected to be released Friday morning for the second time in two weeks.

The Orange County, Fla., Corrections Department said Casey Anthony will probably be released by midmorning Friday.

Court documents show that Anthony's parents, George and Cindy Anthony, put up part of the collateral for her release from jail. The source of the money was not immediately clear. Joe Von Waldner, the Orlando bail bondsman who posted Anthony's bond, told ABCNews.com that he was working on behalf of a surety company, which he declined to name. Von Waldner said he was working with another bail bond company called MacDonald Bail Bonds, which declined to comment.

Anthony's release will be the second time in a matter of weeks that the 22-year-old mother has been freed from jail. A California bounty hunter arranged for bond to be posted for Anthony, who was being held on charges including child neglect and making false statements, and she was released last week.

Anthony returned to jail last weekend after her bond was revoked. The bounty hunter, Leonard Padilla, had said that Anthony had been uncooperative since her release from jail.

On Thursday, the Orlando Sentinel reported that traces of chloroform reportedly were found in the trunk of a car driven by Anthony.

The paper, citing unidentified sources, said that preliminary FBI tests found the chemical in Anthony's car trunk. Law enforcement sources had previously told ABC News that air-sample tests from the trunk found evidence of human decomposition.

The paper also reported that there was evidence that Anthony may have searched for information about the chemical on her computer.

Chloroform, once used as an anesthetic, can cause a person to pass out. High doses can be fatal.

Anthony has been called a "person of interest" in the disappearance of her daughter, but has not been charged in connection with Caylee's disappearance.
