Caylee's mom could leave jail soon, police say

(CNN) -- A Florida woman suspected in the disappearance of her 3-year-old daughter is likely to leave jail Friday after somebody posted $500,000 bond, police said.

Casey Anthony could be released from jail mid-morning Friday, according to a news release from the Orange County Corrections Department.

"I have verified that the jail is now in possession of paperwork provided by the Clerk of the Court that will satisfy the $500,000 bail on the child neglect charge. Bail has already been satisfied on the other 11 charges," the release said.

The story of Anthony and her missing daughter has garnered national headlines, been the nightly fodder of cable TV crime shows and brought a stampede of reporters to stake out Anthony's Florida family home.

Anthony reported her daughter, Caylee, missing in July, a month after the last known sighting of her. Anthony told police that a baby-sitter kidnapped Caylee, but police found inconsistencies in her story, according to police reports.

Police jailed Anthony at that time for child neglect, making false official statements and obstruction of justice, but a bounty hunter paid the bond that let her out of jail.

She was arrested again August 29, this time on charges of forgery, fraudulent use of personal information and petty theft.

Investigators have also uncovered some damaging evidence in the case.

Investigators said they had found evidence of human decomposition in the trunk of Casey Anthony's car. Law enforcement sources also suggested that a strand of hair found in the trunk of the car was Caylee's.
