ORLANDO, Fla.- Casey Anthony returned home from jail Friday to face renewed protests over the disappearance of her 3-year-old daughter and new questions about whether her family is making money off the case.

The 22-year-old walked out of the Orange County Jail in Florida at 10:13 a.m. after being fitted with an ankle bracelet to monitor her movements. Surrounded by defense attorney Jose Baez and two bodyguards, she disappeared into a black SUV and motored to the home of her parents after posting $500,000-plus bail on charges of child neglect, giving false statements and passing bad checks.

Sporting a black baseball cap and white T-shirt featuring a picture of missing Caylee Marie, Anthony kept her head down and said nothing as she walked out of jail. On arriving at her family’s east Orange County home, the SUV pulled into the garage and quickly disappeared from view.

About a dozen people waited with reporters across the street from the Anthony home – many of them suspicious that the young woman knows what happened to her child.

A 2-year-old stood quietly at her mother’s feet, holding onto a sign that read, “How could you kill a baby like me!!!”

Amber Railing, the toddler’s mother, said she doesn’t understand Anthony’s behavior since Caylee disappeared.

“She shows no emotion,” Railing said. “If it was my child and I was sitting in jail, I’d be ranting and raving until they let me out of jail to find my child.”

Caylee was reported missing July 15, several weeks after she supposedly disappeared. Anthony has told investigators that a baby sitter took the child, but sheriff’s investigators maintain she is lying. The lead investigator in the case has said evidence in the trunk of the mother’s abandoned car suggests the presence of a body at one time – and that it likely was Caylee’s.

The case has attracted national attention, including a story Friday night on ABC’s 20/20. At least one protester and several sources close to the case speculated Friday that the network had offered the Anthonys money for an interview. ABC denied those reports.

Casey Anthony had been free on bail until last week, when deputy sheriffs arrived to arrest her on charges that she stole and then used checks belonging to a friend. She returned to jail amid the jeers of protesters who had appeared outside the house.
