Casey Anthony was not serving probation while she was in jail awaiting her murder trial and she must report to a probation office in Florida by noon Friday, an appeals court has decided. The court ruled that the 25-year-old cannot "take advantage" of an administrative error to dodge the sentence from a check fraud conviction, CNN reports. Anthony, who has been in hiding since her release from jail last month, will be required to get a job and stay in Orange County, Florida, unless probation officers grant her permission to leave.
