Casey Anthony will be staying in jail a little longer than we thought.

Although court officials said Thursday afternoon that Anthony would be released on July 13, a statement sent Thursday night corrected that date to July 17.

“After receiving the signed order this afternoon on the sentencing of Casey Marie Anthony, Orange County Corrections conducted a detailed recalculation of the projected release date,” jail public information officer Allen Moore wrote.

He added that no additional information will be released about the time and method of Anthony’s release “so as to preserve the safety of the individual and the public.”

Anthony was sentenced Thursday to four years in jail for her conviction on four counts of providing false information to law enforcement, but she received credit for time served since her 2008 arrest and good behavior.

On Tuesday, a jury found her not guilty of murder, aggravated manslaughter and aggravated child abuse in her daughter Caylee’s death.

According to a new USA Today/Gallup poll, 64% of Americans believe Anthony definitely or probably murdered her daughter. 27% of women polled said they were angry about the verdict, but only 9% of men did.

One angry woman, Michelle Crowder, has taken action, setting up an online petition for a federal law that would make it a felony for a parent or guardian not to report a missing child. The petition had over 675,000 signatures Friday afternoon. Nancy Grace will be interviewing Crowder on tonight’s show.

Lawmakers in several states, including Florida, have said they plan to draft similar laws.
