The couple's daughter, 22-year-old Casey Anthony, has been charged with first-degree murder and faces life in prison if convicted of killing Caylee. She has pleaded not guilty.

The Orlando tot was last seen on or around June 16, but her mother did not report her missing until July.

The child's grandmother first called authorities in July to say she hadn't seen Caylee for a month and her daughter's car smelled like death.

Caylee's remains haven't been found, despite numerous searches.

Anthony told authorities she left her daughter with a baby sitter in June and the two were gone when she returned from work. She says she spent the next month trying to find Caylee and didn't call police because she was scared. Investigators have repeatedly said they don't believe Anthony's story.
