NEW YORK � December 10, 2008 � One of the most disturbing stories of this past year began in July when the disappearance of an adorable 3-year-old, Caylee Anthony, made national headlines. Since then, its been splashed all over the tabloids and spun-dry endlessly on cable new shows, fueling the kind of public frenzy usually reserved for celebrities. As the search for Caylee continued throughout the summer months, her mother Casey's already troubling involvement became even more suspicious, eventually leading police to charge her with the unimaginable: murder.
