Prime SuspectsInvestigators working on the disappearance of toddler Caylee Anthony have named the 3-year-old's mother, Casey Anthony, a suspect. Casey was arrested by police in July and was released on bail but still remained a "person of interest" in the case due to evidence of human decomposition in the trunk of her car, as well as chloroform residue. Casey has been uncooperative with the investigation, one element cited as a reason for her now being named a suspect. [CNN]
