A new, three-part show is putting the spotlight back on the death of Florida toddler Caylee Anthony and the 2011 acquittal of her mother, Casey Anthony.
"Casey Anthony: An American Murder Mystery" on Investigation Discovery has gone back and interviewed investigators and others, including Casey Anthony's parents, about the case that gripped the nation. The show looks at the holes in Anthony's story that led to her being charged with murder.
Anthony has always said she's innocent and doesn't know how her daughter died.
Part one aired Sunday. Part two airs tonight at 10 p.m. EST.
