Kaila and Drew Schock lived through a double tragedy. First, their 18monthold son Ezra drowned in a pond at his grandmother's house. Then, less than a year later, their 8monthold daughter Uri lost her life after being left in a hot car for hours by the same grandmother. Now, Tracy Nix has been charged with aggravated manslaughter in the death of baby Uri. The grieving parents say they want justice even if it means sending Nix to jail.
