Missing Mom Stacy Peterson’s Sister Says She Found Her Body in Illinois Canal

An Illinois woman says she's found the body of her sister, Stacy Peterson, missing since 2007. Stacy was the wife of cop Drew Peterson, the prime suspect in her disappearance. He's behind bars for the murder of another ex-wife. Cassandra Cales says images, first seen on NewsNation, show skeletal remains 25 feet below the surface. She found what she believes is the body using a remote-operated sonar vehicle but says the authorities are dismissing her discovery.
