Synopsis:
The abduction and murder of three-year-old Riley Fox one of the most heart-breaking and dramatic unsolved crimes the Chicago area had seen in years. In the spring of 2004, Riley disappeared in the middle of the night from her living room couch, where she had been sleeping. She was found floating in a nearby creek, sexually abused. The tight knit Chicago suburb was devastated, especially when police announced a most unlikely suspect had confessed, her devoted father. Correspondent David Muir reports on the unimaginable crime, the confession and the claim that police were out to get Riley's father and missed important clues.
