Funeral Held for Slain Idaho College Student Ethan Chapin

The grieving mother of one of the four slain Idaho university students was choking back tears at his funeral. Stacy Chapin says her son Ethan Chapin was "one of the most incredible people you will ever know." Pressure is mounting on cops for a breakthrough, but former FBI Assistant Director Bill Swecker says police may be on the wrong track. He believes that the murders are the work of a predator.
