The man accused of killing a California woman and kidnapping at least one of her children is on the run tonight. Police issued an Amber Alert for her two children, 16-year old Hannah Anderson and eight-year old Ethan Anderson. There are growing fears tonight, Ethan may have been killed along with his mother. Hannah's father had a desperate message for his daughter, "If you have a chance, you take it, you run. You'll be found." Anderson spoke with former FBI profiler Mary Ellen O'Toole, and Marc Klaas, founder of the KlassKids Foundation who had advice for someone in Hannah's situation.
