Episode Recap: The Missing

Each year in America, more than 600,000 people are reported missing. Some are doggedly searched for by friends and family members; others seem to simply disappear, unfound and unlooked for. In this episode, Lisa Ling meets women on both sides of the search: A woman who disappeared for two months as the victim of a notorious kidnapping, and a mother still searching for her daughter who went missing three years ago.
