20/20: Taken/Friend or Enemy?/A Memory Champ

Recently Missouri boys Ben Ownby and Shawn Hornbeck were rescued from their abductor. Now that they are home, what kind of life will they face? Jessyca Mullenberg is another kidnap victim who beat the odds. She says that she is still overwhelmed by the horrific experience, almost 12 years after her abduction. Jessyca's tale is a rare opportunity to see a child abduction through the eyes of one of the few who have lived to talk about it. Elizabeth Vargas also talks to Patty Wetterling, a mom who still holds out hope even though her son, Jacob, has been missing for 18 years; and to Trevor Wetterling, the brother who was with Jacob when he was abducted. Then, an exclusive interview, Barbara Walters sits down with controversial Venezuelan President Hugo Chavez. This is the first time he has been interviewed by an American television journalist since he was in the U.S. last fall for the United Nations and called President Bush "the devil," and since his re-election in December. Finally, Bill Ritter reports that it takes just ten minutes a day of memory exercises to help improve your memory and also protect against age-related memory loss.
