20/20: Steve's Legacy/Missing Nina/Words That Wound

Barbara Walters interviews Terri Irwin again, one year after their first interview when her husband, crocodile hunter Steve Irwin, had just passed away.

Then, the mystery of a 31 year old mother of two who vanished a year ago. Her husband has been charged with her murder, but a body is nowhere to be found. A jailhouse interview with him and with her best friend. Finally, a baptist church whose messages of hate cost them $11 million dollars in damages by a jury for disturbing a soldier's funeral.
