You probably remember the case of Elizabeth Smart of Salt Lake City who was kidnapped from her home seven months ago. The 14-year-old girl has never been found. This Friday, 48 Hours Investigates goes inside the police investigation, getting exclusive access and new information about the case which is still very active. One can only imagine what Ed and Lois Smart have been going through since the kidnapping. Their courage has been an inspiration to their children. Correspondent Jane Clayson has the first interview with Elizabeth's brothers and sister. Jane also reports new information that the kidnapping last June didn't happen the way everyone thought. We're working right up to Friday's deadline, so I can't give you too many details now. But believe me, it's definitely worth watching Friday night.
