JonBenét Ramsey: Race Against Time, Who Is ‘Unknown Male 1'?

Sinopsis

It remains one of the country's most haunting unsolved murders: 6-year-old JonBenét Ramsey found brutally murdered in her Boulder, Colorado, home. Thirty years since the horrific crime, questions continue to surround her death. In an all-new "20/20," ABC News anchor Diane Sawyer reports on the investigation. Sawyer first covered the case with a 1997 exclusive ABC News tour of the Ramsey home and interview with JonBenét's pediatrician. Sawyer and chief investigative correspondent Aaron Katersky examine new evidence and secure 19 exclusive and rare interviews with nuclear family members and people closest to the case, some stepping in front of cameras for the first time.
