Laci Peterson went missing on December 24, 2002 from her Modesto, California home she shared with her husband, Scott Peterson. Laci was happy, pregnant, and with no known enemies. During her disappearance, Scott came across as nonchalant with the police drawing their attention. When it was revealed he was having an ongoing affair, all  suspicion fell on him. Did Scott kill his wife and unborn child or did his arrogant demeanor and reckless behavior result in his conviction?
