33 - 13: The Tara Grinstead Mystery

Tara Grinstead was a teacher and former beauty queen when she disappeared in October 2005. But nearly 12 years would pass before investigators finally learned what happened - and now recent revelations indicate local law enforcement and state investigators may have been able to solve the case soon after she vanished. Correspondent Peter Van Sant and 48 HOURS investigate the young woman's disappearance and the quest for answers.
