JonBenet murder: Questions raised over 'confession'

For a moment, it seemed the decade-old mystery surrounding the slaying of a child beauty queen had been solved. But authorities have cautioned against rushing to judge the schoolteacher who made a stunning confession that he killed JonBenet Ramsey.

For now, the only public evidence against John Mark Karr is his own words. And questions have already been raised about the details of his story, including whether he drugged the six-year-old girl, sexually assaulted her or was even in Colorado at the time of the slaying.
