In August of 1999, Rosemary Christensen vanished from the Belleair, Florida condo she shared with her husband Robert. The disappearance was first reported to police by Rosemary's co-workers when Rosemary failed to show up for a work party. Immediately, Robert was a suspect--he had a violent past and relationship with Rosemary had been on the rocks. But he was forthcoming with police and seemed to be cooperating. So where it Rosemary? It would be 10 years before anyone found out.
