Who's There?

In 1982, a quiet town in Kansas was rocked by the murder of a young banker named David Harmon who was bludgeoned to death in his bed. His wife told authorities that it was a home invasion. Investigators suspected that she was having an affair with a family friend and that the two were involved in David’s murder. But the case went cold until nearly 20 years later, armed with new forensic technology, police zeroed in on the couple. “48 Hours" Correspondent Hannah Storm reports.
