It's a puzzling case -- and an urgent one: A killer, filled with chilling contradictions. He strikes in public places, but disappears without a trace. He's deadly one moment, but strangely polite the next. And his targets? Mothers in their SUVs, out for a day of shopping at the mall. Only one of his victims has survived -- and now she may hold the key to his capture. You'll hear her tell a harrowing tale of kidnap and survival. NBC's Dennis Murphy reports on "Terror at the Mall."
Also: For nine years it was a mystery, the strange disappearance of a woman who was adored and admired. Worldly, lovely, wise, Rosemary Christiansen led a sophisticated life as a diplomat's wife, then left it all to start anew in America. A giant leap of faith she made for love. So when she vanished, her circle of friends wondered: Did she leave this new life, too? According to investigators, that's exactly what someone wanted them to think. NBC's Keith Morrison reports on the case of "Rosemary and the Motorcycle Man."
