Missing in Time

what happens

A young woman was reported missing after a fight with her husband. She was presumed to be dead and her husband was the prime suspect. Police were suspicious of a secondary suspect when he reported a suspicious fire in his car. Two tiny drops of blood were found in the burned interior. Traditional DNA testing was difficult, since there was no body for DNA comparison. But a tiny clue inside the suspect's watchband and a popular television show helped solve the case.
