Sealed with a Kiss (2x10)

Air date: Dec 18, 1997

For more than a year, angry, hateful letters were sent to a first grade school teacher in a small town in Pennsylvania. When scientists analyzed the letters, they found evidence that the stalker knew a lot about the victim - more, in fact, than anyone could possibly have imagined. DNA analysis would eventually help seal the perpetrator's fate. Medical Detectives, Season 2, Ep 10.
