A fireman's fiancé (DeLane Matthews) asks Lilly to help prove that a convicted felon, about to be paroled on an unrelated crime, is responsible for the murder of the fireman's first wife. The young mother was killed by a homemade bomb packed in a laundry-detergent box shortly before she was to testify in court against a man who exposed himself to her.

- When Lilly asked Louie about the oldest crime scene fresh evidence was ever discovered at, Louie responds "Lucy, six thousand years old. Someone smashed her skull in." Presumably Louie was either kidding or confusing Lucy (a 3 million year old hominid skeleton), with Ötzi the Iceman (a European mummy preserved in ice since 3300 B.C., who had suffered several wounds, including a blow to the head).
