Cold Case: Season 2, Episode 23

2 - 23: The Woods

Lilly tracks a serial killer who eluded her months earlier. The chase begins after nine human skulls are found in the backyard of an abandoned house where a blind woman, whose killer was never found, was murdered in 1972. The woman's 12-year-old son witnessed the crime, and now is believed to be a mass murderer. Making the case more eerie is the fact that the killer knows intimate details about Lilly's life, which he tries to use against her.
