Pandora's Box: Unleashing Evil

Storyline

It's rare when a law enforcement case turns out to be routine. More likely, the crime scene represents just the tip of the iceberg. "Dungeon of Dread" -- the premiere episode of "Pandora's Box: Unleashing Evil" -- details how a shoplifting case jumpstarts an investigation into two of California's deadliest, most depraved serial killers, exposing a twisted tale of terror and evil unlike anything investigators have ever encountered. It's just one of many actual cases uncovered in the hourlong series, all of which get more sordid as every piece of evidence is examined.
