Twelve years ago, the tranquil expanse of Nevada was shattered by a grisly crime that sent shockwaves through the state.  A couple was brutally murdered in their home, their five-year-old stepdaughter left unconscious, and their eight-year-old stepson found drenched in blood, the only apparent survivor.  Mounting evidence pointed to the young boy as the cold-blooded killer. Over the ensuing twelve years, the boy, incarcerated in Nevada's maximum-security prison, masterminded the deaths of dozens more, using methods as ingenious as they were horrifying.  Today, the notorious murderer faces his final judgment—execution.
