David Middleton is the only convicted serial killer in American history who is also an ex-Police Officer. Once a respected Miami Police Detective, he now awaits execution on death row in Nevada. Middleton preyed on women he met while working as a cable television installer after having been fired from the Miami Police Department. While serving on the Miami PD, Middelton was arrested for sexual assault and kidnapping and subsequently fired. He brutally tortured his victims in a makeshift chamber of horrors before killing them, but the heinous crimes he was convicted of are just a part of this story. The unsolved murder of Buffy Rice Donahue and her surviving family wait with indignation as fingers point to local law enforcement officials who let Middleton slip away to go on his last killing spree before getting captured in Reno.
