About Between Black and Blue
This true crime documentary series explores the extraordinary story of two New York City detectives who are convicted of the sensational 1975 murder of a Denver businessman, their decades-long fight to clear their names, and the hunt for one of the confessed gunmen who may hold all the answers, a man placed into witness protection by law enforcement over forty years ago.
