A look at some of Europe's and America's most horrific serial killers and how bizarrely simple blunders eventually brought them to justice.

The unfortunate truth of modern policing is that despite all the DNA tests, criminal profiles and surveillance technology it's still extremely difficult to catch a killer. Random killers, who murder as a passion, can elude even the most highly trained and well equipped of police forces. Luckily, they tend to give themselves away. Killers is a documentary series that tells the surprising story of how some of Europe's and America's most horrific murderers were eventually brought to justice. It's a story of shocking crimes and bizarrely simple blunders, that takes the audience behind the worn-out stereotype of the criminal mastermind to reveal the very ordinary men who commit the most inhuman of crimes.—Sky Vision [gb]
