Born to Kill - Season 1

Over a period of about twenty years Fred and Rose West abducted, tortured, raped and murdered an unknown number of girls, many of whom lay buried in the garden until the police dug them up. What motivated West to commit such terrible crimes? Was he born evil or did his upbringing make him this way? Did he do it for sexual kicks? Or, as some allege, did he supply the sacrificial victims to a black magic coven?

The world’s most prolific killer, Shipman is estimated to have killed 275 people, but the actual figure will never be known. The 57-year-old GP was given 15 life sentences to run concurrently for the murders, and four years for forging a will, but hung himself in his cell after he was sentenced. He always denied his crimes. When the police began investigating Dr Harold Shipman in September 1998 they struggled to understand him. How could a GP who was trusted and respected by more than 3,000 patients also be a killer who struck time after time with no obvious motive? The coroner speculated that ‘the only valid possible explanation for it is that he simply enjoyed viewing the process of dying and enjoyed the feeling of control over life and death, literally over life and death …’

Two black Americans, John Allen Muhammad, 42, a veteran of the Gulf War in 1991, and his stepson John Lee Malvo, 17, were convicted in 2004 of being the ‘Washington sniper’, who had been terrorizing America over a period of three weeks. Police found a gun in the suspects car - the criminals had supposedly shot it 13 times. Ten innocent people were killed, and three were wounded. Police also found a scope and a tripod. The criminals probably shot the victims without even leaving the car, as it has an opening in the trunk that allows people to lie hidden and shoot the victims. Experts unanimously agreed that it was John Allen Muhammad who was the force of the criminal tandem. What were the motives of these men, and was one ‘guiltier’ than the other? Psychologists suppose that John Allen Muhammad is non compos mentis, but find it difficult to explain why the stepson acted in the same way…

Some say his motivation lay in his family background and upbringing. Ivan Milat grew up as one of 14 siblings, a close-knit family who didn’t mix with others. They were surrounded by guns amidst an ethos of lawlessness and unbreakable family loyalty. Did he kill alone? One of his siblings, Boris, broke the bonds of rigid family loyalty to speak out against the convicted killer. He said it was likely there were more of his victims that haven’t yet been found…
