Infamous for the murder of schoolgirl 13 year old Milly Dowler, Levi Bellfield is one of the UK's most despised serial killers. Linking him to further crimes for which he has not yet been convicted proves to be one of the most complicated cases that Professor Wilson has studied. Bellfield had multiple signatures and seemed to be on a mission to destroy young women in any way that he could.

PhD criminology student Stephen Griffiths, self dubbed 'The crossbow cannibal' struck shock and fear into the nation when admitting to killing, dismembering and eating parts of three women between 2009 and 2010. But Professor Wilson believes that this twisted killer, who had been addicted to murder since a very young age, has yet to be convicted of all of his hideous crimes.

When the murderer of Rachel Nickell was finally unmasked by DNA as the psychotic multiple killer and serial rapist Robert Napper, the country was in shock. Famously Colin Stagg had been tried but freed under much public scrutiny of forensic psychologists Paul Britton's methods and so it seemed an end had finally come to this horrific case.
