Simon Levy was already known to police as a serious sex offender when a series of failures left him free to kill two women in London, despite warnings that his offending was escalating and that he posed a 'high risk of reoffending'.
The 40-year-old was convicted at the Old Bailey on Friday of murdering Carmenza Valencia-Trujillo, 53, and Sheryl Wilkins, 39, in separate attacks in 2025. The case has since exposed a chain of errors involving the Metropolitan Police, British Transport Police and the Crown Prosecution Service, with all three acknowledging failures connected to Levy.
