A 'predatory monster' who murdered two women, raped and almost killed a third while he was on bail for multiple sex attacks faces life behind bars today.Simon Levy will be sentenced for the murders of Carmenza Valencia-Trujillo, 53, and Sheryl Wilkins, 39, and the rape and near-fatal suffocation of a third woman.Following his conviction at the Old Bailey last week it emerged that Levy had been preying on women for years, with many of his offences occurring while he was on bail.Earlier this year, the 40-year-old was convicted of 13 sexual assaults between 2018 and 2025.Detectives believe Levy could have been carrying out daily attacks for years, escalating from groping women on the London Underground to rape, suffocation and eventually murder.Now as Levy potentially faces the rest of his life behind bars after being convicted of murder and rape, it can be revealed how police and probation missed a monster in their midst.In an appalling betrayal of victims, the convicted sex offender was repeatedly released on bail despite being repeatedly arrested on suspicion of sexual assaults and even murder.Although he had a shocking record for sexual violence dating back to 2018, British Transport Police (BTP), the Metropolitan Police and magistrates all failed to appreciate the danger he posed, releasing Levy on bail four times leaving him free to daily stalk the transport network claiming countless victims.
