It has been revealed today for the first time that Christopher Halliwell, who admitted murdering Sian O'Callaghan, has escaped justice for a second murder because of a police error. The 48-year-old taxi driver was jailed for life today for killing Ms O'Callaghan after pleading guilty in court.
However, Halliwell was also accused of murdering Rebecca Godden during the course of the Wiltshire Police investigation. The charge was withdrawn following a ruling by a High Court judge - even though Halliwell had led police to Ms Godden's body.
Detective Superintendent Steve Fulcher, who was leading the investigation into Sian O'Callaghan's disappearance, breached police guidelines governing interviewing of suspects. He did not caution Halliwell and denied Halliwell a solicitor.
Police have vowed to get justice for Rebecca Godden.
