Two Burmese men have now confessed to murdering British backpackers Hannah Witheride and David Miller on the island of Koh Tao, according to police. Officers arrested three men who were pictured riding a moped away from the scene of the killings on September 14. Two have admitted their guilt, but the third still denies any involvement. It is not known which of the men in the CCTV image have confessed. After the first admission of guilt, a credible source within the police ranks on 'murder island'  told MailOnline that he had been called by a senior officer who said: 'We have a confession. We have a suspect in custody. We are very confident we have our man.'
