Becky Watts' Killer Sobs While Giving Evidence

The stepbrother of murdered teenager Becky Watts has broken down in court while giving evidence in his own defence. Nathan Matthews, 28, struggled to compose himself and slumped in the witness box as he was asked to confirm that he killed the teenager. Earlier, Matthews admitted he planned to kidnap Becky, but insisted his girlfriend Shauna Hoare, 21, played no part in the plot to kidnap his stepsister.
