On 30 July, the body of a man in his late 30s was found on a waste tip in Surrey. He had been stabbed three times. His clothes, wallet and rings had been removed but his tattoos helped police identify him. He was 37-year-old George Leitch from south London, who had been reported missing by his family four weeks earlier. Tonight's programme reconstructs the events surrounding his disappearance and murder in the hope that new information will emerge. Police also need to catch a rapist who attacked and robbed a woman in London on 16 August; and they are also seeking the gang leader in an armed robbery at a Hull factory in late July.
