Theories surrounding Jones's death developed soon afterwards, with associates of the Stones claiming to have information that he was murdered. According to rock biographer Philip Norman, "the murder theory would bubble back to the surface every five years or so". In 1993, it was reported that Jones was murdered by Frank Thorogood, a builder who was doing construction work on the property. He was the last person to see Jones alive. Thorogood allegedly confessed the murder to the Rolling Stones' driver Tom Keylock, who later denied this. The Thorogood theory was dramatised in the 2005 movie "Stoned". Thorogood is alleged to have killed Jones in a fight over money; he had been paid £18,000 for work on Cotchford Farm but he wanted another £6,000 from the musician. The killing is alleged to have been covered up by senior police officers when they discovered how badly the investigation into Jones's death had been botched by the local police.
