LONDON , England -LRB- CNN -RRB- -- British police are reviewing the death of Rolling Stones founder Brian Jones , 40 years after the hard-living rocker was found dead in a swimming pool . An autographed photo of Rolling Stones founder Brian Jones who was found dead in July 1969 Police in Sussex , in southern England , have confirmed they are examining documents given to them by an investigative journalist who has been researching events surrounding Jones ' death . Scott Jones , who is not related to the musician , has spent four years reviewing the evidence and speaking to key witnesses in the case . In an article published in the Daily Mail in November 2008 , Jones wrote , `` I 'm convinced Brian Jones ' death was not fully investigated . The only question that remains is why ? '' Brian Jones ' body was found in the swimming pool after a party at his home in Cotchford Farm , East Sussex in July 1969 . He was 27 . An inquest returned a verdict of death by misadventure , despite post mortem results showing he had not taken illegal drugs and had only consumed the alcoholic equivalent of three and a half pints of beer . One of the most popular conspiracy theories that followed was that Jones was murdered by his builder , Frank Thorogood . The theory gained credence after Thorogood allegedly confessed to the killing before his death in 1993 . The storyline formed the basis of the 2005 film `` Stoned . '' Sussex police told CNN they could not say how long it would take to review the new material , nor whether it could lead to a full investigation . There have been repeated calls for closer examination of the case since Jones ' death , which came just three weeks after he left the Rolling Stones . His drinking and drug-taking had taken a toll on his health and the band , and in 1969 Jones announced he was leaving . In a statement he said , `` I no longer see eye-to-eye with the others over the discs we are cutting . '' Last year , Scott Jones published an article containing contents of an interview he conducted with one of the people present at Jones ' home on the night of his death . In the article , published in the Daily Mail , Jones ' said Janet Lawson , the girlfriend of Rolling Stones tour manager Tom Keylock , gave him a version of events that contradicted her official police statement . She is reported to have called her original statement , `` a pack of lies ... total rubbish . '' Lawson 's revised version of events is among the documents Jones has supplied to Sussex police . It is also believed to include previously unseen files released by the Public Records Office . Lawson died of cancer soon after telling Scott Jones her new sworn testimony .
