John Gilbert Getty, a grandson of billionaire oil tycoon J Paul Getty, has been found dead in a hotel room in San Antonio, Texas. The death of the 52-year-old composer, who was the heir to a $5 billion fortune, is the latest tragedy to be suffered by the Getty family whose history has been marked by drug addiction, tabloid scandals, legal disputes, an abduction and several premature deaths. It is unclear how Mr Getty died, although foul play is not suspected. A post-mortem examination is due to be held. The death of Mr Getty, who had a 25-year-old daughter, was announced by a family spokesman. 'With a heavy heart, Gordon Getty announces the death of his son, John Gilbert Getty,'' the statement read.
