Marion Jones says she did not deserve a prison term for lying about steroid use and involvement in a drugs fraud case.Jones, 35, who won three gold medals at the Sydney Olympics, was given a six-month prison sentence in January 2008."I know I broke the law and committed a crime by lying," the former fastest woman in the world told Inside Sport."My reputation, fame and fortune was lost. Learning that lesson would have benefitted society more than putting me away for six months."During her sentence, Jones spent six weeks in solitary confinement and served two years' probation both for lying to federal investigators about using performance-enhancing drugs and a separate cheque fraud case involving her former boyfriend, sprinter Tim Montgomery.Jones won five medals in Sydney, although it emerged during the 2000 Games her then-husband, shot-putter CJ Hunter, had failed a drugs test prior to the competition.Jones then fell foul of a major investigation into the manufacture of performance-enhancing drugs.In court in 2007, she admitted to steroid use between September 2000 and July 2001, and also lying to the federal inquiry in November 2003 over the matter.As well as going to jail, Jones was stripped of her Olympic medals, while her records were erased from the history books.The disgraced sprinter insisted that she had no idea she was taking any banned substances when she won her medals in Sydney, adding that it was only in 2003 that she realised what she had taken."In 2000, I had no idea that I had been given something illegal," stated Jones, who now speaks to young people about the mistakes she made."At that point, I knew that I had just worked hard and I was blessed with an enormous amount of talent."And she insisted she would still have had a chance of glory in Sydney, even if she had not been taking drugs."Even before I was given the drugs, in 1998 I set my personal bests and my success as a junior gets overshadowed by what happened subsequently," suggested the mother of three.Credit: BBC
