A federal Bureau of Prisons spokeswoman said Jones, 32, was released at 9 a.m. ET Friday from a halfway house in San Antonio after serving most of her six-month sentence for lying to federal investigators about her use of performance-enhancing drugs.
For years, the track star denied using performance-enhancing drugs. But in October, she pleaded guilty to two charges of perjury and was sentenced in January by a federal judge in New York. Jones reported to prison on March 7.
She admitted that she had lied to federal investigators in 2003 when she denied knowing that she took the banned substance tetrahydrogestrinone (THG), known as "the clear," before the 2000 Olympics.
An admitted steriod dealer testified that he gave Jones a cocktail of steriods before the Games in Sydney.
In 2007, Jones was stripped of the Olympic medals, three of which were gold, and all of her performances as of Sept. 2000 have been erased from the record books.
