She was also an accomplished high-school basketball player, winning California’s Division I Player of the Year award in 1993. She attended the University of North Carolina at Chapel Hill on a basketball scholarship, and in 1994 she helped the women’s basketball team win the national title. Jones decided to sit out the 1995–96 basketball season in order to focus on track and on the 1996 Olympics in Atlanta.

A series of foot injuries, however, prevented her from trying out for the U.S. Olympic team. She then returned to basketball, and in 1997 she was named the Most Valuable Player of the Atlantic Coast Conference Tournament.

Through much of her career, Jones was suspected of using steroids. In 2003 a federal investigation into illegal steroid distribution by the Bay Area Laboratory Co-operative (BALCO) led to allegations by BALCO founder Victor Conte and Jones’s ex-husband, C.J. Hunter, that the sprinter used banned substances. Jones, who had never failed a drug test up to that time, denied the allegations.

In 2006 she tested positive for a banned substance but was later cleared by a follow-up test. The following year, however, she pleaded guilty to lying to federal investigators about her drug use and admitted to having taken steroids. In November 2007 track and field’s international governing body—the International Association of Athletics Federations—annulled all of Jones’s results from September 2000 on, including her Olympic titles.

The International Olympic Committee officially stripped Jones of her five medals from the Sydney Games the following month. In January 2008 she was sentenced to six months in prison for providing false statements to federal investigators about her steroid use and for her involvement in a check-fraud scheme.

In an attempt to revive her long-dormant basketball career, Jones signed with the Tulsa Shock of the Women’s National Basketball Association (WNBA) in 2010 but was cut 15 games into the 2011 WNBA season.
