Career
He has one child with sprinter Marion Jones.

Personal Life
Montgomery did not qualify for the 2004 Summer Olympics, finishing seventh in the final of the United States Olympic trials. Before the trials, however, he was charged with using illegal performance-enhancing drugs, by the United States Anti-Doping Agency (USADA). While he has not returned a positive drug test, according to press reports he testified to the agency that he, along with a number of other prominent athletes (including baseball star Barry Bonds), obtained steroids and human growth hormone from BALCO, a laboratory near San Francisco. The USADA sought a four year suspension on Montgomery, who appealed to the Court of Arbitration for Sport (CAS). On 13 December 2005, the CAS found Montgomery guilty and imposed a two year ban. On top of the ban, all of Montgomery's results and awards since 31 March 2001, including his former world record, had also been stripped.[1] After the ban was announced, Montgomery announced his retirement.
The investigation also implicated his former partner Marion Jones, winner of the women's 100 metres at the 2000 Summer Olympic games.
