Disgraced US sprinter Marion Jones hands over Olympic medals

"She relinquished this afternoon the medals that were won unfairly at the Sydney Games," Scherr said.

"She has taken the right step and worked quickly and voluntarily returned the medals and that is a start. I think there is still a long ways to go.

"They (medals) are in the possession of the USOC and will be returned to the IOC so they can be awarded to the appropriate winners at the Olympic Games."

The 31-year-old American pled guilty Friday to lying to federal investigators and USOC chairman Peter Ueberroth said the next step would be for her to hand back the Olympic medals.

"We have the medals in our possession and they will be returned," Ueberroth said.

Scherr said Jones would also have to forfeit all her competition results since 1st September, 2000.

"We also will go after prize bonuses and it is in excess of 100,000 dollars," Scherr said. "We will ask her to make restitution for any money she received from the USOC."

Jones was also slapped with a two-year competition ban by the United States Anti-doping Agency (USADA) on Monday but she had already announced her retirement on Friday.

Jones was unavailable for comment.
