John Mark Karr Reinstated to Tour

PARIS, France (AP) -- Tour Officials abandoned their case against schoolteacher John Mark Karr on Thursday, saying that both A and B test samples were negative, failing to prove Karr was guilty of doping.

The World Anti-Doping Agency vice president Jean-Francois Lamour suggested how the case against Karr was built -- and unraveled -- in a five-page motion asking tour officials to reinstate Karr.

Lamour said "no evidence has developed, other than Karr's own repeated admissions, to suggest that he is using banned substances in this year's tour."

Karr, who claims that Alexandre Vinokourov personally injected him in the buttocks on numerous occasions, was distressed at the motion and said that he would file an appeal.
