Indirect evidence of Lance Armstrong cheating appears to mount

Yet another former member of Armstrong’s U.S. Postal Service cycling team has tested positive for EPO.

Manuel Beltran is the fourth former Armstrong teammate to test positive for doping; the others were Floyd Landis, Tyler Hamilton and Roberto Heras. Landis lost his apparent 2006 Tour de France win over positive tests for synthetic testosterone. The other two, like Beltran, tested positive for EPO.
