Investigators: Armstrong told Oprah two whoppers

..."You did not do a blood trans­fusion in 2009?" Winfrey asked. "No, 2009 and 2010 absolutely not," Arm­strong said.
Investigators familiar with the case disagree. They said today that Armstrong's blood values at the 2009 race showed clear blood manipula­tion consistent with two transfusions. Armstrong's red blood cell count suddenly went up at these points, even though the number of baby red blood cells did not.
Investigators said this was proof that he received a transfusion of mature red blood cells.
      If Armstrong lied about the 2009 race, it could be to protect himself criminally, investigators said.
     Federal authorities looking to prosecute criminal cases will look back at the "last overt act" in which the crime was committed, they explained. If Armstrong doped in 2005 but not 2009, the statute of limitations may have expired on potential criminal activity.
