A doctor in Spain has been convicted of endangering the lives of elite cyclists by administering blood transfusions to increase performance. But the case has left key questions unanswered.
A 2006 raid on Eufemiano Fuentes's office yielded a cache of performance-enhancing drugs and a number of bags containing blood and plasma.
But at that time, Spanish law did not recognize doping as an offense; the doctor was charged on public health grounds.
And now that the case has been concluded, the presiding judge has ordered the bags of blood to be destroyed.
That's causing consternation among anti-doping authorities worldwide: if the blood were to be analyzed, it might reveal more about the breadth and depth of doping in Spanish sports.
