WASHINGTON (AP) - A forensic scientist has testified that two
cotton balls and a syringe needle allegedly saved after a steroids
injection tested positive for Roger Clemens' DNA - in a key moment
as the government tries to prove the former pitcher used
performance-enhancing drugs.
Alan Keel told jurors Friday that the DNA on both cotton ball
matches were "unique to one person who has ever lived on the
planet" - Clemens. He said that one cotton ball had a random match
possibility of 1 in 15.4 trillion for Clemens' DNA, and the other
had one in 173 trillion.
The needle was not as conclusive, because Keel was only able to
get a handful of cells. That match was one in 449.
Brian McNamee, Clemens' former strength coach, earlier testified
he collected the medical waste after injecting the pitcher with
steroids.
Clemens is accused of lying to Congress when he denied using
performance-enhancing drugs.
