DNA on needle likely belongs to Clemens

WASHINGTON — A needle stored with a beer can appeared to contain an extremely tiny amount of Roger Clemens’ DNA, which turned out to be good news and bad news for both sides in the perjury trial of the seven-time Cy Young Award winner.

A forensic scientist on Friday linked Clemens to cotton balls and a syringe needle saved from an alleged steroids injection 11 years ago. His testimony, laced with statistics and probabilities, was one of the last pieces of the government’s case in its effort to prove that the pitcher lied to Congress in 2008 when he denied using performance-enhancing substances.

Under cross-examination, Clemens’ lawyer tried to poke holes in the physical evidence. He got the expert to acknowledge there were “hundreds of thousands” of white males in the United States who could be a match for the scant amount of DNA found on the needle, and that it’s “conceivable” the cotton balls could have been contaminated by beer and saliva.

The government’s key witness, longtime Clemens strength coach Brian McNamee, says he injected Clemens with steroids in 1998, 2000 and 2001 and with human growth hormone in 2000. He said he kept the needle and other waste from a 2001 injection and stored it in and around a beer can in a FedEx box in his home for more than six years before turning it over to federal investigators.

Alan Keel, of Forensic Science Associates, told jurors that the DNA found on two cotton balls was “unique to one person who has ever lived on the planet”– Clemens.

But the needle was not as conclusive. Keel was able to detect only six to 12 cells for testing when he examined it. A drop of blood, by comparison, contains up to 30,000 cells.

The match: one in 449 for Clemens.
