DNA testing that showed traces of Roger Clemens' cells on a collection of steroid-laced medical waste was reviewed in court on Friday in the former pitcher's perjury trial in Washington, D.C. Included in the tested items was a needle used for injections that likely contained Clemens' genetic material. Government witness Alan Keel, a veteran DNA analyst from a private lab in California who performed the tests, took the stand on Friday, the New York Daily News reported. Keel spent the day on the witness stand describing his forensic examination of a needle, tissues, blood-stained gauze and cotton balls that McNamee said he saved in 2001. Keel said he found DNA of Clemens and McNamee on the items. \"I would expect to find this profile unique to only one person that has ever lived on the planet,\" Keel said. The items were turned over to the federal government by Clemens' former trainer Brian McNamee in 2008. Keel said there was only a 1 in 173 trillion chance that cotton balls apparently stained with Clemens' blood could possibly belong to another randomly selected Caucasian American. Keel said a needle he tested was comparable to one Clemens submitted to federal agents in 2008. According to Keel, the chances the needle had of being a different match from Clemens was just 1 in 449. Because the sample contained only six to 12 cells, Keel said there is almost no way it could be faked, countering what Clemens' lawyers have been arguing. \"In my opinion, it would be virtually impossible for someone to have left only the trace amount of material by design,\" Keel said. The medical waste came from a Miller Lite beer can that McNamee used to store as evidence in 2001.<\/p>\n<\/p>\n
