Blood samples found at the murder scene and at O.J. Simpson's estate will be parceled out so that both the prosecution and defense can conduct their own DNA and other tests. Judge Lance Ito ordered 10 percent of the samples to go to the defense and 90 percent to the prosecution. The decision was supposed to put to rest a contentious issue that has been a focus of Simpson's trial so far, since blood may be the key evidence that links O.J. to the murders. But the defense is loudly objecting to the way the blood will be divided: at the hands of the prosecution's experts.
