Prosecutors and defenders battled over the defense's request to independently test blood found at the murder scene and at Simpson's estate. But Superior Court Judge Lance Ito said he would hold off on dividing the samples until he heard from experts on whether this would leave the prosecution with enough samples for its testing. Lawyers on both sides of the case were sharply critical of each other as the day wore on, and rightly so, says TIME law writer Andrea Sachs. "It's not surprising that there's a battle going on the DNA testing," says Sachs. "It may turn out to be the center of the case."
