be positive if the pants Williams wore at the restaurant were among the garments he gave to Martin.

But Hadley believed that Williams had changed his clothes during the two hours or more between the time he left Winter Garden and when he presented himself at the sheriff's station.  Williams swore that he had changed into the green slacks and black cardigan sweater before he left his apartment to meet Tommy Zeigler.  But three different witnesses—the apartment manager Mary Wallace, Kentucky Fried Chicken employee John Grimes, and customer Ed Nolan—all claimed that they saw Williams wearing khaki pants and a brown jacket or sweater when they saw him on Christmas Eve.

For the defense, the GSR test of Williams's green slacks was a potential chance to impeach his testimony.  It was not a minor point. If he had changed clothes, he must have done so, and then lied about it, because he had something to conceal.

At first the state attorney would not release the disputed items. Then Eagan wrote a letter to Sheriff Colman stating that the OCSO "may release" evidence to the defense, and Gene Annan went to the 33rd Street station to pick up the packages.  But sheriff's officers told Annan that the word "may" implied that the release was at their discretion, and they refused to hand over the evidence.
