Atlanta, Georgia (CNN) -- Prosecutor Jack Mallard was waiting for the moment Wayne Williams, on trial in the Atlanta child murders case, would take the witness stand in his own defense. "I knew he figured he could out-talk the prosecutor," Mallard says. "He had tried out-talking everybody else, and I knew I'd be ready." Under cross-examination, Williams blew up at the prosecutor, saying, "You must be a fool," and then telling Mallard, "You want the real Wayne Williams? You got him right here." In his closing statement, Mallard would quote that outburst to the jury in describing Williams as "a Jekyll and Hyde" personality. A day later, the jury convicted Williams on two counts of murder. He was eventually sentenced to two life sentences in prison.
