When asked by the judge if he would like to explain his actions on the day of the murder, he said, “No, sir.”Johnston said the evidence would have proven Dixson’s blood and Williams’ DNA were both in the cab and that Dixson’s blood was on the jeans Williams wore the day of the killing.Williams left the courtroom in the custody of Lamar sheriff Brad White and other deputies. His feet were chained.
