(Williamson County, IL) — A Herrin man who is behind bars for killing his son wants a new sentence. Brandon Vaughn returned to court Monday requesting a judge to reconsider his twelve year sentence for involuntary manslaughter. He pleaded guilty to that charge in exchange for prosecutors dropping murder charges. Police investigators say Vaughn smothered his three-month-old son by throwing a comforter over his face. The State’s Attorney’s office says Monday’s hearing was continued so that Vaughn’s lawyer could have more time to gather much needed court documents.
