Denis Barry successfully prosecuted Gary Winter, a double murderer who has received another life sentence for trying to kill a fellow "lifer" at HMP Woodhill. He repeatedly kicked Lee Newell to the head. A prison officer said they were the worst injuries he had ever seen.
Gary Vinter originally pleaded not guilty to attempted murder but then changed his plea to guilty on Tuesday while on trial at Luton Crown Court.
