The Rock County Sheriff’s Office reports a two-hour standoff with an armed man was ended peacefully after a robot was sent inside.  Deputies were called to the Afton home Saturday for a shots-fired incident with the suspect in the home with his adult son.  Deputies made contact with the son after he had removed the rifle, but they decided to wait when he told them there were additional weapons in the house.  A SWAT team deployed the robot and the elderly man was found in a bedroom.  He was taken to a hospital for treatment of injuries he suffered while handling the rifle.  Authorities say they are still investigating, but they don’t think criminal charges will be filed.
