The Columbia County Sheriff’s Office is hoping somebody knows something about a September homicide.  Investigators are trying to kind the person who killed 35-year-old Keith R. Wolf when he went to investigate a noise in the basement of his family home.  Wolf’s wife says he was looking for an intruder while she called 9-1-1.  When deputies arrived, they found her and a small child unharmed, hiding in another room.  Authorities are looking for an S-U-V or truck with a loud exhaust which was on Bradley Road, September 27th, between 9:00 and 10:00 P-M
