Law enforcement agencies in the Madison area are looking for the shooter who killed a 20-year-old Fitchburg man Monday night.  Investigators say it looks like there was a fight at a home involving several men and during that fight at least one shot was fired.  The victim was taken to a hospital where he died.  His name hasn’t been released.  Fitchburg Police say the other men who were there ran away and haven’t been found.  The death is classified as a homicide because police don’t think they’re dealing with a random act of violence.
