Madison Police say they are waiting on a medical examiner’s report as they try to determine exactly what happened when two men were shot to death.  Investigators say it looks like a murder-suicide.  The bodies of the 58-year-old man and his 33-year-old son were found in a bedroom.  The wife and mother reported the shooting early Sunday morning.  A semi-automatic handgun which had fired four shots was recovered from the scene.  The men’s names haven’t been released.  The case is Madison’s first homicide of 2018.
