Portage police say it’s possible homicide charges won’t be filed against a 54-year-old man who shot his neighbor to death Monday.  Investigators say Victor Reynolds and 49-year-old Calvin Eldridge argued over the loud music Reynolds was playing.  When Eldridge slammed a door and walked away, police say Reynolds followed him and started a fist fight.  That’s when Eldridge pulled out a gun and shot his neighbor.  There was apparently a history of arguments between the two men.  Eldridge currently faces a charge of recklessly endangering safety.  The Columbia County district attorney will determine whether that charge is upgraded.
