A conversation between a man and a woman and another man and a woman turned into an argument which ended with shots fired into the floor in the 500 block of Union St. in Valparaiso, shortly after midnight Wednesday.  According to published reports, ricochet fragments from the bullet hit the other man causing superficial injuries.  People who were there said after the shooting the man only known by the name of “Gifted” and the woman he was with walked away. The case remains under investigation. Anyone with information should contact the Valparaiso Police department.
