A 19-year-old man has been shot dead and three female students wounded in a shooting incident at Tennessee State University in Nashville, police say.
The man was killed in the argument while the wounded persons were passing by.
The latest incident comes a week after three people were wounded by gunfire at an off-campus party near the college.
The suspect fled the scene on foot.
A university spokeswoman said the two men involved in the argument were not students and were believed to have been gambling.
