An argument at a private off-campus party escalated into a shooting outside an Oklahoma State University residence hall early Sunday, wounding three people including a student, school police said.

At least three people were hurt overnight in a shooting on campus at Oklahoma State University, a spokesperson said.

Investigators responded to the 2200 block of North Chadwick Street in North Philly for a report of a shooting. Police said they believe there were at least two shooters involved in the incident and there may have been an argument that led to the shots being fired.

A seventh person has died from injuries sustained in a mass shooting after a high school football homecoming game earlier this month in the Mississippi Delta town of Leland, a coroner said.
