The shooting happened around 12:45 a.m. at a home in the 2400 block of Euclid Avenue.
Chief Winkle said there was a large party at the home when some sort of confrontation occurred, turning into a shooting.
Seven people were shot and taken to the hospital. Three victims suffered life-threatening injuries.
Police have interviewed dozens of people and are working to identify a suspect in the shooting. Police said they believe they have interviewed a person of interest, however no arrests have been made as of 6:00 a.m. Saturday.
Ball State University released an alert online just after 1 a.m. advising students to stay away from the area as Muncie and Ball State police responded to the shooting. About 40 minutes later, the university released another alert saying there was no ongoing threat to campus.
People at the party were college-aged, Chief Winkle said. It is unclear at this time if any of the shooting victims are Ball State students.
This is a developing story. Look for updates as more information is released.
