He allegedly exchanged gunfire with a 24-year-old man who was hospitalized with non-life threatening wounds.
Ernest Bernard Felton was arrested Sunday, hours after the shooting at an off-campus apartment complex closer to LSU than SU.
The two Southern University students slain during a shootout at an off-campus party appeared to be "innocent bystanders" who were caught in the crossfire, authorities said Monday. Investigators have identified the victims as Lashuntae Benton and Annette January, both 19. The 24-year-old victim returned fire from his vehicle. Felton was later arrested and charged with attempted second-degree murder and illegal use of a weapon.
Baton Rouge Police say that the shooting happened while people were gathered outside of a social function in the 700 block of Ben Hur Avenue at about 2 a.m.
WBRZ-TV in Baton Rouge is reporting that two women have been shot and killed and another person has been injured in an early morning shooting at the Cottages apartment complex near the LSU campus.
A mother of one of the slain students said police told her that her daughter, 19-year-old Lashuntae Benton, of Lake Charles, wasn't an intended target of the shooting.
Officials investigate the scene where two female Southern University students were killed at The Cottages Apartment Complex in Baton Rouge, La., Sunday, April 10, 2016.
Benton died at the scene, and January died shortly after at a local hospital. January was a freshman and member of the track and field team. "Everybody she talked to just loved her and I'm going to miss her. I just wish it was a nightmare", said cousin Brittany Moss.
"Annette was an ideal role model student, a sweetheart", he said. "Everywhere she won, came out a victor, came out on top", she said.
"My baby was a very vibrant child, an attractive child with a lovely heart", Tillman said during a telephone interview.
Protho-Guider said she and track team at Bowman had last seen January over the Christmas break when she trained with the team daily.
"Annette wanted to be the best at whatever she did", Protho-Guider said. "The University asks for prayers and support for the families at this hard time".
Benton's mother, Theresa Tillman, told the Associated Press that her daughter was studying sports medicine at Southern.
