Preliminary clues about who shot and killed two female Southern University students this month have been issued from a crime lab, a police spokesman said Wednesday, but authorities haven’t said what the evidence reveals or what it means for the ongoing criminal investigation.

The initial ballistics tests on projectiles recovered from the scene where the two 19-year-old students, Annette January and Lashuntae Benton, were gunned down April 10 at The Cottages apartment complex in Baton Rouge have been turned over to the Baton Rouge Police Department, said department spokesman Sgt. Don Coppola.

But Coppola said he could not comment further on the test results or the investigation.

No one has yet been accused of killing the women.

Ernest Felton, 22, remains in custody in East Baton Rouge Parish Prison on counts of attempted second-degree murder and illegal use of a weapon.

He’s accused of shooting another alleged gunman at the scene, 24-year-old Brandon Henderson, who suffered bullet wounds to his leg and torso in the incident, according to a Baton Rouge police report.

Felton, who was arrested hours after the shooting and who’d bonded out on $90,000 bail a couple days later, violated the terms of his bail by going to Dallas and was rearrested, the police said.

He’s now being held without bail.

Felton and Henderson were involved in an “exchange of gunfire,” according to the report.

The ballistics information is expected to help police confirm which of the shooters are responsible for January and Benton’s fatal wounds.

Henderson has not been arrested or accused in the incident.
