A 17-year-old student is in custody as a person of interest in Wednesday's fatal shooting at an Alabama high school, AL.com reports. According to ABC News, police are pursuing charges against the teen but aren't releasing any additional information on his or her identity until charges are filed. The person of interest was also one of the two students injured in the incident, which happened during dismissal in a classroom at Huffman High School in Birmingham. The teen reportedly shot themselves in the leg. They were released from the hospital and into police custody.
The 17-year-old killed in the shooting has been identified Courtlin Arrington. She was set to graduate in May, had been accepted to college, and hoped to become a nurse. A third, non-student person was injured in the shooting and treated at the scene, WBRC reports. Police initially called the shooting "accidental," though the cause is still under investigation. Officials decided to pursue charges after watching video of the incident. "At this particular time, we consider it accidental until the investigation takes us elsewhere,'' acting Birmingham police chief Orlando Wilson says. "We have a lot of unanswered questions. There are so many unknowns at this time." (Read more school shooting stories.)
