A high school senior was killed and another injured when accidental gunfire erupted inside an Alabama high school on Wednesday. Courtlin Arrington, a 17-year-old senior at Birmingham’s Huffman High School, was pronounced dead following the incident. Another 17-year-old teen was also shot, but he is said to be in stable condition, the New York Daily News reports. His name has not been released. Police have yet to release the name of the shooter, nor the reason why the shooting happened. “At this particular time, we consider it accidental until the investigation takes us elsewhere,” said Birmingham Police Chief Orlando Wilson. ”We have a lot of unanswered questions. There are so many unknowns at this time.“ Wilson also noted that this school shooting was unlike those that have taken place nationwide. ”It’s not where someone from outside came into the school,” he added. Arrington had already been accepted into college with plans to graduate from her high school this upcoming May, according to AL.com. She wanted to become a nurse. “We’re not just talking about some person, we’re talking about losing a part of our future,” said Birmingham Mayor Randall Woodfin. ”Our hearts are heavy.“
