A 17-year-old boy was also shot and survived in the Wednesday afternoon incident during dismissal at Huffman High School in Birmingham, police said. Police have not identified the student but issued this statement Thursday morning: "Detectives of the Birmingham Police Department have been working through the night reviewing evidence, video and statements on the tragic incident that took place at Huffman High School yesterday.  A person of interest has been taken into custody after a 17-year-old girl was shot dead at an Alabama high school Wednesday, police said. Charges are pending a review of the case by the Jefferson County District Attorney’s office, the Birmingham Police Department said today. Because the charges are pending we will not be releasing any information on the individual in custody. Further information will be released as it becomes available." Initially Birmingham police officials said the deadly shooting, which happened inside a classroom as school was dismissing for the day, appeared to be accidental. We learned Thursday that the shooting was captured on video and led authorities to pursue the charges against the student. We have the gun, we have the one who had the gun. The shooting happened at 3:45 p.m. Arrington was given CPR at the scene and en route to UAB Hospital but was pronounced dead upon arrival at 4:16 p.m.. He was treated in the emergency room and quickly released into police custody where he was questioned and held overnight in the Birmingham City Jail. Kay Ivey said on Twitter Wednesday, "I'm praying for the family of this young lady who tragically lost her life way too early." On Thursday, Herring met with Acting Police Chief Orlando Wilson and his staff to come up with a safety plan for heightened security when students return to school on Friday. Many have questioned the use of metal detectors at the school, and whether they were in use Wednesday. Dr. Lisa Herring, Superintendent of Birmingham City Schools, said Huffman High School does have working metal detectors in use but declined to comment further as it is part of the ongoing investigation. "Our entire Birmingham community is in mourning and grief right now. While there are many questions ...we need to take to the time realize that a life was lost. "
