14 minutes: Visual timeline of Nashville school shooting from break-in to police response
Nashville, Tennessee, remains in mourning and details continue to emerge in the Covenant School mass killing Monday, in which three teachers and three 9-year-old students died. The shooter was killed by police.
Nashville police on Tuesday released six minutes of body cam footage from officers confronting the shooter and about two minutes of video from security cameras that show the shooter walking in school hallways.
About 14 minutes elapsed between the first 911 call about an active shooter at the school and police confirming the shooter's death after an exchange of gunfire on the second floor.
Police identified the shooter as Audrey Elizabeth Hale, 28, a former school student, and said Hale identified as transgender. A motive remains unknown.
