Nashville Police have released security footage showing the harrowing moments of The Covenant School shooting. 

In the security footage, shooter Audrey Hale is seen driving a Honda Fit into the school parking lot before exiting the vehicle armed with two assault-style rifles and a 9mm handgun. Hale blasts through the front door of the school and is seen roaming the hallways and slipping into various rooms in search of potential victims. Hale shot and killed three 9-year-old students and three staffers before being fatally shot by police after opening fire on two officers from a second floor window of The Covenant School.
