PULSE-pounding police body camera footage shows the moment officers storm into The Covenant School and take down mass shooter Audrey Hale. The video reveals the swift efforts of Metro Nashville police officers Rex Engelbert and Michael Collazo in stopping Hale's reign of terror during Monday's school shooting. Engelbert walks into a hallway area on the second floor, where he encounters Hale firing shots out the window. A second footage from officer Collazo's body camera shows how he also fired five shots from his handgun after Hale continued to move. The shooter is shown motionless on the floor as Collazo communicates through the radio, "Suspect down, suspect down."
