Dramatic bodycam footage released by police shows the moment hero officers confront evil Nashville mass killer Audrey Hale.
Metro Nashville Police Department (MNPD) officers Rex Englebert, 27, and Michael Collazo arrived at Covenant School on Monday and heroically raced through the corridors before locating and shooting dead the former student, who used two assault rifles and a pistol to kill six victims.
During the hellish six-minute clip, a member of distressed staff comes out and tells officers that "we're on lockdown" before instructing them inside.
The new video from Officer Engelbert's bodycam shows a woman greeting police outside as they arrive at The Covenant School on Monday. "The kids are all locked down, but we have two kids that we don't know where they are," she tells police.
"OK, yes, ma'am," Engelbert replies.
The woman then directs officers to Fellowship Hall and says people inside had just heard gunshots. "Upstairs are a bunch of kids," she says.
Cops then enter the school hallway shouting "Metro Police" and burst into the classrooms - with no sign of the killer.
Sirens, shouting and gunshots can be heard in the footage as cops storm around the school looking for the shooter.
Police are seen running downstairs and firing shots before eventually finding Hale - and shoot dead the killer.
The courageous officers go classroom by classroom before they find the shooter on a second floor atrium.
Three officers, including Engelbert, search rooms one by one, holding rifles. "Metro Police," officers yell.
"Let's go, let's go," one officer yells.
As alarms are heard going off in the school, one officer says, "It sounds like it's upstairs."
Officers climb stairs to the second floor and enter a lobby area. "Move in," an officer yells. Then a barrage of gunfire is heard.
Hale fires in their direction but was no match for Officer Englebert, who has been with the fource for four years and gunned down hale with four shorts from his semi-automatic rifle.
Officer Collazo, who has been with the force for nine-years, then approaches Hale's prone body with a handgun next and fires another four shots while the killer flails on the ground.
"Get your hands away from the gun," an officer yells twice. Then the shooter is shown motionless on the floor.
The officers then approach the body and strip it of weapons.
The force said Engelbert and Collazo were “part of a team of officers who responded to the Covenant Church/School campus Monday morning and immediately entered the building.”
Five cops in total came upon the shooter, police spokesperson Don Aaron told reporters.
The footage comes after video released by police showed Hale shooting their way through a side door of the school where the killer was eventually killed on the first floor of the building by cops.
The dramatic, six-minute video supplements the earlier release, late Monday, of about two minutes of edited surveillance footage that shows the shooter's car driving up to the school, glass doors being shot out and the shooter ducking through one of them.
It was revealed cops had searched the killer's house and found a detailed map of the school, including potential entry points, and evidence clearly done surveillance before the shooting.
Cops also described Hale as a "lone zealot", who had written a manifesto ahead of the attack.
Evelyn Dieckhaus, Hallie Scruggs and William Kinney, all nine-years-old, were shot dead by the former student.
Cynthia Peak, 61, a substitute teacher, Mike Hill, 61, a janitor, and Katherine Koonce, 60, who was the head of the school, were all also killed in the horrific shooting.
Victim Evelyn Dieckhaus, 9, was one of three child victims killed by Hale.
She was a third grader at the school and went in each day with her sister, a fifth grader.
At the end of a vigil at Woodmont Christian Church, Evelyn’s sister broke down in tears as she said: “I don’t want to be an only child.”
Victim Katherine Koonce, 60, was the head teacher at The Covenant School in Nashville.
One parent described her to the BBC as a "saint".
The mum said: "She did so much for those kids. And now gave her life protecting them."
She added: "She knew every single student by name.
"She did everything to help them when families couldn't afford things, it didn't matter. She found ways for them to stay."
Mike Hill, a custodian at the school, was also one of the adults to be killed.
Tim Dunavant, a pastor who had previously worked at Covenant, had hired Mr Hill over 13 years ago.
He said he would not be surprised if Mr Hill had sacrificed his life to save children because "he's the kind of guy that would do that".
The third adult killed was Cynthia Peak, 61, who police say was a substitute teacher.
She was raised in Leesville, Louisiana and is survived by her husband, a daughter and two sons.
Senior pastor Nathan Parker said: "It has been a hard day. We are sad.
"Sad for the families who came rushing to our church. Sad for those whose lives will never be the same because of the trauma inflicted on them. Sad because we live in a world broken by sin, suffering, and death."
