“When Seconds Decide Who Lives: The Cop Who Charged Into Gunfire While Others Once Stood Frozen”
On March 27, 2023, the sound that shattered a quiet Nashville morning was not just gunfire—it was a test.
A test of training.
A test of leadership.
A test of whether law enforcement had learned anything from one of the most painful failures in modern American policing.
Six minutes after the first 911 call reporting an active shooter at The Covenant School in Nashville, Tennessee, Metro Police Officer Rex Engelbert arrived on scene. Within four minutes of entering the building, he and fellow officers located and stopped the attacker.
It was fast.
It was decisive.
And it stood in stark contrast to another school shooting less than a year earlier that unfolded very differently.
This is not a story about the perpetrator. Their name has been deliberately excluded from many retellings, including this one. Investigators later concluded that notoriety was a key motive. Amplifying that name only serves the wrong purpose.
This is a story about response.
The Call That Changes Everything
At approximately 10:13 a.m., Nashville emergency services began receiving reports of gunfire inside The Covenant School, a private Christian elementary school in the city’s Green Hills neighborhood.
The words “active shooter” are among the most urgent phrases in modern policing. Since the Columbine High School massacre in 1999, law enforcement agencies across the United States have fundamentally altered their tactical doctrine. The old method—establishing a perimeter and waiting for specialized units—has largely been replaced with an “immediate entry” model. The first officers on scene are trained to move toward the threat without delay.
Officer Rex Engelbert was nearby when the call came over the radio.
He was not on patrol in that district. He was not familiar with the school’s layout. He had been handling administrative matters and, by his own account, had “no business being where I was.”
But when the call came, none of that mattered.
He activated his lights and sirens and drove toward the sound of chaos.
Six Minutes
According to the Nashville Metro Police Department, officers arrived at the school roughly six minutes after the initial call.
Those minutes matter.
In active shooter incidents, time is measured not in hours but in lives. Studies of past attacks show that most fatalities occur within the first few minutes. Every delay compounds risk.
When Engelbert exited his patrol vehicle, he did not wait for a full tactical team to assemble. He did not stop to put on additional heavy ballistic plates. He grabbed his patrol rifle and moved.
Two school staff members, who had remained on site despite the danger, provided critical information. They told officers that children were locked down but that shots had been fired. One handed Engelbert a key to the entrance.
That key became the difference between hesitation and entry.
He stepped inside.

“Metro Police!”
Body camera footage released by the department shows Engelbert and other officers moving quickly through hallways, clearing rooms as they advanced. Their voices echo through the corridors:
“Metro Police!”
“Open door!”
“On me!”
They did not know the building’s layout. They did not know where the shooter was positioned. They did not know if there was more than one attacker.
They moved anyway.
Smoke hung in the air. The sound of gunfire guided them upward. Engelbert later described following the “stimulus”—the noise of shots—toward the second floor.
Officers used plain language to coordinate, as many had not previously worked together. There was no elaborate tactical choreography. Just urgency and shared purpose.
Within approximately four minutes of entry, officers encountered the attacker on the second floor. Gunfire was exchanged. Engelbert fired multiple rounds.
The threat was neutralized.
A Tragedy, Even So
Despite the rapid response, six people were killed before officers could stop the attack: three nine-year-old children—Evelyn Dieckhaus, Hallie Scruggs, and William Kinney—and three adults, Cynthia Peak, Katherine Koonce, and Mike Hill.
Their deaths are the enduring center of the story.
No response, no matter how swift, can undo what was already done. But law enforcement officials have stated that the officers’ actions likely prevented additional casualties.
Nashville Police Chief John Drake publicly praised the officers, noting the speed of entry and engagement.
“Our police officers have cried and are crying with Nashville and the world,” he said in the aftermath.
The response became a national reference point—not because it erased tragedy, but because it demonstrated what active shooter protocol is designed to look like.

“I Know My Role”
In a press conference days later, Officer Engelbert spoke quietly about the morning that would define his career.
“It was a regular work day for me,” he said. “I was feeling tired. I hadn’t finished my coffee.”
He described turning on his lights and sirens immediately after hearing the call.
“I treat them all the same,” he said, referring to previous false active-shooter calls. “But something told me it was time to really get to this one.”
He acknowledged he did not know the school’s layout. He emphasized the bravery of staff members who stayed to provide direction. He noted that he had not deployed his heavier rifle-rated plates before entering.
“I know my role,” he said simply.
That role, under modern policing doctrine, is clear: locate the threat and stop it as quickly as possible.
The Shadow of Another School
The Covenant School response unfolded less than a year after the shooting at Robb Elementary School in Uvalde, Texas, on May 24, 2022.
In Uvalde, officers arrived quickly—but entry into the classroom where the gunman was located was delayed for more than an hour. Hundreds of officers from multiple agencies eventually gathered outside.
Parents pleaded with police to act.
Video footage from that day showed chaos, confusion, and breakdowns in command structure. Subsequent investigations cited failures in leadership, communication, and adherence to active shooter protocols.
The contrast between Uvalde and Nashville reignited national debate about what police response should look like—and why it sometimes falters.
While each incident is unique, the comparison has become unavoidable in public discourse. Both involved schools. Both involved rapid initial dispatch. Both demanded immediate action.
But the outcomes in terms of response speed differed sharply.
Doctrine vs. Reality
Since Columbine, law enforcement training across the country has emphasized immediate engagement. Officers are taught that waiting for backup can cost lives. The “first officer on scene” model assumes that even a single officer must move toward the gunfire.
Yet doctrine on paper does not always translate cleanly into practice.
Factors such as unclear command, radio confusion, fear of ambush, and miscommunication can paralyze decision-making. Human beings—regardless of badge or training—must still overcome instinctive self-preservation.
In Nashville, the decision was made quickly.
In Engelbert’s own words, “When I did hear stimulus, I couldn’t get to it fast enough.”
That urgency—moving toward danger rather than away from it—is the core principle of modern active shooter response.
The Cost of Delay
Public frustration in the wake of Uvalde was not merely emotional—it was civic.
In many cities across the United States, policing represents one of the largest portions of municipal budgets. In some municipalities, police funding accounts for 30 to 40 percent or more of general fund expenditures.
Citizens who allocate that level of public investment expect a corresponding level of preparedness and decisiveness in moments of crisis.
When response falters, trust erodes.
When response aligns with training, as in Nashville, departments point to it as evidence that reform and doctrine have meaning.
