A 114 MPH Traffic Stop Turns Into a Violent Roadside Struggle on Arkansas I-49

The first several minutes of the video look like countless other highway enforcement encounters.

Traffic moves along Interstate 49.

An Arkansas State Police cruiser travels with the evening flow.

Then a gray Toyota C-HR passes.

What follows begins as a speeding investigation but ends with a state trooper on the pavement, a passing motorist abandoning her own journey to intervene, a Taser thrown into interstate traffic, and one gunshot bringing an exhausting roadside struggle to an abrupt halt.

The driver was 26-year-old Angel Zapet-Alvarado.

The trooper was Alexandria Duncan.

Arkansas State Police said Zapet-Alvarado passed Duncan's marked patrol vehicle at 114 mph in heavy traffic on southbound I-49 near mile marker 83 on July 27, 2024. Duncan activated her emergency lights and siren, but the Toyota did not immediately stop.

Eventually, it pulled onto the shoulder.

What happened there became far more complicated than the initial police account alone suggested.

The encounter included a serious language barrier, rapid escalation, repeated Taser deployments, physical resistance and ultimately deadly force. A Benton County prosecutor later concluded Duncan's shooting was legally justified, while Zapet-Alvarado's attorney publicly questioned the way the trooper initiated and escalated the roadside contact.

The result is footage worth examining carefully rather than reducing to a simple hero-versus-villain narrative.

A Toyota Flies Past the Trooper

The encounter began at approximately 7:43 p.m.

According to the official Arkansas State Police investigative summary, Duncan was working southbound Interstate 49 when she attempted to stop Zapet-Alvarado for speeding and reckless driving.

ASP said the Toyota was traveling at 114 mph.

Duncan activated her lights and siren.

The Toyota continued for approximately another mile before finally stopping.

That delay immediately increases uncertainty for an officer.

A driver may simply be searching for a safer shoulder.

He may not have noticed the emergency lights.

He may be confused.

Or he may be preparing to flee.

The officer approaching the vehicle does not yet know which explanation applies.

Eventually, Zapet-Alvarado pulls onto the right shoulder.

Duncan stops behind him.

Traffic continues moving only feet away.

Then she approaches the driver's side.

The Encounter Escalates Almost Immediately

There is little of the conventional rhythm associated with an ordinary traffic stop.

Duncan approaches and opens the driver's door.

According to her later statement to investigators, she believed Zapet-Alvarado was trying to place the Toyota into drive. She said she put the vehicle back into park and removed the keys because she feared being dragged if he attempted to leave.

She orders him out.

He does not exit.

Duncan begins trying to physically remove him.

The situation rapidly becomes a struggle.

This is also where later criticism of the stop focused.

Zapet-Alvarado's attorney, Aaron Cash, argued that Duncan's immediate physical approach escalated the situation and questioned why she did not begin with the more conventional process of requesting license, registration and insurance or waiting for backup.

That criticism became particularly relevant because another issue was becoming increasingly obvious:

Zapet-Alvarado appeared to have difficulty understanding Duncan's English commands.

A Language Barrier Complicates Everything

The dashcam records repeated commands.

But communication requires more than one person speaking.

Zapet-Alvarado was Guatemalan, and subsequent reporting described him as having limited English proficiency.

An interview conducted after the incident required translation between Spanish and English.

During the roadside struggle, he can repeatedly be heard questioning what is happening.

That does not automatically excuse physical resistance.

Nor does it mean Duncan could safely assume that noncompliance was simply misunderstanding.

But it introduces an important distinction.

There can be a significant difference between refusing to understand and being unable to understand.

For an officer making decisions in seconds, determining which is occurring can be extremely difficult.

For investigators reviewing footage later, however, the language issue becomes impossible to ignore.

And the encounter continues escalating.

Duncan Deploys Her Taser

Duncan uses her Taser in an attempt to gain control.

It does not end the struggle.

The official investigation says Zapet-Alvarado continued resisting Duncan's attempts to remove and restrain him.

The confrontation spills out beside the Toyota.

Now the location itself becomes another danger.

This is not a parking lot.

It is the shoulder of Interstate 49.

Vehicles are passing at highway speed.

Duncan and Zapet-Alvarado are struggling within feet of active lanes.

Anything dropped onto the roadway can be struck.

Either person could potentially move into traffic.

A passing driver could become involved.

And that is exactly what happens next.

Zapet-Alvarado Gets the Taser

At some point during the struggle, Zapet-Alvarado manages to wrestle Duncan's Taser away from her.

According to the ASP investigation, he throws it into the traffic lanes.

The device bounces off a passing vehicle.

That moment significantly changes the tactical situation.

An officer has now lost control of one of her weapons.

She is still engaged physically with a man who has demonstrated that he can overpower her grip.

And backup has not yet taken control of the scene.

Then someone completely unexpected enters the encounter.

A Passing Motorist Stops to Help

Her name was Kylie Sutton.

She was not a police officer.

She had not been dispatched.

She had no obligation to become involved in a violent roadside struggle.

Sutton later told investigators that she was traveling southbound when she saw what appeared to be two feet sticking out between the police vehicle and the gray Toyota.

She stopped.

Most motorists would understandably keep driving.

Intervening in a physical struggle involving a police officer is dangerous even when the situation appears clear.

Sutton nevertheless approached.

She retrieved Duncan's Taser from the roadway and attempted to return it.

Then she became physically involved in helping Duncan.

Suddenly, the traffic stop involved three people fighting for control on the shoulder of an interstate.

The Struggle Lasts Much Longer Than It Feels

Watching police footage can distort time.

Thirty seconds of physical confrontation can feel long.

A minute can feel exhausting.

According to the official ASP investigative timeline, Duncan struggled with Zapet-Alvarado for approximately four minutes and 26 seconds from the initial noncompliance until the shot was fired.

Four and a half minutes of continuous physical resistance is significant.

Strength decreases.

Breathing changes.

Fine motor control deteriorates.

Decision-making becomes harder.

The participants are also on uneven ground beside highway traffic.

Duncan is attempting to control Zapet-Alvarado.

Zapet-Alvarado is attempting to resist.

Sutton is trying to help.

And nobody yet has complete control.

Then the balance shifts again.

Duncan Goes to the Ground

ASP investigators said Zapet-Alvarado managed to get on top of Duncan.

The official investigation states that he kicked Duncan twice in the head during the confrontation.

Head strikes are particularly serious.

A person does not need to lose consciousness for a head injury to compromise their ability to defend themselves.

For a police officer carrying a firearm, losing consciousness during a physical struggle creates an additional risk: the weapon itself may become accessible.

Sutton again intervenes.

According to investigators, she attempted to get onto Zapet-Alvarado's back.

That assistance gave Duncan an opportunity to regain leverage.

Duncan pulled Zapet-Alvarado toward the ground.

But the struggle did not end.

The Moment Deadly Force Enters the Encounter

Duncan eventually draws her service weapon.

This is the decisive moment.

A Taser is designed as a less-lethal tool.

A handgun represents deadly force.

The transition between those tools reflects a dramatic change in the officer's assessment of the threat.

Duncan tells Sutton to move away.

Then she fires one round.

The bullet strikes Zapet-Alvarado in the right temple area.

He survives.

The shot finally changes the physical dynamic enough for Duncan to maintain control until additional troopers arrive.

From the time Duncan first approached the Toyota until Zapet-Alvarado was eventually handcuffed with assistance from another trooper, ASP calculated approximately six minutes and 30 seconds.

From the initial attempted traffic stop until the handcuffing, roughly nine minutes had passed.

Nine minutes transformed a speeding stop into an officer-involved shooting.

Both Duncan and Zapet-Alvarado Need Medical Attention

The gunshot was not fatal.

Zapet-Alvarado was transported to Mercy Hospital in Rogers for treatment.

Duncan also suffered non-life-threatening injuries and received medical care.

Investigators then began reconstructing the encounter.

This process was separate from the immediate arrest investigation.

Because an Arkansas State Police trooper had fired her weapon, the agency's Criminal Investigation Division conducted an officer-involved-shooting investigation.

The case file was eventually submitted to Benton County Prosecutor Joshua Robinson.

He had to determine whether Duncan's use of deadly force violated Arkansas law.

His conclusion was that it did not.

Prosecutor Finds the Shooting Legally Justified

On September 18, 2024, Arkansas State Police publicly released the dashcam footage.

The same day, authorities announced that Robinson had determined Duncan's use of deadly force was consistent with Arkansas law.

No criminal charges would be filed against her for the shooting.

That legal conclusion is important, but it does not mean every tactical decision leading up to the shooting became immune from criticism.

Those are different questions.

A prosecutor can determine that an officer was legally justified in using deadly force at the precise moment a shot was fired while observers can still debate whether earlier decisions unnecessarily increased the likelihood that the encounter would reach that point.

That distinction became central once the video was released.

The Video Creates Questions About the Beginning of the Stop

The official ASP narrative emphasized Zapet-Alvarado's speeding, resistance, seizure of the Taser and assault on Duncan.

Those events are documented in the investigative summary.

But the video also prompted scrutiny of Duncan's tactics.

Arkansas Times reported that Zapet-Alvarado's attorney argued the trooper went outside what he considered the normal sequence of a traffic stop by immediately opening the driver's door and initiating physical contact instead of first requesting documents, calling for backup or using translation assistance.

That does not establish misconduct.

It does show why video matters.

Written reports summarize.

Video allows viewers to examine timing.

How quickly does an officer approach?

When is the door opened?

How much time passes between commands?

What is the driver's apparent reaction?

Those details can shape public understanding in ways a short press release cannot.

Zapet-Alvarado Gives Investigators His Version

Investigators interviewed Zapet-Alvarado at the hospital.

According to the ASP investigative summary, he said he had worked that day, finishing around 4 p.m., rested in his vehicle for about an hour and consumed one light beer.

He said he noticed the blue lights and pulled over.

He also said he did not understand Duncan's instructions.

Most significantly, the investigative summary says Zapet-Alvarado told investigators that after being tased repeatedly he perceived what was happening as an attack and decided to fight the officer rather than comply.

That statement does not erase the physical acts captured on video.

It does, however, provide insight into how differently the two people apparently understood the same encounter.

Duncan believed she was dealing with a driver attempting to evade and resist lawful detention.

Zapet-Alvarado said he did not understand the commands and came to view the physical encounter as an attack.

Those two perceptions collided on the side of I-49.

Toxicology Adds Another Piece

Authorities later reported that Zapet-Alvarado's blood-alcohol concentration was 0.16, approximately twice the standard legal limit for driving in Arkansas.

Investigators also reported cannabinoids in his system.

Alcohol can affect judgment, reaction time, perception and decision-making.

That information provided additional context for the alleged 114 mph driving and subsequent behavior.

But again, context is not the same as a complete explanation.

Several factors were operating simultaneously.

Speed.

Alcohol.

A language barrier.

An aggressive physical struggle.

A highway shoulder.

A lone trooper initially attempting the arrest.

A civilian intervening.

A Taser changing hands.

Head strikes.

And eventually a firearm.

Reducing the encounter to any single one of those elements misses why it became so dangerous.

Kylie Sutton's Decision May Have Changed the Outcome

The civilian intervention deserves particular attention.

Sutton did not know exactly what had happened before she arrived.

She saw an officer in trouble.

She stopped.

She entered a physical confrontation.

She recovered police equipment from active traffic.

Then she helped Duncan while Zapet-Alvarado was physically overpowering her.

The ASP investigative summary makes Sutton's role clear.

It is impossible to know with certainty what would have happened had she continued driving.

But the danger Duncan faced at that moment was obvious enough that a stranger chose to place herself in the middle of it.

That makes Sutton one of the most important people in the footage even though she was never supposed to be part of the traffic stop at all.

A Highway Shoulder Is One of the Worst Places for a Fight

The environment deserves more attention than it usually receives.

Police officers are regularly struck and killed during roadside contacts.

Vehicles passing at highway speed create constant danger.

During this encounter, the Taser itself was thrown into traffic and reportedly struck a vehicle.

Duncan, Zapet-Alvarado and Sutton repeatedly moved around the narrow shoulder.

The Toyota's driver's door remained open.

Passing motorists continued only a short distance away.

Every additional second of the struggle increased the chance that the incident could expand beyond the people already involved.

This is one reason roadside officers often try to gain control quickly.

It is also one reason tactical decisions during highway stops require careful judgment.

Moving too slowly can leave an unresolved threat beside traffic.

Escalating too rapidly can produce an unnecessary physical confrontation.

There is rarely a perfect option once cooperation breaks down.

The Dashcam Captures What Body-Worn Video Might Not

The perspective in the supplied video is unusually revealing.

The camera remains mounted in the patrol vehicle.

That means it does not move with Duncan.

At first, this seems like a limitation.

Then the struggle moves directly into its field of view.

The fixed perspective allows viewers to see the Toyota, the highway, passing vehicles, Sutton's arrival and the changing positions of the people involved.

A body camera would provide a closer perspective but might become obscured during wrestling.

The dashcam provides distance.

It shows how long the encounter lasts.

It also shows just how exposed everyone is to highway traffic.

This broader perspective is one reason the release generated so much discussion.

The Case Becomes More Complicated After the Video Release

The public conversation did not end when prosecutors cleared Duncan's shooting.

Criticism emerged over how the stop was initiated and how officials characterized Zapet-Alvarado afterward.

Arkansas Times reported that his attorney was considering civil-rights issues and emphasized the apparent language barrier visible in the footage.

Later commentary also reported that felony charges against Zapet-Alvarado were dropped, while the political use of the incident became controversial.

That later development illustrates why early police narratives should not be treated as the final word in a case.

An incident can have multiple stages of review.

Police investigation.

Prosecutorial review of the officer's actions.

Criminal proceedings against the arrested person.

Potential civil litigation.

Administrative review.

Public scrutiny.

Each process asks a different question.

Legal Justification and Tactical Perfection Are Not the Same Thing

This is perhaps the most useful lesson from the entire case.

The Benton County prosecutor concluded Duncan's ultimate use of deadly force was legally justified.

That answers a specific legal question.

It does not necessarily answer:

Could the stop have been handled differently?

Would waiting for backup have changed the encounter?

Could translation assistance have reduced confusion?

Was opening the door immediately necessary?

Would another tactical approach have produced the same outcome?

Those questions are inherently harder because they require imagining alternatives.

The video cannot show what would have happened in a different timeline.

What it can show is what actually happened.

A speeding vehicle stopped.

The trooper approached.

Communication failed.

Physical control failed.

A Taser failed to end the resistance.

The Taser changed hands.

A civilian became involved.

The trooper was kicked.

And deadly force was ultimately used.

Four Minutes Can Completely Change an Encounter

The most striking element is not the single gunshot.

It is everything required to reach it.

The confrontation does not immediately jump from a speeding ticket to a shooting.

There is a prolonged physical struggle in between.

Four minutes and 26 seconds.

That is long enough for exhaustion to fundamentally change the people involved.

Long enough for a weapon to change hands.

Long enough for a passing motorist to recognize the danger, stop her car and enter the confrontation.

Long enough for an officer's original plan to collapse completely.

By the time Duncan fires, the traffic stop that began minutes earlier effectively no longer exists.

This is now a fight for physical control on the shoulder of an interstate.

The Most Important Question Is Not Who “Won”

Police videos often attract simplistic reactions.

One side praises the officer.

Another blames the officer.

One side condemns the driver.

Another focuses entirely on the driver's treatment.

This case does not fit comfortably into a one-line interpretation.

Zapet-Alvarado was accused of traveling at an extraordinary speed and physically resisting Duncan.

The investigation found he took the trooper's Taser and kicked her in the head.

At the same time, the footage raised legitimate questions about communication, tactics and the rapid escalation at the driver's door. His attorney publicly challenged those decisions.

Both facts can exist simultaneously.

Acknowledging one does not require pretending the other never happened.

That is what makes the footage valuable.

It forces viewers to confront the entire sequence.

One Stranger Changes the Story

Without Sutton, the video would be a story about a trooper and a driver.

With her, it becomes something different.

A civilian sees trouble from the highway.

She stops.

She gets out.

She retrieves a Taser from traffic.

She physically helps a trooper she has never met.

There is no time for Sutton to study police policy.

No time to read an investigative report.

No time to know what happened before she arrived.

She makes a decision based on what she sees.

Someone appears to need help.

She helps.

The official investigative record confirms that her intervention assisted Duncan during the struggle.

That moment is one of the most human parts of the entire video.

The Gunshot Ends the Fight, Not the Questions

Eventually additional troopers arrive.

Zapet-Alvarado is handcuffed.

The roadway returns to something resembling normal.

Cars continue passing.

The Toyota remains on the shoulder.

Medical treatment begins.

Investigators take over.

The physical confrontation is finished.

The questions are not.

Why did Zapet-Alvarado continue at 114 mph?

Why did he resist?

How much did alcohol affect his decisions?

How significant was the language barrier?

Could Duncan have handled the opening seconds differently?

At what precise moment did deadly force become legally justified?

What role did Sutton's intervention play?

Those questions continued long after everyone left the interstate.

What the Video Ultimately Shows

There is a temptation to use the footage as proof of whatever conclusion a viewer already holds about policing.

That would waste what makes the video informative.

It shows how quickly uncertainty compounds.

Duncan does not know exactly why the Toyota initially fails to stop.

Zapet-Alvarado apparently does not fully understand what Duncan is telling him.

Duncan interprets movement toward the gear selector as an attempt to leave.

Physical force begins.

Zapet-Alvarado interprets the repeated Taser use as an attack, according to his later interview.

He fights.

The trooper loses control of the Taser.

A stranger intervenes.

The officer ends up beneath the person she was trying to arrest.

Then a firearm enters the encounter.

Each decision changes what becomes possible next.

By the end, there is no longer any resemblance to the original speeding stop.

There is only a wounded man, an injured trooper, a civilian who unexpectedly became part of an arrest, and investigators tasked with reconstructing how everything escalated so far.

The prosecutor ultimately decided the final use of deadly force was lawful.

The video nevertheless leaves viewers with a broader lesson.

A traffic stop does not become dangerous because of one dramatic moment.

It becomes dangerous through a chain of moments.

Sometimes that chain takes seconds.

Here, it took several exhausting minutes.

And on the shoulder of Interstate 49, those minutes were enough to turn a 114 mph speeding violation into one of the most debated Arkansas State Police traffic-stop videos of 2024
