A tense standoff unfolded near a popular Grand Junction trail Wednesday morning after a man with a gun refused to surrender and began setting fires. First responders quickly moved in, diffused the danger, and got the suspect into custody without any shots being fired.

Grand Junction’s calm morning jolted by escalating emergency

It was just before 9 a.m. on June 11 when the calls started coming in. A man with a firearm was reported wandering near the Riverfront Trail by 25 Road — an area that’s usually quiet, a spot where joggers, dog-walkers, and cyclists start their day.

The man, later identified as 65-year-old Celestino Marquez, wasn’t just armed. He told police he had both a gun and a knife and wasn’t afraid to use them.

What followed was an hour-long ordeal involving police, firefighters, drones, and open flames. Somehow, nobody was hurt. But it could’ve ended very differently.

Officers corner man who threatened to shoot, then starts fires

When Grand Junction police showed up, things escalated fast. Officers tried to speak with Marquez, but according to police, he flat-out refused to cooperate. Instead, he made it clear: he was armed and willing to shoot.

Then, in a move that stunned onlookers and responders alike, Marquez started lighting fires.

One small spark and a dry Colorado morning — it could’ve spiraled out of control. But GJPD didn’t act alone. The Grand Junction Fire Department was already nearby and jumped into action.

Tech and teamwork: how responders got it under control

The partnership between police and fire crews proved crucial. With smoke rising and the suspect unstable, communication and coordination had to be spot on.

Dirk Clingman, Community Outreach Specialist for GJFD, later explained how both departments teamed up seamlessly, as they often do.

“We respond to calls daily together,” Clingman said. “If it’s a medical call or a rescue or in this case a fire, our crews can respond to provide support and resolve these situations together.”

What made the difference this time? Technology — and quick thinking.

Drones, river pumps, and split-second decisions

Both departments deployed drones to scan the area, get visuals of the fire, and track Marquez’s movements. GJFD used pumps to pull water straight from the Colorado River. Time was tight. Conditions weren’t forgiving.

Clingman emphasized the value of staying updated with tools that could protect both lives and property.

“It’s imperative we keep up with technology because it is very, very helpful,” he said. “Not only do we have a drone, but PD was utilizing a drone today to locate all those areas and provide support to our personnel.”

Firefighters on the ground needed those aerial views to plan their approach and avoid walking straight into danger.

One sentence sums it all up: Nobody got hurt.

Charges filed: a long list for Marquez

After the situation was brought under control and the fires were put out, police were able to arrest Marquez. He was taken into custody and booked at the Mesa County Detention Facility.

Authorities say no shots were fired. And that matters — especially when officers face armed suspects who threaten violence.

But the charges Marquez now faces are serious. They include:

• First Degree Assault

• Multiple counts of Arson

• Additional charges related to outstanding warrants

His past history hasn’t been released yet. But this incident alone could mean significant prison time if convicted.

What we know — and what’s still unclear

Several key details have been confirmed, but a few questions remain unanswered.

For now, here’s what’s clear:

What hasn’t been publicly released is why Marquez was in the area or what prompted his behavior. Police haven’t mentioned whether drugs, alcohol, or mental health played a role.

It’s also unclear how many fires he started or how much land was affected.

Fire threat neutralized — but danger was real

GJFD confirmed the fires were extinguished before they could spread far. Thanks to early detection and rapid response, the flames didn’t get a chance to jump to nearby brush or structures.

“It isn’t a problem going forward,” the department said in a brief update.

That’s a relief. Wildfires aren’t a joke in western Colorado — especially as summer sets in. One careless match in the wrong place, and you’re suddenly fighting something far worse than smoke.

Community reaction: relief, but nerves still rattled

People living nearby say they were rattled. Some were just heading out for a walk or dropping off kids at summer programs when sirens broke the calm.

One resident said, “You don’t expect to see police cars and fire trucks racing past your house and then hear someone set a fire. It’s terrifying.”

There’s also frustration. Why did this happen? Could it have been prevented? Not everyone is satisfied with how mental health and safety are addressed in the area.

But others praised the response.

“They were there so fast. Like, right away. And they kept it from getting worse,” said a man who bikes the trail every morning. “It could’ve gone bad, but they kept their cool.”
