The sheriff’s office has wrapped up its internal review into a traffic stop that led to a young woman’s detention by federal immigration agents. The fallout? A public apology, disciplinary action, and more questions than answers.

Sheriff Takes Responsibility, But Questions Remain

Sheriff Todd Rowell didn’t mince words. “I take full responsibility,” he said in a written statement released July 30, ending weeks of speculation over a June traffic stop that snowballed into a federal detention.

It started with a routine pull-over. Nineteen-year-old Caroline Dias-Goncalves was driving just a bit too close to a semi-truck near Fruita on June 5. Deputy Alexander Zwinck initiated the stop. But what happened next wasn’t routine — not by a long shot.

Without a warrant, Zwinck took a photo of what he believed was Goncalves’ driver’s license. He then sent it to a private group chat made up of local and federal law enforcement officers. Days later, Goncalves was in ICE custody.

Encrypted Chats and Unofficial Channels

Deputy Zwinck didn’t radio it in. He didn’t file a report through official systems first. Instead, he shared Goncalves’ ID photo in a private Signal chat, an app known for end-to-end encryption and secrecy.

This group chat wasn’t small. It included members of:

• Mesa County Sheriff’s Office

• Colorado State Patrol

• Homeland Security Investigations

• Drug Interdiction Teams from across Colorado

Zwinck claimed ICE wasn’t directly in the chat. But Homeland Security was. And that’s where the trail likely picked up steam.

The Gray Area Between Observation and Profiling

Zwinck told investigators he doesn’t photograph everyone’s ID. He looks for “behavior changes, or abnormalities,” which to him, signal something might be off.

What exactly those “abnormalities” were in Goncalves’ case isn’t clear. But it raises serious concerns about discretionary policing and the invisible line between proactive law enforcement and racial or immigration profiling.

One sentence in his interview stood out starkly:
“I took a photo of her driver’s license… sent that out to a Signal chat group.”

That single act kickstarted a chain reaction.

Sheriff’s Office Wraps Investigation, Issues Discipline

Now that the internal Administrative Review is over, the department has confirmed disciplinary action was taken against Zwinck. But the exact nature of the discipline hasn’t been disclosed.

That’s been frustrating for some in the community. The Sheriff’s Office maintains it can’t legally share details about personnel matters. Still, many are calling for transparency.

The statement also noted that while the deputy violated internal policy, there’s no evidence of criminal wrongdoing. Sheriff Rowell emphasized the need for stricter guardrails to ensure this sort of situation doesn’t repeat.

ICE Wasn’t Watching the Road… But They Were Listening

ICE confirmed they weren’t part of the group chat where Zwinck shared the photo. But that doesn’t mean they didn’t receive the tip secondhand.

This is where things get murky. Information passed between agencies — even informally — can set off formal immigration enforcement. That’s what seems to have happened here.

While Homeland Security has access to national databases, border records, and more, Goncalves’ encounter with the federal agency came just days after Zwinck’s chat message. Coincidence? Possibly. But many believe otherwise.

Legal, But Not Ethical? A Growing Debate

The entire incident shines a light on a legal gray zone that local law enforcement agencies are increasingly navigating across the country.

Is sharing ID information via encrypted chat technically illegal? No, according to internal reviews. But does it violate public trust? That’s a harder question.

Here’s a snapshot comparison of relevant policies across Colorado counties:

Some counties have clear guidelines. Others leave a lot up to interpretation — and that can lead to serious fallout.

Goncalves’ Detention: A Flashpoint Moment

Caroline Dias-Goncalves’ case isn’t isolated. It’s part of a broader national conversation about the role of local cops in immigration enforcement.

One small action — a photo sent in a chat — changed the course of a young woman’s life.

Immigration rights groups have pointed to this case as an example of how law enforcement can unintentionally funnel individuals into the federal immigration system, even without direct intent.

Even without ICE in the group chat, the connection between local stops and federal detentions is very real.
