DENVER (KDVR) — The Mesa County Sheriff's Office says that it was not involved with immigration enforcement efforts after learning that a "communication group" that included some of the agency's deputies may have been used for immigration purposes.

The information included in the group was intended for drug interdiction and anti-drug trafficking efforts, according to the sheriff's office, but instead was allegedly used by federal representatives to "extrapolate immigration information for the purposes of ICE enforcement."

Local law enforcement, including county and state peace officers, are prevented under Colorado law from working with ICE, or U.S. Immigration and Customs Enforcement, for the purpose of civil immigration detainers. In May, the U.S. Department of Justice filed a lawsuit challenging Colorado's laws restricting law enforcement from working with federal officers for civil immigration detainers.

On Monday, the agency said that on June 5, a Mesa County Sheriff's Office deputy conducted a traffic stop on a black sedan on Interstate 70 outside of Loma. The office released redacted body-worn camera footage of the traffic stop on Monday, showing that the interaction lasted about 19 minutes and that the driver, Caroline Dias Goncalves, was released from the stop with a written warning.

According to reporting by the Salt Lake Tribune, Dias Goncalves is a 19-year-old University of Utah student and is now being held by ICE at the Aurora contract detention facility run by the GEO Group.

"In accordance with Colorado law, the Mesa County Sheriff’s Office does not investigate residency status during any law enforcement interactions," the Mesa County Sheriff's Office stated. "Our Deputy was part of a communication group that included local, state, and federal law enforcement partners participating in a multi-agency drug interdiction effort focusing on the highways throughout Western Colorado. We were unaware that the communication group was used for anything other than drug interdiction efforts, including immigration."

The sheriff's office said that since this incident, all members of the sheriff's office have been removed from the communication group. An administrative investigation showed that the federal representatives in the group had begun using the materials collected for drug trafficking efforts for immigration arrests, which the sheriff's office said is "contradictory to Colorado law."

The footage of the Mesa County Sheriff's Office traffic stop was posted online on Monday evening. Dias Goncalves can be heard telling the officer that she's been living in Utah for over a decade, but was born in Brazil.

She told the officer she was visiting her boyfriend, and the officer told her to be more careful when driving near semitrailers. He had initially pulled her over for cutting off a big rig, leading it to have to engage its brakes.

"We would like to reiterate that we were unaware that the communication group was used for anything other than drug interdiction efforts and that we have since removed all Mesa County Sheriff’s Office members from the communication group," the Mesa County Sheriff's Office stated. "We will continue our coordination on drug interdiction efforts with our state and federal and state partners within Colorado law."

On Tuesday, FOX31's Nexstar partner station in Grand Junction learned of immigrant rights groups that were calling for deeper scrutiny of the matter.

"We are deeply concerned by reports that a Colorado law enforcement [officer] passed private identifying information to ICE in violation of Colorado law designed to defend our communities. No one should have to live in fear that a routine traffic stop could lead to ICE detention. Now, Caroline and her family are going through unimaginable suffering that could have been prevented if our laws were followed," said Raquel Lane-Arellano, Communications Manager with the Colorado Immigrant Rights Coalition, in a press release.

The Grand Junction station also reached out to the Colorado Governor's Office for comment regarding Dias Goncalves' case.

"It’s deeply disappointing to see that the federal government is not focusing on dangerous criminals, which bipartisan Colorado leaders are calling for, but instead detaining a thriving college student, with no criminal history, who is by all accounts in this country legally. Reports show Ms. Goncalves is a DREAMer and therefore, would be legally allowed to be in our great country. The Governor urges the federal government to immediately release Ms. Goncalves, calls for more transparency into how immigration operations are being conducted in our state, and continues to call on Congress to do their part and pass real immigration reform that provides a pathway to citizenship and secures the border,” said a governor's office public information officer.

On Sunday, President Donald Trump directed federal immigration officers to prioritize deportation in Democratic-run cities.
