Colorado AG Sues Sheriff’s Deputy for Cooperating With Federal Immigration Officials
1st August 2025
Colorado Attorney General Phil Weiser sued Mesa County Sheriff’s Deputy Alexander Zwinck last week after Zwinck reportedly sent federal agents information about a student present in the U.S. illegally, The Associated Press first reported.
Zwinck and another deputy, Erik Olson, have also been placed on unpaid leave; Zwinck for three weeks and Olson for two weeks.
On June 5, Zwinck is reported to have pulled Caroline Dias-Goncalves over for a traffic stop. The officer gave Dias-Goncalves, a college student from Brazil with an expired visa, a warning but shortly after, federal immigration officers stopped Dias-Goncalves and arrested her.
A Mesa County Sheriff’s Office internal investigation found that Zwinck and Olson were a part of a Signal group chat that included Immigration and Customs Enforcement officers. Both deputies are reported to have used the Signal chat to relay information to federal officers.
