Laramie County sheriff's report on an immigration arrest named a cop who was on leave
After a sheriff's deputy arrested Mexican national Mario Fabian Valenzuela-Robles, a father of three U.S.-citizen children, on April 23, 2026, the Laramie County Sheriff's Office released a report saying a Cheyenne police officer made the stop and the deputy's body camera was off. A Cheyenne police records staffer called it a "complete fabrication"; the officer named was on leave that day. A revised report said Chief Deputy Chance Walkama made the stop and his camera was recording. An immigration law firm sued in June for the records; Judge Robin Cooley ordered Sheriff Brian Kozak to produce them in July, and the office missed the deadline, withheld documents without a log and produced unreadable files. On Oct. 27 Cooley declined to hold Kozak in contempt, finding no proof it was willful, but said the failure prolonged the dispute and gave him 10 days to comply. Kozak called the suit politically motivated.
We refer those to the county attorney's office to deal with those public records requests.
You cannot know about a court deadline and not meet that deadline without intentionality.
Plaintiffs have not proven by clear and convincing evidence that the failure to comply was willful,
"The law says you have to willfully, you know, withhold the evidence, and so of course we didn't do that."
County Attorney Mark Voss said a deputy confused this stop with a later one, and the error was corrected.
No outcome recorded yet.
