Wyoming Sheriff Releases Immigration Arrest Video After Legal Challenge Over Evidence Access

Why It Matters

A dispute over law enforcement access to arrest records has prompted Wyoming’s Laramie County Sheriff’s Office to reverse course and release video footage of an immigration arrest. The case raises questions about transparency in deportation proceedings and the balance between investigative access and public records in immigration cases.

What Happened

The Laramie County Sheriff’s Office handed over video footage documenting an immigration arrest following a court hearing Thursday, after initially refusing to provide the material to attorneys representing the arrested individual. Drake Hill, an attorney with Lichter Immigration law firm, announced receipt of the footage, which arrived on a thumb drive that also included a supplemental report filed by the deputy involved in the arrest.

The case centers on Mario Fabian Valenzuela Robles, a Mexican citizen with three children who was arrested after being stopped by a sheriff’s deputy. Lichter Immigration and investigator Kevin Lewis filed a complaint last month alleging the sheriff’s office had blocked access to evidence needed in deportation proceedings and had distributed a false report about the arrest before issuing a correction.

Sheriff Brian Kozak, accompanied by chief deputies Perry Rockvam and Aaron Veldheer, appeared at Thursday’s hearing before Judge Robin S. Cooley. The judge ordered a certified computer search to locate the requested records and directed an “in camera” review—where a judge privately examines materials—of certain documents sought by the law firm.

County Attorney Mark Voss stated the office had not received confirmation that Lichter Immigration represented Valenzuela Robles until Lewis provided a retainer letter on the law firm’s letterhead during the legal proceedings. Once Voss determined the representation was legitimate, he authorized release of the arrest video.

Immigration detention and deportation cases frequently hinge on documentation and video evidence, particularly body camera footage that may corroborate or contradict accounts of how arrests were conducted. Access to such records has become an increasingly contested issue as immigration enforcement intersects with transparency and due process concerns.

Wyoming law does not currently require law enforcement agencies to make arrest recordings publicly available. The dispute in Laramie County reflects broader tensions between agencies’ control over records and attorneys’ need to access evidence for legal proceedings involving detained clients.

According to prior reporting, Wyoming law enforcement transferred 87 people to Immigration and Customs Enforcement custody over a 13-month period, underscoring the volume of immigration cases flowing through state and local detention systems.

What’s Next

Sheriff Kozak announced the office will no longer permit in-person video inspections unless a court order is obtained. The department plans to develop a formal written policy communicating this requirement to attorneys and the public.

Drake Hill characterized the initial refusal to provide records as serious misconduct, stating that “blocking” access to evidence in deportation proceedings “rises to the highest level of law enforcement misconduct.” County Attorney Voss cautioned that once records enter the public domain, control over their distribution becomes impossible, noting “once they are out in the world, there is no pulling them back.”

Valenzuela Robles is listed as represented by Lichter Immigration in his ongoing habeas corpus case, which continues to move through Colorado courts.
