A serious legal challenge has emerged in Laramie County, where a lawsuit filed this week accuses Sheriff Brian Kozak and his office of obstructing justice. The litigation centers on the case of Mario Fabian Valenzuela Robles, a long-time Laramie County resident and Mexican citizen currently facing deportation. The plaintiffs—an investigator and a Colorado-based immigration law firm—allege that the Sheriff’s Office blocked access to vital evidence that could prove pivotal to Valenzuela Robles’ defense. According to the complaint, the office’s refusal to turn over records has already hampered legal proceedings, prompting the plaintiffs to seek an emergency hearing and court-mandated release of all materials related to the man’s traffic stop and subsequent detention.
The heart of the controversy involves a deeply troubling discrepancy between two official reports issued by the Sheriff’s Office. Following an initial inquiry into Valenzuela Robles’ arrest, the department produced a report claiming a local Cheyenne police officer had assisted in the traffic stop. However, representatives from the Cheyenne Police Department flatly rejected this account, noting that the officer in question was on leave at the time and labeling the sheriff’s documentation a “complete fabrication.” This initial report even contained errors regarding the gender of the officer mentioned. When pressed, the Sheriff’s Office eventually retracted the document and issued a “revised” version that fundamentally altered the narrative, claiming the stop was conducted by a different official and insisting that key body-camera footage, which was absent from the first report, did exist.
This administrative confusion has naturally fueled accusations of transparency failures. The plaintiffs allege that the Sheriff’s Office repeatedly gave their investigator, Kevin Lewis, contradictory information, claiming at various times that no records existed, that the office had no involvement in the arrest, and that video footage was inaccessible. Even after a June appointment was scheduled for the legal team to view the requested camera footage, the office abruptly canceled the meeting without notice, directing the attorneys back to the county attorney. Throughout this process, Sheriff Kozak has largely deflected inquiries, referring all questions to the Laramie County Attorney’s Office and maintaining that his department is following standard protocols regarding public records.
For those involved in the case, the experience has been marked by a sense of deep frustration and bewilderment. Valenzuela Robles, recognized by those who know him as a hard-working individual integral to the local community—he even performed framing work on the very ICE facility where he was later detained—is currently free on bond. His legal counsel, Laura Lichter, a seasoned immigration attorney, expressed shock at the lack of cooperation, noting that she had never before encountered such difficulty in obtaining records for a case in Wyoming. The irony is not lost on the defense team, who view the situation as a stark departure from the accountability expected of local law enforcement.
The lawsuit sits in the shadow of a broader legal battle involving the Laramie County Sheriff’s Office’s controversial 287(g) agreements with U.S. Immigration and Customs Enforcement (ICE). These agreements, which empower local deputies to function as federal immigration agents, are the subject of another recent lawsuit filed by the ACLU, which challenges the legality of these partnerships. Since October, the Laramie County Sheriff’s Office has carried out over 400 immigration-related arrests, making it one of the most proactive agencies in the state regarding federal enforcement. Critics argue that this aggressive stance, combined with the administrative inconsistencies highlighted in this new lawsuit, demonstrates a concerning trend regarding oversight, accuracy, and the treatment of long-standing community members.
As the legal proceedings move forward, the case highlights the high stakes for both the defendant and for public trust in local institutions. With Sheriff Kozak facing a reelection campaign, the scrutiny on his office’s policies and record-keeping is intensifying. The plaintiffs hope that an expedited court review will force the disclosure of the evidence they believe is being suppressed, potentially shedding light on whether the discrepancies in the arrest reports were mere clerical errors or a calculated move to obstruct a legal defense. For now, the case remains an open wound in the community, reflecting a national debate over the scope of local police power and the fundamental rights of immigrants living and working in American towns.
