Four Former Oakdale-Area Law Enforcement Leaders and One Business Owner Plead Guilty to Falsifying Police Reports and Bribery to Perpetrate Decade-Long Visa Fraud Conspiracy

ALEXANDRIA - On June 30, 2026, Glynn Dixon, 62, of Forest Hill, pled guilty in federal court for his role in a decade-long scheme involving bribery and a conspiracy to commit visa fraud and mail fraud after his four co-conspirators, Chandrakant Patel, 40, of Oakdale, Chad Doyle, 55, of Oakdale, Michael Slaney, 64, of Oakdale, and Tebo Onishea, 38, of Glenmora, each pled guilty to the same in recent weeks. The defendants were originally indicted on July 2, 2025. Dixon, Doyle, Onishea, and Slaney each face up to 5 years in prison. Patel faces up to 20 years in federal prison.

At the time of the offenses, four of the defendants were serving in high-profile law enforcement positions: Doyle as Oakdale Chief of Police; Slaney as Oakdale Marshal for Ward 5; Dixon as Forest Hill Chief of Police; and Onishea as Glenmora Chief of Police. Patel was a business owner.

"These defendants' disgraceful fraud endangered our community and undermined the public trust in the immigration system solely to line their own pockets," said United States Attorney Zachary A. Keller. "These guilty pleas confirm the depth of corruption uncovered here and the strength of the evidence developed during an incredible investigation by our law enforcement partners working together, and our Office looks forward to advocating for prison time for each defendant that reflects the seriousness of the crimes they committed."

"HSI is committed to protecting the integrity of our immigration system and lawful immigration benefits," said Matt Wright, Acting Special Agent in Charge of Homeland Security Investigations, New Orleans. "When anyone, including public officials, exploits immigration relief programs or commits fraud against the government, HSI and our law enforcement partners will investigate, dismantle these schemes, and work to bring those responsible to justice."

"These guilty pleas demonstrate accountability for officials who breach public trust and misuse federal systems," said Internal Revenue Service-Criminal Investigations Special Agent in Charge Demetrius Hardeman, of the IRS-CI Atlanta field office.

"The FBI will continue to work with our federal partners and the U.S. Attorney's Office to ensure people who engage in this type of corrupt criminal activity are brought to justice," said Special Agent in Charge Jonathan Tapp of the FBI's New Orleans Field Division.

The case involves the abuse of U nonimmigrant status, or "U-Visas." Congress created the U-Visa with the passage of the Victims of Trafficking and Violence Protection Act in October 2000. The legislation was intended to strengthen the ability of law enforcement agencies to investigate and prosecute crime while also protecting victims of crimes who are willing to help law enforcement authorities in the investigation or prosecution of that criminal activity. Foreign nationals are eligible for a U-Visa if they meet certain criteria, including but not limited to, if they were a victim of qualifying criminal activity that occurred in or violated laws of the United States, or possessed information about the criminal activity.

According to court documents, the defendants engaged in U-Visa fraud from December 2015 through July 2025 by fabricating police reports that falsely documented armed robberies that never occurred and then providing these fictitious reports to noncitizens who used them to support fraudulent U-Visa applications. The foreign nationals pursuing U-Visas would pay Patel thousands of dollars to be named as "victims" in these fabricated incidents, and Patel then secured false police reports by coordinating with defendants Doyle, Slaney, Dixon, and Onishea, each of whom used their positions in law enforcement to certify the fraudulent reports. Court records also show that Patel attempted to bribe an agent of the Rapides Parish Sheriff's Office with $5,000 in February 2025 to obtain such a report. In addition, the defendants submitted falsified documents via the U.S. Postal Service and other carriers, constituting additional mail fraud charges.

U.S. Attorney Zachary A. Keller for the Western District of Louisiana made the announcement.
