Illegal Possession and Firearms Sales Land Oklahoma City Men in Federal Prison for More Than 19 Years Collectively

OKLAHOMA CITY – AUSTIN GAGE OSBORN, 24, of Oklahoma City, has been sentenced to serve 68 months in federal prison for engaging in the business of dealing firearms without a license and being a drug user in possession of firearms, announced U.S. Attorney Robert J. Troester. 

According to public record, beginning in July 2024, undercover agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) began purchasing firearms from Osborn and codefendant JOSE ADRIAN HERMOSILLO, 22, of Oklahoma City. Agents identified Hermosillo as a convicted felon who was prohibited from possessing firearms. Between July 17, 2024, and August 9, 2024, ATF agents met with Osborn and Hermosillo on several occasions purchasing approximately 20 firearms.  In one specific transaction on July 29, 2024, undercover agents told Osborn and Hermosillo that the guns the agents were purchasing would be transported out of the United States and into Mexico. Despite having reason to believe that the firearms would be trafficked across the border, Osborn and Hermosillo continued to sell firearms to undercover agents for profit, without a federal firearms license, in violation of federal law. 

On November 26, 2024, Osborn was charged by Superseding Information with engaging in the business of dealing firearms without a license and with being a drug user in possession of firearms. On December 5, 2024, Osborn pleaded guilty to the Superseding Information, and admitted he possessed 19 firearms while being a regular user of marijuana, and that he was illegally dealing firearms as a business without a license to do so. At the sentencing hearing on March 26, 2025, U.S. District Judge Scott L. Palk sentenced Osborn to serve 68 months in federal prison, followed by three years of supervised release.

Hermosillo pleaded guilty on November 26, 2024, to trafficking firearms, and admitted he willingly transferred firearms to another person with reasonable cause to believe that the use, carrying, or possession of the firearms by the recipient would constitute a felony. Hermosillo was sentenced on March 24, 2025, to serve 168 months in federal prison, followed by three years of supervised release.

In announcing the sentences for Osborn and Hermosillo, Judge Palk noted the seriousness of these offenses, the need for the sentences to deter others in the public who may consider engaging in similar behavior, and the history and characteristics of the defendants. Public record further reflects that Hermosillo has previous felony convictions in Oklahoma County that include attempted burglary in case number CF-2021-2066 and possession of a firearm after juvenile adjudication in case number CF-2022-3560.

This case is the result of an investigation by the ATF and the Oklahoma City Police Department. Assistant U.S. Attorneys Drew E. Davis and Mary E. Walters prosecuted the case.
