Mexican National with Prior Drug Trafficking Conviction Sentenced

TULSA, Okla. - A Mexican national was sentenced today for unlawfully residing in the United States and possessing a loaded firearm, announced U.S. Attorney Clint Johnson.

U.S. District Judge Rodney W. Sippel sentenced Bryan Abisai Costeira Hernandez, 28, for being a Felon in Possession of a Firearm and Ammunition and Unlawful Reentry of a Removed Alien. Costeira Hernandez was ordered to serve 41 months' imprisonment, followed by two years of supervised release. Upon release, Costeira Hernandez is expected to face removal proceedings.

According to court documents, in January 2026, Costeira Hernandez was pulled over for a traffic violation. Unable to verify the identification that Costeira Hernandez provided to officers, he was detained. Officers searched the vehicle and found a loaded firearm and drugs. After officers placed him in handcuffs, Costeira Hernandez attempted to run away from the officers. While transporting Costeira Hernandez to jail, he told officers that he provided a false name and admitted that he was previously deported for unlawfully being in the United States.

State court records show that Costeira Hernandez has several pending charges, including possessing a stolen vehicle, obstruction, and possession of a controlled substance. Costeira Hernandez previously pleaded guilty in two separate felony cases for possessing a stolen vehicle, trafficking illegal drugs, resisting, obstruction, among other charges. In both cases, he received suspended sentences and was removed from the United States in 2022.

Costeira Hernandez will remain in custody pending transfer to the U.S. Bureau of Prisons.

The Bureau of Alcohol, Tobacco, Firearms and Explosives and Homeland Security Investigations investigated the case. Assistant U.S. Attorney Augustus Forster prosecuted the case.
