Mexican National Indicted on Firearm and Immigration Charges

TUCSON, Ariz. – On Wednesday, a federal grand jury in Tucson returned a 5-count indictment against Teodoro Diaz-Ochoa, 44, of Mexico, for Felon in Possession of a Firearm and Ammunition, Alien in Possession of a Firearm and Ammunition, and Reentry of a Removed Alien. 

The charging documents filed in the case allege that Diaz-Ochoa is an alien, illegally present in the United States, who was previously convicted of felony Attempted Sexual Assault and last removed from the United State on April 22, 2016. On January 22, 2025, Arizona Game and Fish Officers encountered Diaz-Ochoa while conducting a hunting without a license investigation. Diaz-Ochoa was found in possession of a Savage bolt action rifle and 80 rounds of various ammunition. On March 26, 2025, the Bureau of Alcohol, Tobacco, Firearms and Explosives executed a federal search warrant at Diaz-Ochoa’s residence, where they discovered a Remington semi-automatic shotgun and 18 rounds of various ammunition.  

A conviction for the firearm and ammunition charges carries a maximum penalty of 15 years in prison and a fine of up to $250,000. A conviction for the reentry of a removed alien charge carries a maximum penalty of 20 years in prison and a fine of up to $250,000. 

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN). 

An indictment is simply a method by which a person is charged with criminal activity and raises no inference of guilt. An individual is presumed innocent until evidence is presented to a jury that establishes guilt beyond a reasonable doubt. 

The Bureau of Alcohol, Tobacco, Firearms and Explosives conducted the investigation in this case. Assistant U.S. Attorney Mary Sue Feldmeier, District of Arizona, Tucson, is handling the prosecution.
