Illegal Alien Sentenced For Possessing Firearm

MUSKOGEE, OKLAHOMA – The United States Attorney’s Office for the Eastern District of Oklahoma announced that Salvador Diaz-Hermosillo, age 39, a Mexican national unlawfully present in the United States, was sentenced to 6 months in prison for one count of Illegal Alien in Possession of a Firearm.

The charge arose from an investigation by the Sallisaw Police Department, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the U.S. Department of Homeland Security’s Immigration and Customs Enforcement Division.

On March 12, 2025, Diaz-Hermosillo pleaded guilty to the charge.  According to investigators, on January 31, 2025, Diaz-Hermosillo, an alien illegally and unlawfully in the United States, who knew of his status, knowingly possessed a semi-automatic rifle within the Eastern District of Oklahoma.

Illegal aliens are prohibited from possessing firearms or ammunition pursuant to Title 18, United States Code, Section 922(g)(5).

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).

The Honorable Ronald A. White, Chief U.S. District Judge in the United States District Court for the Eastern District of Oklahoma, presided over the hearing.  Diaz-Hermosillo was remanded into the custody of the U.S. Marshals Service pending transportation to a designated United States Bureau of Prisons facility to serve a non-paroleable sentence of incarceration.
