Jury Convicts Former National Guard Task Force Member for Illegal Firearm Possession Offenses That Came to Light During an Investigation into Leaks of Sensitive Operational Information

SACRAMENTO, Calif. — A federal jury on Tuesday found Ruby Celly Uribe, 37, of Sacramento, guilty of unlawfully possessing a machine gun and possessing an unregistered short‑barreled rifle, U.S. Attorney Eric Grant announced.

With certain exceptions, federal law prohibits the possession of machine guns and unregistered rifles with barrels shorter than 16 inches.

According to court documents and evidence presented at a trial, Uribe was assigned to the logistics shop at the California National Guard Headquarters in Mather, California, and was a member of the Counterdrug Task Force (CDTF). The CDTF supports local, tribal, and federal law enforcement entities in the interdiction of drug trafficking organizations. While assigned to this unit, Uribe leaked information about upcoming drug raids to a person she knew to be involved with drug dealing. Text messages recovered from Uribe’s and the drug dealer’s phones revealed she shared sensitive information about upcoming operations, including the date and location and the number of military vehicles and aircraft involved.

A federal search warrant of Uribe’s residence resulted in the discovery of a short-barreled rifle. The firearm had been modified to fire in full-automatic mode as a machine gun. In addition, it was a privately made firearm with no serial number, commonly referred to as a ghost gun. A search of Uribe’s cellphone revealed that she was also engaged in trafficking other non‑serialized, short-barreled machine guns, including to a coworker on July 20, 2022.

During preparation for trial in this case, the FBI learned of another illegal firearm that Uribe sold in August 2022. The FBI safely recovered that firearm, which is also a machine gun and short-barreled rifle. 

The Federal Bureau of Investigation and the Bureau of Alcohol, Tobacco, Firearms and Explosives conducted the investigation with assistance from the California Military Department. Assistant U.S. Attorneys Adrian T. Kinsella and Nicole M. Vanek are prosecuting the case.

Uribe is scheduled to be sentenced by U.S. District Judge Dena Coggins on Sept. 11, 2026. Uribe faces a maximum statutory penalty of 10 years in prison and a $250,000 fine. The actual sentence, however, will be determined at the discretion of the court after consideration of any applicable statutory factors and the federal Sentencing Guidelines, which take into account a number of variables.

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, and protect our communities from the perpetrators of violent crime.
