July 21, 2025 – A federal grand jury returned a three-count indictment on Thursday, July 17, 2025, against Rueben Paul Phill, 41, of Tracy, charging him with illegal firearms trafficking and two counts of being a felon in possession of firearms, Acting U.S. Attorney Kimberly A. Sanchez announced.

According to court documents, between Aug. 22, 2023, and Aug. 27, 2024, Phill trafficked firearms with Alejandra Susana Castillo, 34, of Tracy, by purchasing them in Nevada and selling them on the black market in California.

On July 27, 2024, Phill led a law enforcement officer on a high-speed chase in excess of 100 miles per hour. The officer ultimately ended the pursuit for public safety concerns. Two days later, another officer observed the car parked at a gas station. The officer detained Castillo, who was then using the car. During a search of the vehicle, the officer discovered a semi-automatic rifle in the trunk, along with three extended magazines.

In total, more than 30 firearms were traced to this conspiracy. At least three of these firearms have been recovered in connection with suspected firearm-related crimes. One such firearm, for example, was recovered in the possession of a felon in Vallejo on July 25, 2024, only three days after Castillo purchased the firearm in Nevada on July 22, 2024.

Castillo pleaded guilty to illegal firearms trafficking on Jan. 31, 2025, and is scheduled to be sentenced on Aug. 1, 2025.

This case is the product of an investigation by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the California Highway Patrol, the Pleasonton Police Department, the Reno Police Department, the Tracy Police Department, and the San Joaquin County District Attorney’s Office. Assistant U.S. Attorney Adrian T. Kinsella is prosecuting the case.

If convicted, Phill faces a maximum statutory penalty of 15 years in prison and a $250,000 fine on each count. Any sentence, however, would 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. The charges are only allegations; Phill is presumed innocent until and unless proven guilty beyond a reasonable doubt.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the U.S. Department of Justice launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to combat 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).
