Three Sureño Street Gang Associates Charged with Felon in Possession of a Firearm

PORTLAND, Ore.— Three men associated with the Sureño street gang have been charged with felon in possession of a firearm after the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) engaged in multiple undercover purchases of firearms and machine gun conversion devices.

Cesar Daniel Arevalo, 36, of Portland, Oregon and Jose Luis Brown Ceballos, 35, and Jose Luis Diaz Ceballos, 24, of Salem, Oregon, have been charged by criminal complaint with Felon in Possession of a Firearm.

According to court documents, from July 2025 through November 2025, ATF undercover agents engaged in multiple undercover purchase operations involving Arevalo and his associates. Undercover agents purchased a total of 15 firearms (four modified to machineguns), 58 machine gun conversion devices, and cocaine from Arevalo and his associates, including Diaz Ceballos.

On November 13, 2025, Arevalo, Brown Ceballos, Diaz Ceballos, and a juvenile conducted an armed protection of an undercover narcotics transaction in Salem. When the transaction was completed, the armed suspects were arrested by ATF agents. Four firearms were recovered from the scene.

The ATF and the Federal Bureau of Investigation are investigating the case. Assistant U.S. Attorney Nicole Bockelman is prosecuting the case.

A criminal complaint is only an accusation of a crime, and a defendant is presumed innocent unless and until proven guilty.

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 Department 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.
