An undocumented migrant described by prosecutors as an “anti-ICE agitator” pleaded guilty Tuesday in San Diego federal court to charges related to impersonating a Border Patrol agent and possessing firearms he was not legally allowed to own, according to prosecutors and court records.
Jaime Ernesto Alvarez Gonzalez, a 53-year-old Mexican citizen, faces up to 15 years in prison on each of the three firearms charges. The U.S. Attorney’s Office in San Diego said Alvarez overstayed a tourist visa decades ago and has no lawful status in the U.S. He’s expected to be deported to Mexico after serving his sentence.
An attorney for Alvarez from Federal Defenders of San Diego did not immediately respond Tuesday to a message seeking comment.

Prosecutors alleged that Alvarez disrupted an immigration enforcement operation in January in Linda Vista while wearing clothing similar to that of immigration agents and while driving a black Ford pickup decked out in law enforcement accessories, including communications antennae and a light bar. When federal agents arrested him about a week later, he was allegedly driving a different vehicle that had a light bar and an FBI hat on its dashboard, and he was allegedly carrying a fake FBI identification card, according to a court filing by prosecutors.
During a later search of his San Diego home, agents also found license plates with “CIA,” “INTERPOL” and “SHERIFF” printed on them, a U.S. Customs and Border Protection “no trespassing” sign that appeared to be stolen, as well as other law enforcement paraphernalia, according to a March 16 detention memorandum in which prosecutors successfully sought to keep Alvarez in custody without bail.
Investigators also alleged that Alvarez purchased multiple firearms over the years by lying about his citizenship status on government forms he was required to fill out to complete the purchases, according to the detention memorandum. Agents were able to track down one of the guns, a 9mm Glock handgun, but said they were unable to locate other weapons, including high-powered rifles he’d been recently photographed using.
Alvarez’s plea agreement was not immediately available late Tuesday, so it was unclear exactly which facts he admitted to.
The incident that landed Alvarez on law enforcement’s map occurred Jan. 8 when he allegedly began following a real Border Patrol agent through Linda Vista while driving a black Ford F-150 decked out in law enforcement accessories. In addition to the antennae on the roof — which prosecutors said was non-functioning — and the light bar on the dash, the truck also had handcuffs hanging from the rearview mirror, a “United States Border Patrol” sticker on the front windshield and a license plate holder that read “Ferderal (sic) Truck,” according to prosecutors and documents in the case.
The legitimate Border Patrol agent, who was working on a U.S. Immigration and Customs Enforcement task force, “was forced to abandon his law enforcement mission” out of concern that Alvarez might be a real federal agent working on a different assignment in the same area, according to the detention memorandum.

The U.S. Attorney’s Office said in a statement that this is known as “deconflicting” and is a step that law enforcement officers will take when other law enforcement officers might potentially be working in the same area. It is used “to ensure officer safety, to prevent compromising investigations, to avoid confusion, and to promote public safety,” prosecutors said.
Alvarez, who was wearing a mask covering his face and a “thin green line” hat associated with Border Patrol agents and their supporters, allegedly continued following the legitimate Border Patrol agent into a parking lot, according to prosecutors and court filings.
When other federal officers arrived as backup to investigate, Alvarez allegedly “caused a public commotion and aggressively told officers to leave his community,” according to the March 16 detention memorandum. “The federal officers departed the scene and were chased by three additional vehicles on the highway which (Alvarez) labeled his ‘reinforcements.’”
Prosecutors alleged that Alvarez video-recorded and narrated the entire incident, and said during the recording that he was actively looking for federal officers involved in deportation missions.
Prosecutors also alleged that while in custody, Alvarez directed another person to destroy evidence. He also allegedly flew to Texas in 2025 and rented a firearm at a gun range there, an incident prosecutors said has led to a separate federal investigation in Texas.
Alvarez remains in custody and is set to be sentenced in July.
