Federal authorities in San Diego have long alleged that brothers René and Alfonso Arzate Garcia are high-ranking members of the Sinaloa cartel who, for roughly 15 years, have used violence and corruption to control key drug-trafficking routes from Baja California into San Diego.
On Thursday, officials took their boldest step yet to publicly ratchet up the pressure on the brothers, who were first indicted in San Diego in 2014, announcing $5 million bounties for information leading to their capture. U.S. Attorney Adam Gordon also unsealed a new narco-terrorism indictment against René Arzate, the younger of the siblings, alleging that in recent years he has climbed the ranks of the Sinaloa cartel to become one of the group’s “most prolific drug traffickers and enforcers.”
Leaders of the FBI and Drug Enforcement Administration’s San Diego field offices promised that René Arzate — a 42-year-old known as “La Rana,” or “The Frog” in English — will soon be captured and face justice.
“René Arzate Garcia’s days as a narco-terrorist are numbered,” James Nunnallee, DEA San Diego’s acting special agent in charge, said during a Thursday news conference. “His days as a plaza boss for the Sinaloa cartel … are numbered.”

The Arzate brothers were previously designated as drug kingpins in 2023 by the Department of the Treasury’s Office of Foreign Assets Control.
The new actions announced Thursday were not directly related to Sunday’s killing of Nemesio “El Mencho” Oseguera Cervantes, the purported leader of the Jalisco New Generation Cartel, or CJNG. But the Arzate brothers and their faction of the Sinaloa cartel have for years allegedly been in a bloody conflict across Baja California with an opposing faction of the Sinaloa cartel that had reportedly allied with the CJNG.
That violence has at times spilled over the border into San Diego, including in early 2024, when three shootings left two people dead and one wounded. The Union-Tribune previously reported that those shootings targeted two cartel figures with ties to the CJNG-aligned faction of the Sinaloa cartel that was allegedly at war with the Arzate brothers’ faction.
Prosecutors secured the new superseding indictment against René Arzate charging him with terrorism-related crimes in October, according to the unsealed indictment. Such charges have only been available to prosecutors since early last year, when the Trump administration designated the Sinaloa cartel and five other Mexican criminal groups as Foreign Terrorist Organizations and Specially Designated Global Terrorists.
Federal prosecutors in San Diego were the first in the nation last year to allege a narco-terrorism case against suspected Mexican drug traffickers and have promised to use such charges to try to dismantle and apply pressure to the Sinaloa cartel. During a news conference last May announcing the first case, Gordon, the U.S. attorney in San Diego, said the cartel’s leaders had gone from being the hunters to the hunted.
Gordon expounded on that Thursday, describing how U.S. enforcement is creating a bleak future for the cartel’s leaders that’s likely to end with disloyalty and the inside of a U.S. prison.
“The remaining free members of the Sinaloa cartel have become liabilities to each other — each knows too much about the other,” Gordon said. “In that world, betrayal becomes not a question of ‘if,’ but ‘when?’ To those cartel leaders who remain at large, here’s the question: Who can you trust when you can’t trust anyone?”
A newly unsealed court document in René Arzate’s case alleged that he is a “high-ranking, hyper-violent Sinaloa Cartel lieutenant” who for 15 years has “brutally controlled the Tijuana Plaza” alongside his brother, known by the alias “Aquiles.” Prosecutors allege that the brothers used “murder, kidnappings, extortion and corruption” of politicians, military leaders and police officials to keep control of their territory.
Prosecutors alleged that the brothers are part of a Sinaloa faction loyal to one of its longtime leaders, Ismael “El Mayo” Zambada, who is now in U.S. custody, and his sons, who are known as “Los Mayitos.” Factions of the group loyal to Zambada and the Mayitos have for years been in a violent and protracted power struggle with factions loyal to the group’s other longtime leader who is also in U.S. custody, Joaquín “El Chapo” Guzmán, and his sons, known as “Los Chapitos.”
René Arzate has been a “key contributor in the ongoing bloody conflict” between the Mayitos and Chapitos, prosecutors wrote in a motion to unseal the new indictment.
“René Arzate has provided fighters, weapons, and money during the conflict,” prosecutors wrote in the motion. “He has also engaged in violent confrontations with the Chapitos faction and leveraged the conflict to take additional territory within Baja California and Sinaloa and increase his influence within the Sinaloa Cartel.”

The document contains more than a dozen images stemming from the investigation of René Arzate, many of them showing seizures of drugs and military-style weapons allegedly linked to him.
Other images, apparently taken from social media, show heavily armed groups of men or the aftermath of a violent death adorned with frog emojis, apparent references to René Arzate’s nickname. Another image shows a seizure from a home featuring a grenade launcher lying next to a poster adorned with the image of a cartoon frog and the words “Cartel de la Rana.”
The new indictment charges René Arzate with narco-terrorism, providing material support to terrorism and more traditional charges linked to suspected drug traffickers, including drug conspiracy counts and a charge of engaging in a continuing criminal enterprise. Several of the charges carry maximum penalties of life in prison if he is ever captured and prosecuted in the U.S.
