"El Sierra 1" and "El Sierra 2" Busted: CJNG-Linked Brothers Charged with Murder, Kidnapping, Extortion

The Siglo XXI highway cuts through the hills of Michoacan, a ribbon of asphalt connecting the state's mountain towns to the hot lowlands. On Wednesday afternoon, a stolen Chevrolet moved south along that road carrying Alfredo "N," alias "El Sierra 2," his girlfriend, and a loaded M4 assault rifle with 27 grams of methamphetamine wedged into the cabin. He was burning rubber toward Apatzingan, the town where he was born, after hearing his older brother had just been arrested in a federal raid. He never made it.

State police pulled the car over and took him into custody, ending a days-long manhunt for the second-in-command of a CJNG-linked micro-cartel that had terrorized the mountains around Morelia for four years.

Hours earlier, federal and state forces had raided a safe house and captured his brother, Ernesto Rafael "N," alias "El Sierra 1." The two brothers led the "Cartel de Altozano," a criminal cell named for the upscale Morelia neighborhood where it first took root but operating deep in the rugged sierra of Madero, Acuitzio del Canje, Tzitzio, and Morelia itself.

"El Sierra 1 was considered a priority target and one of the main generators of violence in Morelia," said Omar Garcia Harfuch, head of Mexico's Security and Civil Protection Secretariat (SSPC), announcing the arrest. It was not his first close call. Harfuch confirmed that "El Sierra 1" had evaded authorities on two previous occasions before the June 25 capture, when agents finally served an active arrest warrant backed by intelligence work. A woman was also detained during the raid, and authorities seized high-caliber weapons and drugs from the property.

The brothers are now charged as the intellectual authors of the murder of Sergio Rangel Vieyra, a respected mezcal producer killed on May 22, 2025, on the rural highway connecting the Morelia communities of San Miguel del Monte and Piedras de Lumbre. Rangel Vieyra had spent years building a name for himself distilling agave in the sierra, producing small-batch mezcal that found buyers across the state. He was the kind of small-business success story that extortion rackets feed on, and his death sent shockwaves through the tight-knit mezcalero community.

Rangel Vieyra was not the only victim. According to the Michoacan State Prosecutor's Office (FGE), the Sierra brothers ran a systematic extortion operation targeting wood merchants in the municipality of Madero and small-business owners in the Morelia communities of San Miguel del Monte, Jesus del Monte, El Capulin, and El Duende. The pattern was familiar: men with guns showing up at lumber yards and corner stores, demanding weekly payments, threatening fire if anyone refused.

"This cartel had carved out a territory in the mountains and was bleeding these communities dry," a law enforcement source familiar with the investigation told local media. "The wood merchants and mezcaleros were their ATM."

Alfredo "El Sierra 2" is identified by the FGE as the second-in-command of the Cartel de Altozano, a group linked to the Jalisco New Generation Cartel (CJNG), one of Mexico's most powerful and violent criminal organizations. The cell established itself in the mountainous periphery of Morelia roughly four years ago, slowly tightening its grip on the region's trade routes and small businesses.

His arrest on the highway unfolded like a scene from a crime novel. Police found the stolen vehicle, the military-grade rifle, ammunition, and a bag of methamphetamine. His romantic partner was also detained. Investigators believe he was scrambling to relocate to his hometown of Apatzingan, a CJNG stronghold in the Tierra Caliente region, after learning his brother had been taken into custody.

The double arrest represents a significant blow to CJNG's revenue streams in Michoacan's highlands. Extortion is a cash business, and the Sierra brothers had been collecting for years across multiple municipalities. But takedowns in Mexican organized crime rarely come without complications.

The vacuum left by the Sierra brothers' arrests could spark a power struggle within the Cartel de Altozano or invite rival groups to probe the territory. The mountains of eastern Michoacan have long been a contested zone, with CJNG, the Familia Michoacana, and smaller local cells jostling for control of extortion corridors, timber trafficking routes, and the agave trade. For now, the wood merchants and mezcaleros of Madero and Morelia have two fewer men to fear. But in Michoacan's criminal landscape, the silence never lasts long.
