Joaquín "El Chapo" Guzmán, infamous kingpin of Mexico's Sinaloa Cartel, was unanimously found guilty on all 10 counts against him by a federal jury in Brooklyn, New York, on Feb. 12. He was convicted of overseeing an international criminal conspiracy to import tons of cocaine, heroin, methamphetamine and marijuana into the United States over a 20-year period, and laundering the billions of dollars in proceeds.

The latest grim manifestation of the unrelenting prison crisis in Latin America comes from the northern Mexican state of Nuevo León, where authorities confirmed Oct. 10 that 16 inmates were killed, and 25 wounded, in an uprising at the Penal de Cadereyta facility. Prison riots in Mexico are often related to struggles between rival narco-gangs, but this one started as an inmate protest over abysmal conditions at the overcrowded state lock-up. Prisoners took guards hostage to press such basic demands as adequate food and water. One prisoner was killed in fighting with guards before the state police were sent in. The inmates erected barricades of matresses and set them on fire, prompting police to respond with lethal force.

Yet another Mexican journalist was slain Aug. 22, as the cartels continue to exact vengeance on any who would dare to report on their reign of terror and corruption across much of the country. Cándido "Papuche" Ríos, who covered the nota roja (crime and police beat) for local newspaper Diario de Acayucan, was gunned down by unknown assailants along with two other men in the town of Hueyapan de Ocampo, Veracruz state. One of the other two men, with whom Ríos was talking outside a gas station, was a former municipal official.

Mexico's northeastern border state of Tamaulipas—just across from Texas' Gulf Coast—has for years been engulfed in an under-reported war, as the Gulf Cartel and its rogue offspring the Zetas battle for dominance over the narco-trafficking "plaza" (zone of control). The current flare-up in the border town of Reynosa may signal a turning point. Street gun-battles have become so common in the town that authorities have instituted a color-coded alert system to warn citizens. The town has been on "red alert" repeatedly over the past days, and there are signs that the long struggle is entering an endgame.

The Zapatista rebels in Mexico's southern state of Chiapas marked the anniversary of their 1994 New Years Day uprising by hosting a national activist gathering in their territory. Guests of honor at the proceedings in the small pueblo of Oventic were a group of parents and other family members of the 43 students who disappeared in September 2014. The students, from Ayotzinapa in Guerrero state, are said to have been abducted by corrupt local police and turned over to a murderous narco-gang—but surviving kin and their supporters increasingly charge Mexico's government with a cover-up in the case. The Zapatistas' Subcommander Moises, joined by 43 masked rebels (one for each missing student), oversaw the ceremony and each embraced the family members. Moises expressed his own skepticism of the official investigation: "The Zapatistas believe that we cannot trust the bad governments anymore, they are the servants of capital, stewards of big capitalist business," he said. "The one calling the shots is global capitalism, that is why we cannot believe them." (TeleSur, Jan. 1)

Maya indigenous peasants in Mexico's southern state of Chiapas are marching cross-country to oppose violence by the local narco gangs and the corruption of local authorities that protect them. The "pilgrimage" left the rural town of Simojovel some 15,000 strong at the end of March, and is now arriving at the state capital Tuxtla Gutiérrez, some 240 kilometers away through rugged country. The pilgrimage was organized by the Catholic pacifist group Pueblo Creyente (Faithful People) with the support of the local diocese of San Cristóbal de Las Casas in response to a wave of narco-violence in Simojovel.

Mexican authorities on March 4 announced the capture of Omar Treviño AKA "Z-42"—leader of Los Zetas, the ultra-violent narco-paramilitary network that has long terrorized the country. Z-42 was detained without a shot being fired by federal police and soldiers in San Pedro Garza García, an upscale suburb of northern industrial hub Monterrey, officials said. US DEA chief Michele Leonhart congratulated Mexico, saying the bust "strikes at the heart of the leadership structure of the Zetas." The US State Department had a $5 million price on Treviño's head, while Mexican authorities offered $2 million.

Mexican authorities on Oct. 1 claimed another coup against the cartels, announcing the arrest of Héctor Beltran Leyva, last remaining kingpin of the Beltran Leyva Organization—the declining crime machine that once controlled much of the west and central parts of the country. Beltran Leyva was taken into custody by army troops "without a shot fired" as he dined in a seafood restaurant in the tourist town of San Miguel de Allende, Guanajuato state. (LAT, Oct. 1) The capture follows that earlier this year of the Sinaloa Cartel's long-fugitive jefe máximo Joaquin Guzmán Loera AKA "El Chapo"—marking another score for President Enrique Peña Nieto, and his supposed new and more sophisticated policy against the cartels.
