Here we go again. Mexican authorities announced March 9 the death of Michoacán's top drug lord Nazario Moreno AKA "El Chayo" in a shoot-out that erupted when a mixed force of military and federal police troops raided his 44th birthday party in the pueblo of Apatzingán. Also known as "El Más Loco" (the Craziest One), "El Macho Loco" and "El Doctor," Moreno was the founder of both La Familia cartel and its offshoot, the Knights Templar. But there is an all-too-familiar sense of deja vu here: this is the second time that El Chayo was reported killed in a shoot-out with federal cops in Apatzingán. The first time was in December 2010, although authorities didn't produce the body. This time they have, and boast positive forensic identification.

Mexican authorities on March 4 announced the seizure of 119,000 tons of iron ore—with an estimated value of $15.4 million—along with 124 bulldozers, backhoes and trucks at Michoacán's Pacific seaport of Lázaro Cardenas, following tips about drug cartels exporting black-market ore to China. More than 400 federal police and military troops were involved in the coordinated raids on 11 processing facilities in the port city. Six Chinese workers at the sites were arrested, apparently on immigration charges. The federal security commissioner for Michoacán, Alfredo Castillo, told Periódico Digital that the ore is being tested to determine which mines it came from in order to crack down on the operation. In November 2013, the Mexican Navy took control of Lázaro Cardenas to cut off illicit exports for the Knights Templar drug cartel. (Metal Miner, March 7; Mining.com, Port Technology, March 4)

Alma Delia Olivares Castro, an announcer on the La Cabina community radio station in Omealca municipality in the eastern Mexican state of Veracruz, was arrested on Feb. 28 and was held in a federal prison in Nayarit state for five days on charges of "auditory contamination." The authorities released Olivares Castro on March 4 after her family put up 25,000 pesos (about US$1,893) in bail, but she still faces criminal charges. After realizing that "auditory contamination" is not an offense under Mexican law, the authorities changed the charge to "undue use of a national good" (the airwaves). The station has already been closed and fined 29,000 pesos (about US$2,199) under the Federal Radio and Television Law, which regulates the licensing of radio and television stations.

Some 1,200 employees of the Mexican oil company Oceanografía SA de CV began blocking the four entrances to the Laguna Azul industrial dock in Ciudad del Carmen in the eastern state of Campeche early on the morning of March 7, disrupting the operations of at least 40 companies that provide services to Petróleos Mexicanos (Pemex), the government's giant oil monopoly. The workers were demanding payment of wages that have been held up since the government's Finance Secretariat took over the bankrupt company at the end of February after it became mired in allegations of fraud.

Authorities in the northeastern Mexican state of Coahuila announced Feb. 7 that they had recovered at least 500 sets of human remains from mass graves scattered across 11 municipalities—mostly in the north of the state, along the Texas border. Most of the remains were bones, which had largely survived apparent attempts at incineration. Several vats used to dissolve the remains in acid were also found in the graves. No group has been named as responsible for the killings, but Coahuila is a battle-ground in the ongoing war between the Zetas and their rivals in the Gulf and Sinaloa cartels. The Mexican media are calling the finds "narco-graves." The state Prosecutor General's office says it will take at least four months to ascertain the number of victims among the remains, much less identify them.

Mexican authorities on Feb. 22 announced the arrest of the country's top drug lord, the notorious Joaquin Guzmán Loera AKA "El Chapo" (Shorty)—who had eluded capture for over 10 years, despite a supposed manhunt and a massive price on his head. Chapo was detained in Mazatlán, Sinaloa, and immediately transfered by Federal Police helicopter accompanied by an escort of two Armed Forces helicopters to the top-security Federal Center for Social Rehabilitation No. 1 at Altiplano, México state. The prison has since been under escalated security measures, ringed by armed troops, with nearby highways patrolled by convoys of Federal Police vehicles. (La Jornada, Feb. 22)

Mexico's Network for Solidarity and Against Repression (RvsR) is calling for international support for the Zapatista base communities in Chiapas state following attacks late last month, urging, "If they touch the Zapatistas, they touch all of us." (UDW, Feb. 14; Enclace Zapatista, Feb. 13) The Zapatista Good Government Junta at the village of Morelia announced on Jan. 31 that several communities within its zone had been attacked by a "mob" of some 300 followers of the Independent Central of Agrarian Workers and Campesinos (CIAOC), who menaced residents with machetes and left three injured. (La Jornada, Feb. 1) The executive committee of CIAOC later disavowed the attacks, saying they had been carried out by the breakaway "CIAOC-Democratic" faction. (La Jornada, Feb. 15) Chiapas state police on Feb. 18 detained CIAOC leader Corazón Gómez Consuegra on charges related to factional violence within the organization in Tapilula municipality. (Es!DiarioPopular, Chiapas, Feb. 19)

Mexican security forces announced Jan. 30 the arrest of a top leader of the New Generation drug cartel, based in the western state of Jalisco. Rubén Oseguera González AKA "El Menchito" is said to be second-in-command in the criminal organization led by his father, Nemesio Oseguera Cervantes AKA "El Mencho," and is also known as "El Junior." He was arrested in a major operation that involved dozens of army troops in Zapopan, a city in the Guadalajara metropolitan area. There remains a 2 million peso ($150,000) price on the head of El Menchu, and media accounts said he narrowly escaped capture last year. The New Generation group is said to be allied with the Sinaloa Cartel, Mexico's most powerful trafficking organization.
