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.

A new massacre is reported from Ciudad Juárez, again raising fears of a return to the wave of deadly gangland violence that convulsed the Mexican border city for much of the past decade. Eight members of a single family—including two four-year-old girls and a six-year-old boy—were killed in their home Nov. 17 in the colonia (neighborhood) of Morelos Zaragoza. The bodies of the children were found on their beds, with multiple stab wounds, as were those of two young women. The two men were on armchairs, handcuffed and gagged. A two-month-old baby, known to have lived in the house, was not found among the dead. The family had been planning an event for their Jehova's Witnesses congregation when the attack took place. (Pulso, IOL, Proceso, Nov. 17)

Renowned Mexican investigative journalist Anabel Hernández, author of Narcoland: The Mexican Drug Lords and Their Godfathers, has been receiving police protection since her reportage outed top figures in the country's security apparatus as drug cartel collaborators—resulting in threats on her life. On Sept. 26 she spoke at an event hosted by New York University in Lower Manhattan, entitled "Too Dangerous for Words: Life & Death Reporting the Mexican Drug Wars." She spoke about her journey, and how she views the state of Mexico's narco-wars following last year's change of government.

Three men allegedly linked to Mexico's Sinaloa Cartel, accused of conspiring to distribute a thousand kilograms of cocaine in the US and Europe, face trial in a federal court in Concord, New Hampshire, after being extradited from Spain. According to network Univisión, the accused were apprehended in the Spanish port of Algeciras in August 2012. One defendant, Manuel Jesús Gutiérrez Guzmán, has been identified as a cousin of Joaquin Guzman AKA "El Chapo"—the Sinaloa Cartel's notorious fugitive kingpin. Another, Rafael Humberto Celaya Valenzuela, was a candidate for public office in San Luis Río Colorado, Sonora, with Mexico's ruling Institutional Revolutionary Party (PRI).

Sandra Ávila Beltrán, dubbed the "Queen of the Pacific" by the Mexican media, arrived Aug. 21 at the Federal Social Readaptation Center (CEFERESO) Number 4 in Tepic, Nayarit, days after she was extradited to Mexico from the US. The transfer came after a US judge in Maimi gave her credit for time served on the basis of five years she spent behind bars in Mexico and another year awaiting sentencing in Florida. She was arrested upon her arrival back in Mexico, to face new charges of money-laundering on behalf of the Sinaloa Cartel.

Mexico's most notorious kingpin, Rafael Caro Quintero, was released Aug. 9 from Puente Grande federal prison in Jalisco where he had been incarcerated for the past 28 years. He left the facility at dawn, several hours before the release order was made public. The First Appellate Tribunal in Guadalajara found in March that Caro Quintero was improperly tried for the 1985 torture-killing of DEA agent Enrique "Kiki" Camarena, and that charges should have been brought at the state rather than federal level. Federal prosecutors immediately appealed to the Supreme Justice Court of the Nation, which refused to rescind the lower court's decision. The Third Circuit Tribunal, also in Guadalajara, has now followed through by issuing Caro Quintero an amparo—a judicial order barring any federal action against him. 

President Barack Obama said April 30 he will wait until he meets with his Mexican counterpart Enrique Peña Nieto this week to discuss Mexico's decision to curtail access of US security agencies. "I'm not going to yet judge how this will alter the relationship between the United States and Mexico until I've heard directly from them to see what exactly are they trying to accomplish," Obama said in Washington. Mexico confirmed days earlier that it has ended direct access by US law enforcement agents to their Mexican counterparts; now all communication is to be routed through the federal interior ministry, Gobernación.

Colombian National Police on April 17 announced the arrest in Cali of Cesar Demar Vernaza AKA "El Empresario"—accused boss of Ecuadoran narco-gang Los Templados and purported top South American operative of Mexico's Sinaloa Cartel. In February, he had escaped from a maximum-security prison in Guayaquil, known as "La Roca" or "The Rock," where he was serving a 25-year sentence for homicide. He allegedly came to Cali to establish contact with regional narco bosses and rebuild his operations along Colombia's Pacific coast. Arrested with him was an associate named only as "La Bestia" (the Beast) who was also among the 16 convicts sprung from La Roca in the February jailbreak. La Bestia attempted to resist arrest, taking the residents in his building hostage and threatening to blow up a gas tank. Authorities negotiated him down and he ultimately surrendered. (Colombia Reports, April 17)
