The Fiscalía, Colombia's public prosecutor, on Dec. 9 formally charged a notorious drug kingpin for masterminding several massacres between 1988 and 1994 in which hundreds of people were killed. The crimes, dubbed the Massacre of Trujillo after the town where they were committed in Valle del Cauca department, resulted in the deaths of up to 342 people. Among the victims were unionists, alleged guerrilla supporters, and a priest. Some of the victims were tortured and dismembered as a warning to rebel groups FARC and ELN, and their sympathizers. Diego Montoya AKA "Don Diego" is accused of conspiring with members of the army, police, regional politicians and paramilitary groups aligned to the infamous Cali Cartel. Several members of the security forces have also been charged for their alleged role in the killings.

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)

The latest Afghanistan Opium Survey (PDF), released Nov. 13 by the UN Office on Drugs and Crime (UNODC), finds that the country produced record levels of poppy in 2013. Total production reached 5,500 tons—up by nearly 50% over last year's figure of 3,700. Cultivation amounted to 209,000 hectares (516,000 acres)—a 36% increase over last year. The previous record was 193,000 hectares (477,000 acres) in 2007. And prices dropped by 12%—clearly due to boosted production. Eradication efforts fell by 24%, and the seizure rate lagged behind that of other opium-producing countries.

Two gunmen described as sicarios (hired assassins) killed Juan Álvaro Pai, a traditional governor of the Awá indigenous people, in an incursion into the resguardo (reserve) Inda Guacaray, in Colombia's southern Nariño department, Nov. 30. The gunmen arrived in the resguardo on a motorcycle, immediately made for Pai's home, and upon finding him fired six bullets into his body. Víctor Gallo, mayor of local Tumaco municipality, demanded that the Fiscalía (public prosecutor) and National Police open an urgent investigation, protesting the atmosphere of "impunity" that allows aggression against the Awá. In early July, Awá held a public demonstration, blocking the Pan-American Highway for a week, to protest the violence directed against their communities by various armed actors in Colombia's civil war. 

Three gun-battles in one day left at least 13 dead in the Mexican border city of Matamoros Nov. 2, Tamaulipas state authorities acknowledged. A statement from the Tamaulipas Coordination Group—the liaison office between state and federal forces—said two of the shoot-outs were between Mexican Marines and "armed civilians," the standard euphemism for cartel gunmen. One woman was among the 13 dead, who were also identified as "civilians"—leaving it unclear if they were combatants or by-standers. What press accounts called "narco-blockades" cut off traffic on the city's principal avenues. (Global Post, Crónica de Hoy, Nov. 4; Proceso, Nov. 3) Nov. 11 saw another outburst in the neighboring border city of Reynosa, with federal forces and presumed cartel gunmen having a high-speed shoot-out in a car chase through several neighborhoods. Allegedly, only one of the gunmen was killed, but video footage provided by the Facebook-coordinated network Valor por Tamaulipas showed a car overturned in road pile-up.

Mexico is shocked by the murder of Mayor Ygnacio López Mendoza of Santa Ana Maya, Michoacán, who was found dead in his car in neighboring Guanajuato state Nov. 7.  Just last month, he made national news when he held a public hunger strike outside the Senate building in Mexico City for 18 days—demanding more money for his town because of the 10% cut being extorted by the Knights Templar narco gang on all municipal spending. Authorities initially said the death was a traffic accident, but this claim evaporated when the autopsy report indicated "asphyxia secondary to neck trauma"—suggesting strangulation. Pressed for details by the Association of Local Authorities of Mexico (AALMAC), the Guanajuato Prosecutor General's Office, which had conducted the autopsy, admitted that López Mendoza had been tortured before being killed. During his hunger strike, López told Global Post that he knew he could be killed at any time. "We are on the knife's edge," he said. "I can be talking with you here today and in a few weeks you could be reading my death notice."

On Oct. 23, National Police in Peru apprehended in Lima an accused commander of one of the two surviving remnant factions of the Sendero Luminoso guerilla movement. The Interior Ministry named the detained man as Rolando Pantoja Quispe, and said he was under the orders of Florindo Eleuterio Flores Hala AKA "Comrade Artemio"—the notorious Sendero commander who was captured last year and condemned to life in prison. The ministry said Pantoja Quispe controlled cocaine trafficking in the Yanajanca Valley of Huanuco region, and hailed the arrest as a further blow against Artemio's crippled network.

On Oct. 19, a patrol of Bolivia's Joint Task Force, coordinating National Police and army troops in coca-eradication missions, was ambushed by unknown gunmen at  Miraflores pueblo, Apolo municipality, in the coca-growing Yungas region, sparking a gun-battle that left four dead—three troops and a medic. Up to 30 were injured, but all the assailants seem to have escaped. Government vice-minister Jorge Pérez said the attack was "planned by people related to the narco-traffic," adding that the partially buried remains of a cocaine lab had been found nearby. Days later, Leopoldo Ramos, the public prosecutor appointed to investigate the case, said that "by the form of execution, for the Public Ministry it is probable that those who attacked in Miraflores are persons trained by Sendero Luminoso."
