Family members of inmates are keeping vigil outside Palmasola prison in Santa Cruz, Bolivia, with signs demanding to know the whereabouts of their loved ones, after an explosion of violence at the facility left at least 30 dead Aug. 24. Authorities have still not released the names of the dead and wounded in the conflagration that began as a fight between rival gangs.  Most of the victims burned to death after inmates blew up two propane tanks and fashioned others into improvised flamethrowers. Some prisoners jumped from the roof to escape the flames. Among those killed was an 18-month-old infant, one of some 250 children living in the prison with their incarcerated parents. Inmates at two other Bolivian prisons—San Pedro in La Paz, and San Sebatián in Cochabamba—have declared their own "state of emergency" in solidarity with the Palmasola prisoners, and to demand a solution to the grave problems in the country's penal institutions.

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.

Colombia's campesinos, miners, truckers and other sectors launched a nationwide strike Aug. 19, with clashes reported as strikers launched roadblocks and President Juan Manuel Santos deployed elite National Police units. Central arteries were blocked in Boyacá, Nariño and Putumayo departments. In the town of Segovia, Antioquia, hundreds of protesters reportedly threw firebombs and tried to burn the police station, leaving six officers injured. Authorities say the strike has affected 12 of Colombia's 32 departments, but press accounts have put the number as high as 28.

The presumed kingpin of the Gulf Cartel, Mario Armando Ramírez Treviño AKA "El Pelón" (Baldy), who also went by the code-name X-20, was arrested by Mexican army troops along with two henchmen in Río Bravo, Tamaulipas, Aug. 17. Only one shot was fired in the apprehension. Spokesmen for the administration of President Enrique Peña-Nieto in announcing the capture predicted that it would put the breaks on the nightmarish violence in Tamaulipas between the Gulf Cartel and its rivals Los Zetas, and noted that several Gulf criminal operatives have been arrested this month. 

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. 

The area of land planted with coca leaf in Colombia has fallen by 25%, and is now about a third of that in 2001, according to the latest report from the UN Office on Drugs and Crime (UNODC)'s Integrated Illicit Crops Monitoring System. The report finds that land planted with coca has dropped from 64,000 hectares in 2011 to 48,000 hectares in 2012, the lowest figure since monitoring started in Colombia more than a decade ago. Although the National Police actually eradicated less coca than in previous years, the force increased its presence in coca-growing regions, apparently preventing campesinos from planting coca in the first place. But while coca areas fell nationwide, they rose in three departments still especially wracked by armed conflict—Norte de Santander, Chocó and Caquetá.

A court in Trujillo, Peru, issued a ruling July 23 absolving former National Police colonel Elidio Espinoza and nine troops who served under him in the deaths of four suspected "delinquents" in the coastal city in 2007. Espinoza, who was accused of operating a "death squad" within the National Police, had been sentenced to life in prison by the Public Ministry, the branch of Judicial Power with authority over government officials, for the crimes of kidnapping, homicide, and abuse of authority. After the ruling was issued, Espinoza led his supporters in a public celebration in Trujillo's Plaza de Armas. (Peru21, RPP, July 23)

The First Supra-provincial Court of Lima on July 30 issued an order of preventative detention against ex-lawmaker Nancy Obregón, on suspicion of narco-trafficking and "collaboration with terrorism." Obregón, who rose to prominence as a leader of peasant coca-growers, was taken into custody by troops of the National Anti-drug Directorate (DINANDRO), and turned over to judicial authorities for interrogation. Her case will then return to a judge who will decide whether she is to be held for the full 15 days permissible under Peruvian law.
