Polemic billboards springing up around Colombia, sponsored by former vice president and potential 2014 presidential candidate, Francisco Santos, ask viewers to guess who killed more cops, deceased drug lord Pablo Escobar or FARC leader Ivan Marquez. One billboard in Medellín recently was bombarded with tomatoes by an angry group of citizens. Despite a pending order from the National Electoral Council to take the billboards down, Santos said he had no intention of doing so. "Don't come to me and say that we are using the pain of the victims," he said. "No, I know and I have worked with the victims," referring to his work for the Pais Libre foundation that defends the rights of kidnapping victims and their families.

The US Department of Justice on April 15 accused Guinea-Bissau's top military official, Gen. Antonio Indjai, of plotting a cocaine-for-weapons deal with Colombia's FARC rebels, according to court documents seen by Reuters.  The indictment, filed in district court in Manhattan, charges Indjai on four counts: "narco-terrorism conspiracy"; conspiracy to provide material support to a foreign terrorist organization; cocaine importation conspiracy; and conspiracy to acquire and transfer anti-aircraft missiles. The supposed deal came to light after Guinea-Bissau's former navy chief and six henchmen were arrested on the high seas by US forces.

Opium cultivation in Afghanistan is expected to increase for a third straight year, expanding even to new areas of the country, a UN report warned April 15. The Afghanistan Opium Risk Assessment 2013 found that the country is moving towards record levels of opium production this year despite eradication efforts by the international community and Afghan government. "The assessment suggests that poppy cultivation is not only expected to expand in areas where it already existed in 2012... but also in new areas or in areas where poppy cultivation was stopped," the survey found. The study by the UN Office of Drugs and Crime (UNODC) says insecurity and lack of agricultural assistance are fueling opium cultivation. "Villages with a low level of security and those which had not received agricultural assistance in the previous year were significantly more likely to grow poppy in 2013," the report said.

Six people were strangled to death and one decapitated in the Mexican tourist resort of Cancún April 14—the latest mass killing to strike the city in the last few weeks. Police found the bodies of the five men and two women in a shack in the outskirts of the Yucatan Peninsula city, which has largely escaped the drug-related violence that has rocked Acapulco, a faded tourist destination on the Pacific coast. Quintana Roo authorities said the vicitms were small-scale drug dealers. In a separate incident that day, police found the body of another man in Cancún who had been gagged, bound and wrapped in sheets. (AP, April 15) The slayings come one month after seven were killed when gunmen burst into Cancún's La Sirenita (Little Mermaid) bar, targeting members of the city's taxi-drivers who were holding a meeting there. Several Cancún taxi drivers had been arrested recently for selling drugs or participating in drug-related killings, authorities said. (AP, Univision, March 15)

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)

Citing frustration with mounting criminal violence, the National Congress of Honduras on April 16 moved to suspend prosecutor general Luis Alberto Rubí  and his assistant, replacing them with a temporary oversight committee. The five-member commission, made up of leaders of the country's political parties, will have 60 days to analyze why the prosecutor's office, the Fiscalía General de la República, has made little headway on numerous criminal cases, and draft a plan to reform the institution. With a homicide rate of 90 per 100,000 residents, Honduras is often called the world's most violent country. Prosecutors solve only about 20% of homicide cases, on average. The National Congress estimates 20,644 homicides have gone uninvestigated in the 28 months of the current administration.

The Brazilian state of Acre declared a state of "social emergency" April 10 in response to a surge of undocumented migrants from neighboring Bolivia and Peru—originating in countries from Haiti and the Dominican Republic to Bangladesh to Senegal and Nigeria. Officials said some 1,700 migrants had arrived during the past two weeks. The state "has been turned into an international travel route controlled by coyotes,"  said Nilson Moura, Acre's secretary for Justice and Human Rights., referring to the smugglers who guide the migrants into Brazil, often in exchange for exorbitant fees. The jungle town of Brasileia has become a key transport point for migrants bound for Sao Paulo and Rio de Janeiro. Brazilian police last year raided a number of sweatshops in Sao Paulo and the capital, Brasilia, where undocumented immigrants from Bolivia and Pakistan were found working in unsafe conditions for very little or no pay.

At least 15 were killed April 10 in a series of confrontations in Mexico's increasingly conflicted Michoacán state. The first confrontation began when federal police aboard a helicopter spotted armed men traveling in four vehicles at Charapando in the muncipality of Gabriel Zamora. The gunmen opened fire on the agents, who shot back and killed five, a police statement said, adding that one of those killed was high in the leadership structure of a local drug cartel, which was not named. Two police agents were reported wounded. Hours later in the town of Apatzingan, federal agents were accompanying a procession commemorating the anniversary of the death of Mexican revolutionary Emiliano Zapata when gunmen opened fire with AK-47s. Police returned fire, killing one. Another eight were killed elsewhere in Apatzingán, when gunmen attacked a police checkpoint where trucks full of harvested lime were backed up; two police were injured, but the dead were all civilians. Schools in Apatzingán and Buenavista Tomatlán municipalities have been closed due to the violence.
