Mexican naval forces on July 13 captured Miguel Angel Treviño Morales, head of the Zetas cartel, who was apprehended with two lieutenants in a pick-up truck in the municipality of Anáhuac, Nuevo León. Early reports that placed the arrest in Treviño's home turf of Nuevo Laredo, Tamaulipas, were apparently incorrect. Officials said he had eight guns and $2 million in cash. Treviño and his henchmen reportedly surrendered without firing a shot as a military helicopter began tailing their vehicle from their air. They are now said to be under interrogation by the Special Sub-prosecutor for Investigation of Organized Crime (SEIDO).

Guatemala's President Otto Pérez Molina said he is considering imposing a state of emergency in Salcajá, Quetzaltenango department, after an armed attack on a substation of the National Civil Police (PNC)  left eight officers dead and their commander abducted June 14. Authorities said the slain officers were disarmed, made to face down on the ground, and then shot in the head, execution-style. Pérez Molina attributed the attack to drug gangs operating in the area, with possible links to Mexican criminal networks such as the Sinaloa Cartel or Los Zetas. Jorge Santos of the International Center for Human Rights Research (CIDH), set up to secure political rights after Guatemala's civil war, said he hoped "this terror will not lead to greater levels of social control by the executive."

On June 4 Mexican army soldiers freed 165 people, mostly Central Americans, who the authorities said had been held for as much as three weeks by an unidentified criminal organization at a safe house in Las Fuentes, Gustavo Díaz Ordaz municipality, a few miles from the US border in the northeastern state of Tamaulipas. One person, apparently a lookout for the kidnappers, was arrested. The captives were reportedly migrants planning to cross illegally into the US; the smugglers ("polleros") they had hired may have turned them over to a criminal group, possibly the Gulf drug cartel or the Los Zetas gang.

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)

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.

Authorities in Mexico's coal-producing northern state of Coahuila say that the notorious Zetas, bloodiest of the country's warring cartels, have taken over much of mining industry. Suspicions were first raised in October when top Zeta commander Heriberto Lazcano was found in a Coahuila coal mining town and killed in a shoot-out with Mexican marines. Coahuila produces some 95% of Mexico's coal at approximately 15 million tons a year, and current estimates place the Zetas' annual profits from their share of the industry at around $25 million. Former Coahuila governor Humberto Moreira said the Zetas are expanding their control over the state's mines, both legal and illegal. "They discover a mine, extract the coal, sell it at $30, pay the miners a miserable salary," he told Al Jazeera. "It's more lucrative than selling drugs."

Two women are among the dead in a fierce gun battle that claimed five lives March 16 in Reynosa, Tamaulipas, just across the Mexican border from Hidalgo, Tex. Tamualipas state authorities said the women were among the combatants. The fire-fight came one day after Mexican federal police found more than five tons of marijuana, 370 pounds of crystal methamphetamine and a large weapons cache in underground bunkers in Reynosa—including 20 rifles, 10 bulletproof vests, a gas grenade, 20 uniforms, radios and tire spikes. March 11 also saw a three-hour gun battle in the streets of Reynosa, with rival narco-factions using automatic weapons and grenades. Authorities were absent for most of the shoot-out that left some three dozen gunmen and two bystanders dead—one just a teen. An exact death toll was elusive, as cartel gunmen collected their own dead during the battle.

A new report highlighting Mexico's human rights crisis finds that security forces have taken part in many kidnappings and disappearances over the six-year term of President Felipe Calderón, with the government failing to investigate most cases. Despite some controversy over the numbers, an estimated 70,000 are believed to have met violent deaths under Calderón's militarized crackdown on the cartels. But the new report, released by Human Rights Watch Feb. 20, finds that on top of this figure, possibly more than 20,000 disappeared during Calderón's term. Many were abducted by narco gangs, but all state security forces—the military, federal and local police—are also accused in "the most severe crisis of enforced disappearances in Latin America in decades."
