Gunmen shot and killed Jesús Manuel Lara Rodríguez, mayor of the Mexican border town of Guadalupe as his wife and child watched on June 19. Lara Rodríguez was hit by 10 bullets from an assault rifle as he walked from his car outside his second home in Ciudad Juárez. An outspoken opponent of the drug cartels' reign of terror in the region, Lara had received numerous death threats. He had recently purchased the home in Juárez, the closest city to Guadalupe, believing his family would be safer there. (CNN, El Dairio, Juárez, June 20)

After three days of searching, Mexican army troops and Quintana Roo state police on June 18 discovered 12 bodies in four cenotes (natural wells) near the Cancún airport. Last week, six bodies were found in another presumed narcofosa (narco-grave) in Cancún. Authorities were apparently tipped off to mass graves by arrested sicarios (assassins), and 19 more have been arrested in their connection. Among those detained are a former member of the Kaibiles, the Guatemalan army's special forces, and an ex-agent of the Cancún municipal police. Authorities did not say which faction the detained belong to, but press accounts have identified them as members of Los Zetas. (El Universal, AFP, June 18; Diario de Quintana Roo, June 17)

More than 200 people have been killed over the past seven days in Mexico's most violent week since President Felipe Calderón unleashed federal forces against the country's warring drug cartels. In the latest slayings, on June 16 Nuevo León state investigators in the Monterrey suburb of Apodaca recovered the bodies of five municipal police officers who had been abducted at dawn from their homes by armed men. Their bodies, with signs of torture, were found in an abandoned plot of land with a threatening "narco-message." One had been decapitated. Dozens of police have been killed in the Monterrey area in recent months. Authorities also said an armed commando executed three local youths in the Monterrey barrio of Primero de Mayo.

Violence in Mexico claimed the lives of 15 federal police officers and 29 prison inmates in three separate incidents June 14.

At Aguaruto prison in Culiacán, Sinaloa, 21 inmates were shot to death and three guards were wounded when a group of prisoners attacked members of a rival gang within the facility. Hours later, eight more prisoners were stabbed to death by other inmates. An AK-47 assault rifle and two large-caliber handguns were confiscated. (CNN, AP, LAHT, June 15)

Bill Conroy writes for the Narcosphere, June 12:

A special operations task force under the command of the Pentagon is currently in place south of the border providing advice and training to the Mexican Army in gathering intelligence, infiltrating and, as needed, taking direct action against narco-trafficking organizations, claims a former CIA asset who has a long history in the covert operations theater.

Narco-violence claimed 39 lives in two northern Mexico states June 11. In Chihuahua, up to 30 gunmen stormed a drug rehabilitation center in the state capital Chihuahua City near midnight and executed 19 men and wounded four others. The victims, all reportedly addicts being treated by the clinic, were forced to lie face down in a hallway and were then shot, witnesses told local media. Rehab centers are reportedly being used as fronts by drug gangs who recruit "mules" among the recovering addicts, and have been a target in the warfare between rival cartels. One day earlier, unidentified assailants killed one man and wounded another at a rehab center in Ciudad Juárez. More than 60 people have died in mass shootings at Mexican rehab clinics in a little less than two years.

Mexican and US authorities are investigating the death of a 14-year-old boy who was shot late June 7 near the Juárez-El Paso crossing, apparently by a US Border Patrol agent. Eyewitnesses said Sergio Hernández was playing with friends in a dry area of the river that forms the border. Crossing momentarily into the US with his friends, he was chased by a patrol agent. He ran back onto Mexican soil, hid behind a steel wall—and was shot in the head when looked out.

As many as 2,000 Mexican federal police and Sonora state police, supported by helicopters, invaded the Cananea copper mine on the night of June 6, firing tear gas and attacking and beating workers who were defending the mine. With the police having cleared the mine, managers from Grupo Mexico, the mine owner, took control of the facilities. The company reported that it had 2,000 "contractors" ready to go to work as soon as it was safe to do so.
