Nearly half a million were left without electricity for 15 hours after 18 substations were blown up Oct. 27 in a wave of coordinated attacks across Mexico's west-central state of Michoacán, the latest battleground in the country's relentless cartel wars. Six gasoline stations were also burned down near the state capital Morelia, in what authorities said was a terror campaign by the Knights Templar cartel. Gov. Fausto Vallejo Figueroa of the ruling Institutional Revolutionary Party (PRI) said the violence was set off by the Jalisco Cartel, based in the neighboring state of that name, seeking to "seize territory" controlled by the Knights Templars in Michoacán, and warned of a "great massacre" (matazón).

A new riot between rival gangs in the dangerously overcrowded prison at  Altamira, in the Mexican border state Tamaulipas, left seven inmates dead Oct. 26.  State authorities said the prisoners were killed with makeshift knives in a fight in one cellblock at the facility, officially known as the Execution and Sanction Center (CEDES). Thirty-one inmates died in a riot in the same prison early last year, pointing to a crisis rooted in the confluence of teeming lock-ups and the bloody narco wars being waged in Tamaulipas both inside and outside the prisons. The state is currently Mexico's most violent. The CEDES was designed to hold 2,000 inmates, but now has a population of more than 3,000. (AP, Notimex, Oct. 26)

US officials were secretly critical of the militarized anti-narcotic policies of former Mexican president Felipe Calderón Hinojosa (2006-2012) at the same time that the US government was funding and publicly backing them, according to declassified documents that the Washington, DC-based research group National Security Archive posted on its website on Nov. 6. The documents are among 30 official reports and diplomatic cables, with dates from Aug. 25, 2007 to May 22, 2012, that the US government released as a result of a Freedom of Information Act (FOIA) request from the National Security Archive and other organizations in Mexico and the US.

Alberto Patishtán Gómez, a schoolteacher from the southeastern Mexican state of Chiapas, was freed from imprisonment on Oct. 31 after receiving a pardon that day from President Enrique Peña Nieto. Patishtán had been serving a 60-year sentence since 2000 for his alleged involvement in the killing of seven police agents in Chiapas' El Bosque municipality in June of that year. He has consistently maintained his innocence. Human rights activists in Mexico and around the world demonstrated and petitioned for his release, charging that the teacher was being persecuted as an indigenous Tzotzil activist and a supporter of the leftist Zapatista National Liberation Army (EZLN).

In very disturbing news from Mexico's northeast border state of Tamaulipas, police on Oct. 1 said they rescued 73 abducted migrants outside Reynosa after following their apparent captors to a house and hearing frantic calls for help. Of the victims, 37 were Mexicans, 19 were from Honduras, 14 from Guatemala and another three from El Salvador. They included women and minors, some of whom reported having been sexually abused. Three suspects were detained, who are believed to have seized the migrants on buses they stopped in the desert. Some of the victims had been held for up to four months while their captors demanded payment from their families, police said. Weapons and drugs were also seized at the home, including nearly 700 rounds of bullets, a hand grenade, and almost 10,000 kilograms (22,046 pounds) of what was "believed to be" marijuana.

According to Mexican health authorities, 171 cases of cholera had been confirmed as of Oct. 18 in Mexico City and states north and east of the capital; one person had died from the disease. The outbreak, first identified on Sept. 9, apparently involves the South Asian strain of the cholera bacterium responsible for an epidemic that started in Haiti in October 2010. Scientific studies indicate that poor sanitary conditions at a United Nations Stabilization Mission in Haiti (MINUSTAH) base used by Nepalese troops caused the outbreak in Haiti, infecting at least 682,573 people as of Oct. 10 this year and causing 8,330 deaths and almost 380,000 hospitalizations.

Renowned Mexican investigative journalist Anabel Hernández, author of Narcoland: The Mexican Drug Lords and Their Godfathers, has been receiving police protection since her reportage outed top figures in the country's security apparatus as drug cartel collaborators—resulting in threats on her life. On Sept. 26 she spoke at an event hosted by New York University in Lower Manhattan, entitled "Too Dangerous for Words: Life & Death Reporting the Mexican Drug Wars." She spoke about her journey, and how she views the state of Mexico's narco-wars following last year's change of government.

Mexican federal police on Oct. 4 announced the apprehension of a fugitive Gulf Cartel operative, Eduardo Francisco Villatoro Cano AKA "Guayo"—wanted in Guatemala for a bloody attack on police earlier this year. Guayo was captured in Tuxtla Gutiérrez, capital of southern Chiapas state, bordering Guatemala. Guatemalan authorities hold him responsible for a June armed attack on a National Civil Police post in Salcajá, Quetzaltenango, in which nine officers were killed.  He was arrested along with his cousin, Édgar Waldiny Herrera Villatoro AKA "El Gualas." Although both men are Guatemalan nationals, they were said to be serving as agents of Mexico's Gulf Cartel. They were turned over to authorities in Guatemala, where President Otto Perez Molina said the Gulf Cartel network in the country has now been dismantled.
