The confrontation with authorities took place along the Jalisco-Michaocan state border. A large group of forces belonging to Jose de Jesus Mendez, alias 'El Chango,' had gathered there for an assault on the Knights Templar, the newly minted gang of Servando Gomez, alias 'La Tuta,' the authorities said.
This came after a May 24 attack on a government helicopter in Apatzingan, where authorities say Gomez's group has its stronghold. Another helicopter crashed in the area on May 28, which authorities attributed to mechanical difficulties.
The two groups are fighting for control of a lucrative methamphetamine corridor."
