Hours after drug lord Nemesio Rubén Oseguera Cervantes, also known as El Mencho, was killed, massive chaos broke out in several Mexican states. Air Canada suspended its operation to Mexico's Puerto Vallarta, the seaside city of Jalisco state where El Mencho was killed. El Mencho was wanted by the US but there was initially no information on whether FBI was part of the operation that gunned down El Mencho. Mexican news sites said El Mencho was killed by the military though the operation only intended to capture El Mencho. Later, the Mexican Secretariat of National Defense confirmed that in addition to the central military intelligence efforts, within the framework of bilateral coordination and cooperation with the USA, complementary information was provided by US authorities.
Reports claimed that a gunfight started when the military went to capture El Mencho, resulting in his death. In response to El Mencho's killing, his CJNG cartel, the biggest in Mexico, initiated widespread blockades across six Mexican states. The Mexican authorities declared 'code red' mobilization as at least 15 cities reported cartel-linked unrest.
