Mexican security forces arrested former municipal police officer Rey Flores Hernández this week for his alleged participation in the mass kidnapping and disappearance of 43 students from Ayotzinapa in 2014. The students were attacked by local police before being hauled off and murdered by the Guerreros Unidos.
The Guerreros Unidos are an important player in the production and trafficking of heroin, according to US authorities, and have been behind several episodes of exceptional violence in Mexico. The Ayotzinapa kidnapping exposed the group’s deep control over corrupt state authorities, including public officials, the police, and the military.
