Ángel Aguirre, former governor of Guerrero state in southern Mexico, has been formally charged with forced disappearance and obstruction of justice over his alleged role in the 2014 abduction of 43 student teachers from the Ayotzinapa rural college — a case that became a defining symbol of cartel violence and state impunity in Mexico. A judge ruled this week that prosecutors had presented sufficient evidence to proceed to trial, and ordered Aguirre held in a maximum-security prison; he is accused of ordering the destruction of surveillance footage that could have revealed what happened on the night the students vanished. The remains of only three of the 43 students have ever been identified, and a decade-long investigation found that local criminal gangs, municipal police, and federal security forces were all involved in the attack, while the government of the time orchestrated a cover-up including tortured confessions and tampered evidence.
