Corpus Christi (Halconazo) Massacre — New Bloodshed Under Echeverría

On June 10, 1971 (Corpus Christi Day), a student demonstration in Mexico City is attacked by the Halcones (Falcons), a paramilitary group assembled under Echeverría's watch. Approximately 120 students are killed or disappeared. The attack occurs under Echeverría's presidency, demonstrating that 1968-style repression continued. The Halconazo becomes a companion atrocity to Tlatelolco in the history of PRI-era political violence.
