Fifty-four criminal dossiers remain unresolved 55 years after the 1971 "Halconazo" massacre in Mexico City [1], [2].

The lack of prosecution for the attack on student protesters highlights a long-standing pattern of state-sponsored impunity in Mexico. For victims and their families, the failure to close these cases represents a systemic refusal by the state to acknowledge past human rights abuses.

The massacre occurred on June 10, 1971 [3]. Since then, the responsibility for delivering justice has passed through several administrations, including the Institutional Revolutionary Party (PRI), the National Action Party (PAN), and the current government [1]. Activists said that these successive administrations have prioritized political interests over the legal resolution of the crimes [1].

Félix Hernández Gamundi, a human-rights activist, has been vocal about the government's failure to act. He said that governments have managed time instead of delivering justice [1].

According to available records, 54 criminal cases are still open [2]. This legal stalemate means that the perpetrators of the 1971 violence have never faced full accountability in a court of law. The persistence of these open files suggests that the legal machinery has been intentionally stalled, a move activists describe as a method of maintaining impunity [1].

The Halconazo remains one of the most significant traumas of Mexico's 20th-century political history. The event involved a violent crackdown on student demonstrators, yet the official narrative and legal outcomes have remained stagnant for over five decades [1].

54 criminal dossiers remain unresolved

The continued impunity surrounding the Halconazo massacre demonstrates the difficulty of achieving transitional justice in Mexico. By leaving 54 dossiers open without resolution, the state maintains a legal limbo that prevents both finality for victims and the establishment of a definitive historical record of state violence.
