Overview
- The attack occurred inside Escuela Secundaria General No. 13 and left the subdirector, Nery Edith Narváez González, dead according to the Fiscalía.
- Authorities say the suspects are two 18‑year‑old brothers who are former students of the school and are now in custody and at the disposal of ministerial investigators.
- Preliminary peritajes by the Fiscalía indicate the assailants used knives or machetes and objects like petards that caused detonations, and officials have not confirmed the use of firearms or large explosives.
- Teachers, students and neighbors reportedly subdued the suspects at the scene and handed them to police before emergency services treated the wounded and authorities sealed the school for evidence collection.
- Federal and state agencies have pledged institutional and psychosocial support to the school and are coordinating the criminal investigation while authorities probe motive and any links to online material that investigators say the suspects followed.
