Overview
- The attack took place Thursday morning during a class change at Escuela Secundaria General No. 13 in ejido La Unión and left subdirectora Nery Edith Narváez González dead and three people wounded, including at least one student in serious condition.
- Authorities detained two 18‑year‑old brothers who are former students of the school and placed them at the disposal of the ministerial authority for questioning and prosecution.
- Preliminary pericial work by the state Fiscalía indicates the use of bladed weapons and petard‑type devices, and officials say initial reports of gunfire came from detonations that are still being forensically examined.
- Neighbors, school staff, and students intervened at the scene, subdued the attackers and handed them to police before formal arrest procedures, and victims were evacuated to local hospitals for treatment.
- Federal security bodies and the SEP have offered coordination and institutional support as the Fiscalía continues scene processing, evidence collection and interviews, and the attack has raised fresh scrutiny of school safety in Torreón after prior episodes of violence.
