Overview
- The attack on General Middle School No. 13 in the La Unión area of Torreón occurred during a class transition and left the vice principal dead and three others injured.
- Local residents and staff intervened to restrain the two 18-year-old brothers, both former students, and held them until police took them into custody.
- Authorities have ruled out gunfire and say witnesses and early probes indicate the assailants used bladed weapons and crude explosive devices such as Molotov-type or firecracker devices.
- State prosecutors have begun taking statements from the suspects and witnesses while stressing that a motive is unconfirmed though initial accounts point to a prior conflict with the school.
- The attack prompted students to be sheltered then evacuated and it has revived scrutiny of rare but high-profile school attacks in Mexico as investigators continue forensic work and interviews.
