Overview
- The attack began at the suspect’s home and continued at Debsirin Nonthaburi School on Friday, Aug. 7, 2026, when a 14-year-old student shot his grandparents before opening fire at the campus and later dying of a self-inflicted wound.
- Authorities say the shooter fired at least 26 rounds, was found with dozens more, and investigators recovered a handgun that officials say had been registered to his grandfather.
- Police seized computers and electronic devices from the home, interviewed classmates and teachers, and are probing online searches and reported academic stress as possible motives.
- National leaders have pledged tighter limits on who may carry firearms, ordered school security reviews, deployed mental-health teams and announced financial aid for victims, including cash payments to bereaved families and the injured.
- The attack has reignited debate over gun access and enforcement in Thailand, which has high civilian gun ownership and a recent history of mass shootings, and investigators have said further updates will follow a planned press briefing.
