Grieving families gathered at Bangkok’s Institute of Forensic Medicine to claim the bodies of loved ones killed during a deadly Thailand school shooting. The tragedy unfolded on Friday, August 7, 2026, when a 14-year-old student opened fire at Debsirin Nonthaburi School in Bang Kruai district after fatally shooting his grandparents at their home. The rampage resulted in nine total deaths—including the perpetrator and eight victims—and left more than 20 people injured, making it the nation’s deadliest mass shooting since the 2022 Nong Bua Lamphu massacre.

Details of the Attack and Ongoing Motive Investigation

Investigators revealed that the 14-year-old suspect used his grandfather’s 9mm CZ-75 Compact semi-automatic pistol to shoot his grandparents at dawn before traveling to his high school. Upon arriving at the campus northwest of Bangkok, the shooter discharged 26 rounds along third-floor corridors, targeting teachers, administrators, and students before taking his own life. On Saturday, August 8, a 12-year-old female student succumbed to critical wounds at a local hospital, bringing the victim death toll to eight.

Police examining the suspect’s computer noted that he had recently watched videos of American mass shootings. Furthermore, classmates reported that the teenager had experienced severe academic stress and was a frequent target of school bullying.

“Everyone was saddened and shocked, because it was unexpected that this would happen in Thailand, and also it’s quite a great loss.”

National Response and Demands for Firearms Reform

In response to the tragic violence, Thai Prime Minister Anutin Charnvirakul pledged to introduce strict new firearms control legislation. Although Thailand maintains one of Southeast Asia’s highest civilian gun ownership rates—with approximately 10 million firearms in circulation—the proposed law would restrict carrying guns in public strictly to active-duty government officials. Meanwhile, administrators at Debsirin Nonthaburi School suspended all classes and directed staff to work remotely while grief counselors support traumatized students and families.
