A 14-year-old student is accused of shooting three teachers and three classmates to death inside a secondary school on the outskirts of Bangkok on Friday, hours after allegedly killing his own grandparents at the home they shared. By Friday afternoon, Thailand's prime minister had confirmed the teenager turned the gun on himself, closing out what authorities are calling the country's deadliest school shooting in years.
A Killing at Home, Hours Before the Bell
Police say the violence started long before the teenager reached campus. According to a national police statement carried by AFP, the student shot and killed his paternal grandparents — a 73-year-old man and 74-year-old woman — inside their home in Bang Bua Thong district, using a 9mm handgun that belonged to his grandfather. Investigators have not said how he obtained the weapon or whether it was stored securely. From there, he traveled to Debsirin Nonthaburi School, a co-ed secondary campus of roughly 3,100 students and 147 teachers in the Bang Kruai district of Nonthaburi province, and opened fire during regular class hours.
Panic and Evacuation on Campus
The gunman fired at least 26 rounds and was later found carrying 34 more. Students barricaded themselves in classrooms as gunfire echoed through the building; one 18-year-old told Reuters he initially mistook the sound for firecrackers before it "started getting more frequent, like 'bang, bang, bang.'" A classmate, 17-year-old Purin Khumchoo, said he'd sensed something was wrong about the shooter even before Friday, telling AFP that when the gunman aimed at him, "he looked very professional, as if he had been trained." Traffic near the school ground came to a halt as panicked parents converged on the campus, and counselors were dispatched within hours to work with shaken students and staff.
The Toll: What's Confirmed, What's Still Moving
Casualty figures kept climbing repeatedly through the day. Police spokesperson Lt. Gen. Trairong Phiwphan said three teachers and three students were killed on campus, a toll confirmed separately by national police. Combined with the two grandparents, that puts the overall death count at eight — not including the shooter's own death by suicide. More than 20 people were wounded, with nine in critical condition, though the prime minister himself cited a total closer to 30 in one press appearance. The youngest confirmed victim was just 12 years old, with most of the wounded and killed described as teenagers between 12 and 17.
A Shooter's Background Still Largely Unknown
Officials have not released the suspect's name or established a motive. Classmates who spoke to AFP described him as fascinated by firearms and by the FBI, and said he had been bullied by other students. Bangkok Post identified him as a Mathayom 2 — roughly eighth-grade — student, though earlier wire reports had described him as a grade level higher, a detail that shifted as more official information emerged. No note, message, or manifesto has been reported at either scene, and police say it remains unclear whether the killing of his grandparents and the school attack were driven by a single triggering event.
Thailand's Recurring Nightmare
Friday's attack extends a pattern that has unsettled Thai schools and public spaces for years. In February, a gunman who had stolen a firearm from police attacked a school in Songkhla province in the country's south; the school's director later died of her injuries. In 2023, a 14-year-old opened fire inside Bangkok's Siam Paragon mall, killing two people. And Friday's shooting is now being described as the nation's worst since a former police sergeant killed dozens of people, most of them children, at a daycare center in Nong Bua Lamphu province in October 2022.
Gun Debate Reignites, Again
Thailand maintains comparatively strict firearms laws, yet ownership remains widespread: Thai civilians hold an estimated 10.3 million firearms, or roughly 15 per 100 residents — far below the more than 120 per 100 in the United States, but among the highest rates in Southeast Asia. Prime Minister and Interior Minister Anutin Charnvirakul, who froze new gun licenses for a year after the 2023 mall shooting, called Friday's attack "horrible" and said simply, "This is horrible, it shouldn't have happened." Hours later, he went further than a reference to past policy: he ordered local administrative officials nationwide to bar both ordinary citizens and off-duty government officials from carrying firearms in public, and to pursue immediate legal action against violators.
Thailand's Ministry of Education pledged tighter school security and financial compensation for victims' families, while UNICEF called for expanded mental-health support for children, noting the shooter's own young age raised distinct concerns beyond the gun-control debate. For now, the campus that was an ordinary secondary school Friday morning sits behind police tape, part of a national reckoning with gun violence that has repeated itself with grim regularity for years.
This is a developing story. Casualty figures, the suspect's identity, and details of the investigation may continue to change as Thai authorities release additional information.
