A 14-year-old boy killed his own grandparents at home, then walked into his high school outside Bangkok and opened fire on his teachers before turning the gun on himself.
Story Snapshot
- Police say a 14-year-old student shot and killed his grandparents at their home near Bangkok, then attacked Debsirin Nonthaburi School.
- At least seven people died in the two attacks, including the shooter, and the toll later climbed as wounded victims succumbed to injuries.
- Police say the boy used his grandfather’s handgun and fired at least 26 rounds inside the school.
- Dozens more were hurt, with hospital officials reporting some victims in critical condition in the hours after the attack.
A Morning That Began With Family Violence
The attack did not start at school. Thai police say the teenager first killed his grandparents inside the family home in Nonthaburi province, just northwest of Bangkok, early Friday morning. He then traveled to Debsirin Nonthaburi School, where he was enrolled as a student, and began shooting people he knew by sight every day.
At least seven people have been killed after a teenage boy shot his grandparents and then opened fire at a school near Thailand's capital, Bangkok.
The country's prime minister, Anutin Charnvirakul, called the attack "well prepared".

Witnesses described a scene of pure terror inside the building. One student told reporters the gunman moved “from classroom to classroom, firing into the classroom,” as police and ambulances swarmed the campus.
That kind of methodical, room-by-room violence is what separates a chaotic outburst from a planned attack, and it is why investigators are treating this as premeditated rather than impulsive.
The Weapon Came From Inside the Family
Police say the handgun used in both shootings belonged to the boy’s own grandfather, one of the two people killed at the house that morning. Investigators reported the teenager fired at least 26 bullets during the rampage.
That detail matters. It was not a stranger’s gun smuggled in from outside. It was a firearm already sitting inside his own home, in the hands of family he then killed first.
Thailand keeps tight civilian gun laws, yet this attack still happened with a legally owned family firearm. That should give pause to anyone who assumes strict gun laws alone solve the deeper problem.
A troubled teenager with access to a gun and a plan found a way, regardless of the country’s regulatory framework. The failure here looks less like a paperwork gap and more like a supervision and mental health gap that no law fully closes.
Casualties Climbed As Officials Confirmed More Deaths
Thai Prime Minister Anutin Charnvirakul confirmed eight deaths in total, including the shooter, his two grandparents, and five teachers killed at the school. Hospitals reported dozens of wounded, with one facility, Bangyai Hospital, saying 23 people were hurt and 10 remained in critical condition.
Those numbers shifted repeatedly in the first day, which is normal in the immediate aftermath of a mass casualty event, not a sign of confusion about what happened.
Why The Numbers Moved And What Stayed Constant
Early wire reports gave death tolls ranging from six to eight, and some outlets later reported the toll rising further as critically wounded victims died from their injuries.
That kind of movement is common after any mass shooting, since hospitals and police need time to confirm identities and causes of death. What never changed across any report was the basic shape of the tragedy: a student, a grandfather’s gun, a home, then a school.
Some early coverage also blurred who exactly died at the school, describing the victims at various points as staff, teachers, or students before settling on five teachers as the confirmed school death toll.
A Nation Grappling With Repeated Tragedy
Thai officials called this the country’s worst mass killing in nearly four years, a grim marker in a nation not accustomed to school shootings on this scale. Reports have already connected the attack to broader conversations about firearm access and school safety across Thailand.
That conversation matters, but it should not overshadow the immediate reality facing grieving families: children and teachers went to school on an ordinary Friday morning and did not come home.
A young shooter, a family firearm, a school turned into a crime scene, and a community left asking how a 14-year-old crossed such an unthinkable line. Grief transcends borders, and so does the hard question of what failed before the first shot was ever fired.

Thai investigators are continuing to piece together the full timeline, and officials have signaled more details will follow as forensic work concludes.
For now, the confirmed facts stand on their own: a student armed with his grandfather’s gun took at least seven lives, including his own, in a single morning that began at home and ended in a classroom.
