A teenage student’s rampage outside Bangkok left families counting the dead at two scenes, and the casualty figures kept shifting as officials pieced it together.
Story Snapshot
- Police said a 14-year-old student killed his grandparents at home before the school attack.
- The shooting unfolded at Debsirin Nonthaburi School in Nonthaburi province, northwest of Bangkok.
- Officials first reported seven deaths, then later confirmed eight and, in later reporting, nine.
- Early reports also varied on who died at school and how many people were wounded.
What Happened at the School and the Home
Thai authorities and wire services said the violence began at the family home, where the boy killed his grandparents before heading to school.
Reuters said police reported that he then fired at least 26 bullets with a gun that belonged to his grandfather, and that 34 more rounds were found. The school was identified as Debsirin Nonthaburi School in Nonthaburi province, northwest of Bangkok.
The attack then moved room by room. BBC video coverage quoted a witness who said the shooter was going from classroom to classroom and firing into rooms, while investigators searched the site and helped students escape.
That detail matters because it shows why the scene turned chaotic so fast. It was not a single burst in one place. It was a moving attack across the school.
The Death Toll Changed as Officials Confirmed More Facts
The headline number changed several times. AP and Reuters first reported at least seven dead, with five killed at school and two grandparents dead at home.
BBC later quoted Prime Minister Anutin Charnvirakul as confirming eight deaths, including the gunman, his grandparents, and five teachers. Later reporting raised the toll to nine after a wounded schoolgirl died in hospital.
That shifting count does not change the core event. It shows how fast-moving mass violence can force officials to update the record in real time.
AP reported 23 wounded at Bangyai Hospital, Reuters reported 23 wounded, and BBC said more than 30 were injured in live updates. The injury figures also changed as hospitals and police refined their totals.
Why the Victim List Was So Confusing
The hardest part of the early reporting was not whether the attack happened. It was who died where. Reuters said the school dead were teachers and staff.
AP said five school staff members, including teachers and administrators, died. BBC’s live updates later said five teachers were killed. CNN’s early reporting even said students were among the dead before later revisions narrowed the list.

That kind of correction cycle can make a tragedy feel less certain than it is. But the main facts stayed steady: a 14-year-old student was identified as the suspect, he was said to have killed his grandparents first, and he died by self-inflicted gunfire at the school.
The rest was the hard work of confirmation, which came in waves as police, hospitals, and officials matched names to bodies.
Why This Story Cut So Deep in Thailand
This was not just another school shooting. Reuters described it as Thailand’s worst mass killing in nearly four years, and later reporting tied the attack to renewed debate over firearms control.
That explains why the story spread quickly and why officials moved fast to brief the public. When a school becomes a crime scene, people do not only fear the violence. They fear how easy it was for it to happen.
There is also a simple human reason the story stayed on the front page: the age of the suspect. A 14-year-old student is not the image people expect when they hear about a mass shooting
. That detail gave the event an extra layer of shock, because it combined youth, family violence, school violence, and a final act of self-destruction in one morning. It was the kind of case that leaves no side untouched.
