More on this incident

Police and forensic officers who searched a home in Bang Bua Thong district have identified one of those killed in connection with the Aug shooting at as Somjit Yimruang, 73, the Bangkok Post reported. No other victims have been named by the authorities in the reports cited here. Gunfire erupted at the state-run secondary school in province, on the morning of Friday, Aug , while students, teachers and school staff were on the premises. Accounts of the toll differ: The Straits Times and the Bangkok Post reported people killed; the Bangkok Post also reported killed, with cited as saying people, including the gunman, died; The Straits Times elsewhere reported killed; Geo News reported ; and Thailand News reported . The number injured was reported as by the Bangkok Post, by The Straits Times and by Geo News. Hospital officials said a 12-year-old girl died later on Friday of severe gunshot wounds, becoming the ninth casualty. The Straits Times and the Bangkok Post reported that the gunman ; Geo News stated that the 14-year-old boy turned the gun on himself. Police said on Sunday, Aug , that the teenager had watched violent content online, and the government promised new safety protocols for schools. Atthapol Anusit, deputy commissioner of the Provincial Police Region 1, said: "According to witness interviews, the perpetrator had begun showing interest in studying the use of firearms for some time, about one to two years," and: "After examining the PC, it was found that the child had watched social media content involving violence." Mr Atthapol also said a teacher confiscated a BB gun, a type of air gun, that the boy took to school last year. Police said searches for and study of information about a school shooting in the United States on the teenager's computer date back to around July 30. The Straits Times, citing unattributed reports, said video clips related to school shootings abroad were viewed on the suspect's computer since July 30; no named official has confirmed that on the record. Police said they believe the 14-year-old suspect travelled to on the morning of Aug after his grandparents were killed at their home in Nonthaburi province. Police have not stated a cause. The response involves police, Provincial Police Region 1, the national police, forensic officers, the Nonthaburi Provincial Police Office and Plai Bang police station, and the Bangkok Post reported that police hope witnesses can shed further light on what happened. Later on Friday, relatives held a traditional ceremony at the school to invite the spirits of the to return home, the Bangkok Post reported. The school has suspended classes for all year levels from Monday to Friday of the following week, with teachers and staff instructed to work from home and classes resuming Aug 17, according to the Bangkok Post. The Straits Times reported that parents have been asked to make sure their children returned home safely and to closely monitor their emotional condition, and that education district directors across the country were due to meet on Aug to discuss enhanced school security; Thailand News reported that the cabinet declared school safety a priority after the shooting. Education Minister Prasert Jantararuangtong said the incident "will therefore prompt a review of security procedures, particularly measures to prevent weapons and other dangerous items from being brought onto school premises." Mr Anutin said the education minister "would need to do something to assure the parents of all students that we will have better safeguarding measures with respect to any children carrying guns into schools." The prime minister also said: "This is violence, but it is not caused by criminals. It is caused by an individual who had carried a lot of pressures and tension," adding: "So he is not a street criminal, he's not a robber, so this really has nothing to do with security measures in the school," and that "he intentionally came to school today to commit this unfortunate case."

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
