Criminologist urges caution over Nonthaburi school shooting

A criminologist has warned against drawing quick conclusions about the motives behind a school shooting at Debsirin Nonthaburi School in Bang Kruai district, Nonthaburi, which left many people injured and dead.

The incident involved a Mathayom 2 male student, who opened fire on fellow pupils and teachers inside the school. Details of the suspected gunman's motive have not been confirmed by authorities.

Speaking on 7 August, criminologist and academic Ajarn Trin Phothiraksa said Thailand needed to learn serious lessons from such attacks, but stressed that claims about mental illness, bullying, resentment towards teachers or violent games should not be treated as fact without evidence.

Motive and risk factors must be separated

Trin said behavioural criminology distinguishes between a motive and risk factors. Bullying, family problems or mental health difficulties may be relevant factors, he said, but do not automatically lead a person to carry out a shooting.

He said information known so far pointed to several possible issues, including long-term bullying, alleged harassment by a group of students, a dispute involving a girl who reportedly complained to a teacher, and the student's reported viewing of overseas murder and mass-shooting videos on YouTube.

However, he said these were only possible explanations and should not be treated as established until properly investigated. The gunman died after the incident.

Trin also questioned why people in the gunman's household had been killed if his intended grievance was against people at school. He said it was an unusual aspect of the case and that outsiders could not know the offender's state of mind at the time.

Calls for metal screening and school psychologists

The weapon was owned by the student's grandfather, raising questions about gun storage and access by children. Trin said cases in which young people use firearms belonging to parents or relatives as weapons or for threats were a repeated warning for families.

He proposed metal detectors and weapons screening at places with large numbers of people, including schools, hospitals and cinemas, rather than restricting such systems to airports, Government House and parliament.

Citing figures previously reported by the Ministry of Social Development and Human Security, he said offences against life and bodily integrity committed by children and young people rose about 58.7% between fiscal years 2019 and 2023. Weapons-related cases rose about 92.1%, with most offenders of secondary-school age.

Trin said schools should have psychologists and counselling rooms, while teachers should speak with pupils and parents on both sides when bullying is reported. He added that games themselves were not inherently to blame, though violent content could act as a trigger for children who were already vulnerable.

I think he is right, no speculations, but i believe that there is a big neef now for all education offices to hold a meeting with all schools and teachers together with psychologists, and specialists to talk about possible signs that kids are not happy because of bullying or whatever other reason and how to deal and handle in such cases. In some stories in the Thai news they mention that the kid asked for help several times but that he not was heard. I think if teachers are more aware of such signs they can deal quicker and better. Besides that there should be help for youngsters in general. Students who fall from the schoolbuilding would not do it if there was confidential person or way to talk too. In Europe most countries have a suicide line or help lines to talk about mental problems, as herr in Thailand everything is waved away or silenced to death.

Here we go again....blame it on the guns instead of a kid with behavioral issues! If a kid with a sick mind wants to kill and can't get a gun, he'll use a knife or a hammer or any number of other tools available to him. Somebody knew this kid had problems, and nobody spoke up.

7 dead, 15 injured and 1 in critical condition. A 14 year old with a knife or hammer could not inflict such harm. Your comment that somebody knew this kid had problems, and nobody spoke up is a huge assumption. A teenager showing anti-social behaviours is not exactly a rarity.

  1. A potential lack of parenting. Or parents who are absent or lacking any parenting skills. Don't have kids if you can't look after them. Period.

  2. The grandfather was not cautious with his guns. He needs to be charged and imprisoned for the rest of his life.

  3. Even if the problems this piece of crap kid had were known, the extreme lack of mental health access here could have prevented anything being done about it.

  4. The extreme weakness that comes from the practice or face means that even if the bullying was reported, there may have been no consequences. Likewise it might have prevented counseling of the creep himself. One of the many consequences of a predominantly tribal culture. In my opinion, of course.

How do you put a dead man in prison

Perhaps they can embalm him and put them there with a big plaque saying

I am the grandfather of the serial killer who provided him with a weapon.

It was an honest mistake, okay?

'The grandfather was not cautious with his guns. He needs to be charged and imprisoned for the rest of his life. '

Imprisoning dead bodies maybe a bit extreme.

The grandson was not a 'serial killer' as the definition of that is generally - the unlawful killing of two or more victims by one culprit in separate events.

I am also not sure if the grandfather 'provided' the weapon as that would suggest some criminal negligence or intent. As the grandfather was shot by the culprit it is more likely that the firearm was not kept securely away from the culprit.

Why is it after the event the so called experts all come out with their advice on what happened and the probable causes

Always reactive not proactive

The usual reason the killers had mental problems which is a easy kop out

This was not a crime, it was stress related according to Anutin:

https://www.thaiexaminer.com/thai-news-foreigners/2026/08/08/anutin-blames-stress-at-scene-of-fridays-school-massacre-told-reporters-no-crime-was-committed/

Full reading of the article you helpfully quote does not show that the PM specifically stated - this was not a crime. The article explains the difference in application of Thai law when dealing with persons under 15. But for foreign press to accept that would rob them of a catchy headline. I don't think there many people in Thailand that would not classify the shootings as a crime, the PM was simply explaining the law as written and applied in Thailand.

By not keeping the weapon locked up and safely secured, he did provide the weapon for the mass murder.

The guy lists the facts and circumstances we already know. These so-called experts are very good at hindsight. The fact is that young people are becoming much more aggressive. In Europe, the harmful immigration of North Africans and sub-Saharan Africans is largely to blame. Another aspect is that social media like TikTok, which influences and indoctrinates young, growing teenagers, is extremely detrimental to their behavior. Australia has started banning social media for teenagers under 16. France was the first country in the European Union to pass a law prohibiting access to social networks for those under 15.

No, you're partly not right.

It is indeed important to know why this boy needed a gun to solve his problem, no matter where the gun was nor to whom the gun belonged.

It's important to learn from this incident how to prevent similar cases in the future. Counselling rooms and private talk with a teacher in provided school areas is also important.

For the victim's families it might be even important to know why it happened.

I disagree with you, newbee2022, when you say it is important to know why this boy needed a gun. He did not need a gun, he used a gun because he had access to a gun. Thailand has more guns than any other country in S.E. Asia. Why? That is what is important to know.

Anuthin did not say the shooting was not a crime.

The rumour likely stems from a misinterpretation of a specific statement he made during a press conference while visiting the shooting site. When discussing the 14-year-old shooter, Prime Minister Anutin stated that the boy was "not a hardened criminal" or a "street criminal," but rather a minor who acted under severe, long-term emotional and academic stress.

The Prime Minister framed it as an issue of severe youth mental health and accessible firearms rather than organized crime.

He explicitly emphasized that the crimes were committed by individual offenders and should not be seen as a reflection of Thailand's overall societal safety.

Far from denying that a crime took place, Anutin instructed police investigators to build comprehensive case files so the courts could impose the toughest penalties permitted under Thai law.

That's not right.

Why should it be important in this case why Thailand got most guns? And even this you would have to consider: guns with the police, guns with the army, guns in families registered, guns unregistered. So the simple figure of guns in Thailand is irrelevant.

To avoid similar cases it is indeed necessary to know, who's the owner of the guns, why the boy needed a gun and what made him use the gun. Did he got access to similar videos before? And last, I'll remind you of a case in New Mexico where Meta is to pay almost half a billion Dollar because they did not protect under age kids to watch those videos and did not protect them to be addicted to Meta products.

Solution: access only by finger print.

Your subjective interpretation of the word 'provide' would not pass any legal standard for prosecution. By extension you could accuse any legal weapons manufacturer of 'providing'.

The grandfather may well have been negligent in securing the weapon and he and his wife appear to have paid the price for that.

BS! The perpitrator with a hand held weapon will take a lot more time to commit the offence rather than some fruit cake with a gun so the possability of securing the situation has been enhanced.

I'm noticed that since March 2020, those individuals who believe that they have the corner on being an "expert" spend an inordinate amount of energy telling other humans "not to turn on your own mind or attempt to use your own inherent analytical abilities."

When tragedies like this happen, people look for answers. Unfortunately they are often told to "shut and up stop asking questions."

That has never been the correct answer to my own efforts and understanding the world around me.
