NONTHABURI, Thailand – Police investigating the deadly shooting at a school in Nonthaburi are examining several possible factors behind the attack, including personal stress, family issues, online activity, and the suspect’s access to firearms. National Police spokesperson Pol. Lt. Gen. Trairong Phiwphan said the suspect arrived at the school as usual before leaving the classroom and carrying out the shooting.
Police have inspected two key locations linked to the investigation — the suspect’s home and the school. At the residence, officers found two deceased family members, identified as the suspect’s grandfather and grandmother. Investigators initially believe they died as a result of the suspect’s actions. At the school, the area was sealed off for forensic teams to collect evidence, while police coordinated with hospitals to confirm information about the injured and deceased.
Authorities later confirmed that eight people had died, including school personnel and staff members, as well as the suspect. No students have been confirmed dead. More than 30 people were injured, with many suffering minor injuries while trying to escape. Nine victims remain under close medical observation, including some who sustained gunshot injuries. Police are continuing to interview witnesses, relatives, and people close to the suspect, while examining electronic evidence collected during searches of the suspect’s home.
Investigators found that the suspect had played online games involving firearms, including World of Tanks (WoT) and Roblox, and had searched for information related to violent incidents. Police said they are examining whether these activities were connected to the motive behind the attack. Friends told investigators that the suspect had previously complained about stress related to schoolwork, homework, and strict expectations from both family and school. However, police said there is currently no confirmed evidence that the suspect had been bullied or had conflicts with classmates.
Regarding possible firearms training, Pol. Lt. Gen. Trairong said police have not found evidence that the suspect received formal weapons training. However, officers will continue investigating whether the suspect learned about firearms through other sources, noting that information about weapons can be easily accessed online. Investigators also reconstructed the sequence of events and found that the suspect brought the firearm into the school inside a bag. The suspect reportedly fired until the first magazine was empty before changing to a second magazine. More than 30 rounds of ammunition were still found remaining.
Police are also checking the origin of the firearm and whether the suspect had any previous history of mental health treatment. No confirmed information has been reported on that issue so far. Following the incident, the Royal Thai Police ordered all units nationwide to strengthen enforcement against illegal carrying of firearms in public areas, including weapons that may be legally owned but are not permitted to be carried outside authorised locations. Police checkpoints have been instructed to strictly enforce firearm laws to prevent similar incidents.
Pol. Lt. Gen. Trairong said investigators have not ruled out any possible motives, including the influence of online content, gaming activity, or possible social conflicts. Officers are continuing to review evidence, including online searches and digital records, to determine what led to the attack. Investigators also found that the suspect had viewed news reports about a mass shooting in the United States on July 30, 2026, which is among the details being examined as part of the ongoing investigation.
