A 14-year-old boy accused in a deadly shooting outside Bangkok used online material and firearm-related learning before carrying out a rampage, Thai police say. Police allege he killed his grandparents at home, then shot dead people at his school, before turning the gun on himself.

Police across the reports describe the suspect as having watched violent content online and using social media to learn how to use a firearm. One outlet also adds that an air gun was confiscated by a teacher last year, indicating earlier firearm access or interest. Another outlet cites a police deputy commissioner saying the suspect showed interest in studying firearm use for about one to two years.

Some coverage also links the case to wider safety and policy questions. Japan Times and the South China Morning Post note the attack’s impact on debates around firearms control and school safety protocols in Thailand, as investigators continue and officials respond to the incident.
