NONTHABURI: Relatives of the 14-year-old suspect in Friday's deadly shooting at Debsirin Nonthaburi School described him as a quiet, well-behaved teenager who spent much of his time playing computer games, while investigators examining his computer found evidence that he had viewed videos of school shootings in the United States in the days leading up to the attack.
The latest findings emerged as police continued trying to establish a motive for one of Thailand's deadliest recent school shootings.
