The 14-year-old opened fire at around 10am on Friday at Debsirin Nonthaburi School in Nonthaburi province northwest of the Thai capital before apparently taking his own life. He also appeared to have killed his two grandparents at his family home earlier in the morning, officials said. The school had posted a message on Facebook on Friday seeking blood donations for two students, including the girl, who was in seventh grade. Fourteen people remain hospitalised, of whom seven remain in critical condition on Saturday, according to Thailand’s Health Ministry. Relatives claimed the bodies of eight people from Bangkok’s Institute of Forensic Medicine: five school staff, the accused shooter, and his grandparents.
