A teenage Thai student has killed seven people and himself during a rampage at home and school. Each was killed by a single gunshot to the head, a Thai police official said. One was a female Thai language teacher who he shot in the eye, according to a timeline of the incident shared by Thai police. "He then walked down the stairs and encountered the school's deputy director and the director's secretary, who were going up the stairs to check on the situation," Dejrapee told Reuters. The boy's motives remain unclear, though Thai Prime Minister Anutin Charnvirakul told reporters he was stressed from his studies.
