She was talking to me when (the gunman) showed up and shot her,” she said.“I couldn’t see anything but a [cloud] of dust. He walked from room to room. My desk was very close to the teacher. I had to climb over the school fence to escape with other friends.”The student’s mother said her daughter later told her: “I thought I’d never see you again.”Another student told Reuters he initially thought the sound of gunfire was firecrackers or someone hitting something.“I didn’t think it was a gun at first,” he said.“There were many shots: bang bang bang. Then it went quiet. Then it started again.”Police said the attack began shortly after 10am at Debsirin Nonthaburi School in Bang Kruai district, triggering panic as staff evacuated students and authorities searched the premises.The school belongs to the Debsirin network, one of Thailand’s oldest and most prestigious educational institutions, with its original Bangkok campus founded in 1885 by Thai King Chulalongkorn.Thai authorities said the teenager lived with his grandparents, who were found dead at home before the school attack.Deputy Interior Minister Polapee Suwanchawee said police had found evidence suggesting the suspect was an avid gamer, while a teacher described him as a “good kid with good study records” who was not known to be aggressive.Thai police said they were investigating the shooting to determine the cause and proceed with legal action.The motive behind the attack remains unclear.
