NONTHABURI — 7 August 2026, police examining the computer of the student who carried out the shooting at Debsirin Nonthaburi School found a YouTube watch history containing videos about school shootings and mass shooters, as well as Roblox links related to handling firearms.
At 12:28 on Thursday, police responded to reports of two people shot dead at a house in Bang Bua Thong district, Nonthaburi.
They found a 73-year-old man dead from gunshot wounds in the kitchen. His 74-year-old wife was found dead on a bed on the second floor.
The couple were the grandparents of the 15-year-old student accused of carrying out the shooting at Debsirin Nonthaburi School.
Investigators said the boy used his grandfather’s 9mm handgun to shoot both grandparents dead in the early morning before travelling to the school, where several people were killed and injured.
During a search of the house, officers found a desktop computer with a search history that included YouTube videos about overseas school shooting incidents, as well as Roblox links related to handling firearms. The videos were accessed on 30 July, more than a week before Friday’s shooting.
