Two grandparents found shot after Nonthaburi school attack

Police investigating the shooting at Debsirin Nonthaburi School have found two further bodies at the suspected gunman's home in Bang Bua Thong, Nonthaburi. The victims were identified as the pupil's grandfather and grandmother, both shot in the head.

The discovery was reported at 12.49pm on 7 August. Investigators believe the teenager killed his grandparents before travelling to the school.

The school attack left 15 people injured and seven dead, including the pupil suspected of carrying out the shooting. He used a 9mm firearm to shoot himself and later died while being taken to hospital.

Police examine home and weapon source

Nonthaburi provincial police investigators went to the suspect's house, in a housing estate off Soi Wat Lat Pla Duk in the Bang Bua Thong area, to examine possible motives and gather further evidence.

The two bodies were found inside the property during that search. Reports said the suspected gunman had lived with his grandparents throughout his life, while his parents had separated when he was a child. Police are continuing to establish the sequence of events.

Deputy national police chief Pol Gen Samran Nuanma, Pol Lt Gen Nopasilp Poolsawat, attached to the Office of the National Police Chief, and Deputy Interior Minister Polpheer Suwanchawee attended the school scene.

Authorities said their work includes collecting forensic evidence, questioning witnesses, tracing the origin of the firearm and examining the motive.
