The deadly attack by a student at Debsirin Nonthaburi School appears to have resulted from a combination of factors such as family problems, issues at school, academic pressure, conflicts with friends and exposure to violent online content, a senior police officer said on Sunday.
Investigators had questioned 17 witnesses - teachers, classmates and close friends of the student. Evidence gathered so far suggested Friday’s shooting was not triggered by a single issue, Pol Maj Gen Atthapol Anusit, deputy commissioner of Provincial Police Region 1, said after a meeting to review the progress of the investigation.
