Governor Mükerrem Ünlüer has granted permission to investigate four people following a school attack that left 10 dead. Those facing investigation for misconduct include former school principals, a guidance counselor, and an assistant principal. The governor denied investigation requests for 11 other public officials, including former provincial and district national education directors. The decision noted that the student attacker, İsa Aras Mersinli, had severe problems and often slept during lessons. These problematic behaviors were known to others. Instead of taking precautions, the authorities allegedly ignored the situation.
