At around 11:40 am, Gordeyev, concealing his weapons with a bag and fur coat, went to his school armed with a small-caliber rifle and shotgun that belonged to his father, a police colonel. He threatened the security guard and went to his geography classroom, where he shot his teacher, 29-year-old Andrey Kirillov, in the stomach, then fatally shot him in the head upon seeing he was still alive. After killing Kirillov, he then took the class of 29 students hostage. Gordeyev then shot at responding police officers in the school, wounding Warrant Officer Sergei Bushuyev, 38, and Senior Sergeant Vladimir Krokhin, 29; Bushuyev later died at the scene, while Krokhin survived a gunshot wound to the shoulder. About an hour after the shooting first started, the Special Forces responded to the scene. Gordeyev initially called his mother before the Special Forces called in his father to negotiate with him. He initially spoke with Gordeyev on the phone for fifteen minutes before being brought into the school with a bulletproof vest to personally talk to him; thirty minutes afterward, Gordeyev released the hostages. At around 1:00 pm, Gordeyev surrendered to authorities and was captured. A Russian report stated that a total of eleven shots were fired by Gordeyev during the shooting.
Victims
Two people were killed in the shooting, while a third was wounded. The victims were:
15-year-old Sergey Gordeyev was identified as the perpetrator of the shooting. He attended School No. 263, had a very good reputation, and was due to an excellent record being described as a "model student" who sets up "an example for the whole school". Concerning a motive of shooting, first, there arose two versions. According to the most sound one, Gordeyev opened fire from revenge against the geography teacher who was trying to interfere with his planned graduation with honors – and Kirillov was fixed upon as the teacher Gordeyev had conflicts with. Another version suggested that Gordeyev was suffering from an emotional disorder, and had no previous apparent conflicts with either teachers or fellow pupils although some described him as "strange". A medical examination confirmed that Gordeyev has symptoms of mental disorder. The court sentenced him to involuntary treatment in a psychiatric hospital. Later, the court also obliged the parents of Gordeyev to pay a certain sum of money in support of the son of the killed teacher.
