The mother of the 18-year-old attacker told the investigators about this during interrogation, reports Life.ru.
It is noted that he suffered from bronchial asthma, therefore "the path to law enforcement agencies through the army was, by and large, closed for him."
The young man entered the Faculty of Law with a degree in forensic examination.
