Уголовный кодекс Российской Федерации
Konstantin Mrykhin was convicted of "providing services not compliant with safety requirements, committed by an organized group by prior agreement, which negligently led to deaths of two or more people" (Article 238, part 3 of the Criminal Code of Russia) on 14 May 2012 and sentenced to 6.5 years of imprisonment (maximum sentence on that charge is 10 years, but Mrykhin pleaded guilty to the charges and therefore was not subject to a full trial; the maximum sentence in that situation is automatically reduced by 1/3). He was also sentenced to paying 200,000,000 rubles (approx. 5,000,000 euros) in compensation to the victims.
