[1][2][3][4] Hours before the shooting, Dmitry Vinogradov posted a manifesto on Vkontakte expressing his hatred towards mankind and comparing humans to cancer.

[5][6][7] The gunman entered the warehouse on Chermanskaya Street at around 10:00 a.m. on Wednesday, 7 November 2012, dressed in camouflage gear and armed with two semiautomatic shotguns, a Vepr-12 and a Benelli M3 Super 90.

[1][12] The shooting ended when Vinogradov was subdued by a colleague, Yury Marchenko, after one of his guns ran out of ammunition, which saved lives, and he was then detained by Rigla's guards.

[6] Police arrested 29-year-old Dmitry Andreyevich Vinogradov, (Russian: Дмитрий Андреевич Виноградов) lawyer at the Rigla pharmaceutical company that owned the warehouse.

[18] Vinogradov stated his biggest regret was that he had failed to kill enough "genetic trash" (a term he used in his manifesto to refer to his targets).
