Vladislav Roslyakov
Surveillance footage of the incident shows Roslyakov wearing black trousers and a white T-shirt emblazoned with the Russian word "НЕНАВИСТЬ" ("HATRED") as he carries an eight-shot 12 gauge Hatsan Escort Aimguard pump-action shotgun with a pistol grip. His clothing resembled that of Eric Harris, one of the perpetrators of the 1999 Columbine High School massacre, leading to speculation that the massacre was a copycat crime. According to some Russian tabloids, he had been a member of various Eric Harris and Dylan Klebold fanclubs on social networks, and had informed friends of his belief that "it would be good to have a massacre", specifically referencing Columbine High School massacre as an example. Furthermore, he had mentioned his belief in the two perpetrators being "awesome" Like perpetrator Eric Harris, Roslyakov committed suicide in the library of the college, by shooting himself with his shotgun.
