In another case of a young man who purportedly "
wouldn't hurt a fly" a student at Kerch Polytechnic in Crimea killed 19 in what might be a copycat Columbine attack. Vladislav Rosylakov, 18, reportedly held a grudge against the staff at the college, arriving there after a period of absence with weapons concealed in two backpacks. He later shot himself on the second floor of the building.
