Pekka-Eric Auvinen was an 18-year-old high school student who spent much of his free time writing in his online blogs or posting videos to his YouTube channel. Auvinen’s online moniker was Sturmgeist89 and he spent the last few weeks of his like broadcasting increasingly extremist views and beliefs. Sturmgeist means ‘storm spirit’ in German.
Auvinen himself often featured in his online videos brandishing a .22 pistol that he named Catherine. In one of his online blogs, he wrote “I cannot say that I am of the same race as this miserable, arrogant, and selfish human race. No! I have evolved a step higher.”
His following videos and blog posts began to foreshadow his deteriorating mental state. The violent, angry nature of his videos and manifesto made it apparent that he planned the massacre in advance.
