YouTube shooters

This thread is basically for documenting active shooters who had YouTube accounts, had commented on videos, or made disturbing videos on YouTube. I'll start off with Pekka-Eric Auvinen the Jokela Finland School Shooter who shot and killed 8 people before turning the gun on himself at his highschool on November 7th 2007. (sig sauer mosquito) Auvinen had 2 youtube accounts NaturalSelector89 and Sturmgeist89 after that one was banned. He made videos on topics of relgion, natural disasters, terrorist attacks, and mass shootings including Columbine. He posted videos of his gun he got to test shooting it and his final video was "Jokela Highschool Massacre - 11/7/2007" A video with a picture of Jokela Highschool being cracked with an effect then a red picture of him with a gun aimed. his last vid Feel free to add to the thread.[You must be registered and logged in to see this image.][/url][You must be registered and logged in to see this image.]

Anders Breivik had a YouTube account named BerwickAndrew where he posted a video warning people about the danger of cultural Marxism and Islamic brainwashing.
Unfortunately, the account was deleted shortly after the shooting, it's such a loss, words can't describe my sadness and anger over this unspeakable tragedy!!

The guy who shot up the subway in Brooklyn had a YouTube channel, his name is Frank James, and it was disturbing.

NOT to be confused with the super-hot Frank James who has a Meyers Briggs YouTube channel.

I think the YouTube shooter had a very odd channel too. I forgot her name.

Nasim Aghdam injured three people when she opened fire at Youtube's HQ. Her channel was bizarre, consisting of content catered toward vegans, and other oddities.

It's full of conspiracy retardation that was commonplace on YouTube in like 2010-2013, but his videos are especially schizophrenic.
Here's a reupload of a video he made where he claimed his community college was responsible for "genocide" whatever he meant by that:
