Yesterday marked three years since the shooting at a shopping mall in Copenhagen, Denmark, where a 22-year-old gunman killed three people and injured seven before being arrested.

I should have posted this sooner, but here it is.

The shooter has been identified as Noah Esbensen, he was armed with a SIG Sauer 200 STR match rifle, along with a pistol and a knife that were rendered unusable during the act.

Noah He had a history of contact with mental health programs, he had been diagnosed with psychosis and schizophrenia, he kept a diary where he wrote about his fascination with Randy Stair, a 24-year-old who killed three people and himself in a shooting in Pennsylvania, and with serial killers; He also posted some videos the day before the shooting where he simulated suicide with the gun he would use the following day. The weapon belonged to his father and was kept in a safe; he was sentenced to internment in a psychiatric hospital in 2023.

The identities of the three deceased victims have not been released to protect their families, but they were a 47-year-old russian man who was with his children, a 17-year-old danish customer, and a 17-year-old danish shopping mall employee.

Mass Of Murderers, a lost YouTube video made by Pekka-Eric Auvinen

Just thought this was interesting. He has actually a lot of videos of his from both of his channels that are still lost media. IIRC, only around 50 of his videos can still be found and viewed in archives and on social media sites and such today, maybe a little less? At least thats how many of his videos i've seen, including reuploads of his lesser known videos on YouTube and more videos that I think were considered lost media that were reuploaded by his friend on Tumblr and another site over the last 10-ish years. He made over 130 videos on his NaturalSelector89 channel according to his introduction video

Stuff I found reading transcripts of Cultural Philistine's videos

I read some transcripts of Cultural Philistine's videos and I was deeply disturbed during the whole reading. Here are some things I thought were interesting. I will admit, I teared up for some reason when he mentioned that he wishes he could hug people. I also thought in was interesting how he was aware that he was a loner and wasn't going to work or school.
