Polish police:
"On a cabinet at Michal O.'s workplace, the researchers found the abbreviation GGER, which means good game Elliot Rodger. This is a direct tribute to the American attacker who murdered 6 people in 2014, motivated solely by sexual frustration and pathological misogyny.
The shooter computer had a huge interest in Breivik, searches for Ted Kaczynski and Charles Manson.
Michael O was closely associated with the dark side of the TCC (True Crime Community). In these pathological corners of the internet, crimes are unreservedly glorified, and mass murderers are given celebrity status to emulate.
There was no grand political plan here it was pure magic of destruction, violence and killing for its own sake.
We are dealing with the radicalization of an alienated, rebellious person, fascinated by serial killers and mass shooters. ".
