EDIT: Ah, just a typical loon.First he kills his father, then random students at the Faculty of Philosophy
Kozak murdered his father in the nearby town of Hostoun before heading into the Czech capital where he began randomly shooting people from the balcony of Charles University Arts faculty.
In the lead up to his killing spree, he is thought to have kept a diary in Russian on messaging app Telegram, writing: 'I want to do a school shooting and possibly suicide.'
The gunman is believed to have been inspired by a school shooting carried out by 14-year-old schoolgirl Alina Afanaskina in Russia earlier this month.
