New information from MF DNES newspaper show, that during adolescence he had shot an air rifle at a tent where his sister slept and was disturbingly interested in mass murderers and violence. His worsening psychological state was probably also affected by issues in his family.
David Kozák had shown propensity to violence since his childhood. One of the key moments which shows Kozáks increasing aggressivity happened during his studies on Malostranské gymnasium (high school). During his stay at summer camp he shot an air rifle at direction of tent where his sister slept. Kozák later related this incident to his classmates. “Friends had challenged David to retell the story. He told it like funny a anecdote, I however did not find that funny” said his teacher according to MF DNES and with this information she had confronted Davids father. “I had conversation with Davids father, who had told me to take it easy, that they have guns at home and that David has been isnstructed and knows how to handle firearms.” Added the professor.
Next to firearms, David in his youth also showed interest in mass murderers. He was fascinated most by Anders Breivik, Norwegian terrorist, who in year 2011 murdered 77 people. Kozák had systematically researched information about him and likewise was interested in other murderers, including Vikotr Kalivda, who was known as “Forest murderer”. This interest in violence and brutality found its way in Kozáks taste when it came to entertainment. Obsessed mainly by Japanese anime, which oftentimes contained extreme violence.
One of the characters that in particular captured Kozáks interest was Keiji Kiriya from Japanese manga comics All you need is kill. Police psychologist stated that David had chosen this character (Keiji Kiriya) because he put impression on him. And later (starting spring of 2023) he himself started to emulate him by changes in his lifestyle. Kiriya is characterize as lonely warrior without any social contacts, focused only on his fighting abilities which Kozák viewed as ideal.
Kozáks violent fantasy was moreover not limited to just mass murderers. Evidence was found in his computer during investigation that pointed to obsession about violent pornography. Kozák viewed mostly “Asian production” where performed women with makeup that made them look like zombies or corpses.
Family environment
Tension was present even in his family life. Even though he grew up in well off family, he felt strong pressure on his academical success which took negative toll on his psychological state. “While family describes David before his actions as content and active, his classmates say that David was stressed. Kozák himself admits that he is under pressure (does not sleep, does not eat enough, drinks only green tea)” States report put together by investigators.
Parents who were cause of the pressure on his academical performance had become target of his wrath. Kozák openly admitted, that he though about how to physically hurt them. “I had put thoughts about suicide to side, its more like eventuality. For instance during arguments with parents, I want to somehow punish them before I carry on with suicide, I want to do something to them before that” Wrote Kozák in October of 2022.
Plans to kill his parents were amended by addition of intention to destroy their family house in Hostouň. Kozák wanted to blow up the house by use of IED. He planned everything with care and precision and only by mere chance he did not succeed according to investigators.
Test before the massacre
Kozáks homicidal tendencies ended by his attack on philosophy faculty in December of 2023. This act was however not his first. Few days before that he shot two people in Klánovice forest, probably at random. “I would have shot anyone” he wrote in letter that he left.
This double murder served as confirmation of his ability to kill. “Suspect needed to make sure he is indeed capable of killing someone” States police psychologist in her report.
