David Kozák Info – Part 1: Childhood and School Years
Family Background and Home Environment:
The family was described as respectable and well-off, leading a secluded lifestyle.
Kozák was raised quite strictly. Witness quote: “The father raised the boy in a very simple way. No girls, no parties, no hobbies. He had to study constantly; mainly, he needed excellent results at school”.
Kozák was not involved in village life, had no friends or contact with residents, and spent most of his time at home. A postal worker recalled that he often came to the post office, picked up his parcel, and left without speaking to anyone.
According to village witnesses who saw Kozák, he looked like a boy who probably stayed at home reading books.
Kozák did not attend the local primary school because there were too few children to open a first-grade class, though his sister studied there.
Kozák’s father, Stanislav, was described as kind, intelligent, quiet, and solitary. He held a managerial role in security at Prague Airport, was well-liked by colleagues, and was called “one of the best colleagues and managers”.
Kozák’s mother, Romana, had a determined character, and worked as a civil engineer. She also served as deputy mayor of the village for two years.
Kozák’s sister was academically successful and worked at the airport. She studied “Population Protection” at the Czech Technical University, writing a highly rated thesis on airport security measures during crises such as pandemics, fires, and terrorist attacks.
Kozák felt stressed at home, saying his parents pressured him academically and punished him for not completing household duties. He also complained of poor sleep and appetite.
Later, during a psychiatric appointment, he also said he felt pressure from his family to socialize more (which he struggled with).
He described his relationship with his family as the closest relationships he had, but noted that he did not have deeper emotional bonds with them. He called his sister and mother “the generals of the family”.
School Background and Development:
Kozák consistently excelled academically and participated in competitions from school onward. He later received an award from the Polish Institute in Prague for his work on the 1846 Kraków and Galician peasant uprisings.
His classmates confirmed that he studied well and was intelligent. “Everyone thought he would achieve the greatest success among all our classmates,” said one classmate to police.
Despite his strong academics, Kozák struggled socially. Former classmates described him as a quiet, inconspicuous introvert who spoke to very few people.
He had significant difficulties forming contacts with people from a young age, which he later complained about in sessions, saying he “did not feel them” and did not understand the concept of friendship.
His romantic life was also unsuccessful. In school years, he awkwardly pursued a girl and behaved in a rather frightening way, resembling stalking. He bought her an expensive birthday gift, but she rejected him and told him not to contact her again.
Some villagers noted that he was willing to talk, or at least tried to talk, with girls, but he was never able to form relationships.
Encouraged by friends to brag, Kozák fired an air rifle at a camp tent where his sister was inside, presenting it as a joke; his father later dismissed concerns, noting they had weapons at home and that David was trained to use them.
In secondary school, he made three friends: two boys and a girl, with whom he remained in very occasional contact even during his university studies.
One friend declined to comment on his relationship with Kozák. Another said that at school they discussed video games, military topics, or history. Witness quote: “We were united by a shared interest in weapons. Sometimes in upper grades we bought air guns, but we never went out to play together”.
Kozák likely had his closest relationship with a girl who later played a key role in the case, as she accompanied him to a psychiatrist and called a hotline on the day of the crime; however, he did not consider the relationship close, saying they only communicated occasionally.
Mental health issues began in school and worsened at university, especially during lockdowns. Thoughts of death emerged in his teenage years, linked to feelings of emptiness, lack of pleasure, loss of meaning, and unmet self-realization.
Interests and Preferences:
Kozák was interested in anime series with unusual, strange themes, partly pornographic. Witness quote: “It seemed to me that it was more an attraction to strangeness than to the content itself, or to pornography”.
Later, this developed into an interest in a certain type of adult movies, preferably Asian, including films in which women are depicted as zombies or corpses.
He showed interest in true crime, especially cases such as Anders Breivik, Viktor Kalivoda, Jiří Straka, and Czech criminal cases in general.
Kozák’s favorite anime was the sci-fi series All You Need Is Kill, with Keiji Kiriya as his favorite character, whom he wrote about in an essay. The story centers on emotional detachment and a time loop of violence and death.
Kozák clearly had an interest in history; in therapy sessions he mentioned that studying at the Faculty of Arts was one of the few activities that brought him at least partial satisfaction and meaning in life.
His interest in history probably appeared in collecting artifacts; during a search of his home, investigators found a Nazi dagger with a swastika and the inscription “Blut und Ehre” (“Blood and Honor”), used by the Hitler Youth.

David Kozák Info – Part 2: Student Years and Early Adulthood
Student Life and University Environment:
Despite long-standing depression and thoughts of death, Kozák maintained strong academic performance.
Kozák noted that studying at the Faculty of Arts was one of the few things that gave him a sense of satisfaction and purpose.
Kozák likely chose history out of personal interest, though his focus on Polish history was never explained. He mentioned plans to continue his studies in Poland, though it is unclear whether he intended to.
He graduated with a bachelor’s degree in History and European Studies, successfully defended his thesis with an excellent grade, and received the Marian Szyjkowski Award from the Polish Institute in Prague.
At university, Kozák remained socially withdrawn. He was described by students as a quiet, unremarkable loner. Quotes: “He was a quiet guy, an introvert. He hardly talked to us”, “I vaguely remember him. He was always such an inconspicuous person who didn't interact with many people”.
Kozák spent most of his time alone at his computer after starting university. He may have lived in a student dormitory for a time, but later returned to his parents’ home during the COVID-19 pandemic.
Employment and Workplace Experience:
Kozák worked at an airport for over two years alongside his father and sister, as a terminal service assistant.
He reportedly received positive evaluations: he was responsible, diligent, had no disciplinary issues, and showed no aggressive behavior.
Mostly colleagues described him as restless, and some suspected he might be autistic, referring to his unusual behavior.
In conversations at work, he mainly talked about school, books, and work, and at times about having a firearms license or about weapons.
On one occasion, Kozák brought a long gun to the airport in an unusually large backpack and showed it to a colleague after she asked about it.
Another colleague once heard him say, “I would shoot everyone in Terminal 2”.
It was noted that he regularly worked night shifts, especially in the year leading up to the crime.
Mental Health and Deterioration:
After starting university, Kozák frequently talked to his friends about ending his life. His classmates gave him a list of contacts for help, but he did not use them. As his statements continued, his friends urged him to seek psychiatric help.
Suicidal tendencies intensified during the COVID-19 pandemic, especially from spring 2022. Kozák explained that these thoughts emerged when he had a lot of free time and experienced “boredom”.
His first psychiatric appointment, attended with a friend, took place in September 2023. In total, he had four sessions and one psychological assessment.
His friend accompanied him to the session, as she knew he would not go alone. Kozák said she seemed more concerned about his condition than he was about himself.
The sessions revealed a range of issues, including suicidal and homicidal ideation, existential loss of meaning, depression, lack of socialization, and family conflict.
After four sessions with the psychiatrist and one with another psychologist, both reported that he became withdrawn and either missed or cancelled scheduled appointments.
Kozák did not disclose having a firearms license or plans to obtain one, although he had already received it in spring 2023. He also refused to name the physician (who approved his firearm license).
Over the year preceding the crime, classmates noticed that Kozák became increasingly fatigued. He complained of insufficient sleep due to night shifts at his airport job and began eating less.
According to them, he became noticeably more stressed. For example, he started smoking more heavily. Witness quote: “What struck and somewhat surprised me was that he suddenly smoked about eight cigarettes in a row, within about fifteen minutes”.
The only person Kozák appeared close to before the crime was his female friend. In the final months, he shared his hobby: weapons, shooting ranges, optics, and long-range shooting courses.
Since at least 2023, especially in the months before the shooting, he actively searched for material on mass murder, watched documentaries about serial killers, and consumed extreme pornography.
