The perpetrator was identified as 19-year old
Juraj Krajčik (28 July 2003 — 13 October 2022). The day prior to the attack, Twitter account
NTMA0315 owned by Krajčík, published statements including "I have made my decision", "it will be done" and "Race First. Always". It also posted links to an original
manifesto with extremist far-right
anti-semitic,
homophobic and
transphobic views. In addition to Twitter, the murderer also posted his pictures on
4chan. His Twitter account had been suspended by the time the perpetrator's body was discovered. In addition to Heger, the manifesto mentioned other politicians as targets, including former Minister of Education
Branislav Gröhling and opposition leader and former Prime Minister
Robert Fico. According to Matej Medvecký, a counter-extremism expert, the murderer had also been active in
Terrorgram communities and subscribed to the ideology of
militant accelerationism, supported by terrorist groups such as
Atomwaffen Division.
Manifesto Just a few hours before the attack, links to a 65-page long manifesto were posted on Twitter. In the document, the author does not provide their name, claiming it is not of importance and "will be known later anyway", but identifies himself as a man of Slovak origin born on 28 July 2003, who has decided to "execute an operation" against "the enemies of the white race". The manifesto
blames Jews and
LGBT people for "causing harm to white people" and celebrates far-right murderers, including
Anders Breivik,
Brenton Tarrant and
John Earnest. The text also attributes
COVID-19 pandemic and
vaccination measures to a "Jewish plot to train the white race to be obedient" and
denies the Holocaust. It also glorifies a 22-year-old Slovak man in particular, known on
Telegram as
Slovakbro, who was arrested by the police in May 2022 for promoting right-wing extremism and calling for the overthrow of the democratic system in Slovakia by means of sabotage and terrorism. The
Telegram group known as
Terrorgram was mentioned in his manifesto, and credited with "Building the future of the White revolution, one publication at a time." == Aftermath ==
