Terrorgram Collective Heads Linked to Slovak LGBTQ Bar Shooting Arrested
On September 6, US authorities arrested the leadership of the Terrorgram Collective terrorist group. The defendants, 34-year-old Dallas Humber and 37-year-old Matthew Allison, spent years inciting hate crimes through closed Telegram groups in the name of white supremacy and in hope of triggering a racial war. The US indictment also ties them to the terrorist attack on Zámocká Street in Bratislava, confirming findings of the Investigative Center of Ján Kuciak’s (ICJK.sk) earlier investigation from November 2022.
On October 12, 2022, the group’s leaders allegedly celebrated the Zámocká Street terrorist as the “first saint of Terrorgram” after he shot and killed two people, Juraj Vankulič and Matúš Horváth, outside Tepláreň bar, an LGBTQ place in Bratislava.
The pair from California were allegedly leaders of an international white supremacist group. As previously reported, Terrorgram consists of radical right-wing channels on Telegram where anonymous users spread neo-Nazi propaganda. The group aimed to spark a race war in the US by planning attacks on critical infrastructure and targeting “high-value” individuals. According to the FBI, the group also encouraged terrorist attacks worldwide.
The 19-year-old Zámocká Street shooter was reportedly radicalized through Terrorgram materials. He read their guides and communicated in the same groups as the now-indicted leaders. Hours before the attack outside the Tepláreň bar, he published a manifesto thanking Slovak extremist “SlovakBro”– in the meantime arrested and sentenced to six years in jail in Slovakia – and the “Terrorgram collective” for their writings and practical guides. „Building the future of a white revolution, one publication after another,” the shooter wrote.
Before the attack, the shooter also sent a 61-page manifesto to Dallas Humber, who later turned it into an audiobook. Information from Terrorgram, which ICJK.sk had access to in November 2022, supports the US indictment’s claims. A linguistic analysis suggested that the shooter may have collaborated on the manifesto with experienced radicals in the U.S.
Actively Seeking “Future Saints”
According to US investigators, the Zámocká Street shooter was actually in direct contact with Terrorgram leaders before the attack. Humber reportedly stated in a group chat that if he became a “saint,” she would narrate his book. “That’s the cost of admission, so to speak,” she added.
The audio version of his manifesto was indeed released shortly after the Bratislava shooting.
The indictment also reveals details about Terrorgram’s recruitment efforts. The two arrested US leaders allegedly worked to recruit, radicalize, equip, advise, and inspire others to carry out attacks in support of Terrorgram’s mission. They actively sought “future saints,” individuals susceptible to radicalization and committing terrorist attacks.
The indictment released yesterday by US authorities confirms the @ICJK_sk 's 2022 findings that the terrorist who murdered two young people outside an LGBTQ+ bar in Bratislava was radicalised by #Terrorgram leaders.

In March 2022, Humber wrote in a group chat that she has focused on a particular 18-year-old member. The Zámocká shooter was 18 at the time and, according to his manifesto, made the final decision to carry out the attack in May 2022.
Both Humber and Allison, now accused of running the dangerous online terrorist group, allegedly claimed credit for the Bratislava attack and celebrated the shooter as Terrorgram’s “first saint.” Information from Terrorgram two years ago indicated that members quickly began worshiping the Tepláreň Street shooter as a saint, even creating a “saint poster” for him – a common propaganda tool of Terrorgram.
In Terrorgram, attackers who commit acts in support of white supremacy or neo-Nazism are labeled as “saints”. Whether they are killed during the attack, executed after trial, or imprisoned, they are seen as martyrs.
Creating Neo-Nazi Propaganda
Humber, identified as the narrator of Terrorgram’s documentaries and audiobooks,, previously sold adult sex toys, as revealed by HuffPost in March 2023. She and Allison reportedly joined Terrorgram in 2019, becoming leaders in the summer of 2022 after one previous leader was arrested, and another became a terrorism suspect.
In May 2022, a Slovak extremist known online as SlovakBro was arrested – one of the group’s key figures who helped create Terrorgram’s content and guides. He is currently serving a six-year jail sentence in Slovakia. However, following a recent legal amendment by Robert Fico’s government, he may be eligible to serve out the rest of his sentence under house arrest, if the court approves.
The arrested US pair not only radicalized Terrorgram followers and gave them orders but also produced a documentary which glorifies racist attacks since 1968. The film, which was anxiously expected among Terrorgram followers shortly before the Bratislava attack, was eventually dedicated to the Zámocká Street shooter.
In addition to the Bratislava shooter, Terrorgram’s US leaders also allegedly inspired a man in Turkey to stab five people near a mosque, and a New Jersey man who planned an attack on an energy facility. If convicted, Humber and Allison face a maximum sentence of 220 years in prison.
