BOISE, Idaho — Federal agents have arrested a Boise man, Matthew Allison, 37, identified as a leader of “Terrorgram Collective,” a white supremacist terrorist group operating across multiple countries, according to the U.S. Attorney’s Office. A co-leader, Dallas Humber, 34, from Elk Grove, California, was also taken into custody.
Both were charged with orchestrating a campaign of hate from behind their screens, using the social media platform Telegram to plan and solicit terrorist attacks aimed at inciting a race war. The charges against them include multiple counts of soliciting murder and hate crimes, as outlined in a recent indictment.
This indictment reveals that Allison and Humber shared instructions on constructing explosives and produced white supremacist propaganda. They also allegedly pinpointed potential high-profile assassination targets, including U.S. senators and judges.
Their actions have been linked to several violent incidents abroad, including a stabbing outside a Turkish mosque and a deadly shooting at an LGBTQ+ bar in Slovakia. Other plans reportedly targeted energy facilities in New Jersey.
The U.S. Attorney’s Office for the Eastern District of California stated that the pair face the possibility of up to 220 years in federal prison if convicted.
