Dallas Humber, 35, of Elk Grove, Calif. — identified by federal prosecutors as a leader of the Terrorgram Collective, a transnational white supremacist terrorist group — was sentenced Friday to 30 years in federal prison for soliciting hate crimes, soliciting the murder of federal officials, and conspiring to provide material support to terrorists.
U.S. District Judge Dena Coggins imposed the 360-month sentence in federal court.
According to court documents, prosecutors say Humber served as a leader of the Terrorgram Collective — described as a white supremacist transnational terrorist group — from July 2022 through September 2024.
Authorities allege that Humber and other members used online channels to recruit and incite would-be attackers, urging them to carry out hate crimes, attacks on critical infrastructure, and assassinations, while providing what investigators described as technical instruction, encouragement, and operational guidance intended to help individuals plan and execute violence.

Investigators say people influenced by the group carried out attacks or advanced plots in the United States and abroad.
In the United States, court records describe alleged plans to attack an energy facility in New Jersey, to bomb an energy facility in Tennessee, and to kill two people in Wisconsin as part of a broader plot to assassinate a federal official. Abroad, authorities cite an alleged attempt to assassinate an Australian official.
Court documents also link the group’s rhetoric and direction to violence overseas, including the 2022 shooting at an LGBT bar in Bratislava, Slovakia, that left two people dead; a 2022 school shooting in Aracruz, Brazil, that killed four; and a stabbing outside a mosque in Eskişehir, Turkey, that injured five.
The investigation was led by the FBI’s Sacramento field office, with assistance from domestic and international law enforcement agencies, according to officials.
