According to the Anti-Defamation League, Atomwaffen - German for 'atomic weapon' - cells have been "reported in multiple states, including Colorado, Florida, Illinois, Pennsylvania, Texas, Massachusetts, Washington, and Wisconsin." The group's "vile propaganda often promotes violence against minority communities, including LGBT people, Jews, Muslims, and African Americans." And although experts say there may be only 80 members in the organisation nationwide, Bernstein's death is the third high-profile killing connected to Atomwaffen in the last year. Woodward is scheduled to be arraigned in a US court this week. He has not yet entered a plea, and his attorney has not commented on the ProPublica report.

"Joining us means serious dedication not only to the Atomwaffen Division and its members, but to the goal of ultimate uncompromising victory. With this means only those willing to get out on the streets, in the woods, or where we maybe [sic] in the world and work together in the physical realm," the website says. "We often go hunting, adventuring, and a group favourite is urban exploring." A video on what appears to be a YouTube channel affiliated with the group captures footage from a "Doomsday Hatecamp," including images of members burning the US Constitution, hiking the woods and pouring drinks out "for the martyrs now and the martyrs yet to come." "Atomwaffen members have a macabre fascination with serial killer Charles Manson and his vision of a race war between whites and blacks," the Anti-Defamation League reported. "For this reason, in 2017... Atomwaffen members sought out neo-Nazi Manson devotee and former American Nazi Party member, James Mason, and republished some of his writing, including Siege, a book based on a collection of newsletters Mason wrote in the 1980s."

The group first surfaced in the mainstream in May 2017 when police in Tampa arrested 18-year-old Devon Arthurs for allegedly killing two of his roommates, 22-year-old Jeremy Himmelman and 18-year-old Andrew Oneschuk. As The Washington Post reported, Arthurs later told police "all of them had been friends with a common neo-Nazi belief." Arthurs, however, converted to Islam and killed his roommates, later telling Tampa police Himmelman and Oneschuk were planning terrorist attacks, including the bombing of a South Florida nuclear power plant. ProPublica reported all three were affiliated with Atomwaffen Division. A fourth roommate, Brandon Russell, was also arrested. According to a federal criminal complaint, Arthurs told law enforcement Russell had "threatened to kill people and bomb infrastructure." A search turned up an explosive substance in a cooler at the property. Russell admitted he had manufactured the explosive substance, and also told police he was a neo-Nazi who belonged to the "Atom Waffen." The Tampa Bay Times reported that Lyssa Himmelman, the sister of one of the dead roommates, dismissed claims the four men were neo-Nazis as "lies." She described her brother as "a wonderful guy with a good heart." Russell pleaded guilty to illegal possession of explosives. He was sentenced to five years in prison. Despite confessing to the killings at first, Arthurs had pleaded not guilty. ProPublica reported that he is currently undergoing a psychiatric evaluation to see if he is fit for trial.

The Atomwaffen is also linked to the bizarre murder of Scott Fricker, 48, and Buckley Kuhn-Fricker, 43 in their Reston, Virginia, home last December. As The Washington Post reported in January, the couple had been pushing their teenage daughter to break up with her 17-year-old boyfriend after discovering his Nazi beliefs on social media. Police say the boyfriend then killed the parents and turned the gun on himself. He survived but remains in a critical condition. Two months before the shooting, the teenager allegedly mowed a 12-metre swastika into a community field's grass. He has been charged as a juvenile with two counts of murder. HuffPost tracked down the suspect's Twitter account, where he shared Atomwaffen Division posts, including material on James Mason's reprinted Siege book. Washington Post
