A 32-year-old man in Pennsylvania posted a video on YouTube this week where he picked up a clear plastic bag containing the severed head of his father and held it in front of the camera.
“This is the head of Mike Mohn, a federal employee of over 20 years, and my father,’ Justin Mohn said in the now-deleted video reviewed by WIRED. “He is now in hell for eternity as a traitor to his country.”
Over the course of the next 14 minutes, he ranted about a myriad of far-right talking points and conspiracies including Black Lives Matter, taxes, the LGBTQ community, and the Biden administration. He also urged viewers to kill all federal employees and seize federal offices, while railing against “far-left woke mobs.” He claimed to be the head of an American militia network known as Mohn’s Militia. “I am now officially the acting President of America under martial law,” he said.
But there was one issue that he focused on more than any other: migrants along the southern US border.
“The federal government of America has declared war on the American citizens and the American states,” the man says. “America will be less protected when the fifth column of illegal immigrants strikes Americans on our own soil.”
He also made demands that the US close its borders to immigrants and for “the mass deportation of the millions of illegal immigrants who have entered the country under the Biden regime, which has put Americans in direct harm.”
Over the last few weeks, right-wing rhetoric around a so-called migrant invasion reached new heights as the standoff between Texas governor Greg Abbott and President Joe Biden’s administration over the removal of razor wire on the Texas-Mexico border has continued. A convoy of far-right extremists is driving to the border and Republican politicians around the country have come out in support of Abbott.
Multiple researchers tell WIRED that the events and rhetoric surrounding the Texas-Mexico border could be linked to the violent video Mohn posted this week. This border controversy and the incendiary rhetoric surrounding it appeared to be something that deeply angered Mohn, highlighted by his YouTube video and the rest of his extensive online footprint of books, pamphlets, music and social media posts, many of which are steeped in far-right conspiracies. In a 2020 essay entitled “America’s Coming Bloody Revolution” Mohn claims a violent revolution against the government is not only necessary and will succeed.
“For individuals in this conspiratorial mindset who have been subjected to countless hours of extremist narratives and grievances, every new flashpoint—from the Texas border crisis to the Israel/Hamas war to Taylor Swift—is evidence that their worldview is the reality,” Jon Lewis, a research fellow with the Program on Extremism at George Washington University, tells WIRED. “This act of violence represents the threat posed by mainstreaming hateful and dehumanizing rhetoric.”
“I listened to his diatribe about twenty times to write it all out and there is zero doubt in my mind that he was influenced by the recent events involving Texas,” Caroline Orr, a behavioral scientist and postdoctoral researcher at the University of Maryland who tracks extremism online, wrote on X (formerly Twitter). “This was expected and there will be others.”
Investigators have not mentioned a motive for the alleged decapitation, but Mohn was formally charged early Wednesday morning with first-degree murder, abuse of a corpse, and possession of an instrument of crime with intent. Police said in a statement posted to Facebook that they were alerted to the incident when Mohn’s mother called 911 and said she had come home to find her husband’s decapitated body on the floor of their bathroom. Mohn was arrested 100 miles away on Tuesday evening when he was discovered armed and wandering around a Pennsylvania National Guard training center at Fort Indiantown Gap, AP reported.
Multiple experts believe that extremism and conspiracy theories could still be at the root of what happened. “Some have been quick to write Mohn off as mentally unwell and while this may be accurate, this incident illustrates the threat of anti-government extremism and conspiracy theories, which have become all too common since the 2020 election,” Katherine Kenealy, the head of threat analysis at the Institute for Strategic Dialogue, tells WIRED. “He was so steeped in anti-government beliefs that he not only viewed his father as a ‘traitor’ because of his purported job, but selected him as a target because of it. “
Following the alleged murder, far-right figures immediately began boosting conspiracies about the beheading being a false flag in favor of the Democrats—something that has virtually become a reflex action among far–right figures following major news.
One of the main narratives shared was a claim that the Democrats were behind the incident as a way of boosting support for the Preventing Private Paramilitary Activity bill which is currently making its way through Congress. One of those pushing this narrative was Laura Loomer, a close ally of former President Donald Trump.
“Justin Mohn sure looks like the perfect Democrat Patsy for the sake of demonizing people who call out the invasion on the border, and for the sake of getting support to ban militia,” Loomer wrote on X, adding: “Just another ‘coincidence.’”
“False flag and ‘psyop’ conspiracy theories have rapidly spread online since the incident,” Kenealy tells WIRED. “These narratives detract from the severity of the incident and attempt to minimize the threat posed by anti-government ideologies.”
But despite a long history of expressing his disturbing views on platforms like Reddit, Facebook, Twitter, as well as publishing music on YouTube, Spotify, and Deezer, experts say that it would have been virtually impossible to identify him as a threat before his alleged beheading of this father this week.
“It’s more or less impossible to track this stuff in advance most of the time,” Orr tells WIRED. “We can make an educated guess about what will happen when politicians are putting out inflammatory rhetoric that has incited violence previously, but it’s extremely hard to identify who is going to be the one who responds to the ‘call.’”
As the convoy heads towards the border and rallies are organized in Eagle Pass, Texas and Republican lawmakers, including former President Donald Trump, continue to push violent rhetoric. These kinds of actions, experts say, could lead to potential violence.
“It’s hard to determine when acts of violence like this will occur, but given the panic being spread about the border, it’s highly likely that more will act on these narratives,” Samantha Kutner, an extremism researcher and CEO of counter terrorism company GlitterPill LLC, tells WIRED. “Not everyone who gets exposed to conspiratorial worldviews and beliefs and theories about the border wall engages in violence, but the proliferation of disinformation and conspiracy theories does impact certain subsets of the population who are perhaps more vulnerable to that messaging than others.”
