A crazed conspiracy theorist has testified that he gunned down and then beheaded his father — posting harrowing footage of his head on YouTube — because his dad was trying to stop him from becoming the next Donald Trump.
Justin D. Mohn, 33, took the stand at his trial and coldly told the court how he shot and then beheaded his 68-year-old father, Michael Mohn, a respected civil engineer with the Army Corps of Engineers.
His mother, Denice Mohn, cried in court as her son coldly described how he showed his father’s severed head in a depraved 14-minute video he posted on YouTube for likes.
“I knew something such as a severed head would not only go viral but could lessen the violence,” the killer son told the jury.
He blamed his horrific actions on his parents’ left-leaning politics — and that he believed his dad was trying to stop him from becoming a charismatic political leader like President Trump.
Mohn said he planned a “citizen’s arrest” of his dad for treason when her confronted him in his Levittown home on January 30, 2024, and that killing him was his “plan B.”
“Unfortunately, he resisted arrest,” Mohn told the court in Buck’s County, Pennsylvania.
“I unfortunately had to use deadly force.”
Still, despite admitting to shooting his dad in the head and then sharing footage online, Mohn claimed it was justified by law, suggesting his dad tried to grab his gun and kill him first.
“I would object to calling it a murder,” he told the court, pleading not guilty to first-degree murder.
Mohn’s sickening 14-minute YouTube video was live for several hours before it was taken down.
He was arrested later the same day after climbing a fence at Fort Indiantown Gap, where he was trying to incite others to join him in trying to overthrow the US government.
Instructions for making homemade bombs, information on public officials, and numerous searches for how to incapacitate people, along with blueprints for federal buildings and documents with names such as “battle plans,” were found on Mohn’s devices, Bucks County Detective Eric Landamia told the jury.
Mohn’s defense attorney, Steven Jones, claimed his client was a known fiction writer, which is why the searches were found on his devices.
His trial resumed on Thursday, when closing arguments are expected.
