Justin Mohn: How Right-Wing Radicalization Led to Father's Beheading

On January 30, 2024, 68-year-old Michael Mohn, a civil engineer with the U.S. Army Corps of Engineers, was shot and beheaded in his Levittown, Pennsylvania home by his 33-year-old son Justin Mohn. The murder investigation revealed forensic evidence including a Sig Sauer 9mm pistol purchased 24 hours before the killing, a notebook containing detailed plans labeled "Boom" and "Slice," and online search history going back at least five years showing research on handgun purchases, bullet penetration of skulls, and explosive-making instructions. Justin then uploaded a 14-minute YouTube video titled "Mohn's Militia - Call to Arms for American Patriots" where he held up his father's severed head twice, declared himself "Acting President," leaked a federal judge's home address, and called for the execution of all federal employees.

Justin Mohn became the first person ever convicted under Pennsylvania's terrorism statute. His years-long radicalization into right-wing extremism involved four failed lawsuits against the Department of Education over student loans, self-published manifestos calling for government overthrow, and research on domestic terrorist Timothy McVeigh. After the killing, he drove 100 miles to a National Guard base carrying explosive recipes on a USB drive, believing soldiers would join his revolution. In July 2025, he received two consecutive life sentences without parole. Prosecutors revealed his online history showed he'd been planning violence for at least five years.
