An agitated conspiracy theorist accused of beheading his father and then lifting his head in a sickening online video shot him to death with a gun he had legally purchased the day before, authorities said Friday.
Justin Mohn, 32, bought a 9mm Sig Sauer handgun Monday at a store a few miles from his home in Levittown — legally obtaining the gun, District Attorney Jennifer Shawn said. This was just hours after he surrendered his medical marijuana card.
The next day, Sean posted a rambling video on YouTube of him shooting his 68-year-old father, Michael Francis Mone, in the head, then decapitating him with a knife and machete, and lifting his head wrapped in plastic, Sean said. Told.
Officials said Mohn’s mother returned home Tuesday afternoon to find her husband’s headless body in the house, with the head placed in a pot.
The suspect was arrested that night after infiltrating a National Guard facility about 100 miles away — he was there to “mobilize the National Guard to procure weapons against the federal government,” Schon said. He claimed that.
He allegedly still had the handgun, but the one bullet he used to shoot his father was missing.
Prosecutors said it was “horrifying” that the footage of the father’s head being lifted remained on the internet for several hours and was viewed by at least 5,000 people before it was pulled up.

The video “reveals that he had a clear mind about his purpose and actions, regardless of his beliefs,” Sean said, adding that the suspect had no history of mental illness. He said there was no such thing.
Sean declined to comment on the motive for the brutal murder. But she said her rambling 14-minute video includes threats to target and capture all federal employees, and even shares a federal judge’s address and offers a bounty on him. He pointed out that the content was
Mr. Mone said his father, who worked as an engineer in the geological and environmental division of the U.S. Army Corps of Engineers, Philadelphia District, was “in hell for being a traitor to our country,” Mr. Sean said.
He also supported various conspiracy theories. He calls himself the commander of America’s militia network and calls himself a commander in chief for FBI agents and the I.R.S., while ranting against immigrants, the Biden administration, the LBGTQ community, Black Lives Matter, and the “woke mob of the far left.” called for a massacre and public execution. Officers, federal marshals, federal judges, Border Patrol agents and others “betrayed their country.”
Mohn was seen grinning in a mugshot when he was arraigned early Wednesday morning.
A woman who answered the phone at the Bucks County Public Defender’s Office said Friday that they were representing him and that the office declined further comment.
