PHILADELPHIA (KYW Newsradio) — As police and prosecutors continue their investigation into the Levittown man accused of beheading his father and posting a gruesome video about it to YouTube, more details about the suspect’s life are coming to light. Investigators say he had a history of railing against the government and espousing conspiracies.

It wasn’t just the 14-minute YouTube video where 32-year-old Justin Mohn expressed his worldview and grievances. In a 2020 online pamphlet, he tried to make the case that there should be a “bloody revolution” against those who were born before 1991 — the year he was born. He also encouraged the killing of family members and public officials.

Mohn, a 2014 Penn State University graduate, was unsuccessful in trying to sue the federal government a few different times over his student loans, claiming mental and physical anguish over having to pay them back.

While living in Colorado in 2017, Mohn allegedly harassed employees at the Colorado Springs credit union where he once worked, threatening to sue the business for $10 million unless it agreed to a $2 million settlement. He also allegedly threatened to publish false statements about them or come to the credit union and make false statements to provoke police to attack the employees and then film it.

Three employees sought protection orders against Mohn but dropped the case under a settlement in which he promised not to contact them. As part of the case, the workers had submitted the lines from a song or poem written by Mohn that they felt was threatening, titled “Men Don’t Get No Warning Shot.”

In one email submitted as evidence, Mohn accused his co-workers of tampering with evidence in a disciplinary matter against him in 2016 and said the state’s civil rights division was investigating.

Then in 2018, he sued another employer, Progressive Insurance, claiming he was fired because he was a man who was overqualified and overeducated. The company said he was let go because he kicked open a door. A federal judge ruled that he did not have sufficient evidence to show that he was discriminated against because he was a man. An appeals court upheld the ruling.

He also espoused a variety of conspiracy theories and rants about the Biden administration, immigration and the border, fiscal policy, urban crime, and the war in Ukraine.

His father Michael, the victim, was a federal employee, which his son had indicated in his YouTube video. The elder Mohn worked for the Philadelphia District of the U.S. Army Corps of Engineers.

“We are deeply saddened to learn of the tragic death of teammate Michael Mohn,” the district said in a statement. “Our thoughts and prayers are with the Mohn family and we are focused on supporting our grieving employees at this time.”

While more information is coming to light about the suspect and the victim, some questions have yet to be answered. Middletown Township Police Chief Joseph Bartorilla was asked on Wednesday if officers had been to the Mohn family home before.

“I don’t think it’s a home we were out to all the time. Maybe over the course of the last five to 10 years, we might have been there a couple of times. But I don’t think that it’s anything that was on our radar that we needed to be on alert for,” Bartorilla said.

There is no record of Justin Mohn ever being arrested.

The exact cause of Michael Mohn’s death has also not been released. Officials said Justin Mohn had a gun on him when he was arrested at the National Guard base in Fort Indiantown Gap, Lebanon County. However, investigators did not say if the gun was used in the killing.

The Bucks County District Attorney’s Office said it will hold a press conference soon to further discuss the case.
