Neighbors of Justin Mohn, who beheaded his father, say he was ‘acting strange’ and smoking marijuana heavily before the gruesome murder

Neighbors of the Pennsylvania man accused of killing his father before showing off his severed head in a YouTube video have described him as “unhinged” in the months leading up to the gruesome murder.

Justin Mohn, 32, now faces charges after allegedly beheading his father, 68-year-old Michael Mohn, at the family’s Levittown home on Tuesday.

“There was something wrong with him,” Carrie McCarthy told WPVI-TV. She said she clicked on the 14-minute video and screamed.

“He’s a fixture in the neighborhood,” McCarthy continued. “He just walked around and always had his water bottle with him. And he would stop at random places and just light up a joint and just start smoking.”

Another neighbor, Bart DeHaven, said Mohn started acting “funny” over the summer — to the point where he called authorities.

A neighbor, Carrie McCarthy, said Mohn would often walk around the neighborhood and “light up a joint and just start smoking.”

“I called the police station a few times because he was sitting there on that sewer thing and staring at my house all the time,” DeHaven explained. “I thought that was strange.”

The neighbor denied ever feeling threatened.

“But it’s just weird for someone to sit there and stare straight at my house. You know, I would come home and he would just pick up and move,” he said.

Mohn was apprehended Tuesday evening about 100 miles from the family home by a National Guard base at Fort Indiantown Gap. He was charged with first-degree murder.

Hours earlier, his mother discovered the headless body and called police.

Mohn’s father worked for the US Army Corps of Engineers Philadelphia District and was branded a “traitor to the country” in his son’s extensive manifesto video.

‘It’s unbelievable. It’s very fresh. We can’t believe it,” Mary Jasch, the victim’s sister, told DailyMail.com.

“I can’t even imagine what his wife is going through. No one can believe it.’

Mohn’s mother, Denice, told police she left the house around 2 p.m. Her husband and son were the only ones home at the time of the murder.

Police discovered Michael’s severed head in a plastic bag placed in a cooking pot in a bedroom.

In the bathroom next door, investigators retrieved a large kitchen knife and a machete from the tub. Bloody rubber gloves were also found in a first-floor bedroom.

Angela Watson, communications director for the Pennsylvania Department of Military and Veterans Affairs, told DailyMail.com that Mohn’s cell phone was pinged while he was traveling around the state.

As Middletown police rushed to arrest him at the military base, they warned nearby businesses to lock their doors, she said.

“He was subsequently located outside the facility, where officers discovered his vehicle, but he was not inside,” Watson continued.

“There was another ping at the facility and at that time the State Police were notified. Mohn was found walking with the installation on one of the main roads and taken into custody without incident.”

Watson added that he had a firearm with him.

Fort Indiantown police were notified of his presence in the area at 9 p.m. The 32-year-old was arrested shortly afterwards and held in a cell overnight before being transferred to the Middletown Police Department.

The neighbor said Mohn sat across from his house and stared at it “constantly,” but admitted he never felt threatened other than finding the behavior “weird.”

In the gruesome YouTube clip, Mohn briefly discussed his motivations behind his father’s murder before launching into a long-winded rant against the government.

As the camera rolled, he held up his father’s severed and bloodied head, wrapped in plastic.

“This is the head of Mike Mohn, a federal employee for over 20 years… and my father,” Mohn said. “He is now in hell forever as a traitor to his country.”

The University of Colorado graduate called himself “the commander of America’s national network of militias, which you may know as Mohn’s Militia.”

In the following minutes he frequently referred to God and Satan and called on people to follow him.

“Before the 2020 presidential election, some voters and campaign workers from both the Republican and Democratic parties saw me as the best candidate for president of America, despite my age,” Mohn said.

He claimed he “could have been the first unanimously elected president since George Washington.”

The 32-year-old railed against “socialists, globalists and communists” and accused the federal government of “woke mobs” who were “destroying the country.”

Mohn said he was offering a $1 million reward to anyone who could kill officials, including FBI Director Christopher Wray, Attorney General Merrick Garland and former Attorney General Bill Barr.

The Pennsylvania man previously filed a lawsuit against the United States after he failed to secure a job.

According to court documents filed in 2023, Mohn argued that he deserved more than $10 million from the United States because his degree “did not lead to better jobs or higher wages, but rather disadvantaged him because he was perceived as an “overeducated white male.” ‘ and ‘affirmative action’ policies are harming his career prospects.’
