Sister of Army engineer allegedly beheaded by son shares shock at ghastly crime: ‘We can’t believe it’
An aunt of Justin Mohn, the conspiracy theorist accused of beheading his father and flaunting his head on a YouTube video, has said her family is in complete shock at the gruesome murder of her brother.
“It’s unbelievable. It’s very fresh,” Mary Jasch told the Daily Mail of the decapitation of her 68-year-old brother, Michael Mohn, at his Levittown home Tuesday.
“We can’t believe it,” Jasch said of her family’s reaction.
“I can’t even think what [Michael’s] wife is going through,” she said of her sister-in-law Denice Mohn, who stumbled across the headless body Tuesday.
“No one can believe it.”
Her brother had worked for the Army Corps of Engineers as a geo-environmental engineer serving the Philadelphia area for over two decades before he was allegedly killed by his son — who proclaimed in a YouTube video that his dad was “a federal employee of over 20 years” as he held up his bloody head for all to see.
In a statement, the Army Corps said it was “deeply saddened to learn of the tragic death of our teammate Michael Mohn.
“Our thoughts and prayers are with the Mohn family as we are focused on supporting our grieving employees at this time.”
Justin was arrested in his father’s death Tuesday evening, and was pictured smirking in his mugshot as he was charged with first-degree murder, abuse of a corpse, and possessing an instrument of crime with intent to kill.
His mom, Denice Mohn, had called the cops around 7 p.m. after finding her husband’s headless body with “a large amount of blood around him,” according to court documents obtained by Levittown Now.
“Officers also located the deceased male’s head inside of a plastic bag which was inside of a cooking pot in a first-floor bedroom next to the bathroom,” Middletown Township police and Bucks County Detectives wrote in court papers filed Wednesday morning.
A machete and a large kitchen knife were found in the bathtub, and bloody rubber gloves in a first-floor bedroom, police said.
As police investigated the brutal murder, they received a tip about a 14-minute long YouTube video — seen by The Post before it was deleted — in which Mohn lifted up a severed head in a bloodied plastic bag, claiming it was his father’s.
“He is now in hell for an eternity as a traitor to his country,” Mohn said, before going on an unhinged rant against the government in line with QAnon conspiracy theories, calling for “militias” across the US to unite and kill federal officials “on site.”
The video, titled “Mohn’s Militia – Call to Arms for American Patriots,” was posted to YouTube around 5:30 p.m. and appears to have been recorded in a bedroom where Mohn seems to be reading from a written manifesto on his computer screen.
In the footage, Mohn claims he is the commander of America’s network of militias as he rants against migrants, the Biden administration, the LBGTQ community, Black Lives Matter and “far-left woke mobs,” while calling for the slaughter and public execution of FBI agents, IRS employees, US Marshals, federal judges, border control officers and more “for betraying their country.”
He was later located carrying a gun and wandering around the Fort Indiantown Gap complex, a sprawling campus more than 100 miles from the home where he is accused of killing his dad, a state Department of Military and Veterans Affairs spokesperson confirmed to The Post.
Mohn was then arrested without incident, and Middletown Police Chief Joe Bartorilla told the victim’s wife to notify Mohn’s siblings “before they see the video or the video is sent to them,” according to the Bucks County Courier Times.
“We’re getting contacted by some people in the community that know us, and know him and his family,” Bartorilla said. “And we’re hearing a lot. Obviously, he’s well known in the community just by the calls we’re getting.”
Neighbors said they noticed the younger Mohn began to exhibit strange behavior over the summer.
“He just started acting funny,” Bart DeHaven told 6ABC.
“I made a couple calls to the police department because he was sitting right there… staring at my house constantly. I thought, ‘that’s kind of strange.’”
DeHaven said he did not feel threatened by Mohn’s behavior “but it’s just weird for somebody to stay seated right there, stare straight at my house.
“You know, when I would come home he would just pick up and move,” DeHaven noted, calling the behavior “weird.”
In private, though, Mohn would share unhinged content online — including songs and books about Satan, stalkers and corrupt presidential candidates.
He once even wrote a pamphlet entitled “America’s Coming Bloody Revolution,” in which he suggested he would have to kill family members in an “inevitable” violent revolution.
“Americans will have to weigh what is worse — allowing themselves to lose freedom and independence or killing their own family members, teachers, coworkers, bosses, judges, elected leaders and other older generations,” he wrote.
Mohn also filed at least three lawsuits against federal agencies, including the US government, over his student loan debts.
In one, he claimed the US government “negligently and fraudulently” pushed him to take out student loans between 2010 and 2014 to pay for his education at Penn State University.
He alleged he should have been warned that his degree in agribusiness management would have been worthless in securing a job because he was an “overeducated white man.”
Mohn was arraigned at 4 a.m. Wednesday and denied bail, according to a court docket. He is scheduled for a hearing on Feb. 8.
