Suspect accused of killing and beheading father bought gun the day before, prosecutor says

DOYLESTOWN, Pennsylvania –

The man accused of beheading his father in his Northeast Philadelphia home and posting a video of the severed head online shot him for the first time with a gun he bought the day before, the county prosecutor said Friday.

Bucks County District Attorney Jennifer Schorn said at a news conference in Doylestown that Justin D. Mohn had a “clear mind” when he allegedly killed his father Tuesday before driving about two hours to a training facility. of the Pennsylvania National Guard, where he was found with a gun and detained. An autopsy showed that the man’s father, Michael Mohn, had been shot in the head before being decapitated with a knife and machete, he said.

Justin Mohn, 32, adopted violent anti-government rhetoric in writings he posted online several years ago. He had no history of being committed for mental illness and purchased the 9mm handgun legally, Schorn said, providing a medical marijuana card before the purchase so he would be eligible to purchase the gun.

“It was evident to us that he was clear-minded about his purpose and what he was doing, regardless of his beliefs,” Schorn said.

A woman who answered the phone at the Bucks County Public Defender’s Office said Friday that they were representing him and said the office declined further comment.

Middletown Township Police Chief Joe Bartorilla said Friday that Justin Mohn’s former employer called police last year over concerns about his writings and asked for legal assistance to terminate his employment, which police said his department did not. could provide.

Justin Mohn was arrested Tuesday night at Fort Indiantown Gap, where he hoped to “mobilize the Pennsylvania National Guard to take up arms against the federal government,” the prosecutor said.

Justin Mohn’s mother discovered her husband’s remains in the Levittown home where the three lived together and went to a neighbor’s house to ask them to call police, Schorn said.

Justin Mohn’s video, which YouTube removed after several hours, included rants about the government, a topic he also embraced with violent rhetoric in writings posted online dating back several years.

Schorn said authorities took possession of the video but expressed concern about the hours it remained online.

“It’s pretty horrifying how many views we know it got before it was removed,” he said.

Michael Mohn worked as an engineer in the geoenvironmental section of the Philadelphia District of the U.S. Army Corps of Engineers.

Justin Mohn faces charges of first-degree murder, abuse of a corpse and possession of criminal instruments. He is being held without bail.

In the YouTube video, Justin Mohn grabbed his father’s head and identified him. Police said it appeared he was reading a script in which he encouraged violence against government officials and called his father a 20-year-old federal employee and a traitor. He also embraced a variety of conspiracy theories and rants about the Biden administration, immigration and borders, tax policy, urban crime and the war in Ukraine.

Police said Denice Mohn arrived home in the suburb of Levittown around 7 p.m. Tuesday and found her husband’s body, but her son and a vehicle were missing. According to a police affidavit, a machete and bloody rubber gloves were at the scene.

In August 2020, Mohn wrote that people born after 1991 (his own birth year) should carry out a “bloody revolution.”

Mohn allegedly drove his father’s car to Fort Indiantown Gap in central Pennsylvania and was arrested. Cell phone signals helped locate him, according to Angela Watson, communications director for the Pennsylvania Department of Military and Veterans Affairs.
