A man accused of beheading his father in suburban Philadelphia posted a gruesome video on social media that shows him holding up the severed head and railing against the government, authorities said Wednesday.
Justin Mohn, 32, who is charged with first-degree murder and abusing a corpse, was armed and had jumped a fence at a National Guard facility about 100 miles (160 kilometers) away when he was arrested late Tuesday, hours after the killing, a Guard spokeswoman said.
The father, identified as Michael F. Mohn, was found decapitated in the bathroom of the home in Levittown where his son also lived.
The YouTube video, more than 14 minutes long, showed Justin Mohn picking up the head and identifying his father by name. Police said it appeared he was reading from a script as he encouraged violence against government officials and called his father a traitor to his country.
Michael Mohn was a federal employee, an engineer with the geoenvironmental section of the U.S. Army Corps of Engineers Philadelphia District.
“We are deeply saddened to learn of the tragic death of our teammate Michael Mohn. … Our thoughts and prayers are with the Mohn family and we are focused on supporting our grieving employees at this time,” the district said in a statement. It referred any further questions to law enforcement.
Police said Michael Mohn’s wife, Denice Mohn, arrived home and found the body about 7 p.m. Tuesday. Officers found the body, a machete and bloody rubber gloves, according to a police affidavit. Denice Mohn told police her husband’s white Toyota Corolla and her son were missing.
In a statement, YouTube said the video, which was uploaded and not livestreamed, was removed for violating its graphic violence policy and Justin Mohn’s channel was shut down. Police said the video was online for about five hours.
Mohn, who also was arrested on a weapons possession charge, was arraigned Wednesday and held without bail with a hearing scheduled for Feb. 8. Police and prosecutors were expected to release additional details at a news conference Friday.
An attorney for Mohn wasn’t listed in court records, and a message seeking comment on his behalf was left at a phone listing for him. The district court office said it had no record of a lawyer representing him.
Mohn embraced violent anti-government rhetoric in writings he published online going back several years. In August 2020, Mohn published an online “pamphlet” in which he tried to make the case that people born in or after 1991 — his birth year — should carry out what he termed a “bloody revolution.” He also complained at length about a lawsuit that he lost and encouraged assassinations of family members and public officials.
