This story has corrected the name of the victim’s wife to Denice Mohn, not Denise Mohn.

A man accused of beheading his father in suburban Philadelphia and posting a gruesome video on social media that shows him holding up the severed head has been charged with first-degree murder and abusing a corpse, authorities said Wednesday.

Justin Mohn was armed and had jumped a fence at a National Guard facility about 100 miles (161 kilometers) away when he was arrested late Tuesday, hours after the killing, a Guard spokeswoman said.

The father, identified as Michael Mohn, was found beheaded in the bathroom of his home in Levittown, where court records said his 32-year-old son also lived. Police said Justin Mohn was taken into custody at Fort Indiantown Gap.

Police said Michael Mohn’s wife, Denice Mohn, arrived home and found the body about 7 p.m. Tuesday. Officers found Mohn’s body and bloody rubber gloves, according to a police affidavit. Denice Mohn told police her husband’s white Toyota Corolla and her son were missing.

Police said the YouTube video, which was more than 14 minutes long, showed Justin Mohn picking up his father’s decapitated head and identifying him by name. Police said it appeared Mohn was reading from a script as he railed about the government.

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 wrongful termination lawsuit that he lost, and encouraged assassinations of family members and public officials.

In the video posted after the killing, he described his father as a 20-year federal employee and called him a traitor to his country. 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.

Mohn was driving his father’s car when police took him into custody, Capt. Pete Feeney of the Middletown Township Police Department said. Officials at Fort Indiantown Gap were told late Tuesday that Mohn’s cellphone had pinged nearby, according to Angela Watson, communications director for the Pennsylvania Department of Military and Veterans Affairs.

Investigators caught up with Mohn inside the National Guard base, where he was walking after having apparently jumped the fence. He had a gun when he was caught, Watson said. She said he has never been a member of the Pennsylvania National Guard.

The house where the body was found is in a suburban development of single-family homes. No one answered the door there early Wednesday.

Neighbors out walking dogs Wednesday morning described Justin Mohn as a regular walker in the development, someone they recognized and described as weird.

Bart DeHaven said he called police a handful of times since the summer after Justin Mohn sat on a raised manhole cover in a park directly across the street from his home and stared at his house.

“It’s just sad,” DeHaven said. “He should have got some kind of help.”

Carrie McCarthy said she saw him walking frequently and sitting in the wooded area in the neighborhood. She said someone sent her the YouTube video, which left her stunned.

“I screamed. I totally screamed,” she said. “I opened the video and I was like, ‘Oh my God, that’s they guy I see every day, and I knew something was unhinged.’”

Mohn, who also was arrested on a weapons possession charge, was arraigned early Wednesday and held without bail. He is scheduled for a hearing on Feb. 8. A spokesperson for the Bucks County district attorney’s office said they did not expect to comment publicly about the case Wednesday.

An attorney for Mohn wasn’t listed in court records Wednesday morning and a message seeking comment on his behalf was left at a phone listing for him. The court clerk’s office said it had no record of a lawyer representing him.
