FBI Joins Levittown Beheading Murder Investigation

Update: 1 p.m. Thursday

BUCKS COUNTY, PA —The FBI has joined the investigation by Bucks County authorities in which a son faces first-degree murder charges in the death of a Levittown man Tuesday night.

"The FBI is aware of the incident and working closely with the lead agency to support their investigation," Ned Conway, a spokesman for the Federal Bureau of Investigation in Philadelphia told Patch Thursday morning.

Justin Mohn, 32, of Levittown man faces first-degree murder charges, abuse of a corpse, and possession of an instrument of crime with intent for killing his father, who was found beheaded in the bathroom of their home Tuesday night, authorities said.

Mohn posted a 14-minute video on YouTube about the crime, shouting about conspiracy theories and holding up his father's decapitated head.

Mohn's video tirade railed against the government.

In that video, the Levittown man calls for citizens to attack federal workers, kill federal law enforcement, and attack journalists. He cited the name and address of a judge and ranted about President Joseph Biden and other high-ranking federal officials. He complained about immigrants coming into the country illegally.

A snippet that remained on social media features Mohn calling his father a "traitor to the country."

The Bucks County District Attorney’s Office and the Middletown Township Police Department are investigating the homicide.

District Attorney Jennifer Schorn, Middletown Township Police Chief Joseph Bartorilla, and the Federal Bureau of Investigation will hold a news conference at 11 a.m. Friday to provide details in the arrest.

Conway would not go into specifics of the FBI's involvement, referring all inquiries to the Bucks County District Attorney's Office.

But ABC Nightly News With David Muir on Wednesday night broadcast that the FBI's involvement had to do with "extreme threats" made against high-ranking federal government officials.
