A preliminary hearing for Justin Mohn, the Middletown Township man who killed his father last month and posted a disturbing YouTube video holding his father’s decapitated head and calling for violent attacks against members of the federal government, was held Tuesday, Sept. 10, 2024, at the Bucks County Justice Center.

After two hours of testimony, Mohn, 32, of the 100 block of Upper Orchard Drive, was ordered held for trial for the Jan. 30 killing of his father Michael F. Mohn. Magisterial District Judge Charles D. Jonas scheduled Mohn to be formally arraigned on Oct. 11.

In addition to first-degree murder, Mohn is also charged with two counts each of terrorism and possession of an instrument of crime, and one count each of robbery, firearms not to be carried without a license, theft by unlawful taking, receiving stolen property, criminal use of a communication facility, terroristic threats, defiant trespassing, and abuse of a corpse.

Michael F. Mohn, 68, was killed on Jan. 30 inside his home at 145 Upper Orchard Drive. An autopsy found that the victim was shot in the head before he was decapitated using a machete and knife.

During their investigation, detectives learned that the victim’s adult son, Justin Mohn fled the location in the victim’s 2009 Toyota Corolla.

Police later received information about a 14-minute video posted to YouTube, which showed Justin Mohn picking up the decapitated head of his father, identifying him by name and as his father.

In the video, Justin Mohn ordered all militia and patriots across the United States to kill all federal employees. His father was a federal employee with the Army Corps of Engineers.

Mohn also listed specific federal officials who should be captured and publicly executed, including giving the name and address of a U.S. District Court Judge as one of his targets.

Portions of the video were played at Tuesday's preliminary hearing.

Hours after the murder, investigators tracked Mohn’s cellphone to the National Guard Training Center in Fort Indiantown Gap, Lebanon County. There, he climbed a barbed wire fence and entered a secure military installation.

The investigation revealed that Justin Mohn went to Fort Indiantown Gap in an effort to mobilize the National Guard to raise arms against the federal government.

Justin Mohn was taken into custody by the Fort Indiantown Gap Police Department and Pennsylvania State Police. He was in possession of a loaded Sig Sauer 9mm pistol.

This case is being investigated by Detectives with the Bucks County District Attorney’s Office and the Middletown Township Police Department, with assistance from the Federal Bureau of Investigation, the Fort Indiantown Gap Police Department, and Pennsylvania State Police.
