Justin Mohn, the Middletown Township man who killed his father last month and called for violent attacks against members of the federal government, was formally arraigned on Friday, Oct. 4, 2024.

Prior to the arraignment before Common Pleas Judge Stephen A. Corr, the Bucks County District Attorney’s Office filed notice of aggravating circumstances in the murder case against Mohn, preserving the prosecution’s right to pursue the death penalty should he be convicted of first-degree murder.

The filing listed the aggravated circumstance as the defendant committing the killing during the commission of a felony. His next court date is scheduled for later this month.

Mohn, 32, of the 100 block of Upper Orchard Drive, is charged with first-degree murder for killing his father Michael F. Mohn.

He 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.

Hours after the murder, Mohn was arrested at the National Guard Training Center in Fort Indiantown Gap, Lebanon County. 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.

This case was 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.

This case is assigned for prosecution to First Assistant District Attorney Edward Louka, Deputy District Attorney Ashley C. Towhey and Deputy District Attorney Christine Sassane.
