MIDDLETOWN TOWNSHIP, PA — Justin Mohn, 33, was convicted of first-degree murder and related offenses and was sentenced to life in prison without parole on Friday, July 11, 2025, for the brutal murder and beheading of his father, Michael Mohn, in January 2024. The case marked the first time a defendant in Pennsylvania was also convicted of terrorism under the state’s statute.
After the killing, Mohn posted a disturbing 15-minute YouTube video displaying his father’s severed head and calling for violent attacks against federal officials. The video was viewed thousands of times before its removal.
Common Pleas Judge Stephen A. Corr found Mohn guilty after a week-long waiver trial. In addition to murder and terrorism, Mohn was convicted of firearms offenses, abuse of a corpse, terroristic threats, and criminal use of a communication facility.
Investigators revealed that Mohn meticulously planned the murder for years, motivated by anti-government extremism. Evidence included handwritten letters, online search history, and a “battle plan” that targeted federal employees. DNA evidence and a “to-do list” referencing the murder were also recovered.
Michael Mohn, 68, was a longtime federal employee with the U.S. Army Corps of Engineers. His family delivered emotional impact statements during sentencing, describing him as a loving husband and father who provided unconditional support to his children, including Justin.
Following the murder, Mohn fled in his father’s car and was arrested at Fort Indiantown Gap with a loaded pistol and survival gear. He expressed no remorse, instead blaming the government for his failures.
Bucks County District Attorney Jennifer Schorn praised the law enforcement agencies and prosecution team who brought the case to trial and offered condolences to the grieving Mohn family.
“The conviction of Justin Mohn closes a dark chapter, but the scars left by his monstrous actions will undoubtedly remain,” Schorn said. “His actions were not only heinous—they were a deliberate and calculated attempt to incite widespread violence and terror.”
“This case stands as a powerful reminder of the dangers of radicalization and domestic extremism, and the courage required to confront them.”
The case was prosecuted by First Assistant District Attorney Edward Louka, Deputy District Attorney Ashley C. Towhey, and Deputy District Attorney Christine Sassane. The investigation was led by detectives from the Bucks County District Attorney’s Office and Middletown Township Police, with support from the FBI, Pennsylvania State Police, and Fort Indiantown Gap Police Department.
