A man from Pennsylvania in the US who beheaded his father and posted a chilling video of the severed head on YouTube has been found guilty of murder and sentenced to life imprisonment without parole.
Justin D. Mohn, 33, was found guilty of first-degree murder and several other charges related to the killing of his father, 68 year old Michael F. Mohn, at their home in Levittown, a suburb of Philadelphia, in the U.S., in January 2024.
The verdict and sentence were delivered by Bucks County Judge Stephen A. Corr, who presided over the bench trial, describing the crime as "unimaginable."
Prosecutors stated that Mohn fatally shot his father with a newly bought pistol before beheading him using a kitchen knife and a machete, reports the Mirror. Mohn posted a lengty video to YouTube
He then filmed a 14-minute video showing his father's severed head, which he uploaded to YouTube. The video remained live for several hours before it was taken down.
The footage included lengthy tirades about the U.S. government, immigration, fiscal policy, urban crime, and the war in Ukraine. In the video, Mohn labelled his father - a long-serving federal employee who worked as an engineer with the U.S. Army Corps of Engineers' Philadelphia District - as a traitor.
He claimed his actions were meant to intimidate federal workers and compel them to meet his demands, which included their resignation.
Prosecutors characterised the killing as "cold, calculated, [and] organised," comparing it to "something straight out of a horror film."
Bucks County District Attorney Jennifer Schorn said after the sentencing: "It's unimaginable what the defendant did to his father and to his family. I know this verdict does provide some level of justice, but it will never heal their wounds. We are satisfied that this was the right outcome to guarantee that the community at large is safe from Justin Mohn."
Relatives delivered heartbreaking victim impact statements in court, paying tribute to Michael Mohn as a devoted husband and father, a modest man with a keen wit who loved reading, keeping fit, and strumming his guitar.

He confessed to decapitating his father to deliver a warning to civil servants.
When officers arrested him later that same day, Mohn had climbed over fencing at Fort Indiantown Gap, the Pennsylvania National Guard's base.
Officials said he was carrying a USB stick loaded with photographs of federal buildings and what appeared to be bomb-making instructions.
The prosecution also disclosed Mohn had a track record of sharing violent anti-establishment rants online and had penned a correspondence to Russia's envoy to the United States, saying sorry to President Vladimir Putin for pretending to be the Russian czar and pleading for sanctuary. Mohn's defence barrister, Steven M.
Jones, described the case as "undoubtedly difficult," pointing out that prosecutors had originally pursued the death penalty. He refused to comment on whether his client would lodge an appeal.
Alongside first-degree murder, Mohn was found guilty of possession of an instrument of crime, firearms offences, criminal use of a communication facility, terroristic threats, defiant trespassing, and abuse of a corpse.
Throughout the trial, the judge warned those present about the disturbing images being presented as evidence, offering them the chance to exit the courtroom before viewing them.
Michael Mohn's wife, Denice, gave evidence that she and her husband had been providing their son with financial and emotional support whilst he searched for employment. She revealed that police had previously called at their home to caution him about his online posts.
Schorn branded Mohn's behaviour as showing a "complete and utter lack of remorse," describing it as an "unimaginable, unfathomable crime."
Mohn will now serve the remainder of his life behind bars without the possibility of parole.
