What Happened?
Justin Mohn is accused of murder, attempted murder, and abuse of a corpse after fatally shooting and then beheading his father in their Levittown, Pennsylvania, home. The incident occurred on January 31, 2024, and was followed by a shocking 14-minute live video posted to YouTube. In the video, Mohn explained his motives and displayed the aftermath of the crime. The video was later removed but not before gaining widespread attention.
During his testimony on Wednesday, Mohn described the killing as “Plan B” after what he claimed was a failed attempt to perform a citizen’s arrest on his father. He testified that he believed his father, a skilled martial artist, was attempting to kill him and reached for a gun, prompting Mohn to act in what he claimed was self-defense.
Mohn accused his father of “treason” and obstructing his political aspirations. He claimed the beheading was meant as a message to federal workers, demanding their resignation and calling for the cancellation of public debt, among other radical demands.
Who Is Justin Mohn?

Justin had a documented history of violent, anti-government rhetoric and social media posts. He frequently expressed disdain for the U.S. government and its employees. Before the murder, Mohn had published extremist content online and was found with a USB drive containing detailed instructions for photographing and creating explosives targeting federal buildings.
Following the murder, Mohn attempted to scale a fence at the National Guard headquarters at Fort Indiantown Gap, where he urged others to join his anti-government movement. He was arrested shortly after and admitted to killing his father.
