Context:

In Pennsylvania, Justin D. Mohn, 33, is set to stand trial for the murder of his father, Michael F. Mohn, following a gruesome act where he allegedly beheaded his father and posted a video of the crime online. The incident occurred in their Levittown home, with Justin's mother discovering the body. Prosecutors allege that Justin shot his father with a newly acquired pistol before decapitating him and using the video to incite others to join him in overthrowing the U.S. government. Arrested later that day while attempting to recruit the Pennsylvania National Guard for his cause, Justin was found with a USB containing federal building photos and bomb-making instructions. His defense does not anticipate a plea deal, and a previous competency hearing revealed Justin's attempt to seek asylum in Russia, along with his violent anti-government rhetoric online and in the video ranting about various political issues.
