Overview

• The trial began Monday in a Bucks County courtroom, where Mohn is charged with first-degree murder, abuse of a corpse and multiple terrorism counts for the January 2024 slaying of his father.
• Prosecutors allege he shot 68-year-old Michael F. Mohn with a newly purchased pistol, decapitated him with a knife and machete and posted the 14-minute YouTube video online.
• Later that day, Mohn was arrested at Fort Indiantown Gap while armed with a handgun and found with a USB drive containing photos of federal buildings and bomb-making instructions.
• Investigators say his online writings and the decapitation video included violent anti-government rhetoric aimed at inciting Pennsylvania National Guard troops to rebel against federal authority.
• Defense attorney Steven M. Jones said he does not expect a plea deal, setting the stage for jurors to consider the full case.
