Overview

• On July 11, Judge Stephen A. Corr found Justin Mohn guilty of first-degree murder, abuse of a corpse and terrorism-related offenses before imposing life without parole
• Mohn testified that the killing was his “Plan B” after a failed attempt to perform a citizen’s arrest on his father for alleged treason
• Prosecutors showed the 14-minute YouTube video of the beheading, which remained online for hours and featured calls to overthrow the federal government
• Authorities arrested Mohn later the same day at the Pennsylvania National Guard’s Fort Indiantown Gap and seized a USB drive with photos of federal buildings and bomb-making instructions
• The case has highlighted gaps in social media moderation and raised concerns about the threat of homegrown extremist violence
