Mohn was arrested after killing his father and showing his decapitated head in a YouTube video, a local prosecutor said. The chilling video was removed after garnering over 5,000 views, according to CNN reports. During the video, Mohn claimed to be a militia leader and condemned his father, who worked for the federal government, as a traitor, NBC News reported. The arrest followed police finding Mohn’s father decapitated in the family’s home. Mohn was denied bail and remains in custody as per the Bucks County court order.
