Man charged with killing father after showing off his 'decapitated head' in YouTube video

Justin Mohn, 32, from Pennsylvania, has been charged with first-degree murder and abusing a corpse after police found his father decapitated in the bathroom of his home in Bucks County on Tuesday night.

In the YouTube clip, Mohn is seen wearing gloves and holding his father's head in a plastic bag. Later in the video, the head can be seen in a cooking pot. The video has since been taken down.

Mohn then denounced his father as a traitor for being a longstanding US government employee, and called for the death of all federal officials, NBC News reported.

It added that Mohn espoused right-wing conspiracy theories and spouted them in the 14-minute-long video which was removed because of "strict policies prohibiting graphic violence and violent extremism", according to a YouTube statement.
