Justin Mohn is a YouTuber who was famous for making a video of him with his father's decapitated head using a machete. His father was a federal worker, so he killed him. The video shows him rambling about his father being a federal worker and he held his dad's head, the dad's head being wrapped in saran wrap. The end of the video showed his father's head in a vase. According to some comments, he was completely aware of what he did and had a concise plan before doing it. The video was on YouTube for 6 hours before it was taken down. Justin's mom found his organs exposed infront of the sink.
I've heard of Justin Mohn killing his father. This is the reason you shouldn't have kids.
