Justin Mohn, who is believed to be the victim's 32-year-old son, was found two hours away, near Fort Indiantown Gap in Lebanon County. A YouTube video was posted by Mohn that's believed to be connected to the sick crime, a detective from the police department told The U.S. Sun. 'THE MESSIAH'In the video, Mohn fired off wild allegations against the federal government while appearing to hold up his father's head. "We have told (the victim’s wife) to notify them before they see the video, or the video is sent to them."
