The Disappearance of Jimmy Hoffa
It's not entirely unlikely that someone like Jimmy Hoffa—an infamous labor leader and Teamster president who went to prison for a litany of unsavory reasons—would be murdered. Despite this, Hoffa's body was never found. The only evidence of Hoffa's murder was a strand of hair that matched his DNA in the backseat of a car. Even his own daughter said, "It would be a comfort to find his body, but I don't think we will."
Max Headroom TV Hack
In 1987, two Chicago television stations were "hacked" for the first time. A mysterious individual interrupted the broadcast signals and appeared on screen wearing sunglasses over a Max Headroom mask. The first hack only lasted 25 seconds, during which the person said and did nothing. However, during the second hack, he mooned the audience and was spanked by a fly swatter.
