0 hour(s) and 23 minutes - Movie - 2016 On the topic of History's Greatest Unsolved Mystery, the six items up for consideration between Craig and the panelists - author/comedian Michael Ian Black, comedian Josh Wolf and actor Jason Biggs - are: robber D.B. Cooper parachuting out of a hijacked plane over Nevada in 1971 with his ransomed $200,000 never to be seen again; Jack the Ripper, known to have killed six women in the late nineteenth century London, never having been identified; the Zodiac Killer terrorizing San Francisco in the late 1960s, he never having been caught or identified despite his own contact with the press; the reason for and the people behind the statues on Easter Island being unknown; the reason for and the people behind Stonehenge being unknown; and the unsolved "Black Dahlia" murder of Elizabeth Short in 1947 Los Angeles. Beyond the merits of each of the six, the panelists divide five of the items into two categories, the serial murders and the structures. With the serial murders, they take into account the number of people killed in each instance. They also discuss which of any of the killings could have happened today without more evidence having been collected let alone positively identifying the murderer. With all six, they look at how much of the story is known as opposed to unknown. They conclude by talking about mysteries that did not make the list but perhaps should have.
