I was living in Naples, Florida when the news was first reported that a man had been found deceased inside a tent in the woods of the nearby Big Cypress reserve area. And I remember that the angle of the story was one of mystery as to just how the man had died and that his identity remained undetermined. The case was in the news for a few days, then it essentially vanished and we, the public, moved onto other things.
So I was genuinely a bit surprised to learn that the search to find out just who the person was and how he died had become such a massive undertaking by those people on the Internet who style themselves as amateur sleuths.
This documentary is an interesting look at how those Internet communities, along with law enforcement and the assistance of a sophisticated DNA lab, were finally able to determine who the deceased man, known by his trail hiking name as "Mostly Harmless," actually was, and just what his backstory consisted of.
And the final reveal definitely included some real surprises, once the actual truth is discovered.
Like all of these kind of modern documentaries that look at the world of amateur sleuths who immerse themselves in true crime and other similar unsolved mysteries, there is good and bad and even some extremely ugly aspects to what people will allow themselves to devolve into so far as their emotional investment in a case is concerned.
Worth a watch if you enjoy this particular genre.
