The photographers and storymakers are likely from S*o Paulo -
   their level of technical prowess is ASTOUNDING - we used them
   back in the late 90s/early 00s when I worked for BIG PHARMA
   (yes, yes I did - Schering-Plough when it existed)- and I made a
   lot of Portuguese friends on Orkut and learned a few brazilian
   things to say as well. These videos (and they know it) play on
   American ignorance of the state of technology around the world.
   They also make _really_ gruesome horror movies. Film students
   from Brazil. They know we're suckers. tongue emoticon
   Hypothesis: Local Newspaper in Itajuba would report the
   incident.
   Method of data collection: Find local newspaper. Do a search.

   Searched for anaconda.
   No mention of the incident. We're on the same Internet.
   It's like the largest public library in the world.
   A single source of evidence is never enough, including my
   search, but my rule of thumb holds: If it's SHOCKING, there's a
   good chance that its made up to get clicks. Called CLICKBAIT
