Possible human mutilations by extraterrestrials?

I've wanted to write about cattle mutilation for a little while but several people have done a better job than I think I could do.  Instead I'd like to bring your attention to a lesser-known but more disturbing phenomenon.  Cattle aren't the only animals being mutilated by the military or extraterrestrials or whoever is doing these things.  Among the other animals are horses, sheep, buffalo, deer, dogs, and cats.  The most disturbing revelation perhaps is that these mutilations may be happening to human beings.

I became aware of a specific case a few years ago but it seems that still not that many people know about this phenomenon.  That's possibly for the best considering the implications this particular case could have.  The popular theory is that extraterrestrials are doing these mutilations as it is not believed that humanity has the technology.  If this is the case then we should seriously rethink how we view the UFO and abduction phenomenons.  The mundane explanation for this particular case is murder by a drug cartel.  I struggle to believe that the peculiar characteristics could be replicated by human technology.

The summary is that this body was discovered in Brazil in the Guarapiranga Reservoir.  The body bears many similarities to cattle mutilations including removal of organs through peculiar holes, evidence of high heat or laser cutting instruments, the operation appears to have been done with speed, and it appears as if the subject was alive for all of this.  The articles below tell the story better than I can.

WARNING:  The links below have their own warning notices but both contain graphic images of a mutilated human being.  If you are squeamish then I do not recommend viewing the images and probably not the second link at all, just to be safe.  The first link has all of the images at the bottom of the page so you can read the information without viewing the images if you prefer.  The second link has the images interspersed with the text.  View at your own risk.  You have been warned.

This page tells of three human mutilation cases that include the specific case I have talked about above.  There is ample warning before you see any graphic content.

This link focuses on the specific case I've mentioned and asks more questions.  However, the graphic images are interspersed with the text.  View at your own risk.
