The Dark Connection Between UFOs and Grisly Mutilations. The details are both grisly and strangely surgical: corpses found under the open sky with their eyes plucked out, tongues removed and private parts excised—all extracted with the utmost precision and leaving not a drop of blood. Reports of such unexplained mutilations, carried out on both humans and animals, have baffled investigators for decades, leading to speculation about whether the perpetrators might be otherworldly beings conducting biological experiments on earth’s inhabitants. While scores of reports have emerged from U.S. western and midwestern states detailing mysterious bloodless animal mutilations, human cases have been far less common—and often much sketchier in their documentation.
