In 1995, a beast dubbed “El Chupacabra,” spanish for “The Goatsucker,” was first sighted and accused of killing and draining the blood of hundreds of farm animals in Puerto Rico. Eyewitnesses describe it as a two-legged reptile-like beast with sharp claws and sharper fangs. But another rash of sightings, and killings, in Texas last year produced eyewitness descriptions of a creature that looked very different. This episode will go on the hunt for the Texas chupacabra. And for first time on television, DNA tests will be performed on evidence from both the Puerto Rico and Texas sightings in effort to scientifically prove just what these mystery beasts could be.
