The forests of Puerto Rico are said to be home to the infamous and enigmatic goat-sucking Chupacabra. Is it an alien ? A top secret government experiment gone awry ? Whatever the true nature of the creature might be, one thing is certain: it's by no means a recent phenomena as many believe. Evidence and accounts of this blood-sucking monster date back to the 1960s when a guard at the Arecibo Radio Telescope reported seeing a black cloaked figure that he later identified as the creature after a cow was found nearby mysteriously drained of blood.
