In the mid '90s reports of a strange creature killing livestock and sucking their blood travelled across Puerto Rico. Animals would be found dead in the morning, with three puncture wounds in their chest, and no blood in their bodies. Then came the sightings of beast unlike no other. Reports of how it look vary, but the death it leaves behind does not.
