In June of 2010, Puerto Rican police officer Miguel Negron was on patrol with another officer when they heard what they described as the "beating of powerful wings." At the same time, they were hit by a powerful, rotten odor coming from what they believed to be a large, bat-like creature.
It wasn't an isolated report. Numerous residents in southwestern Puerto Rico were claiming attacks and sightings of the bizarre, winged thing that year. Reading over the reports, one imagines a winged gargoyle swooping down from the skies.
Perhaps the most intense report was from a man named Valdo. He told police that he was attacked in his yard one night by a "large winged animal" that swept down on him and left deep claw marks on his chest and back before he was able to escape.
Locals claimed that the creature would come out to hunt during the night, and could also be seen in the early hours of the morning. They believed that was living in the underground tunnels and ruins surrounding the Guanica Sugar Mill.
The creature was described as a huge humanoid like being with large wings resembling those of a bat. It was blamed for the slaughter of numerous animals in the region as well as attacks on several local residents. Purportedly, the creature was a blood drinker much like the infamous Chupacabras.
