In November 2006 in a northern Mexican town of Cuatrociénegas, farmers started to see some of their animal livestock dead and dismembered in the mornings when they checked on them. Most of the blood was missing from the dead animals and it didn't appear to be from coyotes which the farmers are used to dealing with. They feared it was from the Chupacabra which first originated in Puerto Rico.
All that is known about the creature is that is some type of canine creature that is known for sucking the blood from its prey. Two farmers determined to kill the predator started hunting it at night. This video taken on one of the nights of hunting was thought to be lost, but was recently uncovered.
