The document discusses the legend of the Chupacabras, a mysterious creature said to attack and drain the blood of livestock in Puerto Rico and other regions beginning in the 1990s. Sightings were reported across Latin America and the southern United States. Witnesses described it as resembling a kangaroo with claws that moved on all fours and left strange puncture marks on animals. Hundreds of livestock killings were reported in Puerto Rico in 1995. Theories suggest it may be a mutated animal or the result of secret government experiments, but its existence remains unproven.
