The Headless Gringa
There’s a legend that during WWII, Baltra Island near the Galapagos was haunted. Early in the war, an American serviceman lived on the island with his girlfriend. When he found her unfaithful, he pushed her off a cliff and she was decapitated by rocks at the bottom.
For the remainder of the war, the air force base was reportedly haunted by her spirit, who targeted solitary men and killed them. Several service men were found mysteriously deceased during their tour of duty there.
