In 1979, the Pereira family began to encounter strange human-like faces that appeared and disappeared in their home without explanation. Both the locations and times that the faces appear have been irregular. According to the story, one day in August, Maria Gomez told her husband a face had appeared on the concrete floor in the kitchen. Her husband immediately destroyed the image with a pickaxe—only to have it appear again later. The mayor forbade them from destroying the new face and had it cut out for testing. The faces persisted for the next 30 years, appearing as both males and females with an array of expressions on their faces. As with many other paranormal occurrences, it was found that the house was built on a graveyard and bodies were found under the house. Despite having the floor replaced multiple times and cleaning the faces with detergent, they continued to appear without explanation. Skeptics claim the faces are a hoax, created with the use of an oxidizing agent.
