The discovery of a human burial within El Mirón Cave, located in northern Spain, and dated around 18,700 calendar years ago intrigued us about who that person was, why they were buried there, and how they lived and died. A multidisciplinary archaeological approach, likewise a current Crime Scene Investigation (CSI), has allowed us to ascertain that she was an adult female, her type of diet and even the possible clothes she wore. Her body was completely covered by red ochre and marked by rock engravings as a possible grave offering. However, the complete human body of this woman was not found at the cave. Where the rest of her body is will be explained in this talk. Besides, the recent publication in Nature of her DNA has allowed reconstructing the expansion of humans into Europe after the Ice Age.
