While surveying a cave known as Errotalde I, near the town of Erro in the province of Navarra in northern Spain, a group of spelunkers discovered something most unexpected. After following multiple twists and turns down darkened cramped corridors and passageways, they stumbled across a fully intact human skeleton . The Navarra cave body had been placed carefully and deliberately on its back next to a narrow underground stream, with its arms folded tightly across its abdomen.
The skeleton was found 200 meters from the mouth of the cave, meaning those who had placed it there had exerted a great amount of effort in carrying the body to this spot. Ominously, there was a round hole in the middle of the skeleton’s skull, suggesting that this individual had been violently and abruptly killed by a high-speed projectile or rounded sharp object thrust into his head.
