An individual on 4Chan discovered something very disturbing about their grandfather after he passed away — a secret bunker with what appeared to be human bones and weird faces carved into the walls. The post was deleted soon after it was made back in 2012 but screenshots of the post and the pictures that accompanied it have been floating around online along with the story that accompanies it. Due to the disturbing nature of the post, it’s naturally become a popular topic to cover for true crime YouTubers and creators whose content revolves around unsolved internet mysteries. One such YouTuber, by the name of Coop, documented the old case with screenshots of the post to accompany it. 4Chan user describes his grandfather’s creepy bunker The original poster (OP) starts his post by claiming that his last living grandparent, his grandfather, had passed away at the age of 89. The man had apparently been a WWII veteran and the OP claims that he was paranoid that another war could break out at any moment. As such, he had created a bunker to prepare for the oncoming apocalypse, or at least that’s what OP thought the bunker was for. Anyways the 4Chan user claims they asked their grandfather about the bunker once but that he had told them to keep away from it telling the OP that it was “just a ____.” They explain that they could not understand what the last word was that the grandfather had used to label the bunker although they claimed it sounded like he said “ah Sioux air.” Who knows what kind of horrors were waiting in that bunker. Investigating the bunker After the grandfather’s death, OP took the opportunity to explore the old bunker. They had been expecting to find rations, and other tools to help survive a nuclear war, but what they actually found was way more disturbing. Travelling down the winding tunnels that had been carved into the rock, OP came across a large iron door bolted shut with a padlock. Luckily it was rusty enough to break easily and OP was able to eventually pry the door open. In a room further back they found a cross carved into the stone along with a bunch of faces which had also seemingly been carved by the grandfather. Pictures of the faces had been shared along with the post and the strange carvings are certainly unnerving. But it gets worse, as OP looked at the ground, they noticed what they insist to be a human bone underneath some rubble. They then noticed even more bones coming out of the concrete. OP claims they heard a laugh from somewhere in the tunnels prompting them to bolt from the bunker as fast as possible. What was that place? Since then there have been no updates on the situation although some have suggested that the bunker was being used by the grandfather to bury loved ones. Another 4Chan user suggested that the word he had used to describe it (the one OP couldn’t understand), might have been “ossuary,” which is a place where the bones of the dead are stored. Whatever the case, it’s yet another internet mystery we may never get the answer to. Who even knows how much of the story was fact and what was made up. Although what the OP would get out of making up such an elaborate lie only to delete the post shortly after posting? We may never know for sure.
