A few weeks ago I had the opportunity to visit Zak Bagans' The Haunted Museum in Las Vegas, where among the haunted treasures is kept the final remains of the notorious Demon House, where one of the most controversial and widely-publicized paranormal cases of the last few decades took place in Gary, Indiana from 2011 to 2014. In the museum you can see the actual basement stairs of the Demon House, as featured in the documentary, under which is the original soil from where certain items were buried under the stairs and uncovered, and these items are also preserved in the museum. When you approach the room containing these items, the door is shut with a crucifix above the door to "contain the evil within." We are warned by the tour guide to enter at our own risk, if we choose, knowing that those who had lingered in the house in the past, including Zak himself, had suffered physically and/or mentally. Everyone in my group entered the room, and one young man even had to leave because he started to get a painful headache. The reason this museum has the last remains of the Demon House, is because Zak himself had purchased it to investigate it, but when things went wrong and took a turn for the worse, he decided to tear it down in January 2016 hoping that it would never bring harm to anyone again - though he couldn't resist saving some items for his museum.
