I happen to know the woman that bought the spiral staircase from the List Mansion and now has it in her house. Her husband and her bought the staircase when they were tearing down the mansion.
I was there yesterday as she is moving to Denver and is selling everything that she can not take with her and took a pic of the staircase as it is now.
When the homeowner told me that it is was the actual staircase where the murder occurred I just had to take a pic. When we were high school in the early 90's we always passed by the "Murder Mansion" because it was so spooky looking.
Just thought I would share this random info. Hope you enjoy the info.
