When finding a source for Mr. Kath today, I initially spoke with someone from Property Preservation who told me some details surrounding the property that was demolished. He didn't reveal anything surprising, but still, I'm not sure how much I can say in a public forum. So, I will say this: I do not believe the owner's claim that the City has not contacted him. I believe that they have been trying to get a hold of this man, but he has not responded. I'm not completely sure, but I got the impression that they've been trying to contact him for longer than just the past day.
Mods: Please feel free to delete my above comment if it conflicts with WS rules. I know the above info isn't from MSM, and instead from a personal conversation, so I understand if this isn't acceptable.
In addition, the person told me that the interior of the house was a mess and very unsafe. Pretty much consistent with descriptions other sleuthers have already posted.
My opinion: I think the City has been trying to tear this house down for a long time, but ran into a lot of snags with the owner. With all the media attention on the house, they probably realized that there would be residents/media/people who would complain about why the City isn't taking care of dangerous houses, so the City hurried to demolish the house. I'm hoping they preserved any potential evidence. They do a good job (maybe I'm biased), but I'm confident they did everything correctly.
I also think that this house probably has nothing to do with Lisa's disappearance.
All right, I'm signing off WS for the night. I'm praying for good news over night or tomorrow.
