An Older Couple in a Home covered with Strange Illuminati Markings in E. Carnegie. The home is gone . .Where are they now ?

I would have never known this home ever existed at Alter St and Bert Way had I not been called to do some work at a nearby personnel care home.in E. Carnegie a part of the city of Pittsburgh that borders Scott Twp. and Carnegie.Boro 

In the end of  alleyway behind the care home was a simple white clapboarded house with a yard filled with debris and an older white couple who where sorting it. . But what seemed to be a hoarding situation had a strange twist the home was covered with all kind of strange Illuminati and  Free Mason type symbols the all seeing eye, the masons compass , the pagan pentacle  etc .
The home did not appear to have utility's possibly just electric as they used wood to heat and they where hauling in jugs of water. 
Rather strange I thought till one day the couple saw the Personnel Care home had a pile of  walkers and other scrap metal outside and the couple asked if they could take it the owner agreed and I got to talk to them for a few minutes never learned their names but they said they where on disability and scrapping by where they could  by picking up scrap metal and such for recycling they had an old ford pickup failing apart they held together with tape and bailing wire literately.

Thats when I asked them about the symbols on their house and they started telling me all about how government was suppressing us all how they where being assaulted by radio beams ,fluoride in the water etc. Yes you name it they where full conspiracy believers even gave me some CD Disks I still have on all kind of conspiracy's.  ,but they where harmless and never ever bothered anyone but had made their home a Bill Board of their beliefs.

Apparently the City had enough and I came by to do work at the Personnel care home and the yard was cleaned up and home freshly painted and up for rent  and 6 months later it had been torn down now just an empty lot which I thought strange why bother cleaning it up if your going to tear t down but it must have been too bad a shape for any home flipper to want it. All there is now is an empty lot and some trees you would never know such a home and the couple who lived there ever existed.
