Back to the blood dripping on the exterior wall (sorry!).
I'm currently building my new house right now. I live relatively close to Moscow, but in Washington, so our building codes and the way we build for our climate should be similar. I go back and forth if that is actually blood or not. I will say this, heating oil is
rarely used in the PNW and it looks like it can be confirmed this home had electric heating.
I wanted to share a photo of my home so people can maybe visualize the construction a bit better.
On top of the concrete foundation there is a foam material (acts like a gasket) placed between the sill plate and the foundation. The sill plate is 2" x 6" pressure treated lumber which the vertical lumber is then attached (framing). When the home is insulated, a heavy-duty caulking is applied around the entire base of the home to seal it even further. You'll see my insulation is currently being installed, when they are done installing the batts, a Visqueen vapor barrier will be installed on top of that (further sealing it), then the sheetrock, flooring, baseboards, etc.
I will say that darn, it does really look like blood dripping, but I just can't see it seeping out like that (unless this is a very shoddy built home). I also go back to all the reports that say the victims were killed in their sleep, which to me means they were in their beds. Sorry for being graphic, but wouldn't the mattress act like a sponge and absorb the blood?
Anyway, I have no idea if it's blood or not but thought it might help to show the construction process a bit.
