Hello @ all,
my name is Peter. I live in Germany and am married to a woman from Yekaterinburg. I was very interested in this case a few years ago. I lost sight of it though. I have visited some places in Russia. From the Arctic Circle at minus 36 degrees to the south, the North Caucasus. And Ekaterinburg, of course. My wife's mother city.
There are a few theories on this case that I completely rule out. I consider some theories to be possible and one theory I am personally most convinced of.
But first let me delve deeper into the case.
