If you are coming to this post unaware of who Justin is, was, then you have two choices: either read THIS past blog post first and then come back here or skip this post and await my next Germanic travel related post in the days to come.
So I have now heard back from Erik, the close friend of Justin and so I have posted his response below. Apart from it again being excellently written, see what you think as it leaves me with more questions than answers although he does kindly answer a few of my own.
Strangely I've learnt just as much, if not more, from the private independent research my German friend Lukas undertook and so I will supply you the link too as this reveals where Justin was when he chose to end it. It really made me shudder when I saw the official news article, a couple of images that you see on television.
Please note that if you think the name in the link looks familiar, it won't. It is not the place some well travelled European folk might think it is and I first thought as we know he returned home to the US mid June I believe.
