The problem is, that the pic of him in his ID is from about 2001. Nobody knows, how he was looking 6 years later and even older. So unfortuneatly it is nothing more than speculation.
More interesting to me is the fact, that HCW puts the time of an end of the investigation further and further as if he waits for something to happen, that he may have expected earlier.
At a time, when a lot of alleged german darkweb paedo perps aren't tangible, because of their own investigations and trials and some of them seem to be, as if they still have to be found in the world, because they ran away some years ago.
Obviously HCW seems to wait for some external factors he isn't able to control by himself and that should be more than new clues made by possible witnesses.
