> A Ukrainian national, whose last known address was in Poland, is being sought by German authorities ... [three German news outlets reported on Wednesday] that the suspect is a Ukrainian diving instructor, named only as Volodymyr Z. for privacy reasons.
Sounds like token-at-best privacy to me.
Also a somehow familiar name. Not that I know of many Ukrainians, but I definitely know of one named "Volodymyr Z".
OK, TBF, could be that precisely because of this, they thought that it would be obvious that it's a pseudonym. If it is.
