I don’t know the details or have any more information, but there is a background as to reporting suicides in Germany.
Usually, it is consensus between the German news outlets not to report suicides, unless it has been committed by a person of interest, usually a celebrity. This is not a law or otherwise enforced, but a common understanding of the outlets amongst each other, so there will be no promotion of suicide. Here is a source (in German, unfortunately, explaining the reasoning: deutschlandfunk.de/sagen-meinen-warum-medien-nich…)
To me, this seems to be a plausible reason for the vague language, but again, I don’t know.
