Werner Weber is a freelance journalist who wrote Another Monster. He became interested in Johan's case because he has been working in another case he has been following. The case, the Gustav Kottmann axe-murders, Weber claims, was inspired by Johan's action ten years before Kottmann committed his serial killings. He disappeared after confronting Hermann Führ.
There is not much information given on this person. But from reading his manuscript, this much can be deduced: He is Austrian and originated from Vienna. He is formerly an illustrator for an Austrian newspaper.
