However, the fact that the killer left a music box with the lullaby "Hush Little Baby" at the crime scene does not lead to a clear solving. 25 years later, the investigative journalist Stefanie Schneider, known as "Mütze", made a surprising discovery in Cologne.

The more the journalists compile, the clearer the contradictions and gaps that the investigators should have noticed at the time.
