The skull wasn’t in a very good condition because of the obvious reason. Firstly, it was unknown to the family and they only found it when they were cleaning the back room of the pub. Secondly, the skull was really old and due to its poor caring, it got yellowed with age. The skull was also missing its jaw bone and several teeth. But still, there was that one thing which was still intact in the skull. What did Dr. Wagner find during his investigation?
