A skeleton from the family closet

This is a picture of my father (the one with the hat) taken in the summer of 1940 in the town of Boyabat in northern Turkey. If I am remembering it correctly, he was the hükümet doktoru (government doctor) of the town with duties including those of a coroner. Based on what little visible of the surroundings and the condition of the corpse, I guess the picture was taken outside of the town.

As for additional details of the case, I have none.
