Hi there!
I've got a cover from US to Sweden, with CDS 1893. Inside this cover there are 3 letters. Two of them is written in Sweden and addressed to people that were related to my grandparents. However there is a third letter, written in English, about a trainwreck in 1895 August 5th. I've tried googling a bit after a such trainwreck on that given day but haven't found anything so far. Here are pictures of the letter, I hope it's big enough to read.

Some sort of heading.

Upper half.

Lower half.
I can read most of the letter, but the writing isn't easy and the used language is a bit historic so I haven't figured everything out.. Was hoping you could help me with it. As I have understood, it says that "we find from the evidence that the accident might have been prevented(?) by the services of a brick?/deck?-walker which was shown the Company doe not employ." ?
At the bottom it says that the undersigned certify... and correct copy of the coroners ????..., ohio office. Then at the end there is something about 14 ? 1891 or 1897?
I am a bit puzzled why this.. deathnote was inside that cover, since the swedish letters doesn't relate to this letter at all.. So probably it was inserted here later on.. Also, I haven't yet found any cover from 1895 in the collection that I've got. There is a gap between 1894 and 1898..
Auditor of Mason County Wash. Terr. is the marking on the letter and the signature at the end.
Any help would be much appreciated in this puzzle!
Thanks!
