Hello everyone, thank you for taking the time my question is this:
With the various sources getting so many letters from different places and so on how did they determine what came from the real Ripper? Now a days we have letter writing analysis and fingerprint analysis and so on but how did they at that time determine the letters to be from the same guy other than just possible similarities in language and so on
