I think it is safe to say that of the hundreds of letters sent to Scotland Yard and the newspapers there were many different authors. With multiple writers, there would be multiple reasons. Although it boggles the mind, there are many people who think that sort of thing is amusing.
Other names for Jack the Ripper were "The Whitechapel Murderer" and "Leather Apron". //He also called himself Saucy Jack. Depending on which letters he really wrote, there were other names.//
He probable was but judging by the letters he wrote he showed no remorse what so ever.
While 100s of letters claiming to be from Jack the Ripper were given to the authorities, we don't know that any of them were actually written by Jack the Ripper. Some letters are signed "Jack the Ripper," some are signed "Leather Apron" (which is what the murderer was often called before the name "Jack the Ripper" became popular), one is signed "Catch me when you can Mishter Lusk".....On and on and on.In short, no one knows which, if any, was the real signature.There is a book of these letters available if you would like to learn more. It includes transcripts and pictures.
Scotland Yard detectives. It was easy once they received several letters signed Jack The Ripper. That made him the number one suspect.
Threat is not quite the right word. Many of the letters were taunting, it's part of the game.
Everybody seems to have their own favorite suspect as Jack the Ripper. There has never been a shortage of suspects or opinions on the identity of this notorious killer. I have studied the crimes of the Ripper and read many books on this subject including modern investigations using 21st century investigative tools and my opinion is that Walter Sickert was the Ripper. There is DNA evidence that links letters of Sickert's to some of the Ripper letters. This is but one example of the many "coincidences" that ties Sickert to the Ripper crimes.
