It would depend on who you ask as there are many differing opinions about the Ripper letters. Some claim that only three of the approximately 500 posts sent were actually sent by the killer. There is really no way to tell for certain due to the fact that JTR was never found.
If you mean the likelihood, given that it is now over 120 years since his crimes and there is no surviving DNA evidence etc., it is extremely unlikely that Jack the Ripper's identity will ever be known for sure.What would be required is contemporaneous (i.e. circa 1888) physical evidence that has not been compromised by the passage of time. A written confession would be inconclusive without supporting physical evidence and would always provoke suspicion of a hoax (as with the Jack the Ripper diaries of the 1970s and 80s).There is certainly a lot of "undiscovered" Jack the Ripper memorabilia out there, and it is a well-known fact that police and others associated with the case at the time kept "souvenirs". Purported "Jack the Ripper" letters still surface from time to time and there is a roaring trade in memorabilia on the internet and through auctions etc. Whether any particular item is genuine is really anybody's guess.
Literally, hundreds of letters claiming to be written by Jack The Ripper were mailed to the local newspapers, police and with the 'Lusk' letter, civilians that played some part in the Ripper saga. Inspector Freddrick Abberline even received at least one telegram signed Jack The Ripper. Initially the great majority of the letters were discounted as fakes, and it is probably true that some were sent by pranksters and/or people with a sick sense of humor. But on closer inspection it seems that many of the letters thought to be a hoax may have more merit. In conclusion, there are very few letters remaining after two world wars and several reorganizations of storage spaces withing Scotland Yard. Not to mention, a slow but steady attrition due to pilfering by souvenir hunters and the curious. It may be helpful to take a second look at what remains of the Ripper letters using modern forensic tools available today.

hoax
I believe Nature records itself, and later repeats itself another time another place, and read the extraordinary assassination similarity between Presidents Abraham Lincoln and John F Kennedy beyond mere coincidence, but replayed in similar fashion. Jack only killed at weekends, the same with Sutcliffe: Jack killed young women, and Sutcliffe similar: A witness said Jack was seen about five foot eight tall, was bearded and soft spoken: Sutcliffe was five foot eight tall, and soft spoken: I read regarding Jack the police coverage and newspapers the greatest ever: Our newspaper, police and TV coverage perhaps the greatest ever: Regarding Jack the Inspectors received several letters from the man himself, and considered either genuine or hoax: Regarding Sutcliffe the Inspectors received a tape from either the man himself, or hoax: I read Jack suspect arriving horse drawn carriage: Sutcliffe visited driving either a lorry and car: I read major suspect Sutcliffe was interviewed several times and released, and taking these similarities further if someone checking police archive documents regarding another major suspect interviewed several times and released, it could be the man himself, and married same as Sutcliffe.
The actual diary that came to be known as Jack The Ripper's Diary has been studied and deemed a 'hoax'. The diary was from the Ripper's era, Victorian age London. That part was authentic. But the book was written by English businessman James Maybrick, not the real Jack The Ripper. The idea that Maybrick could have been the Ripper is quite amusing. At the onset of the Ripper murders, Maybrick was well into his 50s. Lived way outside London, with a considerable commute time, and most prohibitive of all was the fact that Maybrick was a long-time arsenic addict. Arsenic, a heavy metal poison, had taken a huge toll on Maybrick by the 1880s. He was weakened, had numbness in his feet and hands that was spreading, and spent most of his waking moments when not doing his business, in the pursuit of his next 'fix'. To make matters worse, Maybrick had a wife that had taken on a lover, Maybrick all to aware of this, seemed to be in a quandry as to what to do about it. This was the supposed reason for him roaming the east end hacking up down-and-out prostitutes. The whole idea is rediculous. The crimes of Jack The Ripper are sexually motivated, not revenge. They were not about a cheating wife. And Maybrick, by the time of the murders, was having problems physically due to his due to his long-time addiction. So if we look at the entire picture, Maybrick was the wrong age, wrong personality, had no motive, he was not in the city at the time of at least several of the murders. The actual diary as far as I know was never published. You can find books about the diary and about Maybrick and although the diary is from the Victorian era, since it really has nothing to do with the real Ripper case it has more or less faded from the spotlight.
There was no feud. The whole thing was a hoax perpetrated by both men. A joke.
No English word uses all those letters. Here are some 4-letter words: baud, daub, doux, habu, hoax
Jack the Ripper: The Final Solution is a book written by Stephen Knight first published in 1976. It proposed a solution to five murders in Victorian London that were blamed on an unidentified serial killer known as "Jack the Ripper". It proven to it was well made hoax. I read it when it came out. Book or not, I think that the ripper was a poor man. Anyone that has worked in a butcher shop, knows how to cut organs apart.
Yes, the word hoax is an abstract noun; a word for a deception. A hoax is an abstract concept.
here is an exampl: "Matt and I have different PERSPECTIVES."From his perpective it was simply an amusing joke, the police however treated it as a bomb hoax.
