Hundreds of letters were sent to authorities from people claiming to know Jack the Ripper or claiming to be Jack the Ripper. They were all probably fake, but one was sent along with a human kidney and could have actually been from the murderer. Or it could have come from a medical student with a stupid sense of humor.

Previous Answer: there were 2 fake letters what impersonantors wrote and 1 real one from the real jack the ripper.
Of the hundreds of letters that were sent to Scotland Yard in the wake of the Ripper crimes, only a handful were deemed authentic. But many of those letters were materials that an artist would have. Resin, art pencils, ect. In the 2002 book, Jack The Ripper Case Closed, author Patricia Cornwell had those 'bogus' letters, cards, and drawings analyzed and they were consistant with the Impressionist Victorian painter named Walter R. Sickert. Anyone who knew Sickert would know how much he loved to write letters to friends, buisinesses, and most of the newspapers. He could write dozens of letters just to newspapers in one day.
He didn't. Jack the Ripper was never caught.
He killed and ripped woman's bodies. The police received a boasting letter from a man claiming to be the killer. It was signed Jack The Ripper.
The London police never held the opinion that Jack the Ripper was murdered... he just stopped killing for reasons known only to him.
The killer refered to himself by several different names, Jack The Ripper and Saucy Jack are just a couple. He obviously had a flare for the dramatic. Jack The Ripper has become almost legend thanks in part to that 'oh so appropriated' name.
Frederick George Abberline - Chief Inspector for the London Metropolitan Police.
Thomas Cutbush was named as the Ripper by the Sun newspaper on the 13th February 1894. The possibility of Thomas Cutbush being Jack the Ripper was thoroughly investigated by the police at the time, and shown to be without foundation.
Jack the ripper was the first serial killer to reach the media. The world has eyes on him. It was a scandal about the condition the police was at that time. There were no false starts in this case. There was nothing to go on but the remains of the victims. Even today it takes quite some time to catch a murderer on the run, but in the case of Jack the Ripper, there were many aspects police today would not come across.
police was not as affective as they are now and there was no way of finding pepoles DNA
Nobody knows who Jack the Ripper was.
Jack the Ripper was never caught because forensics and police detection was not advanced enough to apprehend a criminal such as the Ripper. He was also very lucky.
Scotland Yard never claimed to have captured Jack The Ripper and in fact were ridculed for their inablity to catch him. It resulted in many conspiracy theories, some involving the royal family, the police force and even Inspector Fredrick Abberline.
