Jack The Ripper In America. Did Jack The Ripper Visit The United States?

In October of 1893 a New York newspaper received a letter supposedly from Jack the Ripper and in it were details of the murder of Carrie Brown the prostitute who was murdered on April 24th 1891 in New York City. It is said the letter contained details that only the person who committed the crimes would have known. In the letter it stated that Inspector Byrnes wasn't able to catch anyone much less Jack The Ripper. If this letter was truly from Jack The Ripper it is the last known correspondence from him. That letter is still in the possession of the New York Police. A Police Inspector from London's Scotland Yard came to New York City and examined that letter and said to him the letter appeared to be in the same hand writing as the letters received by London's Scotland Yard Police.
So what do you think about the New York Murders. Do you believe it was the work of Jack The Ripper. Do you believe that Jack the Ripper came to New York where he committed at least four brutal murders in the spring of 1891. And what happened to Jack the Ripper if he did commit those four murders in 1891. Why did he stop. Where did he go. Its quite possible he simply moved on to another city where he continued to kill. But if so he took no credit for his crimes.
