james kelly = jack the ripper?

“Jack the Ripper" is the best-known name given to an unidentified serial killer who was active in the largely impoverished areas in and around the White chapel district of London in 1888.  Since that time, the identity of the killer or killers has been hotly debated, and over one hundred Jack the Ripper suspects have been proposed. 

 James Kelly is one of the suspects.  I don’t think that James Kelly is jack the ripper. It is because there is no concrete evidence.  He did kill his wife, but why he has to take a very long time to kill again.  Beside he is in United State when other prostitutes are killed by the real jack the ripper. Other than that is the handwriting of jack the ripper and James Kelly are different.  James Kelly is just a psycho person but he is not jack the ripper.
