Why was Lewis Carroll suspected as Jack the Ripper?

His name was Charles Lutwidge Dodgson. He was an English writer, mathematician, logician, Anglican deacon and photographer. In the same year that he became a photographer he published his first piece of work under the name that would make him famous which was a very predictable little romantic poem called 'Solitude' that appeared under the authorship of 'Lewis Carroll'. He died 10 years after the ripper's killings and the theory goes when some one arranged sentences of his works and it would produce sayings that the ripper used in his letters.
