#8. The Suspects
There were various suspects for the Whitechapel murders. Of these, the most serious ones included Michael Ostrog, a Russian doctor; Aaron Kosminski, a Polish immigrant; and Montage John Druitt, a barrister. All three were considered maniacs and disliked prostitutes.
#9. The end of killings
In the autumn of 1888, the murders ended abruptly after the fifth victim, Mary Kelly, the worst mutilated victim of all. Nobody knew what happened to the murderer, whether he died, gave up or was imprisoned.
#10. The unusual suspect
There is another theory that suggests that Jack wasn’t actually ‘Jack’. The idea was raised by the lead inspector Frederick Aberline who suggested that the murderer might have been a woman. After all, there would be no better way to throw everyone off if nobody was looking for a woman.
