Answer 5

One of the most puzzling mysteries in history was the identity of Jack the Ripper.  He was a psychopathic killer who roamed the streets of the White Chapel section of London, preying on prostitutes, in the 1880's and 1890's.  He sent teasing letters to Scotland Yard, even enclosing the kidney of one victim.  He got his name by the way he dismembered, or "ripped", his victims, and by signing his letters "Jack."  There have been several theories put forth as to what his identity might have been, including:

1.  The Polish doctor--he showed a great deal of knowledge about human anatomy in the way he disembowled his victims.

2.  "Leather Apron"--possibly a meatcutter

3.  "Prince Eddie"--a member of the royal family was whispered to have taken part.

4.  An insane midwife, because one of the victims was pregnant at the time.

5.  Dr. Harvey Crippen, who was charged later with poisoning his wife, though mass murderers rarely tend to change their method of murder.

In the mid-1890's, a member of Scotland Yard assured the public that there would be no more Ripper killings, which has been taken to mean that Jack the Ripper had either been killed or taken to an insane asylum.  However, not long after the killings stopped in England, another spate of murders much like the Ripper slayings, took place in the U.S., also leading to speculation that the Ripper only left England to continue his murders elsewhere.
