Method of Operation
It is commonly believed that the Ripper hired these prostitutes at first . Upon getting the opportunity , he would seize the women by their throats and would strangle them until they were unconscious if not dead . The autopsies constantly revealed clear indications that the victims had been strangled . The Ripper then lowered his victims to the ground . Lastly , he cuts the victim ’ s throat . Splatter stains show that the blood pooled beside or under the neck and head of the victim rather than the front which is where the blood would flow if they had been standing up .
He did not violate the bodies sexually and usually he took a piece of the victim ' s viscera . The taking of a " trophy " is a common practice by modern sexual serial killers . In the opinion of most of the surgeons who examined the bodies , most believed that the killer had to have some degree of anatomical knowledge to do what he did . In one case he removed a kidney from the front rather than from the side , and did not damage any of the surrounding organs while doing so . In another case he removed the sexual organs with one clean stroke of the knife .
The Ripper Letters
It is commonly accepted by the experts on the case that none of the letters purported to have been written by the Ripper were in fact written by him . The Whitechapel Murderer may have written the letters , but there is no evidence to suppose that he did and the police seem convinced that they were the work of a journalist . One other letter may have been written by the killer . It was found inside half a human kidney , which was delivered to the police .
Suspects
A number of people were suspected to have been The Ripper . In 1894 , Sir Melville Macnaghten , Chief Constable , wrote a confidential report in which he names the three top suspects . Macnaghten ' s first suspect was M . J . Druitt , a barrister turned teacher who committed suicide in December 1888 . The name of the second suspect was confirmed as Aaron Kosminiski , whereas , the third suspect , Michael Ostrog , has been investigated and there is nothing to indicate that he was nothing more than a demented con man . Similarly , every suspect in one way or the other created a controversy .
