HOW DID JACK THE RIPPER OPERATE?

     The speed and accuracy of the Ripper's work indicates that he knew exactly what he was doing.  Once he'd engaged a prostitute and got her to a secluded area, he strangled her until she was unconcious or dead.  Then, he lowered her to the ground, turning her head to the left. The victms showed no signs of bruising at the back of the head, so it would seem that he did lower them to the ground rather than just throwing them down.  Once the victim was lying on the ground, from her right side he would cut her throat, moving left to right.  If the victim had been standing, her blood would probably have pooled to the front.  However, it pooled beside and under the neck, indicating that the victim was indeed lying down. 
     Once the victim was dead, he would continue the rest of his work.  He would push her legs up and begin cutting open the abdomen and throwing the intestines and other entrails over one of her shoulders to get them out of his way.  He would remove one organ--in one case, a kidney or more generally a piece of the viscera.  He would mutilate the face, in addition to the dissection.  There were never any signs of intercourse or masturbation reported at any of the murder sites.
     The fact that he worked so quickly in the darkness, while keeping an eye out for passersby indicated to investigators that he may have had some sort of anatomical knowledge or, at the very least, experience in using a knife; he was able to remove organs perfectly without damaging surrounding organs.  For this reason, it has long been suggested that JtR may have been a doctor or a surgeon, though this may not have neccesarily have been the case.
     Whatever the case, JtR certainly did know what he was doing--not the least of all was how not to get caught.
