It is true or false that Jack killed in complete darkness?
Also, if he did kill in complete darkness and mutilated the bodies, wouldn't he have had to know what he was doing like how to cut and take out a certain organ? Do you believe Jack had any anatomical knowledge or surgical ability?
Read this and let me know what your thoughts are on it. Some doctors said Jack had some anatomical knowledge and others didn't. What do you think. If it is true that Jack killed and mutilated in complete darkness, it would make sense he would have known where to cut.
Generally, surgeons who viewed the killer's victims at the crime scene felt he had a great deal of anatomical knowledge and some experience in butchering with a knife. Surgeons who handled the bodies of the victims in the mortuary were not as sure. However, we can answer that question by looking at what the Ripper did and how he did it.
The Ripper used a long, sharp knife, but he did not just cut anywhere; autopsy surgeons repeatedly pointed out that there were no extraneous cuts, meaning every cut had a purpose and was set just where the person wielding the knife intended it to be. No damage was done to the surrounding tissue when organs were removed. That does not sound remarkable unless you put it into the context of the time and place; in the first two murders (Nichols and Chapman), the Ripper worked in near-total darkness, yet had no difficulty in identifying organs and removing them without damage. Today, even with our anatomy training and rudimentary health knowledge, the average person would probably be unable to do that, let alone do it in a short time with the constant threat of discovery.
In Catherine Eddowes` murder, he removed the uterus and one kidney. Even today, finding that kidney would not be easy, yet the killer found it and removed it. The killer had some light for Eddowes` butchering, but not a great deal; it would still have been difficult to do. The theory that the killer just happened on the kidney is improbable; it would have been difficult to find even if the killer was looking for it. It was also very important to note that the killer was probably working within a very short time limit, and had only a few minutes to find and remove the kidney. It is probable that he had decided to remove one before he targeted and killed his victim.
You must remember the Ripper was working in near-complete darkness, butchering a body in a public site where could be discovered at any time, and probably limited by a time constraint he had set. He had to watch his own back at the same time he was working on the body. He probably was watching the time, knowing that police patrols or other chance individuals might show up at any time. He performed these dissections quickly, even savagely, with no improper cuts or damaged tissue and in bad lighting or in near darkness. He must have been practiced in that sort of thing, so it would have been reasonable for him to have worked as a slaughterman or butcher at the time.
There was an excellent article that looked at the lighting conditions in Mitre-square when Eddowes was murdered. It appeared in Ripperologist issue no. 58, 2005, and was also reprinted in Ripperology, Barnes and Noble, 2007, Paul Begg, (Ed.)
It was written by some bloke called Neil Bell and was entitled Jack by Gaslight: The Problem of Illumination in Mitre-square.
