Method of Operation
Surprisingly, a full understanding of the Ripper's modus operandi was not established until several years ago. The Whitechapel murderer and his victim stood facing each other. When she lifted her skirts, the victim's hands were occupied and was then defenseless. The Ripper seized the women by their throats and strangled them until they were unconscious if not dead. The autopsies constantly revealed clear indications that the victims had been strangled. In the past some writers believed that the Ripper struck from behind when the victims were bent forward, their skirts hiked up their backsides while waiting to engage in anal sex. This is a very awkward arrangement and the risk that they may scream or elude his clutch's make this unacceptable. The Ripper then lowered his victims to the ground, their heads to his left. This has been proven by the position of the bodies in relation to walls and fences that show that there was virtually no room for the murderer to attack the body from the left side. No bruising on the back of the heads shows that he lowered the bodies to the ground rather than throwing or letting them fall. Given the inclement weather and filth in the streets it is unacceptable that the prostitutes or their client would have attempted intercourse on the ground. He cut the throats when the women were on the ground. 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. In one case blood was found on the fence some 14 inches or so from the ground and opposite the neck wound and this shows that the blood spurted from the body while in the prone position on the ground. This method also prevented the killer from being unduly blood stained. By reaching over from the victim's right side to cut the left side of her throat, the blood flow would have been directed away from him, which would have reduced the amount of blood in which he would have been exposed. If the victim was already dead before their throats were cut, then the blood spilt would have not been very much. With the heart no longer beating the blood would not have been "pressurized," so only the blood in the immediate area of the wound would have evacuated gently from the cuts. The Ripper then made his other mutilations, still from the victim's right side, or possibly while straddling over the body at or near the feet. In several cases the legs had been pushed up which would have shortened the distance between the abdomen and the feet. No sign of intercourse was ever detected nor did the Ripper masturbate over the bodies. 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. Given the time circumstances of the crimes (outside, often in near total darkness, keeping one eye out for the approach of others, and under extremely tight time constraints), the Ripper almost certainly would have had some experience in using his 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. A letter dated September 25 and received on the twenty-seventh by the Central News agency was the first to be signed "Jack the Ripper". A postcard post marked October 1 followed. Because it referred to a "double event" the police thought it might be from the killer since it was posted the day after the Ripper killed two women. The post card also referred to the letter and must have come from the same source as the letter had not been released to the public yet. If the post card had been sent on September 30, the day of the "double event", instead of October 1, the likelihood that it was really written by the murderer would be significantly greater. The Whitechapel Murderer may have written the letter/post card but there is no evidence to suppose that he did and the police seem convinced that they were the work of a journalist. A recently discovered document states that a journalist from the Central News agency, Tom Bulling, was the writer.
One other letter may have been written by the killer. In mid-October a small parcel was sent to George Lusk, who was head of a vigilance committee in Whitechapel. Inside was half a human kidney and a letter from someone claiming to be the killer, and that it was part of the kidney he removed from the victim Eddowes. It is impossible to know for sure if the Ripper really did send it. Most of the arguments in favor of it being from Jack have been based on inaccurate information and the myths rather than the facts surrounding the case. However, Eddowes did suffer from Bright's disease and the description of the kidney does match what a Bright's disease kidney would look like.
Evidence
In a time before forensic science and even finger printing, the only way to prove someone committed a murder was to catch either him or her in the act, or get the suspect to confess. The Whitechapel Murders unhappily fall into this period of time. One interesting feature of this case is that not one, but two police forces carried out investigations. The Metropolitan Police, known as Scotland Yard, was responsible for crimes committed in all the boroughs of London except the City of London proper. The single square mile in the heart of London known as the City of London had their own police force. When Eddowes was killed, it was in their territory and this brought them into the Ripper case. It is believed that the rank and file of the two forces got along and worked well together, but there is evidence that the seniors in each force did not. To what degree, if any, their failure to cooperate fully had on solving the case is not known. Most sources do not fault either police force for failing to solve the Jack the Ripper mystery, rightly pointing out that catching serial killers is still a hard task even by today's science and technology. Other than autopsies and taking statements from everybody who might know something there was little else that the Metropolitan police force did. The attitude of the people at the time was that the police were incompetent and that the Commissioner, Sir Charles Warren, was only good for policing crowds and keeping order rather than detective work. He was especially criticized for not offering a reward in the hope that a confederate or accomplice would come forth and inform against the Ripper. In fact, Warren had no objections for a reward being offered and it was his superior, Henry Matthews, the Home Secretary who refused the sanction of a reward. The City of London Police seems to have done a better job although they did not apprehend the killer either. City police officers made crime scene drawings, took many photographs of the victim Eddowes, and even though she was not in their jurisdiction, they took photographs of the Kelly victim. She is the only victim who was photographed at the crime scene. One of the splits between the leadership of the two forces was over graffito found in Goulston Street on the night of the "double event". A piece of Eddowes' apron, which the Ripper used to wipe off his knife, was found by a constable near a doorway that had a chalked message over the door. This message, "The Juwes are the men That Will not be blamed for nothing", may have been written by the Ripper and the City police officers wanted to photograph it. Warren felt that leaving it until it was light enough to be photographed might cause riots against the Jews living in Whitechapel whom the bigoted English residents already believed were responsible for the murders. Warren did not even compromise by willing to erase or cover up the word "Juwes" only. In the end the police never charged any suspect with the murders committed by the Ripper which shows they did not have a sufficient amount of evidence that would gain a verdict of guilty in criminal court.
