Who was Jack the Ripper?
Jack the Ripper
"Jack the Ripper" is the popular name given to a serial killer who killed a number of prostitutes in the East End of London in 1888.
The name originates from a letter written by someone who claimed to be the killer.
The killings took place within a mile area and involved the districts of Whitechapel, Spitalfields, Aldgate, and the City of London proper. He was also called the Whitechapel Murderer and "Leather Apron".
Why is Jack the Ripper so Famous?
Several factors combined to help make this series of crimes famous all over the world. One being that the newspapers of the day gave a huge amount of coverage to the crimes and provided their readers with daily updates on them with the result that Jack the Ripper effectively became a menacing media figure.
Finally, there was, of course, the name by which the killer came to be known - Jack the Ripper. It was this name - which was probably the invention of a journalist - that had the effect of turning five sordid East End murders into an international phenomenon and of catapulting the unknown miscreant responsible into the realm of legend.

Secondly, the area in which the killings occurred was perceived as being a hotbed of vice and villainy, and a breeding ground for social unrest, squalor and disease. The Whitechapel Murderer came to be seen as the personification of all the evils with which the East End of London was associated.
Modus Operandi
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.

The Ripper 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.
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. 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 split 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.


Modus Operandi Continued
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.
Usually he took a piece of the victim's organs. 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 taking of a "trophy" is a common practice by modern sexual serial killers. No sign of intercourse was ever detected nor did the Ripper masturbate over the bodies. This is known because you can use Acid Phosphatase presumptive tests to see if semen was present anywhere. 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 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. It was also thought that the Ripper almost certainly would have some experience in using his knife since he was able to remove the sexual organs with one clean stroke of the knife.

THE LETTER READS:

Dear Boss,
I keep on hearing the police have caught me but they wont fix me just yet. I have laughed when they look so clever and talk about being on the right track. That joke about Leather Apron gave me real fits. I am down on whores and I shant quit ripping them till I do get buckled. Grand work the last job was. I gave the lady no time to squeal. How can they catch me now. I love my work and want to start again. You will soon hear of me with my funny little games. I saved some of the proper red stuff in a ginger beer bottle over the last job to write with but it went thick like glue and I cant use it. Red ink is fit enough I hope ha. ha. The next job I do I shall clip the ladys ears off and send to the police officers just for jolly wouldn’t you. Keep this letter back till I do a bit more work, then give it out straight. My knife’s so nice and sharp I want to get to work right away if I get a chance. Good Luck.

Yours truly

Jack the Ripper

Dont mind me giving the trade name

PS Wasnt good enough to post this before I got all the red ink off my hands curse it No luck yet. They say I’m a doctor now. ha ha

(Jones, Richard.)
Edwards had DNA testing done to a shawl that was reportedly found on a victim in 1888 and claims he found a match with a descendent of Aaron Kosminski, an original suspect in the case.

Jari Louhelainen, a molecular biology professor at Liverpool John Moores University, performed a number of tests on the shawl and said he found a "perfect 100 % match," according to the column.
From a criminal law perspective the chain of custody leaves a lot to be desired,meaning that for this to stand up in a court of law there would need to be documentation that established where the shawl was at all times and who has had access to it.
(Grisham, Lori)
The scientist who conducted a DNA analysis of the shawl found near the body of one of Jack The Ripper’s victims allegedly made a basic error, which means the identity of one of history’s most notorious killers is in doubt again.

How Forensic Science Could Have Solved the Case
DNA Evidence?
There are many ways that forensic science could have solved the Jack the Ripper case.
Photographs
DNA profiles
Presumptive Test
First, the shawl has been "openly handled by loads of people and been touched, breathed on, spat upon," This means that the genetic material could be contaminated. Also, most labs working on ancient DNA do so with blind samples—researchers don't know which samples are which—to prevent their biases from affecting results. Labs also go to great lengths to ensure those samples are not contaminated. None of this as far we know, has been done in this case.
(Nuwer, Rachel)
If photographs would have been taken of all the crime scenes I'm sure we would have a better idea of who Jack the Ripper actually was. The photographs could have helped the investigators see/remember things at the scene that they didn't notice or specifically remember.
In general, if the investigators would have followed the rules and regulations for crimes then a lot less errors would have been made, and more progress.
DNA profiling has been used in the Jack the Ripper case but it was the first ever case that used profiling, so we can be sure DNA profiling has improved a lot since then.
DNA profiling is the analysis of DNA from samples of body tissues or fluids in order to identify individuals. (Durham)
A Kastle–Meyer Presumptive Test ( the test to see if blood is present at the crime scence) should have been done at the crime scene before anything was removed. If the investigators would have done this then they would have realized that Catherine Eddowes' shawl would have been a huge help to figuring out who exactly Jack the Ripper is.
