Jack the Ripper unmasked

[Dalia]

How amateur sleuth used DNA breakthrough to identify Britain's most notorious criminal 126 years after string of terrible murders

GUILTY: A DNA sample has proven Polish immigrant Aaron Kosminski was Jack the Ripper


It is the greatest murder mystery of all time, a puzzle that has perplexed criminologists for more than a century and spawned books, films and myriad theories ranging from the plausible to the utterly bizarre.

But now, thanks to modern forensic science, The Mail on Sunday can exclusively reveal the true identity of Jack the Ripper, the serial killer responsible for at least five grisly murders in Whitechapel in East London during the autumn of 1888.

DNA evidence has now shown beyond reasonable doubt which one of six key suspects commonly cited in connection with the Ripper’s reign of terror was the actual killer – and we reveal his identity.

A shawl found by the body of Catherine Eddowes, one of the Ripper’s victims, has been analysed and found to contain DNA from her blood as well as DNA from the killer.

The landmark discovery was made after businessman Russell Edwards, 48, bought the shawl at auction and enlisted the help of Dr Jari Louhelainen, a world-renowned expert in analysing genetic evidence from historical crime scenes.

Using cutting-edge techniques, Dr Louhelainen was able to extract 126-year-old DNA from the material and compare it to DNA from descendants of Eddowes and the suspect, with both proving a perfect match.

The revelation puts an end to the fevered speculation over the Ripper’s identity which has lasted since his murderous rampage in the most impoverished and dangerous streets of London.

In the intervening century, a Jack the Ripper industry has grown up, prompting a dizzying array of more than 100 suspects, including Queen Victoria’s grandson – Prince Albert Victor, the Duke of Clarence – the post-Impressionist painter Walter Sickert, and the former Liberal Prime Minister William Gladstone.

Born in 1864 in Poland, he fled Russian persecution of Jews in 1882 to settle in England. In July 1890 he was sent to the infirmary at Mile End. On the admission records, there is mention of madness for 2 years. Yet he will be put in the custody of his brother 3 days later. In 1891, he was admitted to the Greenfield Street Infirmary and interned at Colney Hatch Asylum. According to some knowledge, he was hanging out in the streets, picking up bits of bread and eating them, never washing himself and drinking unhealthy water. He died in 1919. Little is known about his life, except that he was a barber and practiced in the Whitechapel neighborhood.
In 1890 a witness said he saw Kosminski with one of the victims in a more than suspicious position, and no doubt referred to him as an identification. Unfortunately shortly after he retracts and refuses to testify. This same suspect also appears in the famous memorandum of Mc.Naghten in 1894, which wrote: I quote "He had a great hatred of women and strong tendencies to homicide". Assistant High Commissioner Sir Robert Anderson also indicates in his memoirs that he was the only suspect identified, but that no judicial proceedings were put in place since the witness retracted. Finally Chief Inspector Swanson pointed to a pen in the margin of a copy of Anderson's memoir that it was Kosminski, who had been interned just after the murders, and had died soon after.

Proves nothing.

These victims were hookers.

Just proves the hookers had contact with the Pole.

 

[JakeStarkey]

If he had contact with all five and had a history of hating women, yeah, he is the guy to be looking at hard.

Proves nothing.

These victims were hookers.

Just proves the hookers had contact with the Pole.

Kosminski was 23 when the murders took place, and living with his two brothers and a sister in Greenfield Street, just 200 yards from where the third victim, Elizabeth Stride, was killed. As a key suspect, his life story has long been known, but I also researched his family. Eventually, we tracked down a young woman whose identity I am protecting – a British descendant of Kosminski’s sister, Matilda, who would share his mitochondrial DNA. She provided me with swabs from the inside of her mouth.

Amplifying and sequencing the DNA from the cells found on the shawl took months of painstaking, innovative work. By that point, my excitement had reached fever-pitch. And when the email finally arrived telling me Jari had found a perfect match, I was overwhelmed. Seven years after I bought the shawl, we had nailed Aaron Kosminski.

the DNA found in the stains on the shawl, which means mapping the DNA by determining the exact order of the bases in a strand. I used polymerase chain reaction, a technique which allows millions of exact copies of the DNA to be made, enough for sequencing.

When I tested the resulting DNA profiles against the DNA taken from swabs from Catherine Eddowes’s descendant, they were a match.

The first strand of DNA showed a 99.2 per cent match, as the analysis instrument could not determine the sequence of the missing 0.8 per cent fragment of DNA. On testing the second strand, we achieved a perfect 100 per cent match.

 

[yiostheoy]

It's not proof of anything.

There is strong evidence that the real Jack The Ripper sailed to New York City and began killing there on the anniversaries of his London murders. He was apprehended in New York, imprisoned, and executed.

This is the best explanation of why the Ripper murders suddenly stopped in London. The Ripper sailed away and was caught and executed elsewhere.

There is no reason to suspect that Kosminski had anything to do with it other than he had a liaison with one of the hookers who was later killed.

This is epic!

yiosthey, good stuff.

The DNA means the guy had contact with one of five hookers, and that contact is of no proof.

Yes, as explained by the French scientific police .... nothing is definitive
Jack the Ripper: Is Aaron Kosminski "Guilty"?

Since September 08, 2014, the Daily Mail assures that the British businessman Russel Edwards helped biologist Jari Louhelainen, expert in genetic analysis, broke through the mystery of the identity of "Jack The Ripper"
The news is in many newspapers: Jack the Ripper has been identified! The mystery of Jack the Ripper solved! The killer's DNA speaks 126 years later ... In a book published on September 09, 2014, Russel Edwards explains having formally identified a Polish immigrant, already suspected at the time of the facts, Aaron Kosminski.
On what object did we find the DNA of Jack the Ripper? What is the probability that this DNA trace belongs to the suspect? Many questions arise about the validity and relevance of such identification, 126 years after the fact.


Is this the first time an "amateur" investigator identifies Jack the Ripper?
No. Patricia Cornwell also said in 2002 to be "100% sure" that Walter Sickert, a British painter, was none other than the terrible Jack the Ripper. The author had spent several million pounds in the purchase of Sickert's paintings and personal objects to come to this conclusion. Without any expertise carried out thereafter can definitively confirm his thesis.
Is the author of the revelation (and the book) credible?
According to him, Russel Edwards has been investigating the ripper for 14 years. However, one may have doubts about the quality of the preservation of the exhibit when one sees on some photos or videos, the author manipulate the offending object without gloves or mask of protection. He has just published the book "Naming Jack The Ripper" and the newspaper that relays information from the release of the book, the Daily Mail, is an English tabloid. The revelation therefore takes much less credit in this newspaper than in a scientific journal.
Where does the exhibit come from potentially supporting the DNA of the serial killer?
It all began in March 2007 when 48-year-old British businessman Russell Edwards decided to buy a shawl from a victim of the killer, Catherine Eddowes, at auction. The owner of the garment claims to be the descendant of one of the police officers present at the time on the crime scene: Amos Simpson. He would have recovered the shawl to give it to his wife. The piece of fabric would have been passed on from generation to generation without ever being washed.
At the material time, were the clues or objects removed protected or inventoried? Can we be positive about the provenance of the exhibit?
One can not be in any doubt about the origin of the exhibit. In the murder of Catherine Eddowes, all the objects owned or worn by the victim were listed by the Metropolitan Police but there is no mention of the shawl. Has this been forgotten by the investigators? The many gray areas concerning the originality and authenticity of the exhibit do not support the hypothesis put forward in Russel Edwards' book.


Has the shawl not been contaminated over time? Has the DNA potentially present on the object not degraded over the years?
The shawl had to be heavily contaminated by a large number of DNAs, which had been passed down from generation to generation by the Amos Simpson family. It would have been interesting to analyze the object in all its details to know how many different DNA were discovered on the object. However, in the case of so-called "rich" DNA traces (blood, sperm), it is not impossible to find DNA in these cells many years later, if it is preserved from light, from the heat and moisture.
Is the recovered DNA a mitochondrial DNA or a nuclear DNA?

The DNA found on the shawl was compared with the DNA of the offspring of Kosminski's sister and then "identified" for a match of "99.2% on the 1st strand and 100% on the second strand" of after Jari Louhelainen. In view of these statements and press articles, it therefore seems that the identification would relate to mitochondrial DNA and not to nuclear DNA. If that were the case, how can the biologist make sure that the mitochondrial DNA comes from sperm (which except exception is a biological fluid with very little mitochondrial DNA) and not from external contamination?
Is Kosminski's mitochondrial DNA unique?
Unlike nuclear DNA, mitochondrial DNA is identical in a large number of people. Because the mitochondria of spermatozoa are eliminated at the moment of fusion with the egg, mithochondrial DNA is a purely maternal inheritance. This mtDNA is strictly identical within the same siblings (with some exceptions). At the material time, other individuals could have the same mitochondrial DNA as Kosminski's.
Why did the experts work on mitochondrial DNA?
Sometimes, when nuclear DNA is not present or too degraded, experts work on mitochondrial DNA. There are about 100 to 1000 mitochondria per cell and each mitochondrion contains about ten copies of mitochondrial DNA, which explains that the exploitation of mitochondrial DNA theoretically has between 1000 and 10,000 times more chance of succeeding, especially in the d phase. DNA in very small quantities or very degraded.
What is the scope of this DNA comparison?
Assuming that the shawl comes from the murder of Catherine Eddowes, the discovery of this mitochondrial DNA would reinforce the hypothesis that Kosminski is indeed the author of the facts. But it is impossible to say with certainty that this DNA belongs to Aaron Kosminski.
In order to examine the relevance of Russel Edwards' evidence, it would be necessary to know the frequency of mitochondrial DNA discovered. Today, from existing databases, the frequency of mitochondrial DNA is generally between 0.004% and 5%. Thus, by performing a mitochondrial DNA analysis, it is excluded to be able to affirm that a trace comes from an individual to the exclusion of any other person.

Assuming that Kosminski had very rare mitochondrial DNA and using the low frequency of 0.004%, this would mean that out of the 40 million people in Britain at the time, 1600 people could have the same mitochondrial DNA as Kosminski .
In the same way, if the scientist Jari Louhelainen worked on mirochondrial DNA to identify the victim, the same reasoning is valid. Suffice to say that in view of the possible contaminations, the two DNAs detected could belong to two people outside the case.
From DNA to murderer there is only one step?
At best, if the DNA found on the shawl comes from a trace of sperm left by Kosminski and a trace of blood left by the victim, can we conclude the guilt of Aaron Kosminski so far? Indeed, the circumstances of the case, including the job of the victim (prostitute), can very well explain the presence of traces of sperm. The presence of DNA of an individual on an object in no way proves the criminal act which is only a question of interpretation and moreover the competence of Justice and not of Science.
"After one hundred and twenty-six years, I have definitely solved the mystery," says the amateur investigator. Yet many questions remain unresolved ...

The mystery is certainly not solved, but a big step has been made.

The mystery is certainly not solved, but a big step has been made.

There is a lot of suspects but only one Jack the Ripper, an friend of mine told me and if it was Conan Doyle Jack the ripper?
Because Jack the ripper would have written to the police you are idiots I am there and you do not see me.
This same sentence was found in one of Conan Doyle's Sherlock Holmes books.
