Was Aaron Kosminski Jack the Ripper?
Short answer: not quite sure
Long answer: This is a great case to think about how the
source of information affects its believability, and how readers like us can
make sense of a world where information is King but we can’t tell if the King
is Truthful or not. It’s a question of the criteria we use to make judgments
about who, and what, to believe.
The case: Russell Edwards has in his possession a shawl
reported to be that of Jack the Ripper victim, Catherine Eddowes, who was killed
just after 1 am in a public square near Whitechapel. Her throat was slit, her
face mutilated, and parts of her bowels ripped out of her body. Nasty stuff.
The stuff of legend, fiction, movies, books, and others’ fame and fortune.
Owning a scarf purported to be from the scene of this crime is one thing, but
Russell Edwards, a businessman and author, had it tested for mitochondrial DNA
in a bid to find forensic evidence to lead to the murderer’s identity. Mitochondrial
DNA is DNA found within the mitochondria, a component of our body’s cells. Mitochondria are the site
of energy production – like a power generating station. How this cell organelle
came to contain DNA in the first place is intriguing in itself – it is thought
that the organelle was once an independent living bacteria that was ingested by
a larger unicellular organism that was the ancestor of all animals. But that’s
an aside. The main point is that mDNA is useful in determining relatedness; it
is only passed down from mother to daughter and it is relatively stable from
generation to generation. Also, it can be sequenced from very small quantities
of organic matter.

Russell
Edwards enlisted the help of a molecular biologist, Jari Louhelainen, who found mDNA on the shawl that was a
perfect match to an ancestor of Aaron Kosminski. Aaron Kosminski, a poor Polish
immigrant who ended up in a psychiatric hospital two years after the Ripper murders,
was one of several main suspects in the case. The conclusion is that someone
with Aaron Kosminski’s mDNA left cells on that shawl. Edwards broke the news
that he had the first proof that Kosminski was the Ripper.
The
problems: Not everyone has jumped on Edwards’ bandwagon. Naysayers have had plenty of comment. They point out that the shawl was not mentioned at the time of the murder,
and its connection to Catherine Eddowes is not definitive. They also point out
that ancestors of Kosminski have handled the shawl, so the mDNA found might not
belong to Aaron himself, but one of his descendants. Or, it might indicate that
Aaron had contact with Eddowes, like any number of people living in that area
at that time might have. And, they point out that Aaron was not
institutionalized until nearly two years after the last Ripper murder, and his
mental illness does not seem to match the m.o. of a slasher and dasher.
However,
one of the most interesting issue relating Edwards’ findings, in my mind, is
how he announced it: the evidence was not submitted to a scientific journal for
peer review. Normally, scholarly work is reviewed by two people in the field
who look for holes in the work, alternative explanations to explain the result,
for faults in methods or statistics, or anything else that might make it
suspect. The system is not perfect, by
any means. For one, sometimes two people in a field resist a new idea that
threatens current understanding. Sometimes they miss something. Sometimes, the
scientist(s) writing the paper have outright lied. The evidence of Kosminski
and the shawl, however, was announced to The
Daily Mail, a British newspaper whose pages are heavily filled with murder,
divorce, and celebrity gossip.
Personally,
I love the paradoxes inherent in this controversy. When the news first broke,
media reports spoke of the DNA evidence as relatively convincing. I went to
Wikipedia for more information, and there found a much more balanced view of
the story, with plenty of background information and more than enough reason to
put doubt in my mind of the definitive proof of this new evidence.
Wikipedia
is not generally considered a reputable source, and some teachers frown on its use in a bibliography. And yet, in my own work as a popular
science author, in reading thousands upon thousands of scientific journal
articles and reputable books published by reputable publishers, sometimes
tracking down minute pieces of information few seemingly care about, I’ve
learned that the credibility of sources are often fuzzy.
I
use Wikipedia, and I’m not ashamed to admit it. It often has excellent quality
information written in an understandable way, in a breadth that is hard to
match. However, I always check with secondary sources for agreement – the more
important the info, the more sources I check. And I tend to look up, read, and
cite the references used in Wikipedia in my work. There is some hypocrisy in
our society’s view of Wikipedia as an unacceptable source of information, when
books – compilations of information from elsewhere is deemed acceptable. It has
amazed me to find a single piece of information, say an anecdote about the
first hairdresser in history, Monsieur Champagne of 18th century
Paris, repeated in numerous books all referencing each without any reference to
empirical evidence. So I treat information I read in books the same as I do
information I read on Wikipedia. I use other clues to help with my judgement of
its accuracy.
There
is also the amateur status of Russell Edwards, which is front and centre in the
media that influence judgement of this evidence. Amateurs tend to be dismissed
as sources of information, and yet there are some amateur enthusiasts who have
great breadth of knowledge in a particular area. I recall one particularly
‘obsessed’ amateur scholar of a group of tiny ocean creatures, foraminifera,
who was the go-to person for identification. Amateurs may not carry the same
biases that people entrenched in a field might. In a sense, Henry Ford was an
amateur, so was Alexander Bell. Training does not always make someone smarter or better. What is interesting about
this case is that Edwards’ release of his new evidence coincides with the
release of his book, . Edwards is not just enhancing our understanding of
history, he’s not just an amateur sleuth, he’s a businessman, and he’s profiting.
His motives make his information suspect. The motives behind any source of
information can be highly influential and should at all times be considered in
any case where the truth is important. This is the basis of propaganda.
I’ve
also read enough peer-reviewed scientific papers to know that it sometimes
reviewers and authors and experiments and statistics paint an inaccurate
picture. This is not criticism – it a valid, even important part of the science. It is disturbing,
however, to notice that it is easy to believe information of any kind if it is presented as
having a scientific basis. Science alone is not truth. Science is an endeavour of human
beings. It is, however, generally founded on dedication to finding
and understanding reality as closely as possible. It is the best we’ve got when
it comes to understanding the natural world, including Traditional Knowledge –
which is based on empirical observations passed down from generation to
generation.
All
of which does naught to help clear up whether Edwards’ new mDNA evidence is
enough to proclaim the Ripper identified. The waters of this murder case are
still muddy with doubt, with good reason. Which brings up another aspect of
science in the news: just because something is not proven does not mean that it
is false. The statement, “there is no conclusive evidence that Aaron Kominski was
Jack the Ripper” is not the same as “Aaron Kosminski was not Jack the Ripper.”
He might have been, we just don’t know enough to say so yet. I
should say, I don’t know enough to believe so yet.
