Nexus and provenance
Hi Mick,
For me the key issues in all of this long saga are nexus and provenance. Thus, applying the most favorable interpretation of the evidence, let us accept provisionally that Eddowes' genetic material is on the garment together with other genetic material relating to Kosminski's mtDNA. What would that actually prove? I mean, assuming that around 90.000 Londoners in 1888 shared Kosminski's haplogroup, why would it be any more likely to be his genetic material than any one of the other 90,000 individuals?
What is required is something more. Firstly, clear provenance regarding the scarf so that we can at least postulate that the genetic material may have been deposited in 1888. Secondly, some nexus connecting Kosminski directly to Eddowes or another victim.
As regards provenance, this is virtually non existent, relying on some story about Amos Simpson and the shawl that appears to have been passed down through the ages like some generational Chinese whispers.
As regards nexus, it seems to me that all we have at the moment to connect Kosminski to the murders is an unreliable identification, possibly but not necessarily at the Seaside Home, of some one who may or may not have been Kosminski, by an unreliable witness, possibly Lawende, but maybe not, several years after the event!
