The only information (as released to the media) the police have sofar
is he is white ,
aged 30 to 50 and may live in London, Surrey, Kent or Berkshire.
But they do have the suspect's DNA profile.
So how come they are only swabbing 3000 targets to find a match.
Buried in these DNA profiles is an indication of the person's
ethnic background. I know from my own DNA profile just
concerning the alleles (numbers) on just 2 of the 10 loci (markers)
ie D18S51 and D16S51 I or anyone else would know I was 20
times more likely to be white than black (true). With the computer
and data systems available to the police I am sure there
are combinations that would similarly give a greater likelihood
of being say Greek or Polish or Zambian origin or whatever. From that
construct a list of surnames of that origin. Especially if this
rapist's
profile has thrown up a rare locus/allele combination.
The PNC Boolean computer search would then be

(men on PNC for sex crime now aged 30 to 50) AND (never been DNA
profiled )
AND (living in one of the 4 counties) AND (having surname relating
to ethnicity)

It is the last factor that seriously cuts down the possibilities.
There is a specific
gene that expresses as red hair for example . Given a
complete DNA sample is available there are more and more physical
characteristics that are becoming discernable with medical research.
In the obsessive genealogy (family history) groups there are
people taking DNA samples and profiling the different branches
of their own families. Now when this data gets cross-referenced to PNC
computers then there is real big brother sort power. Unfortunately
the police will have to swab all active and past milkmen in
this country to make full use of the facility.


Further investigation on DNA profile matters towards end of my file
