I understand it was your opinion.
However, it can help finding if WSB can be a potential match or not.
Because if material evidence are so weak it questions LE's suspicions, match is much more likely.
OTOH, if LE's suspicions are based on strong material evidence, a match is unlikely.
It can rule her out before DNA comparison, but it won't rule her in.
My idea is that before submitting this potential match, let review what kind of evidence LE has against husband.
If evidence against LE is weak, it'll be easier to convince LE to run a DNA analysis
That's a great idea!
