Probably should have added this to the original post as there are some new folks in the group. There are two Facebook groups with more info on the DB Cooper case in general.

The evidence is conclusive that the stamp on the Clara envelope sent to Ralph Himmelsbach was very likely licked by a woman named Dolores Kislowski. There is a slight chance that it could have been licked by a sister, or someone very close.

Dolores Kislowski was the wife of William J. Smith. What made this match somewhat easy to decipher is that the DNA profile was from a nearly 100% Polish woman.

I am evaluating options on publishing this information in a professional journal vs a newspaper.

The pic is an evaluation of the shared centimorgans of people who matched the DNA on the stamp. This pic is of someone who matches at the highest level.
