Here are my first impressions after reading the first post, the NAMUS report, and this last page of posts.
-No chest hair. While not a definite, that could point to some Native American heritage
-Orthodontic work and appendix scar; middle to upper middle class. Had access to dental and health care.
-Was wearing "northwest" inspired clothing. Plaid shirt, jeans, timberland boots
-Very thin for height. Coroner report suggested he had recently loss 30-40 lbs. of body weight. Depression or illness? Stomach problems...scar on stomach?
-He committed suicide VERY CLOSE TO WHERE KURT COBAIN WAS BORN. Same county. Was he 27 years old like Cobain when HE committed suicide? Was he part of the Nirvana grunge scene that came out of Seattle?
-Maid or someone at hotel suggested he might have had a Canadian accent. Vancouver?
I have to think more deeply on the book, and get a copy to read. I suspect our answer as to who this fellow really is, can be found in those pages.
