If I were in your shoes, I would expect that your question has a slim-to-no chance of finding an answer in this way -- and I'd start by contacting Yelm's City Hall, the city records section which holds birth, marriage and death records. I'd start the fascinating search for info there.
With that date of death, then I'd contact the Nisqually Valley News for an obituary which might have been published.
I would also contact Thurston County records, checking the recorded history of the house which might offer some additional leads.
You'll have the person's age from the death information, so you can do the math and contact local high schools to see if there's a yearbook picture.
There might be additional public information available through the newspaper, Chamber of Commerce, City Hall, churches, etc., and the fun of finding out is the adventure of following your own creativity! Have fun!
