Information provided by his daughter, as there was no obituary:

I just wanted to let you know that my father, Marshall Goddard, passed away from leukemia 10/4/2015.  He passed away peacefully at home with his daughter and ex-wife, who cared for him during his illness. In terms of life details: he worked at the Ballard Post Office for 27 years, had one daughter whom he was very close with, he loved to play bridge and was obsessed with Sudoku. He lived in the Seattle area until his diagnosis in 2014; then he and his daughter moved in with his lifelong friend/ex-wife in Pullman.
