I would like to confirm that Graysmith had a friend name Fay Nelson. I was looking at the killing map that my suspect drew for me , he drew 7 in SF and 2 in Daly City. So I looked for cold cases in that city and found another "nurse" 26yrs old ,the date shows Dec 25th 1976. Not sure if that was the date she was killed for sure, or when it was announced? But still close to a holiday, no sexual assault ,strangled in her apt.at 2703 Sutler St.

I was looking at anything I could find for her , I found that Robert Graysmith was her friend or had a friend with that same name? Could she be a Z victim and Z knew she was friends with Graysmith? I know that Graysmith has changed names in his books, so maybe by chance he happened to just use that name as his friend?
