Welcome to Websleuths! You may want to become a Verified Insider (VI) so you can share what you know without prefacing it as your opinion. If your best friend is able to participate, he/she could also join the thread, perhaps? If you need info about becoming a VI, you can use the report option to ask a moderator for help.
It's a wonderful thing you are doing and I hope the great contributors here are able to help you solve the mystery of what happened to Edith.
She happens to be born the same year as my paternal grandmother, so that caught my eye!
I am curious about the following:
+ Her maiden name & her ex-husband's name.
+ Are her sons still living? Were they her only children? What are their names?
+ Because of the LA Times story shared here, I am wondering if her sons, grandchildren, neighbors, friends, etc., talked to the media? Maybe there are other stories with clues?
Is there a police file with any info or research that can be shared here? From other cases posted at WS, comparison with NAMUS records of unidentified bodies (UIDs) can help. DNA can also help with the search of UIDs.
I have no particular expertise except general research skills. But I hope this forum can help you find Edith.
MOO
