I checked the Western States Marriage Index but she wasn't listed there.
I found a Bessie Turner who died 2/12/1952 in Blackfoot, Bingham Co., ID per death cert #542.

She's buried in Twin Falls Cemetery, Twin Falls, Twin Falls Co., ID; Section 83 Lot: 13 Grave: 1. Her birth date isn't listed.
One way to find out if this Bessie was yours, is to find her obituary (if one was published). You can contact The Morning News, http://www.am-news.com/
Also the 1940 Census has been released to the public but the indexing isn't complete yet for Idaho. To check on when the indexing will be complete, go to familysearch.org.
