You should check out the following website to be able to view death certificates, and some birth certificates on the archives website for Utah.
Go to http://www.historyresearch.utah.gov/
Then click on the menu option called "Subject Guides"
Select "Death Records"
Then click on the link for Death Records from 1905-1955
Then click on the index link.
Run a search on that page with last name first, first name.
A good majority of these records have a link back to the image of the death certificate.
