Rawlins, Carbon, Wyoming may or may not be his last residence. Social security uses that field for other purposes. I looked his death up in Ancestry but only found the Social Security info.
There is an obituary volunteer at www.gengathering.com. He/she does his/her research at Brigham Young University so might be able to find his obit. You do have to create a user ID and password to enter the above web site but access to the volunteer info is free. He/she is listed under Utah, All Counties. Successful Searching!
