I thought possibly the alias mentioned in attached article could be of some help......he was arrested in MO in 1953 and then by 1954 was in CA.
The article with the alias is from The Joplin (MO) Globe 04 Jun 1953 and the other article is from The Redwood Journal Press Dispatch (Ukiah, CA) 07 Apr 1954 - he was sentenced later that day to the State Prison.
I found this in the Social Security Death Index - this could be him - the year of birth & the civil in MO would seem to fit:
b 25 Feb 1920
d 07 Dec 2006 Cottonwood, Yavapai, AZ
Civil - Missouri
Death certificates can cost as much as $50 & take a long time. Do you have access to Ancestry? If you do, click on this SSDI info and to the left of the screen there is a place where you can generate an automatic letter to Social Security. He would have had to fill out his original application himself & put his parents' names there. The cost is $15 or $27 depending whether you get the short or long version of his application......
If you think this may be the Truman you are looking for and don't have access to Ancestry I can get the letter for you.... please email me direct at firstname.lastname@example.org
I could only find one Truman b 1920 MO in the census but he is listed clearly as Truman E.
