Do a google search for "Artell Farley" and select "news" on the far left, then select "archives," again on the left, a little lower down on the page. There are several articles about the case there. Google News Archive is a great (& largely free) resource, but it's kind of a pain to search. This is the best way I've found to do it.
Alternately, if you do a lot of genealogy research, Genealogy Bank is definitely worth the subscription. I've found a lot of great info there, especially old newspapers and more recent obituaries.
Let me know if you have any difficulties. I've got to go now, but if you need I'll send you some links later on.
Best of luck,
