I found this article on line under Lily Gray:
Elmer L. Gray's Criminal Pardons Application is now available online via the Utah State Archives. What a character. Reading his answers in the form questionnaire, a definite sense of his personality can be detected, which includes sarcasm ("Woodrowe Lamb, a bum,") irony, and exaggeration. He seems quite eccentric, and probably more than a bit cantankerous.
In the document, he has typed a line that has an affinity with and shares a spirit with the one on Lilly's stone. On the line that asks for "Address of parents," Mr. Gray has written, "Booth dead. Died of grief when kidnapers murdered my Wife." Later, he refers to his arresting officers and prison officials as "Democrat officials," and "kidnapers."
So, whatever the real circumstances concerning these family deaths, it can be concluded that Elmer Gray blamed the law for the death of his previous wife and clearly considered her a victim. (Remember, Lilly was a subsequent wife-they married in 1950, three years after this document was filed.)
Elmer Gray's view of the government and law is clear-a criminal, evil organization hell-bent on kidnapping, imprisoning and murdering innocent citizens without cause or provocation.
With all the conspiracy, anti-government, sentiments of victimization within, it is difficult and perhaps foolish not to come to one conclusion-that Elmer L. Gray was responsible for placing the outrageous phrase, "Victim of the Beast 666" on his second wife Lilly's gravestone, and that it refers simply to the government, law enforcement and officials, with whom he likely tangled with his entire adult life*, and the dynamics and beliefs based on his experiences.
So, after reading the Criminal Pardons Application, and considering his references to victimhood and murder at the hands of the law; also that he was Lilly's only known survivor, who likely made all her funeral arrangements, including ordering her stone-what are the chances that the inscription has nothing to do with his extreme belief system?
Although an investigation into the apparently colorful life of Elmer L. Gray is unquestionably warranted, I believe the mystery behind his wife's strange epitaph is finally solved.
