A quote from the article in The West Virginian below…
“Here was a man who killed his wife and her lawyer in cold blood, and then killed himself. Before that he devised an ingenious plan to destroy his home by fire. He chiseled the words, ‘Hell’s Half Acre’ on the steps leading to his property and he called his power boat “Hell’s-a-poppin.’ He kept a grotesque figure of a woman before him at the table and he may have been motivated by his horoscope… Yost was of solitary disposition, inclined to brood, prejudiced against persons of other races. An introvert… He apparently developed a persecution complex. He felt that the world was against him.” – The West Virginian, date unknown.
