Does anyone have any info on these 2 officers. It is my understanding that they were Detectives for Jess Dunn when he was Chief of Police in Ardmore.

I found Officer Moreheads' Memorial on the officers down website. He was killed by a desperado by the name of Pat O'Day. It says O'Day was later killed by Texas authorities. It doesn't explain how. Bill Guess was my grandfather. And it was told by our family that Bill is the one that shot him. Just wondering where one might clarify this?
