I plan to do that. Aren't you that lady that is researching females sheriff's? If so I met you before Christmas at the Oklahoma History Center. I did look for this same person in a 3 month time frame. I'm sure we will have to broaden our search.
A relative that lives in Mangum, said she remembers seeing a headstone at Riverside Cemetery that says murdered on it. She's hoping to find it again to see if it is Wiley Shaw. He does not show up on a listing of the cemetery but might in the cemetery book which I think the city has at their office.
When I find something in the future, I will post an update.
