I am trying to locate the grave site of my grandmother's brother, Elda James McCollum. He was born February 14, 1910 in Boyle, MS and was murdered January 22, 1936 in or near Mangum, OK where he is supposedly buried. I have a photo of my Great-Grandparents and the finger printer who identified his remains, at his grave site. The back of the photo is stamped: Jimmie's Studio Mangum, OK
Any suggestions on cemeteries in the area that I could possibly contact?
