Today at the Idaho History Center, I looked through the Twin Falls Times-News for the month and found no obituaries for Jack McCall. That agrees with the online index. I did see in the 1986 Twin Falls Polk City Directory listings for J. C. McCall - retired - 203 Crestview and Jack C. McCall, Jr. - wife Donna B. - v-p Dunford, Moore & Assoc. The 1987 City Directory lists Jack C. McCall, Jr. and Donna B. McCall. I surmise that Jack C. McCall, Sr. is the one you are seeking? Jack C. McCall, Jr. is currently in Twin Falls, per online telephone directories - contacting him may be your easiest source for info.
