Leibowitz led Commissioner Moody and Jackson County Circuit Clerk C.A. Wann through every page of the Jackson County jury roll to show that it contained no names of African-Americans. When, after several hours of reading names, Commissioner Moody finally claimed several names to be of African-Americans, Leibowitz got handwriting samples from all present. One man admitted that the handwriting appeared to be his. Leibowitz called in a handwriting expert, who testified that names identified as African-American had been added later to the list, and signed by former Jury Commissioner Morgan.
