Biography
Helen Jean O'Neal McCray was arrested in Jackson, Mississippi, on July 19, 1961 — one of the arrests recorded by the Mississippi State Sovereignty Commission and preserved in the Civil Rights Digital Library. The catalog establishes the arrest, the participation, and the individually identified police photograph, but not the court disposition, any transfer to Parchman, or the physical release date; those fields are unresolved pending county-jail, court, or penitentiary records.
The CRDL biography dates the arrest July 17 while the photograph metadata reads July 19, 1961; the photograph date is entered here and the two-day discrepancy stands unresolved.
