Sandra Kay Hequet Walker

Contemporary issues of The Auditor identify Sandi Mehr as Clear 332 and a Class VI Auditor working in the Boston franchise. A 1968 Hubbard lecture refers to her participation in Royal Scotman missions. Family testimony records the title Supercargo; a crew roster confirming that title has not been located.

Later records place Sandra “Sandi” Walker in Maine. In 2006, a published letter from Orneville Township carried the signature “Sandra Walker (Prairiestar).” A 2025 auction catalog attributes a birch-bark basket with beadwork to Prairiestar Walker and records Potawatomi affiliation and roll number 12094, matching the identifier held in the family record.
