Boni Kay Dye (Mahaffey), “Sissie,” was born on June 27, 1961, in San Diego, California, and passed away on December 21, 2025, in Rapid City, South Dakota, leaving behind a legacy of love, laughter, creativity, and strength.

Boni was a devoted wife, mother, grandmother, and friend whose presence brought warmth and joy to everyone she met. She is survived by her beloved husband, Brian L. Dye; her children, Casey G. Kellum, Jake E. Morton, and Trista K. Hutchinson; and her cherished grandchildren, Imogen J. Anderson, NaKea R. Anderson, Joslynn E. Morton, Canaan A. Morton, Hadley R. Morton, Natalie M. Morton, and Hayden L. Hutchinson, each of whom held a special place in her heart.

Known for her unstoppable work ethic, Boni dedicated nearly 30 years of service to Walmart, where her dependability, determination, and laughable jokes left a lasting impression on coworkers and customers alike. She was a gifted artist who loved crafting and painting, using her creativity as a source of joy and comfort.

Boni had a one-of-a-kind sense of humor and was famous for her well-loved “dad jokes.” She truly loved life and embraced it fully, quirks and all. Along with her creative passions, it gave her pure joy for collecting creepy doll heads, a hobby that perfectly reflected her playful spirit and unique personality. Some of her happiest moments were spent riding Harleys with her husband, enjoying the freedom of the open road and the adventure of the ride.

A celebration of life will be held in late spring or early summer of 2026, where family and friends will gather to honor and remember a woman whose spirit, humor, creativity, and love will never be forgotten. To find more information, see Facebook Events: Boni “Sissie” Dye Celebration of Life.
