Jeffrey Lee Treadway

December 20, 1985 ~ September 26, 2025

Jeffrey L. Treadway, 39, Sioux Falls, SD, passed away peacefully on Friday, September 26, 2025, surrounded by loved ones at the Dougherty Hospice House in Sioux Falls, after a very short battle with cancer.

Per Jeffrey’s wishes he will not have a funeral service and instead will have his ashes spread at Pikes Peak in Colorado and a place he always wanted to visit…Japan.

In lieu of flowers, the family asks that you honor Jeffrey’s memory by enjoying a game, a movie, or a quiet moment with loved ones.

Jeffrey Lee Treadway was born on December 20, 1985, in South Dakota to Rick Fenicle and Holly Howard. He was a kind and beautiful soul with a passion for gaming, anime, food, and the worlds of Marvel and DC. His love of computers and fascination with Japanese culture shaped much of his life and brought him joy, curiosity, and connection.

Though his health often limited his opportunities, Jeffrey was a devoted and loyal worker when he was able, and he carried that same loyalty and kindness into his relationships. Those who knew him best will remember his quick wit, easy smile, his gentle heart, and the way he found comfort and community in the things he loved. Jeffrey is deeply loved and will be forever missed by his dad, Rick, mom, Holly, and stepmom, JoAnna; his brother, RJ Fenicle; sister, Sierra Fenicle-Eveland and brother-n-law, Tim Eveland; brother, Stephen Fenicle; and sister, Molly Fenicle; his grandmothers; aunts; uncles; Godfather, Jon Dewaard; as well as many friends; and his special friend, Jennifer.
