Justin Cadieux, 36, passed away on August 13, 2026. He was born on October 13, 1989, in Ware, Massachusetts, a son of Daniel Cadieux and Laurie (DeSantis) Cadieux.

On September 10, 2011, Justin was united in marriage to Heather Collins. Together, they were blessed with four children, who were the center of Justin’s world.

Justin grew up in Massachusetts for most of his young life before later moving to Fort Mill, South Carolina. Justin, Heather, and their children eventually made their home in Irondale, Missouri, where they purchased a farm and built their home together.

Justin loved being outdoors and could often be found hunting, fishing, or riding dirt bikes, especially when he was able to share those things with his children. His children were his greatest joy, and the memories they made together will forever be a treasured part of his legacy.

Justin was extremely talented when it came to rebuilding motors, including bike motors and motors of all kinds. He was an exceptionally hard worker who took great pride in caring for his family and his land. After a full day of work, he could often be found tending to the farm—whether planting a garden, collecting honey from his bees, or working the land with heavy machinery. Justin found purpose in working with his hands and building a life for his family, and his four children will carry on the legacy he worked so hard to create.

Those who remain to cherish Justin’s memory include his wife, Heather Cadieux; his four children, Elleni, Gemmini, Viktor, and Anberlin; his parents, Dan and Laurie Cadieux; his sister, Meaghan Cadieux; paternal grandmother, Virginia “Memmie” Cadieux; maternal grandmother, Mary DeSantis; father-in-law and mother-in-law, Greg and Cathy Collins; as well as many dear friends.

Justin was preceded in death by his paternal grandfather, Andre “Pepe” Cadieux.

In honor of the family’s wishes, there will be no formal services held at this time.

DeClue Funeral Home was honored to care for Mr. Justin Cadieux’s family during this difficult time.
