David Peter Mathieu, 72, of Grayson, Kentucky, formerly of Massachusetts, departed this life peacefully to be with his Lord at his residence on Friday, March 27, 2026.Born on June 2, 1953, in Fitchburg, Massachusetts, David was the beloved son of the late Ernest and Edna Pinault Mathieu. In addition to his parents, he was preceded in death by his brother, John Mathieu.David was a proud patriot who honorably served his country in the United States Air Force. His dedication to service reflected his steadfast character and deep love for his country. Following his military service, David worked as a maintenance mechanic, a trade perfectly suited to his remarkable talent for understanding how things worked. Known by many as someone who “could fix anything,” David had a gift for taking things apart and putting them back together—whether electronics, engines, or everyday household items. His curiosity and skill were matched only by his patience and determination.David found great joy in life’s simple pleasures. He loved being on his boat and scaring everyone by saying “I never go over 90” and the freedom of the open road on his motorcycle to which he was coursed by his daughter to continue riding. With his signature railroad conductor hat and easygoing style, he was unmistakably himself—earning the affectionate title of the “cool uncle” among his nieces and nephews. Those who knew him will remember his quiet strength, his steady presence, and the way he loved—quietly, but fiercely.Above all else, David cherished his family. He was a devoted father to his daughter, Sarah (Joseph) Gagnon of Grayson, Kentucky, and a proud and loving Papa to Lucas Parker, Nathan Parker, Hudson Gagnon, and Emmett Gagnon. His grandchildren were a source of immense pride and joy, and he treasured every moment spent with them.He is also survived by his brother, Robert Mathieu of Massachusetts; three sisters, Jeannette Albert, Sue McNeil, and Debra Lasorsa, all of Maine; and a host of extended family members and friends who will deeply mourn his passing and carry his memory forward.A Memorial Service will be conducted at 12:00 Noon on Friday, April 10, 2026, at Malone Funeral Home with Military Honors. Friends may call from 11:00 AM until the service hour on Friday, April 10, 2026.Condolences may be shared with the family at www.malonefuneralhome.com.
