Justin "JJ" Michael Bonvillain

Justin “JJ” Michael Bonvillain, 26, of Walker, Louisiana, passed away on June 16, 2025, in Baton Rouge. Born in Houma, Louisiana, JJ brought light, laughter, and love to every life he touched. JJ was a devoted husband, a loving son and brother, a proud uncle, and a loyal friend. He worked as a railcar mechanic, known not just for his skill and strong work ethic, but for his loyalty to his team and family. However, it was in the little things—outside of work—where JJ’s personality truly shined. He was an avid fisherman who found peace on the water and joy in the stillness of nature. He loved gaming on his PlayStation, often getting passionately invested in every round. He also had an ever growing collection of football cards that he talked about with pride and enthusiasm. And of course, he had his collection of guns—all of which he claimed he “needed.” These things brought him happiness, but more importantly, they brought out his humor, his passion, and his deep love for life’s simple pleasures. At the end of the day, JJ’s greatest joy was his family. He is survived by his loving wife, MacKenna; his grandfather, Allen; his parents, Katrina and Doug; and his sisters, Marianne and Sarah. He also leaves behind his mother-in-law, Crystal; father-in-law, Walter; brother-in-laws, Carson, Kaden, and Dylan; and nephews, Jasper, Everett, Julian, and Brayden—each of whom brought a light to his life and shared in his laughter. JJ is preceded in death by his grandparents, Mike and Mary Valdez; as well as his grandmother, Geraldine Bonvillain. JJ had a heart that was larger than life. He was the kind of person who showed up, who made you laugh when you didn’t think you could, and who loved his people fiercely. Though his time on earth was far too short, the impact he made—the memories he gave, the love he shared—will live on forever in the hearts of those who knew and loved him. Relatives and friends are invited to attend visitation at Christ’s Community Church in Denham Springs on Wednesday, June 25, 2025 from 12:00 PM until services begin at 2:00 PM. Bro. Willis Easley will conduct services. By choosing to be an organ donor, JJ gave an extraordinary gift—one that transcends grief and pain. In giving of himself, JJ became a hero—not just to those who loved him, but to complete strangers who now carry a piece of his spirit with them every day. His legacy continues, not only in the lives he touched, but in the lives he helped save. Arrangements have been entrusted to McLin Funeral Home.
