David Timothy Mackie

David Timothy Mackie, 58, passed away peacefully on May 21, 2026, at UNC Medical Center in Chapel Hill, North Carolina, after a courageous seven month battle with acute myeloid leukemia (AML). Born July 18, 1967, in Ayer, Massachusetts, he was the son of the late George K. Mackie, Jr. and Marina A. Autino. He shared an especially close and loving bond with his mother, a relationship that shaped his kindness, compassion, and deep devotion to family. He often credited her as the inspiration behind the devoted and loving father he became to his own children.

Throughout his life, his commitment to family remained central to his character. He is survived by his spouse, Cari Lynn Mackie; his son, Cameron Mackie; and his daughter, Olivia Mackie. His family was the center of his world, and he took great pride in his children, frequently expressing admiration for their character and accomplishments, as well as his excitement for their futures.

He is also survived by his loving sisters, Alexandra Duncan (Ian Duncan) and Elizabeth Capps; his brother, George K. Mackie III; his uncle, Arthur Autino of Phoenix, Arizona; numerous nieces, nephews, and cousins; extended family in Cigliano, Italy; and many friends across the country who were touched by his kindness, loyalty, and generosity.

Among these relationships, his lifelong bond with his sister Alexandra, affectionately known as Sandy, was especially meaningful. Their relationship was marked by shared confidences, enduring support, and a deep mutual understanding. From childhood through adulthood, their connection remained a constant source of strength and companionship. She will carry his memory with her always and feel his absence deeply in the years ahead.

In addition to his devotion to family, David demonstrated dedication and integrity throughout his professional life. He enjoyed a distinguished 25-year career with Fidelity Investments, where he served as a Senior Technical Manager until his retirement in 2021. He was widely respected for his technical expertise, professionalism, and mentorship, and colleagues frequently sought his guidance and valued his thoughtful perspective. In retirement, he devoted more time to his family, friendships, and the simple pleasures of daily life.

David approached his personal interests with enthusiasm and appreciation. A devoted New England sports fan, he followed the New England Patriots with great passion and took particular joy in their recent return to the Super Bowl. He also embraced his adopted home team, the Carolina Hurricanes, following their success with equal enthusiasm and would have celebrated their Stanley Cup win this year eagerly with his son Cameron.

Music was another important aspect of his life. His eclectic taste reflected his thoughtful nature, with Pink Floyd holding a special significance. Their music accompanied him through many moments of reflection and provided both comfort and inspiration. He shared this love of music with his daughter Olivia, who enjoyed many of the same artists and genres, creating a special bond between them.

He also valued time spent outdoors and with friends, particularly on the golf course, where he cherished the camaraderie as much as the game itself. Whether in Massachusetts or North Carolina, these moments were marked by laughter, friendly competition, and meaningful connection.

His love of travel further reflected his appreciation for shared experiences. He especially enjoyed road trips, including a memorable cross-country journey with his family, during which they visited loved ones across the country. His regular trips between North Carolina and Massachusetts were equally meaningful, often including visits to cherished local destinations such as Kimball’s in Westford, Bentley’s in Amherst, New Hampshire and Gold Bowl in Fitchburg.

He found peace in nature, enjoying walks along North Carolina trails and time outdoors in Massachusetts, and he cherished these moments until his health no longer allowed him to continue them. A particularly memorable experience was a hike up Mount Wachusett with his brother-in-law, Ian Duncan, with whom he shared a close and valued relationship. Their mutual interests in aviation, history, and travel enriched their bond and many conversations, and they affectionately called each other “Brotato” and “Bromato,” a reflection of their bond.

In his final months, the care and compassion he received provided comfort to both him and his family. The family extends heartfelt gratitude to the nurses and physicians at the Basnight Cancer Hospital in Chapel Hill, especially Paige and Bailey, whose kindness and dedication brought comfort and moments of levity during his treatment.

In a final journey reflecting his lifelong love of travel and connection to home, he returned from North Carolina to Massachusetts on a final road trip shared between him and his sister, Sandy, where he will be laid to rest alongside his mother and grandparents at St. Mary’s Cemetery in Ayer, Massachusetts on August 15, 2026.

There will be two separate celebrations of life held in honor of David’s life, one on what would have been his 59th birthday, July 18, in North Carolina, and one in Massachusetts. The family will be sharing additional details for the Massachusetts event via social media in the near future.

In lieu of flowers, the family kindly requests that memorial contributions be made in his honor to support leukemia research and patient care.
