John Mark Smith, passed away peacefully on December 15, 2025, in his hometown of Springfield, IL. Born on September 28, 1934, John's 91 years of life were a tapestry of service, dedication, and warm memories that will be treasured by all who knew him.
John's journey began in the same community it ended, instilling in him a profound sense of belonging and purpose. At the heart of this community were his cherished family members, who survive him: his daughter, Kathryn L. (Tony) Spain; his son, Mark A. Smith; his adored grandchildren, Dominic J. Smith, Danielle R. (Boris) Perez de Corcho, Tony R. “TJ” (Trista) Spain, Jr., and Jamie N. (Cliff) Long; and his treasured great-grandchildren, Josh (Becky), Zane, Henry, Valentine, Levi and Silvia; great-great grandchildren, Brooklyn and Ronan. A constellation of nieces, nephews, and cousins also share in the legacy of love he leaves behind.
He was preceded in death by his parents, Frank Irvin Smith and Emelia (Marker) Smith; his first wife, Florence E. (Nizzio) Smith; his second wife, Mary A. (Sponsler) Smith; granddaughter, Heather Shepherd; sister, Clara Lou Bennett and brother, Irvin “Irv” F. Smith.
John's early years laid the foundation for a life of integrity and wholesomeness. He was a proud graduate of Feitshans High School. He then met the love of his life, Florence E. Nizzio and married her on November 6, 1954.
He was called to serve his country in the United States Army, following the Korean War, serving time in Germany.Following his service to the country, he continued his studies at Springfield College in IL, earning his degree in Law Enforcement and was a graduate of the U of I – Springfield, graduating in 1977.
He joined the Springfield Police Department in 1957, starting as a patrolman. Through his dedication and a deep-seated desire to serve his community, he ascended the ranks to become a Sergeant and then a detective. His career culminated with the role of watch commander before retiring after 31 years of distinguished service. His devotion extended beyond the call of duty when he chose to retire early to care for his beloved first wife, Florence, during her battle with cancer in 1989.
The spirit of service remained a constant as John later continued his work with the State of IL at the Department of Revenue. His subsequent roles within the State further demonstrated his versatility and commitment until his second retirement after 15 years. He also found companionship in Mary A. Sponsler and married her on December 31, 1991. They shared many years together before she passed away on October 16, 2006.
A man of faith, John was a long-standing member of Concordia Lutheran Church. His involvement in the IL Police Association, IL Police Benevolent and Protective Association and status as a proud lifetime member of the NRA were testaments to his dedication to his beliefs and community. As a man whose ethos was deeply in tune with the natural world, he relished traveling to the mountains with his family for camping adventures, as well as basking in the Florida sunshine where he pursued his passion for fishing, both on the tranquil pier and in the vastness of the deep sea.
John Mark Smith lived a life marked by an intriguing mixture of grit and selflessness, with a relentless courage that was admired by all. Described by those who knew him best, John's enduring spirit will remain a guiding light to his family, friends, and all the lives he touched.
