Remembering Michael Brian Duffy: A Father, Brother, and Loyal Douglas County Civil Servant

Denver, Colorado – April 30, 2024: Michael Duffy, known for his unwavering love for his family and his dedication to service as a Sergeant and 22-year veteran of Douglas County Sheriff’s Office, passed away peacefully on the morning of April 18, 2024, while recovering from a heart attack.

Michael, a proud native of Colorado, grew up in Castle Rock, where he attended public schools and graduated from Douglas County High School. Following in his father’s footsteps, Michael dedicated himself to serving his community through law enforcement, a tradition that runs deep in the Duffy family.

His father, Chief Kevin Duffy, has been a proud member of the Douglas County Sheriff’s Office for over 35 years. Chief Duffy’s commitment to public service and his numerous accomplishments within the department reflect the family’s deep-rooted values of integrity and community engagement. Kevin’s leadership and dedication to improving the lives of those in Douglas County serve as a testament to the Duffy family’s legacy of service.

“Mike’s passing is a tremendous loss for our entire community. He was one of the best investigators I’d ever seen. He also took great pride in finding truth and bringing justice for victims. His career was on the rise, and he had a bright future ahead of him. He was taken much too soon. My heart breaks for the entire Duffy family,” said Douglas County Sheriff, Darren Weekly.

Michael leaves behind a loving family, including his parents, Christine Duffy and Kevin Duffy, who reside in Castle Rock, and his children, Lyndy Martin Duffy, 14, and Connor Andrew Duffy, 11. His sister, Jami Duffy, resides in Denver, continuing the family’s presence across Colorado.

Throughout his life, Michael exemplified dedication and integrity. He began his career with the Douglas County Sheriff’s Office in 2002.  Michael started his law enforcement career working in Detentions, then Patrol, and was a long-distinguished Detective working in both the Special Victims Unit and the Major Crimes/Person Crimes Unit.  Michael worked tirelessly for the victims of crime to help bring closure and justice for every victim and family he worked with.  He served with distinction until his passing. Rising through the ranks, Michael earned the respect and admiration of his colleagues, leaving an indelible mark on the department.

“Life was a puzzle that he knew how to solve, and he walked through his life with certainty, logic, love, and compassion,” said Michael’s Sister, Jamie, reflecting on Michael’s character. Beyond his professional achievements, Michael’s passion for sports and camaraderie left a lasting impression on those around him. From his early days playing football to his enduring bond with his sister, Michael’s warmth and zest for life touched everyone he encountered.

Michael leaves behind a legacy of love and service that will be cherished by his family, friends, and colleagues. His memorial service will be held at Southeast Christian Church on May 3, 2024, at 10:00 am, where all who knew and loved him are invited to celebrate his remarkable life.
