The U.S. Attorney’s Office for the Southern District of Florida held a ceremony in Miami to honor the retirements of Assistant U.S. Attorney Mary V. “Jena” King and Legal Assistant Niurka “Nikki” Machin, both recognized for their long federal service.
Jena King retires after more than 36 years with the office, during which she became known for her integrity and commitment to justice. Her work has influenced many prosecutors and staff members over the years. U.S. Attorney Jason A. Reding Quiñones commented on her legacy: “Jena’s family’s legacy of public service is woven into the very fabric of our community. Every day, we walk through the doors of the King Federal Justice Building—a powerful reminder of her father’s enduring contributions to the bench and to this District. Jena has carried that same spirit forward in her own distinguished service, leaving behind a record of excellence that will continue to inspire those who follow.”
Niurka “Nikki” Machin served nearly 20 years, primarily supporting the Narcotics Section, where she was valued for her reliability and ability to manage complex cases. Prosecutors depended on her steady presence and judgment throughout demanding prosecutions in the district. U.S. Attorney Reding Quiñones said: “Nikki was a constant source of support for our Narcotics Section. She kept demanding cases on track and brought order and professionalism to the most complex cases. She made our mission stronger, and we are deeply grateful for the service she gave this Office and the people of South Florida.”
The event included colleagues, leadership, and law enforcement representatives from the City of Miami Police Department, led by Chief Manny Morales, who joined in recognizing King’s and Machin’s careers as they transition into retirement.
