Miriam Ngina Muli, one of the longest-serving senior women in Kenya’s police service, retired in February 2025 after a 38-year career that saw her rise to become Principal Deputy to the Deputy Inspector General (DIG) of the Kenya Police Service.
Muli, who served as a Senior Assistant Inspector-General (SAIG), was among the senior officers working at the Kenya Police Service headquarters at Vigilance House in Nairobi.
The National Police Service (NPS) identified her in its official newsletter as the Principal Deputy to then-DIG Eliud Lagat.
Her career placed her close to the top leadership of the Kenya Police Service. According to Nation, Muli, who retired at the age of 60, had served as a deputy to four different Deputy Inspectors-General during her career.
Muli's responsibilities included supporting the DIG on matters relating to police operations and administration.
Her position also placed her in senior command and management meetings involving the leadership of the National Police Service.
A significant part of her career was spent in police training. Reports on her retirement indicate that she spent many years at the National Police College, Main Campus in Kiganjo, where she was involved in training and mentoring police officers.
Her experience in training and personnel management became an important part of her contribution to the service, particularly as the Kenya Police Service continued efforts to strengthen professionalism and leadership among its officers.
The National Police Service also documented her participation in senior police engagements.
In its July-September 2024 newsletter, Muli was listed among senior officers accompanying then Acting Inspector General Douglas Kanja during official engagements.
She was identified alongside DIG Eliud Lagat, Director of Logistics Peter Ndung'u, Director of Personnel Jacinta Muthoni and NPS spokesperson Resila Onyango.
Muli's retirement was marked by a farewell ceremony at Vigilance House attended by Interior Cabinet Secretary Kipchumba Murkomen and other senior officials.
The event brought to an end nearly four decades of service in the country's national security establishment.
Her departure subsequently led to changes in the office of the Kenya Police DIG.
In March 2025, Patrick Tito, who had been the Nyanza Regional Police Commander, was transferred to Vigilance House and appointed Principal Assistant to DIG Eliud Lagat. The appointment followed Muli's retirement the previous month.
Tito's new position involved advising the DIG on operational matters and supporting the running of the Kenya Police Service. His appointment effectively filled the senior position previously occupied by Muli.
Muli's retirement therefore marked the end of a notable chapter in the Kenya Police Service, particularly for women who have risen through the ranks of the country's security sector.
Her 38 years in service included senior leadership, police training and close involvement with successive DIGs, making her one of the most experienced women to have served in the senior ranks of the Kenya Police Service.
