The brutal shooting of clinical psychologist and mental health researcher Dr. Victoria Nthunya Mutiso near Raila Odinga Highway was initially treated as a targeted hit by professional assassins. However, as the Directorate of Criminal Investigations (DCI) unraveled the plot, the public was met with a terrifying reality: the hitmen were serving officers of the Kenya Police Service.
Promised a contract payout of Ksh 1.5 million, officers stationed at local police posts transformed state-issued weaponry and authority into tools for murder-for-hire.
Anatomy of the Hit Squad: Breakdown of the Rogue Pipeline
Investigators believe the conspiracy brought together wealthy financiers and compromised police leadership to execute a clean hit with minimal immediate trace.

EXECUTION & SURVEILLANCE
Raila Odinga Highway Ambush
1. The Broker in Uniform
Inspector Kenneth Kipkemboi Sang, the Officer Commanding Nderi Police Post under Kikuyu Police Station, served as the bridge between civil dispute financiers and the operational trigger-men. According to DCI Director Mohamed Amin, Inspector Sang provided the murder weapon and negotiated the logistics. Sang remains on the run.
2. The Trigger-Man
Police Constable Elijah Kibelion Kimoi, attached to Karinde Police Post, was identified through ballistic matches and surveillance footage as the shooter. Shell casings recovered from the crime scene directly matched PC Kimoi’s issued firearm.
The Shadowy Web: Land Disputes, Stolen Cars, and Previous Unsolved Hits
The conspiracy extends far beyond a single shooting. DCI detectives have connected Dr. Mutiso’s assassination to a broader web of high-stakes land conflict:
The Property Conflict: The primary motive stems from a multi-billion-shilling estate dispute involving Rose Mbithe Mulwa (ex-wife of Dr. Mutiso’s husband, Prof. David Musyimi Ndetei).
Recovered Vehicles: Police raids in Karen and Machakos uncovered over 40 mobile phones alongside luxury vehicles—including a Range Rover reported stolen months earlier during a forced eviction.
The Lawyer Mbobu Connection: Homicide detectives are re-examining the September 2025 murder of attorney Matthew Kyalo Mbobu, who previously represented Prof. Ndetei in land litigation against Rose Mbithe. Detectives suspect a single hit squad may be behind both assassinations.

What This Case Means for Police Integrity and IPOA Oversight
The involvement of an Officer Commanding Police Post (OCS-level inspector) in contract killings raises urgent questions regarding police accountability and vetting in Kenya:
Firearm Traceability: How was a state-issued police weapon diverted for private hire without triggering internal armory red flags?
Command Structure Vetting: What oversight mechanisms exist to prevent station commanders from misusing police post resources for criminal enterprise?
Role of IPOA & DCI: While the DCI’s swift action in apprehending suspects is notable, the Independent Policing Oversight Authority (IPOA) faces mounting pressure to audit stations linked to systemic corruption.
