The Directorate of Criminal Investigations has placed rogue police officers at the centre of the meticulously planned assassination of psychiatrist Dr Victoria Nthunya Mutiso.
He revealed that a serving police inspector allegedly linked the financiers to the killers and supplied the murder weapon.
In a detailed written account issued on Friday, DCI Director Mohamed Amin (Pictured below) said investigations had established that Dr Mutiso was shot dead in broad daylight by an execution team whose operation involved two Toyota Prado vehicles, a motorcycle, a serving police officer who allegedly pulled the trigger and another officer accused of facilitating the operation.
The revelations once again put the National Police Service under scrutiny over the involvement of serving officers in serious crimes.
The DCI said the killing of Dr Mutiso, a former Director of the African Institute of Mental and Brain Health, was not a random attack but a carefully planned assassination arising from a long-running land dispute.
Dr Mutiso was shot on the morning of July 29, 2026, shortly after she left her apartment in Tanga Heights for work.
According to the DCI, an Uber driver, Victor Job Chunguli, had accepted a ride request from Dr Mutiso and was taking her from Tanga Heights Apartment on Bamboo Lane off Riara Road to the Africa Institute of Mental and Brain Health at Mawensi Garden off Matumbato Road in Upper Hill.
At about 9.23am, while driving through the Mawensi area, Chunguli encountered a black Toyota Prado which had partly blocked the road.
As he slowed down, the driver heard gunshots coming from the rear left side of the vehicle, where Dr Mutiso was seated.
The driver then saw a man wielding a pistol and shooting at his passenger.
He immediately sped away, manoeuvring around the Prado, and drove Dr Mutiso to Kenyatta National Hospital in an attempt to save her life.
She had suffered three gunshot wounds.
She was pronounced dead shortly after arrival.
The incident was subsequently reported at Kilimani Police Station under OB No. 35/29/07/2026 at 11.24am.
But what initially appeared to be a straightforward murder investigation has now turned into a disturbing account of an alleged criminal network involving civilians, hired vehicles and serving police officers.
The DCI said its Kilimani detectives initially handled the case before the investigation was taken over the same day by the Homicide Investigations Bureau.
The homicide team was reinforced by officers from the National Police Forensic Laboratory, the Criminal Research and Intelligence Bureau and other specialised units.
Two spent cartridges were recovered from the scene while a bullet head was later recovered during the post-mortem examination.
The exhibits were submitted to the National Police Service Forensic Laboratory for analysis.
According to the DCI, forensic examinations, CCTV footage and intelligence operations led investigators to two key suspects, Daniel Mwangi Njoroge and Kelvin Ngugi Kinuthia.
The investigators allege that Njoroge was the central organiser of the operation.
He allegedly drove one of the Toyota Prado vehicles used to block the Uber vehicle carrying Dr Mutiso immediately before she was shot.
The DCI said the two Prados used in the operation were identified through CCTV surveillance as registration numbers KDE 400W and KDH 600A.
The vehicles were allegedly hired out to Njoroge on July 27, two days before the killing, and returned on July 30, a day after the assassination.
Tracking data, according to the DCI, placed both vehicles at the scene of the murder.
Kinuthia, meanwhile, has been identified as the alleged rider who transported the shooter to the scene.
The DCI said he has been forensically placed at the scene.
The motorcycle, registration number KMGZ 780D, has since been impounded.
But it is the alleged involvement of serving police officers that has given the investigation a particularly disturbing dimension.
The DCI says interrogation of Njoroge and Kinuthia generated evidence that led investigators to three serving officers who allegedly played different roles in the conspiracy.
Inspector Kenneth Kipkemboi Sang, the Officer-in-Charge of Nderi Police Post under Kikuyu Police Station, has been identified by investigators as the alleged link between the financiers and the operational team.
More seriously, the DCI alleges that Sang was the source of the firearm used to kill Dr Mutiso.
He is currently on the run.
The officer accused of pulling the trigger has, however, been arrested.
No. 91232 Police Constable Elijah Kibelion Kimoi, attached to Karinde Police Post under Kikuyu Police Station, has been identified by investigators as the man who fatally shot Dr Mutiso.
Another officer, PC Bett Kiplangat Collins of Thogoto Police Post, also under Kikuyu Police Station, has allegedly been forensically placed at the scene.
He too is on the run.
The DCI described the alleged involvement of the officers as a “grave betrayal” of the police uniform and public trust.
The investigation then took an even more damaging turn when detectives recovered what they believe was the murder weapon.
Investigators visited Nderi Police Post and inspected the armoury steel box.
Inside, according to the DCI, they recovered a Mini Jericho pistol, serial number KP 47302127, together with a magazine containing 12 rounds of 9mm ammunition.
An examination of the Arms Movement Register showed that the firearm had been issued to Inspector Sang.
The weapon was subjected to ballistic examination at the National Police Service Forensic Laboratory.
The DCI says the ballistic examination positively identified the Mini Jericho pistol as the weapon used to kill Dr Mutiso.
The two spent cartridges recovered from the murder scene and the bullet head recovered from Dr Mutiso’s body during the post-mortem were said to have matched test-fired specimens from the firearm.
The weapon allegedly supplied by a serving police officer had therefore, according to investigators, been scientifically linked to the murder.
The DCI says the motive for the killing was a long-standing land dispute.
Investigators have linked the murder to Civil Suit No. ELC/E111/2025 filed by Rose Mbithe Mulwa at the Machakos Law Courts.
Dr Mutiso had placed a caveat on land parcel LR No. 1504/13, situated within Mlolongo in Athi River Sub-County.
The DCI says the action was perceived as a direct threat to the interests of parties involved in the ownership and control of the property.
The matter is also being investigated by DCI Mlolongo under Inquiry No. 14/2026.
The investigation has brought Rose Mbithe Mulwa and her son, Christopher Mulwa, also known as Chris Mulwa, into the centre of the police theory of the murder.
The DCI alleges that the two were the primary organisers and financiers of the conspiracy.
Investigators allege that they played a central role in conceptualising, directing and facilitating the operation that culminated in Dr Mutiso’s murder.
Both have been detained as investigations continue.
The DCI, through the Office of the Director of Public Prosecutions, moved to the Chief Magistrate’s Court at Milimani on July 31 seeking authority to continue detaining Mulwa and her son.
The application was made under Article 49(1)(f) and (g) of the Constitution and Section 36A of the Criminal Procedure Code.
The court granted the investigators 21 days to complete what the DCI described as critical inquiries.
The development is particularly significant because Rose Mbithe Mulwa is the former wife of the deceased’s husband, Prof David Musyimi Ndetei.
The DCI says the couple divorced in 2001.
Investigators have also uncovered what they regard as a potentially crucial warning sign preceding the assassination.
On July 7, 2026, Dr Mutiso was allegedly targeted by two unidentified men riding a motorcycle.
The incident occurred along Ngong Road near Junction Mall.
According to the DCI, the two men pointed a gun at her and attempted to shoot her.
She managed to flee and reported the incident at Kilimani Police Station under OB No. 63/07/07/2026.
She was referred to Riruta Police Station but, according to the DCI, she never proceeded there to make a further report.
Twenty-two days later, she was shot dead.
The revelation raises questions about whether the earlier incident was connected to the final assassination and whether opportunities existed to identify and stop the people targeting her.
The DCI has described the murder as a cold-blooded and meticulously planned operation.
Investigators say the killers did not leave the execution to chance.
Vehicles were allegedly hired in advance.
The road was blocked.
A rider allegedly ferried the shooter.
The shooter allegedly used a firearm supplied by a serving police officer.
Another officer has allegedly been linked to the operation, while the DCI says a senior officer acted as the link between the financiers and the operational team.
CCTV footage, vehicle tracking data, forensic examinations, ballistic evidence and intelligence operations have consequently formed the backbone of the investigation.
The DCI says it is still pursuing additional leads.
And there is another chilling dimension to the investigation.
Detectives are examining leads suggesting that some of the suspects connected to Dr Mutiso’s murder may also be linked to the September 9, 2025 drive-by shooting of lawyer Kyalo Mbobu along Magadi Road.
The allegation, if established, would suggest that investigators may have stumbled upon a wider criminal network operating beyond the killing of Dr Mutiso.
For now, however, the DCI says investigations remain active.
The Directorate says it intends to establish the role of every person involved, whether as financier, organiser, supplier of the firearm, shooter, rider, surveillance operative or facilitator.
The revelations are likely to reignite debate over accountability within the National Police Service.
The alleged role of Inspector Sang is particularly troubling because the DCI says the firearm used in the killing was officially issued to him and was subsequently recovered from the armoury of the very police post where he served.
The alleged participation of PC Kimoi and the alleged presence of PC Collins at the scene further deepen the questions facing the Service.
The issue is not merely whether individual officers committed a crime.
It is also whether police firearms, intelligence, access and institutional networks can be exploited by criminal interests to plan and execute assassinations of citizens.
The DCI has promised that no one will be spared.
“No one — regardless of status, uniform or influence — is above the law,” the Directorate says.
That declaration will now be tested by the investigation and, ultimately, by the courts.
For the family of Dr Mutiso, however, the official account provides a grim explanation of how a respected mental-health professional could be intercepted in traffic, shot three times and killed in an operation investigators say was professionally organised.
For the police, it is another moment of reckoning over rogue elements within the uniformed service.
And for the public, the case raises an unsettling question: if serving police officers can allegedly provide the weapon, facilitate the operation and pull the trigger in a targeted assassination, who can Kenyans trust to protect them from the very people entrusted with protecting them?
