Where is Sang? Key suspect remains missing as another cop linked to Dr Mutiso's murder seized in Uganda

One of the police officers on the run and linked to the murder of Dr Victoria Nthunya Mutiso has been arrested while in hiding in Kampala, Uganda.

Police Constable Collins Kiplangat Bett was smoked out of Kyanja Heights flats in Nakawa suburbs of Kampala on Saturday by a special team from the Directorate of Criminal Investigations (DCI) headquarters.

Kiplangat has been on the run for four weeks following the July 29, 2026 cold-blooded murder of Dr Mutiso, a clinical psychologist, who was ambushed in Upper Hill while heading to work.

The rogue officer was seized at the apartment alongside his accomplice, identified as Pius Muiru Mbugua, a Kenyan civilian who investigators say was the key link between the execution team and the person who contracted the killer squad.

According to DCI, Muiru served as paymaster, moving money for logistics and movement of the hit team.

For one month, the team from DCI headquarters’ Crime Research and Intelligence Bureau (CRIB), Homicide Bureau and Operations Directorate has been on the trail of Kiplangat and his senior Inspector Kenneth Kipkemboi Sang, who remains on the run.

Kiplangat, Kipkemoi and Police Constable Elijah Kibelion Kimoi were directly linked to the murder. Kibelion, who was arrested about two weeks later after the incident, is said to have fired the fatal shot that ended the life of Dr Mutiso, who was at the time the head at Africa Institute of Mental and Brain Health.

Arrested alongside Kiplangat and Muiru is Samuel Karanja Gathoni, alias Lawyer. The suspect was nabbed around the Multi-Media University area in the outskirts of Nairobi as he headed towards Ongata Rongai.

Investigators say the latest three arrests are a breakthrough in the probe into the murder of Dr Mutiso.

 “Acting on forensic analysis, the team proceeded to Kyanja Heights flats in the Nakawa suburb of Kampala. With the assistance of the Uganda Police Force, they arrested two suspects who had illegally sneaked into Uganda after the murder,” said DCI in a statement adding credence to earlier claims by former

Deputy President Rigathi Gachagua that police officers Kipkemboi and Kiplangat had been aided to sneak into Uganda.

According to the former DP, the two rogue officers had initially been arrested but released unconditionally after Interior Cabinet Secretary Kipchumba Murkomen called Directorate of Criminal Investigations boss Mohamed Amin. Inspector Kipkemboi was allegedly seized within Thogoto while Constable Kiplangat was arrested on his way to Momabasa around Mazeras.

“We are asking Mr Amin, these officers are in Kenya; they are killers; they have killed Dr Mutiso, and you have confirmed they participated in the murder, why then are you releasing them after Murkomen called you,” stated Rigathi, who was the first to blew the whistle over the involvement of police officers in the murder.

After being arrested, Kiplangat and Muiru were taken and detained at Jinja Road Police Station transfer to Nairobi.

“The suspects arrested in Uganda are being prepared for escort to Kenya, where all three will be processed and arraigned in accordance with the law. Flight delayed the file. It did not close it,” said DCI yesterday.

Civilians earlier arrested and already in court are Daniel Mwangi Njoroge and Kelvin Ngugi Kinuthia, are in custody for participating in the murder.

Mwangi was the driver of the Prado registration KDH 600A used to block the taxi. DCI boss Amin said he coordinated logistics, facilitated the movement of the execution team, and played a key organisational role in the conspiracy. While Ngugi was identified as the rider who ferried the shooter to the scene.

Following the latest arrests, detectives have revealed that Kiplangat was tasked with a surveillance role and served as Mwangi’s co-driver.

The DCI extended gratitude to the family, friends and relatives of Dr. Mutiso, and to members of the public, for the overwhelming patience and steadfast support they have extended to detectives.

 “That confidence made these investigations possible at a time when some political actors, hungry for cheap political mileage, chose to flood the airwaves with reckless, inflammatory and unsubstantiated claims.

 “They peddled propaganda and rumour that the suspects had been arrested and quietly released, and that security officials had facilitated their escape. Those assertions were false. They were calculated to smear the investigation, shake public trust and cast detectives as accomplices rather than pursuers. Yesterday’s arrests, effected in Kampala, are the factual answer to that noise,” said the DCI.

The DCI promised to continue updating the public on significant developments as investigations progress, and whenever it is operationally appropriate to do so.

The whereabouts of Kipkemboi remain unknown. The DCI is appealing to members of the public for information that may lead to his arrest.

Kipkemboi, the officer in charge of Nderi Police Post in Kikuyu of Kiambu County was identified as the link person between financiers and the operational team assembled to eliminate Dr Mutiso. The senior officer provided the murder weapon – a Mini Jericho pistol loaded with 12 rounds of ammunition.

Kiplangat was attached to Thogoto Police Station while Kibelion was based at Karinde Police Post.

Dr Mutiso was in taxi when the car encountered a black Toyota Prado that had partially blocked the road. Victor Chunguli, the driver of the Uber taxi told investigators that he slowed down before noticing a person seated at the left rear window open fire.

The bullets struck Dr Mutiso, who was pronounced dead on arrival at Kenyatta National Hospital, where the mother of two had been rushed.

Detectives believe the killing was motivated by a long-standing land dispute that is the subject of a civil case at the Machakos Law Courts.

Also in court in connection with the murder are Rose Mbithe, her two children, Chris Mulwa and Angela Mulwa. Mbithe was the former wife of Professor David Musyimi Ndetei who later remarried Dr Mutiso.

Before the murder, Mbithe and her two children, both lawyers, had been fighting to evict Dr Mutiso from prime land in Mlolongo.
