Three more arrested in Dr Victoria Mutiso murder probe, two suspects nabbed in Uganda

Three more suspects have been arrested over the murder of Dr Victoria Nthunya Mutiso, with two detained in Uganda and another intercepted in Nairobi as detectives deepen investigations into the killing.

According to the Directorate of Criminal Investigation (DCI), the arrests followed forensic analysis by a specialised team investigating the assassination, with the operation covering Nairobi and Kampala.

The team comprised detectives from the DCI Headquarters’ Crime Research and Intelligence Bureau (CRIB), Operations Directorate and Homicide Bureau.

Acting on the forensic findings, the detectives said they travelled to Kyanja Heights flats in the Nakawa suburb of Kampala, where, with the help of the Uganda Police Force, they arrested two suspects who had allegedly sneaked into Uganda after the murder.

They were identified as Police Constable Bett Kiplangat Collins, number 118491, attached to Thogoto Police Station, and Pius Muiru Mbugua, a civilian.

“The National Police Service (NPS) acknowledges the professional support of the Uganda Police Force, whose cooperation made the raid, arrests and secure detention possible. The two suspects are held at Jinja Road Police Station pending an escorted return to Nairobi,” the detectives said.

The same investigation team had earlier intercepted a third suspect, Samuel Karanja Gathoni, also known as “Lawyer”, in the Langata Multi-Media area as he headed towards Ongata Rongai.

Investigators established that PC Bett was assigned to conduct surveillance and acted as co-driver to Daniel Mwangi Njoroge, whom detectives have identified as a central organiser of the operation.

According to DCI, Njoroge was driving the Land Cruiser Prado registration KDH 600A, which was allegedly used to box in the Uber vehicle in which Dr Mutiso was travelling on the morning of July 29, 2026, in Upper Hill, Nairobi, shortly before she was shot dead.

Detectives also established that Mbugua was a key link between the execution team and the person who allegedly contracted them.

Detectives said Mbugua acted as a paymaster and moved money used for logistics and the movement of the alleged hit team.

“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,” the DCI said.

The DCI also thanked Dr Mutiso’s family, friends and relatives, as well as members of the public, for their patience and support during the investigations.

The agency said the support came at a time when some political actors had made what it described as reckless, inflammatory and unsubstantiated claims about the case.

The DCI said the claims included allegations that suspects had been arrested and later released in secret, as well as claims that security officials had helped them escape.

It said the claims were false and were intended to damage the investigation, reduce public trust and portray detectives as accomplices rather than investigators pursuing the suspects.

The agency said the arrests made in Kampala provided a factual response to those claims.

“The DCI will continue to update the public on significant developments as investigations progress and whenever it is operationally appropriate to do so,” it said.

Members of the public with information that could help the investigation have been asked to report to the nearest police station or provide information anonymously through the #FichuaKwaDCI toll-free number 0800 722 203 or WhatsApp number 0709 570 000.

Meanwhile, four suspects accused of murdering Dr Mutiso will undergo mental assessments before taking their pleas.

Angela Mulwa, Rose Mbithe Mulwa, Chris Mulwa and Elijah Kibelion Kimoi appeared before Justice Kanyi Kimondo at the Milimani Law Courts.

The assessment will take 14 days, with Justice Kimondo directing that the suspects should not plead until it is completed.

The four face murder charges under Section 203 as read with Section 204 of the Penal Code. Kimoi will be provided with a pro bono lawyer, while the prosecution plans to seek consolidation of the cases on September 23.

Dr Mutiso was fatally shot on July 29, 2026, with the court previously hearing that she had a pending land dispute in Machakos and had reported being confronted by two armed people on a motorcycle before her death.
