Kenyan police have ropped in Interpol in its bid to arrest killers of former top mental medic Dr Victoria Nthunya Mutiso on July 29, 2026.
As police waded deeper into the matter, a Milimani Court on Friday allowed lawyer Angella Mulwa to walk to her freedom after being detained for 14 days.
Magistrate Joan Mati freed Angella, whose mother Rose Mbithe Mulwa,75 and her brother Chris Mulwa, also an advocate after noting that a Mavoko law court had granted her bond.
Upon her release at Mavoko on August 20, 2026, police re-arrested her and presented her to Milimani on Friday, August 21, 2026, seeking fresh orders to have her (Angella) detained for 14 more days.
However, defence lawyers Danstan Omari and Martina Swiga opposed the bid saying the Milimani court is of equal jurisdiction as Mavoko Law Courts.
On August 20, 2026, a Mavoko law courts magistrate Ms Lilian Kwamboka freed Angella on a cash bail of KES 1 million.
However, Ms Mati reserved her ruling until August 24, 2026, on whether police will be allowed to detain her (Angella Mulwa) for 14 days for investigation to establish her alleged involvement in the murder of Dr Mutiso.
Defense lawyers Danstan Omari and Martina Swiga opposed the fresh police request arguing Ms Mati cannot decide a similar matter that has already been decided by another magistrate of equal jurisdiction.
However, a prosecuting counsel Ms Evelyn Mutisya said the fresh application is different from the Mavoko matter where police are investigating on theft of high-end motor vehicle, demolition and eviction, establish whether there was forgery of a court order in respect of a parcel of land at Mavoko.
Ms Mutisya urged the magistrate to allow police to detain Ms Angella Mulwa for 14 days.
“I hereby reserve my ruling to Monday (August 24), whether to allow police to keep the respondent (Angella Mulwa) for 14 days. Meanwhile Angella will be released from police custody as she had been granted a cash bail of KES 1 million which she has since paid,” Ms Mati directed.
Following that order, Angella walked to her freedom around 5:30pm in the company of her lawyer Mr Omari.
At the same time, fresh court filings reveal that the murder had been planned months earlier, with a KES 300,000 down payment allegedly made to the suspected killers on April 24 for the alleged murder to be carried out.
Meanwhile detectives are widening the manhunt for two police officers wanted over the last month's killing of Dr Victoria Nthunya Mutiso, with investigators enlisting Interpol to help trace the fugitives believed to be hiding in Uganda.
Inspector Kenneth Kipkemboi Sang and Police Constable Bett Kiplangat Collins remain at large as detectives pursue the alleged chain linking suspected financiers, police officers, gunman, driver and motorcycle rider.
Dr Mutiso, a prominent neuroscientist and former Director of Research and Administration at the Africa Institute of Mental and Brain Health (AFRIMEB), was shot dead on July 29, 2026, in Nairobi's Upper Hill area while travelling in an Uber.
The latest court affidavit from the Directorate of Criminal Investigations (DCI) says some suspects remain at large, including “some of whom are senior police officers”.
It says investigators are pursuing several leads before submitting the file to the Director of Public Prosecutions (DPP) for an independent decision on charges.
An investigating officer involved in the intelligence-led search told Justice Gauge that investigators believe Inspector Sang and Constable Collins may have fled to Uganda early this month and that Kenyan authorities have sought help from Ugandan authorities to trace them.
The officer, who cannot be quoted as he has no authority to address press, told this writer in confidence that detectives have also activated Interpol to help locate the two officers.
DCI Director Mohamed Amin earlier said Inspector Sang, then serving at Nderi Police Post, was allegedly the link between the financiers of the killing and operational team while Constable Collins was attached to Thogoto Police Post.
Court papers say his firearm was used in the killing and it was found at the Nderi Police Post armoury.
The firearm had allegedly been issued to Sang, while ballistic examinations linked it to cartridges recovered from the crime scene and the bullet retrieved from Dr Mutiso.
The documents says investigators recovered a Mini Jericho pistol linked ballistically to cartridge cases and a bullet head recovered after the killing.
The fresh documents also indicate that Inspector Sang was in communication with lawyer Angella Mulwa, who was also arrested over the killing.
"She (Angella Mulwa) has been in constant communication with Kenneth Sang a senior police officer whose firearm S/No 47302127 which had been issued to him was used to commit the offence," says Corporal Romana Oduor, an investigator, in an affidavit.
Another officer, Police Constable Elijah Kibelion Kimoi, attached to Karinde Police Post, is accused of firing the fatal shot.
The affidavit also says lawyer Angella Mulwa was allegedly present on April 24 when KES 300,000 was paid as a down payment for the planned killing.
“She was present on April 24, 2026, during payment of KES 300,000 down payment for Dr Mutiso to be murdered which failed to materialise,” the affidavit states.
The investigator, attached to the DCI Homicide Investigations Bureau, alleges Ms Mulwa was also present during the eviction and demolition of a property linked to Dr Mutiso in Machakos.
Corporal Oduor also says the lawyer was in constant communication with Inspector Sang, whom investigators describe as a senior police officer.
The fresh application was filed on Friday after lawyer Mulwa was re-arrested on August 20, shortly after being released on bond by the Mavoko court. The court had ordered her release on a Sh1 million bond after rejecting a prosecution request for seven more days.
The lawyer and Nelson Masiga had been released on KES 1 million bonds, with conditions requiring them to surrender passports, remain within the court’s jurisdiction and report to investigators when required.
The new application seeks 14 more days to hold Ms Mulwa at Industrial Area Police Station while detectives complete the murder investigation.
Investigators say Ms Mulwa is known to material witnesses, including members of Dr Mutiso’s family and people connected to the Machakos land dispute. They argue her release could lead to interference with witnesses or collusion with suspects at large.
The affidavit links the murder inquiry to the property, known as LR No. 1504/13, which is before the Machakos court. Detectives say the dispute “might be one of the motives for killing the Dr Mutiso".
The property dispute had appeared in earlier detention applications involving lawyer Mulwa’s mother, Rose Mbithe Mulwa, and brother Chris Mulwa. Police allege the dispute was followed by eviction, demolition and theft of vehicles.
Court papers also reveal that investigators are examining Dr Mutiso’s earlier reports of threats. On July 7, she told police that two armed men on a motorcycle confronted her near Junction Mall along Ngong Road.
“She managed to flee and later she made a report at Kilimani Police Station vide OB No. 63/07/07/2026,” the fresh affidavit says.
The officer adds that before the fatal shooting Dr Mutiso had also reported that she was being trailed.
Dr Mutiso was killed 22 days later while travelling in motor vehicle KDJ 609D in Upper Hill. Investigators recovered two spent cartridges and two bullet fragments for forensic examination.
The new affidavit says forensic work also involves CCTV footage, call-data records and several vehicles and a motorcycle. The vehicles listed are KDJ 609D, KDH 600A and KDE 400W, while the motorcycle is KMGZ 980D.
The evidence is being examined alongside the alleged roles of three suspects already in custody.
Three other people in custody include a police constable attached to Karinde Police Post, who is accused of firing the fatal shot, a civilian who was driving the black Toyota Prado that allegedly blocked the car that Dr Mutiso was travelling in, and another civilian of transporting Kimoi on a motorcycle.
Detective Oduor says the investigation remains “active and intelligence-led”, with several leads still outstanding.
The fresh affidavit names two earlier miscellaneous murder files involving Rose and Chris Mulwa and Constable Elijah Kibelion Kimoi, Daniel Mwangi Njoroge and Kelvin Ngugi Kinuthia. Investigators say other accomplices remain on the run.
The investigators want time to complete technical inquiries, submit the file to the DPP and obtain an independent decision on whether charges should be preferred and merged.
The investigation has moved beyond Kenya’s borders. Their whereabouts remain unresolved as detectives trace the firearm, communications and vehicles.
The new court filing does not establish that any respondent committed the murder. It records what investigators say they have found and the inquiries they still need to complete before prosecutors make their final decision on charges.
