Politician Rose Mbithe Mulwa, her two children and two police constables have been charged with the murder of city lawyer Mathew Kyalo Mbobu.
The Director of Public Prosecutions (DPP) announced the charges on Tuesday, October 27, 2026, after the five suspects were arraigned before the Kibera High Court.
“The five accused persons were arraigned before the Kibera High Court, where they were charged with the murder of Mbobu,” the DPP stated.
The accused persons, Rose Mbithe Mulwa, her children Chris Mulwa and Angela Mulwa, and police constables Julius Kipkoech Cheruiyot and Kennedy Kipkemoi Borboroi, appeared before Lady Justice Diana Kavedza and pleaded not guilty to the charges.
According to the particulars of the charge, the five allegedly murdered Mbobu on September 9, 2025, at approximately 7:30 p.m. along Magadi Road in Karen, within Lang’ata Sub-County, Nairobi.
The charge states that the accused persons acted “jointly with others not before the court” in the alleged killing.
The case marks the second murder prosecution involving Rose Mbithe Mulwa and her two children, who are also facing charges in connection with the murder of psychiatrist Dr Victoria Nthunya Mutiso.
The prosecution also informed the court of its intention to charge Police Inspector Kenneth Sang in connection with Mbobu’s murder.
Sang was arrested in Eldoret on Saturday and presented before the Milimani Law Courts on Monday, October 26, 2026, where investigators secured a 14-day detention order to complete their inquiries.
The DPP said the detention period would allow investigators to interrogate the suspect, record his statement, conduct searches, pursue possible recoveries, facilitate a mental health assessment and complete investigations before charging him.
“The court granted the 14-day detention period to allow investigators to interrogate the suspect, record his statement, conduct searches, make possible recoveries, facilitate a mental health assessment and complete investigations before charging him,” the prosecution stated.
Sang was ordered to be detained at Kilimani Police Station, with the case scheduled for mention on November 9, 2026. Investigators have linked him to both Mbobu’s killing on September 9, 2025, and the murder of Dr Mutiso, who was fatally shot in Nairobi on July 29, 2026.
Dr Mutiso was a former director of the African Institute of Mental and Brain Health. Court proceedings in the investigation into her killing revealed that detectives recovered two spent cartridges and two bullets from the scene.
A ballistic examination reportedly linked the recovered ammunition components to a Mini Jericho pistol that was subsequently recovered and examined. Investigators established that the firearm had been issued to Sang.
The prosecution alleges that Sang played a key role in planning Mbobu’s murder. He has not yet been charged in the case, according to the information provided.
Following the arraignment of the five suspects, the Kibera High Court directed the prosecution to file an affidavit opposing their release on bond.
The court scheduled November 24, 2026, for the hearing of the bond application. Until his death, Mbobu served as an Advocate of the High Court, university lecturer and author.
The five accused persons have denied the murder charge, and the allegations against them remain subject to determination by the court.
