The Directorate of Criminal Investigations (DCI) has made a significant breakthrough in the case of lawyer Mathew Kyalo Mbobu's murder with the arrest of a police constable suspected of involvement in the fatal shooting. Police Constable Julius Cheruiyot was apprehended following extensive investigations into the incident that occurred on September 9, 2025, along Magadi Road in Nairobi. Mbobu was attacked while driving home from work, a crime that has remained unsolved for over a year, leaving his family and the legal community in shock and mourning.
In a statement released on September 24, 2026, the DCI revealed that detectives had recovered a Ceska pistol from Constable Cheruiyot. This firearm, which had been issued to the officer, was subjected to ballistic tests that confirmed it was the weapon used in the shooting that claimed Mbobu's life. The recovery of the pistol and the subsequent confirmation of its use in the crime provided investigators with a crucial piece of evidence, strengthening the case against Cheruiyot.
The investigation into Mbobu's murder has also uncovered potential links to another high-profile case: the killing of Dr Victoria Nthunya Mutiso. Dr Mutiso was shot dead in Upper Hill, Nairobi, on July 29, 2026. According to the DCI, Inspector Kenneth Sang, who remains at large, allegedly coordinated the operation that led to Mutiso's death. Rose Mbithe, currently in custody over Mutiso's murder, is believed to have been involved in both cases, suggesting a possible connection between the two killings.
The DCI has deployed specialised homicide detectives and forensic experts to unravel the circumstances surrounding Mbobu's murder. The agency has expressed its commitment to pursuing all individuals suspected of involvement, irrespective of their rank or affiliations. In their statement, the DCI extended condolences to the families, friends, and colleagues of both Mbobu and Mutiso, acknowledging the profound impact of their deaths on the community.
As the investigation continues, Cheruiyot remains in police custody, undergoing processing ahead of his arraignment in court. The DCI has assured the public that investigations are ongoing, with detectives actively pursuing further leads to establish the motive and full circumstances surrounding the killings. The arrest of Cheruiyot marks a pivotal step in the pursuit of justice for the victims and their families, as the DCI intensifies efforts to bring all perpetrators to account.
