A Nairobi court has granted the Directorate of Criminal Investigations (DCI) 14 days to detain police officer Kenneth Kipkeboi Sang as detectives investigate his alleged involvement in the murders of Dr Victoria Nthunya Mutiso and prominent Nairobi lawyer Matthew Kyalo Mbobu.
Sang was arrested in Eldoret over the weekend following an intelligence-led operation before being transferred to Nairobi for further investigations.
The DCI sought additional time to interrogate the officer, record his statement, conduct searches, pursue possible recoveries and complete investigations before making a decision on charges.
The court application outlined evidence investigators believe links Sang to the two killings, although the allegations remain subject to the ongoing investigations and court proceedings.
Firearm Recovered as Detectives Investigate Mutiso’s Murder
According to the investigating officer, detectives recovered a Mini Jericho pistol bearing serial number 47302127, which was subsequently examined.
The DCI told the court that a ballistic report linked cartridge cases and a bullet head recovered during investigations to the firearm.
Investigators further alleged that the weapon had been issued to Sang, making him a prime suspect in Mutiso’s murder.
The application also linked the officer to an earlier incident involving the deceased, who reportedly told police she had been confronted by two armed individuals riding on a motorcycle near Junction Mall along Ngong Road on July 7, 2026.
According to the investigators, Mutiso escaped the encounter and reported the incident at Kilimani Police Station under Occurrence Book number 63/07/07/2026.
Detectives suspect Sang may have been among those involved in planning the alleged attack, although the claim has yet to be determined by a court.
Suspected Accomplices Remain at Large
The DCI told the court that other suspected participants in Mutiso’s murder were still at large, raising concerns that they could collude with the suspect, evade arrest or interfere with potential evidence.
Investigators said Sang was expected to be charged alongside alleged accomplices who have already been charged before the Milimani High Court in Criminal Case No. HCCRC E004 of 2026 in connection with Mutiso’s murder.
The additional detention period is intended to allow detectives to pursue outstanding leads and establish the alleged roles of the individuals under investigation.
DCI Links Sang to Lawyer Matthew Kyalo Mbobu’s Killing
In a separate allegation, investigators claimed Sang played a significant role in the murder of prominent lawyer Matthew Kyalo Mbobu, who was killed on September 9, 2025.
The DCI’s application described Sang as a suspected planner in the killing.
His alleged accomplices have reportedly already been charged before the Kibera High Court in Criminal Case No. HCCRC E019 of 2026.
Detectives are seeking to establish the circumstances surrounding both murders and determine whether the alleged offences involved coordinated planning.
Investigators Cite Flight Risk, Seek Mental Assessment
The DCI also argued that Sang posed a flight risk, alleging that he deserted his workstation after the suspected crimes and went into hiding.
Investigators told the court that the additional 14 days would allow them to question the officer, conduct further searches, pursue possible recoveries and complete outstanding inquiries before processing him for charging.
The DCI further sought permission to have Sang escorted to hospital for a mental assessment before his appearance for plea-taking.
The investigations into the two high-profile killings remain ongoing, with detectives pursuing additional evidence and possible links between the cases.
