The Directorate of Criminal Investigations (DCI) has said it has commenced comprehensive investigations into the circumstances surrounding the death of former Cabinet minister and ex-Lugari MP Cyrus Jirongo, who succumbed to injuries sustained in a fatal road traffic accident along the Nakuru-Nairobi Highway.
In a statement issued Monday, the DCI confirmed that the crash occurred in the early hours of December 13, 2025, at Karai area, Naivasha, involving Jirongo’s vehicle and a public service vehicle (PSV) bus operated by Climax Company Ltd.
According to preliminary findings, the accident happened at approximately 2:19am and involved motor vehicle registration number KCZ 305U, which Jirongo was driving, and a PSV bus registration number KCU 576A.
The collision was described as head-on, with the impact forcing the deceased’s vehicle about 25 metres from the point of collision, while the bus came to rest roughly 50 metres away.
Following the incident, the DCI deployed a multi-agency team comprising homicide detectives and forensic experts from the National Forensic Laboratory.
“In line with its mandate, the DCI deployed a combined team of homicide detectives and forensic experts from the National Forensic Laboratory, who visited the scene, conducted preliminary examinations, and secured key exhibits,” the statement signed by J.Kmarete on behalf of DCI boss reads.
A key breakthrough in the probe has been the recovery and review of CCTV footage obtained from Eagol Petrol Station, located near the scene of the accident.
Investigators say the footage provides a minute-by-minute account of Jirongo’s final movements moments before the fatal collision.
The CCTV footage shows that at 2:18:40am, Jirongo drove into the petrol station from the Nairobi direction but did not refuel. At 2:19:10am, his vehicle stopped briefly at the station’s exit before, at 2:19:19am, making a right turn back towards the Nairobi direction. Just six seconds later, at 2:19:25am, the footage captured the PSV bus ramming into his vehicle.
Detectives have since interrogated the driver of the PSV bus, identified as Tyrus Kamau Githinji, who had earlier recorded a statement at the Naivasha Traffic Base.
The driver has been released on cash bail pending further investigations into the offence of causing death by dangerous driving.
“He is required to report to the Naivasha Traffic Base on 22nd December 2025 for further police action,” Marete said.
In addition, statements have been recorded from the petrol station’s night guard and fuel attendant, both of whom were on duty at the time of the accident and provided firsthand accounts of the events leading up to the crash.
The DCI said investigations remain ongoing, with the forensic team scheduled to revisit the scene for further analysis.
Detectives are also retracing Jirongo’s movements prior to the accident, including recording statements from individuals he interacted with earlier that night.
Among those being questioned are persons who were present during a meeting at Karen Oasis Bar and Restaurant in Nairobi.
Further analysis of the CCTV footage is underway, while additional statements will be recorded from passengers who were aboard the Climax Company Ltd bus and other potential witnesses along the highway.
Once investigations are concluded, the DCI said a comprehensive police file will be compiled and forwarded to the Director of Public Prosecutions (DPP) for perusal and legal guidance.
The Directorate also conveyed its condolences to the family, friends and relatives of Jirongo while assuring the public that the investigation will be conducted thoroughly, impartially and in strict accordance with the constitution and the rule of law.
