Dr. Clement Munyao Katiku once spent his days navigating the intricate, delicate folds of the human brain, wielding a scalpel to save lives at Kenyatta National Hospital. Today, his world is measured in the cold, concrete dimensions of a cell at Kamiti Maximum Security Prison, where he is serving a 25-year sentence for a murder he steadfastly maintains he did not commit.

For more than a decade, the former neurosurgeon has remained at the center of a haunting legal narrative—a case that transformed a respected medical specialist into a convict. His conviction, which dates back to the 2009 murder of Moses Gituma, a senior official at the Central Bank of Kenya and brother to former Police Commissioner Mathew Iteere, continues to raise uncomfortable questions about the nature of circumstantial evidence within the Kenyan judicial system. As of March 2026, Dr. Katiku remains incarcerated, still fighting to clear a name that was once synonymous with surgical excellence.

The Chain of Custody and a Fatal Mistake

The sequence of events that dismantled Dr. Katiku’s life began with a seemingly mundane, everyday transaction in 2005. According to testimonies provided during his trial, Katiku purchased a second-hand mobile phone from a mortuary attendant at Kenyatta National Hospital. He reportedly bought the device for KES 2,000 to gift to his daughter, then a student at Moi University, ensuring she could stay in contact with the family. The transaction, routine for thousands of Kenyans navigating the informal economy, would eventually become the fulcrum upon which his freedom was pried away.

Years later, the phone was identified by police as belonging to the late Moses Gituma, who had been brutally robbed and killed in the Garden Estate area of Nairobi in 2009. Investigators traced the device from the victim to the informal market, then to the mortuary attendant, and eventually to the doctor’s daughter. When detectives pursued the digital trail, they arrived at the doorstep of the surgeon. Katiku maintains that he cooperated fully, explaining the origin of the phone, but the court’s decision hinged on the possession of the device as a critical link to the crime scene.

• 2005: Dr. Katiku purchases the second-hand mobile phone for KES 2,000.
• 2009: Moses Gituma is murdered police trace the stolen phone to Dr. Katiku.
• 2010: Dr. Katiku and co-accused Anthony Muthie Mati are convicted in High Court Criminal Case No. 15 of 2010.
• Post-2010: Appeals, death row, and eventual commutation to a 25-year sentence.

A Medical Career Disintegrated

Dr. Katiku’s background remains a point of deep contention among those who follow his case. He graduated from the University of Nairobi in 1980 with a Bachelor of Medicine and Surgery, later earning a Master’s in Human Medicine and Pathology, and adding a Master’s in Forensic Medicine from Scotland in 1991. Before his arrest, he was a fixture at Kenyatta National Hospital, performing complex neurosurgical procedures. His sudden removal from the medical register and subsequent incarceration left a void in his family and his professional community.

In interviews conducted from behind prison walls, the former surgeon has expressed a profound sense of abandonment. He notes that the very institution where he saved lives—Kenyatta National Hospital—effectively distanced itself from him the moment the charges were filed. For the medical community in Nairobi, his case serves as a cautionary tale about the intersection of high-profile crime investigations and the reliance on circumstantial evidence, where a simple purchase can derail an entire lifetime of service.

Life Behind Bars: The Surgeon-Turned-Paralegal

Despite the constraints of prison life, Dr. Katiku has not remained idle. He has channeled his analytical mind into the study of law, becoming a prison paralegal to assist fellow inmates with health and legal advice. He describes his current role as a continuation of his life’s work—healing, albeit in a drastically different capacity. He provides guidance to those who, like him, find themselves enmeshed in a legal system that often moves too slowly and relies on evidence that may not always tell the full story.

However, the personal cost remains immeasurable. He reflects on lost years, missed family milestones, and the permanent stain on a record that was once exemplary. Critics of the judicial process in Kenya often point to cases like Katiku’s to highlight the systemic gaps in forensic investigation, particularly when high-ranking officials—like the brother of a former Police Commissioner—are the victims. The pressure to secure a conviction in such high-profile cases can sometimes lead to a focus on convenient suspects rather than the deeper, more complex web of true criminality.

The Question of Justice in Kenya

The case of Dr. Katiku is not an isolated one in the annals of Kenyan criminal history. It mirrors broader debates about the reliability of mobile phone tracking as the primary anchor for murder convictions without additional, corroborating forensic evidence. While the prosecution successfully convinced the court that the chain of custody for the phone implicated the surgeon in the wider conspiracy of the robbery and murder, his defenders argue that the absence of direct evidence—such as DNA, fingerprints, or witnesses placing him at the scene—renders the conviction a miscarriage of justice.

As the legal landscape in Kenya continues to evolve, with increasing focus on case reviews and the integrity of evidence handling, stories like that of Dr. Katiku provoke a necessary, if uncomfortable, public conversation. Does the possession of stolen property automatically equate to the commission of murder? And in a country where second-hand markets are the lifeblood of the informal economy, how many other innocent citizens are one bad purchase away from a life sentence?

For Dr. Katiku, the cells of Kamiti represent a reality he still struggles to accept. His persistence in maintaining his innocence, even after more than a decade of incarceration, suggests a man who believes that the truth, no matter how obscured by legal precedent, remains the only currency that matters. Whether his path leads to an exoneration or a quiet completion of his 25-year term, his story serves as a lingering reminder that the cost of justice is often paid by those the system has already decided are guilty.
