Six people have been convicted in connection with the 2015 murder of former Kabete Member of Parliament George Muchai, the Director of Public Prosecutions has announced.

The six — Erick Munyera, Raphael Kimani, Mustafa Kimani, Stephen Asitiva, Jane Wanjiru and Margaret Njeri — were found guilty of several offences, including robbery with violence and unlawful possession of a firearm and ammunition.

The convictions relate to crimes linked to the killing of Muchai, his two bodyguards and driver in February 2015. The court found Munyera, Raphael Kimani, Mustafa Kimani and Asitiva guilty on three counts of robbery with violence. 

The prosecution established that on the nights of February 6 and 7, 2015, the four violently robbed Michael Ngatia, Gladys Waithera and Irene Muthoni in separate incidents while threatening to use violence.

During the robberies, the group stole property worth about Sh1.1 million, including two motor vehicles, a gas cylinder, four mobile phones, a laptop and cash.

Munyera, Njeri and Wanjiru were also convicted on separate counts of possessing a firearm and ammunition without valid certificates.

The convictions followed a lengthy trial in which the prosecution presented evidence from 36 witnesses linking the accused persons to the crimes.

The Office of the Director of Public Prosecutions said the verdict demonstrates the justice system’s commitment to accountability

“This conviction underscores our commitment to ensuring that perpetrators of violent crime are brought to justice. The Office of the Director of Public Prosecutions will continue to pursue cases diligently to uphold the rule of law and secure justice for victims and their families.”

Sentencing is scheduled for March 18, 2026.

Last year, Director of Public Prosecutions secured a breakthrough in the long-running case of the brutal murder of Muchai, with the High Court in Nairobi ruling that four accused persons have a case to answer.

In a ruling delivered by Justice Kanyi Kimondo, the court affirmed that the DPP had established a strong prima facie sight case against Eric Mungera Isabwa, Raphael Kimani Gachii, Mustafa Kimani Anyoni, and Stephen Astiva Lipopo.

The four are accused of orchestrating the cold-blooded killing of Muchai, his two police bodyguards namely Constable Samuel Kimathi and Constable Samuel Lekakeny alongside his driver, Stephen Ituu Wambugu, along Kenyatta Avenue in February 2015.

This development follows an intensive prosecution, which successfully called 37 witnesses, presenting a blend of direct, circumstantial, and documentary evidence to link the accused to the heinous crime.

Among the testimonies was that of a protected taxi driver who placed one of the accused, Mustafa Kimani Anyoni, at the centre of the crime and produced a gun safety pin discovered in his vehicle, later confirmed as evidence.

In detailed submissions filed by Principal Prosecution Counsel Peris Maina, the DPP demonstrated that the killings were not random but premeditated, pointing to the accused persons’ use of dangerous weapons and the execution-style shootings as evidence of careful planning.

Autopsy reports by government pathologist Johansen Oduor confirmed all four victims died of close-range gunshot wounds from high-velocity firearms.
