The plea taking for Kithuka Musyimi, the prime suspect in
the killing of a General Service Unit (GSU) officer attached to State House,
has been deferred after the High Court was informed that his mental assessment
report is not yet ready.
When the matter came up before Justice Diana Kavedza on Thursday,
November 13, 2025, the prosecution told the court that the report, which is
required before the suspect can plead to murder charges, would be ready within
two weeks.
Justice Kavedza emphasised that the report was crucial in
determining whether Musyimi was mentally fit to stand trial.
“We do not have the mental assessment report. Without it, we
will not know whether your client is fit to plead,” the judge said.
“We will therefore give a further mention on November 27 for
the plea.”
The court also appointed lawyer Martin Nabende to represent
the suspect, ensuring that Musyimi has legal counsel during the proceedings.
The judge directed that once the mental report is filed,
both the prosecution and defence will be notified ahead of the next mention
date.
The prosecution, led by a State counsel, confirmed that the
assessment is being conducted and that arrangements have been made to expedite
the process. The suspect remains in custody pending the filing of the report.
Musyimi is the prime suspect in the murder of GSU officer, Ramadhan Khamisi, assigned to guard the State House Gate D along Dennis Pritt Road in Nairobi.
According to investigators, the incident occurred earlier on
October in what authorities described as a rare and violent attack targeting a
security officer within one of the country’s most heavily protected zones.
Court documents indicate that the slain officer, who was manning the gate on the day of the incident, was reportedly attacked by a man armed with two traditional arrows.
"The respondent, who was armed with a bow and arrows that he had concealed in a blue sack, posing as a street dweller, advanced towards the GSU officer manning the search barrier, one Ramadhan Khamisi," court documents state.
“He threw two arrows; the second one got to the officer Ramadhan, after which they were able to apprehend the suspect,” Boya testified.
The officer sustained severe injuries and was rushed to Kenyatta
National Hospital (KNH), where he succumbed while undergoing treatment.
The investigating officer, Inspector Bashir Boya, told the
court that police recovered the weapons believed to have been used in the
assault.
He added that the suspect was subdued and arrested shortly
after the attack and has since been held in custody as investigations continue.
