Former Deputy President Rigathi Gachagua has launched a fresh attack on the Directorate of Criminal Investigations (DCI), accusing the agency of attempting to shield police officers allegedly linked to the killing of Dr Victoria Nthunya Mutiso.
In a strongly worded statement posted on his official Facebook page on Friday, Gachagua claimed he had received information from what he described as “good officers” regarding the identities of police officers allegedly involved in the case.

Addressing the DCI directly ahead of a scheduled press conference, Gachagua alleged that the briefing was intended to divert public attention and instead implicate boda boda riders.
“Bwana DCI, I have seen you have called a press conference to cover up the police killers of Dr Victoria Nthunya Mutiso and then fix some boda boda riders,” Gachagua wrote on his official Facebook page.
The former deputy president further claimed that he was in possession of the names of three officers whom he alleged were responsible for the doctor’s death, saying they would be made public should the DCI fail to disclose them during the briefing.
“I have the names of the three police killers; we shall release the details after your presser if you attempt a cover-up,” a part of the statement posted on his Facebook account stated.
Gachagua specifically called on investigators to identify an inspector attached to Kikuyu Police Station, a police constable from the same station, and another constable based at Karinde Police Post, saying they were central to the investigation.
He further accused senior officials of protecting officers involved in alleged extrajudicial killings and warned that such practices must end.
“Good officers have given me all the details and your days of covering up killings by police officers must come to an end,” he said.
In another explosive claim, Gachagua urged the DCI to allow what he referred to as the “Nairobi Sierra killer squad”, officers he alleged had been transferred out of Nairobi—to attend the press conference and publicly explain their operations.
According to Gachagua, the officers would reveal who allegedly directed their actions and describe what he termed as their victimization following the transfers.
The allegations come amid heightened public scrutiny over the circumstances surrounding the death of Dr Victoria Nthunya Mutiso, with Kenyans demanding transparency and accountability from investigative agencies.
