The Directorate of Criminal Investigations (DCI) has claimed that former Deputy President Rigathi Gachagua was in communication with individuals linked to the murder of mental health doctor Victoria Mutiso, including one of the key suspects in the case.
Speaking during a press briefing on Friday, August 7, DCI Director Mohamed Amin said investigators had established communication between Gachagua and one of the people they believe played a role in the murder.
"Unfortunately, what clearly came out of this is that Honourable Rigathi Gachagua was in communication with one of the main suspects who was feeding him with this information," Amin said.
The DCI boss further claimed that detectives had also found evidence indicating that Gachagua had been in contact with the motorcycle rider who allegedly transported the suspects involved in the killing.
"We were able to establish that apparently he also appears to have been in communication with the boda boda rider," Amin said.
Amin questioned why Gachagua did not share the information directly with investigators if his intention was to assist in the probe.
"If really Rigathi Gachagua meant well for these investigations, because we are not trying to deal with politics, then he should have shared the information with investigators," he added.
However, Gachagua rejected the claims, saying he was not in contact with any murder suspects and questioning how he would have interacted with individuals accused of the crime while at his home in Wamunyoro.
"Where do I get to interact with the murder suspects while I was at my home in Wamunyoro?" Gachagua asked.
The former Deputy President maintained that the information he shared came from within security circles and not from people involved in the murder.
The allegations emerged as the DCI provided an update on investigations into the fatal shooting of Dr Victoria Mutiso, saying detectives had made progress through forensic analysis and intelligence-led operations.
According to Amin, investigators have identified individuals suspected to have organised the murder plot, including the person believed to have coordinated the operation, the motorcycle rider who allegedly carried the gunman, and other people suspected of playing various roles.
The DCI also alleged that rogue police officers may have been involved in the crime, claiming some officers helped coordinate the operation while another allegedly provided the firearm used in the shooting.
One of the officers identified by investigators is a police constable attached to Karinde Police Post under Kikuyu Police Station, who has since been arrested over allegations that he fired the fatal shots.
Amin further revealed that Dr Mutiso had survived an earlier attempted attack on July 7, when two men on a motorcycle allegedly confronted her along Ngong Road near Junction Mall before she escaped unharmed.
The DCI said investigations are still ongoing, with detectives pursuing more leads and examining whether some suspects connected to the murder may also have links to another high-profile shooting reported in 2025.
Dr Mutiso was killed on the morning of Wednesday, July 29, at around 9am at the junction of Mbagathi Link Road and Mawenzi Road in Nairobi's Upper Hill area.
