Gachagua Was in Contact With Main Suspect in Dr Victoria Mutiso Murder, DCI Says

NAIROBI, Kenya – The Directorate of Criminal Investigations (DCI) has alleged that former Deputy President Rigathi Gachagua was in communication with individuals linked to the murder of mental health doctor Dr Victoria Mutiso, including one of the key suspects in the case.

The allegation was made on Friday, August 7, by DCI Director Mohamed Amin, as detectives provided an update on investigations into the fatal shooting that occurred in Nairobi’s Upper Hill area.

Amin said investigators had examined communication records and established what he described as contact between Gachagua and one of the main suspects believed to have information about 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 Director further alleged that investigators had established communication between Gachagua and the motorcycle rider accused of transporting one of the suspected attackers.

“We were able to establish that apparently he also appears to have been in communication with the boda boda rider,” Amin disclosed.

Amin said investigators were not treating the matter as a political dispute but as part of efforts to establish how information about the murder investigation reached different individuals.

“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 said.

Gachagua Denies Contact With Suspects

Gachagua later rejected the allegations, insisting that he had no communication with anyone involved in the murder.

Speaking during the opening of the Democracy for Citizens Party (DCP) offices in Kiambu, the former Deputy President questioned how he could have interacted with suspects while staying at his Wamunyoro residence.

“Where do I get to interact with the murder suspects while I was at my home in Wamunyoro?” Gachagua asked.

He maintained that the information he has previously shared about security matters came from individuals within government security agencies rather than people involved in criminal activities.

The competing claims have added a new dimension to the investigation, with the DCI maintaining that its findings are based on intelligence and forensic evidence while Gachagua continues to deny any connection to the suspects.

DCI Details Investigation Into Mutiso’s Killing

Amin said detectives had made significant progress in the investigation, identifying several people who allegedly played different roles in planning and executing the attack.

The DCI has identified an alleged organiser of the murder plot, the motorcycle rider suspected of transporting the gunman and other individuals believed to have been involved in the operation.

Investigators have also alleged that serving police officers played roles in the conspiracy.

A police constable attached to Karinde Police Post under Kikuyu Police Station has already been arrested. Detectives allege that the officer was the gunman who fired the fatal shots.

The DCI has also linked a police inspector attached to Nderi Police Post to the investigation, alleging that the officer helped connect the suspected financiers with the operational team and provided the firearm allegedly used in the killing.

Mutiso Had Survived Earlier Attack

Amin also revealed that Dr Mutiso had survived an earlier attempted attack on July 7, 2026.

According to the DCI, two men riding a motorcycle allegedly pointed a firearm at her along Ngong Road near Junction Mall, but she managed to escape unharmed.

Detectives are now examining whether the earlier incident was connected to the eventual killing.

The DCI is also investigating whether individuals linked to Mutiso’s murder could have connections to another high-profile shooting reported in 2025.

Doctor Shot Dead in Upper Hill

Dr Mutiso was fatally shot on the morning of Wednesday, July 29, at approximately 9am near the junction of Mbagathi Link Road and Mawenzi Road in Nairobi’s Upper Hill.

The killing has generated significant public interest, with questions raised over the motive, the alleged involvement of serving police officers and the identity of those who may have financed or coordinated the attack.

The DCI said investigations remain ongoing, with detectives pursuing additional suspects and examining communication, forensic and intelligence evidence as they work to establish the full circumstances surrounding Dr Mutiso’s death.
