Dr. Victoria Mutiso killing: Mother, son arraigned as police probe links to lawyer Kyalo Mbobu murder

Two suspects, a mother and son, linked to the murder of clinical psychologist and researcher Dr. Victoria Nthunya Mutiso, were on Friday arraigned at the Milimani Law Courts as the prosecution sought to detain them for 30 days to allow detectives to complete investigations.

The latest developments come as investigators explore a possible link between Dr Mutiso's killing and the fatal shooting of lawyer Mathew Kyalo Mbobu last year.

The two suspects, Rose Mbithe Mulwa and her son Chris Mulwa, appeared before the Milimani Law Courts after they were arrested on Thursday in Karen during what detectives described as an intelligence-led operation.

The prosecution asked the court to allow investigators to detain the pair for 30 days as investigations into the murder of Dr. Mutiso continue.

In an application supported by an affidavit sworn by Corporal Romana Odour, investigators told the court that Dr. Mutiso had reported two separate incidents in which unknown men riding a motorcycle allegedly trailed and threatened her before she was fatally shot.

According to the affidavit, on July 7, 2026, Dr. Mutiso was driving along Ngong Road near Junction Mall when two men on a motorcycle allegedly pointed a gun at her and attempted to shoot her. She escaped unharmed and later reported the incident at Kilimani Police Station.

Police further state that after the incident, Dr. Mutiso informed investigators and her husband that she had identified the pillion passenger on the motorcycle as Chris Mulwa.

The prosecution says Rose Mbithe Mulwa is the former wife of Dr. Mutiso's husband, Prof. David Musyimi Ndetei. The two reportedly divorced in 2001 after having four children together, including Chris Mulwa.

As investigations entered their third day, detectives widened the probe to determine whether Dr. Mutiso's killing is linked to the murder of lawyer Mathew Kyalo Mbobu, who was shot dead in September 2025.

The new line of inquiry follows revelations that Mbobu represented Prof. Ndetei in a property dispute involving his former wife, Rose Mbithe Mulwa.

The case, filed in 2002, centred on the ownership and division of matrimonial assets, including land and property worth billions of shillings.

Investigators are also examining similarities between the two killings.

Mbobu was reportedly trailed before he was gunned down along Magadi Road on September 9, 2025.

Nearly 11 months later, Dr. Mutiso was similarly followed by assailants on a motorcycle before she was shot while travelling in a taxi in Nairobi's Upper Hill on her way to work.

Her killing came 24 days after she reported receiving threats to her life at Kilimani Police Station.

"On the 7th day of July at around 18:30 hours, I was driving from Upper Hill towards home behind Junction Mall...while at Dagoretti Corner junction I stopped at the traffic lights immediately one rider came to the window and showed me a pistol. I drove off through the traffic lights to the opposite direction to Kilimani Police Station to make a report,” read the affidavit.

As detectives intensify the hunt for those behind the killing, an autopsy conducted on Dr. Mutiso's body revealed that she was shot three times.

Oduor said another bullet hit the upper body, leading to her death following grave injuries sustained.

“We found that she was shot three times: twice on the head, the two gunshots which exited on the right side; the entry was on the left side and the exit on the right side. There was also another entry on the back,” she said.

“What led to her death was severe bleeding and chest injury and also head injury because of the three bullet wounds.”

The exercise was supervised by the Head of Homicide from the DCI headquarters, Martin Nyoguto and family members who braved the long, chilly day to receive the reports.
