Detectives confirmed that a hit squad comprising serving police officers was promised a payout of Ksh 1.5 million to execute the doctor near Raila Odinga Highway on July 29.
The Masterminds and the Multi-Billion Property Dispute
According to DCI homicide detectives, the contract killing was orchestrated and funded by Rose Mbithe Mulwa (the former wife of Dr. Mutiso’s husband, Prof. David Musyimi Ndetei) and her son, Christopher (Chris) Mulwa.

The murder stems from a long-standing, multi-billion-shilling family property dispute and land conflict. Detectives are also examining possible links between Dr. Mutiso’s killing and the September 2025 murder of lawyer Matthew Kyalo Mbobu, who had previously represented Prof. Ndetei in land litigation involving Rose Mbithe.
