The recent murders of prominent Nairobi lawyer Mathew Kyalo Mbobu on September 9, 2025, and clinical psychologist Dr Victoria Mutiso on July 29, 2026, appear connected through a complex web of personal conflict. Investigations suggest that a bitter divorce and ensuing property dispute are at the core of these tragic events.

Central to the case is Rose Mbithe Ndetei, also known as Rose Mbithe Mulwa, the former wife of Professor David Musyimi Ndetei. The couple's divorce in 2001 was followed by a protracted legal battle over matrimonial property, which sources indicate may have escalated tensions leading to the two killings.

  • Dr Victoria Mutiso, a clinical psychologist, was murdered in July 2026, with evidence pointing toward a connection with the earlier killing.
  • Authorities are examining the nexus between the murders, focusing on the unresolved disputes stemming from the divorce and defamation issues involving Rose Mbithe Ndetei.
