A post-mortem report has indicated that Dr Job Obwaka died from cardiac arrest, a finding released on Tuesday, May 5 through a family spokesperson following an examination at the Funeral Home, where the 73-year-old was taken after his sudden death.
The confirmation comes against a backdrop of ongoing investigative interest surrounding the circumstances of his final moments, with the Directorate of Criminal Investigations (DCI) linking the case to possible poisoning linked to an incident said to have occurred at a lady’s residence, where she has since been detained as a person of interest.
Investigators have maintained that the lady was the last person seen with the 83-year-old medic before he collapsed, a sequence that informed her immediate arrest as inquiries into the events leading to his death continued.
Court proceedings had earlier reflected requests for additional time to complete inquiries, with a prosecutor noting the need for further examination of materials collected and forwarded for analysis. “There are certain samples that are to be forwarded to the government analyst, and possibly as a result of two tests or examinations, maybe subsequently a mental assessment examination,” the prosecutor said.
An affidavit filed by the investigating officer indicated that samples were retrieved from Wangari’s residence in Milimani Estate for forensic testing linked to the inquiry, while her defence team maintained that prior searches of the premises had not yielded material supporting the poisoning theory, and questioned the need for further collection of food samples.
Dr Obwaka’s death comes within a broader institutional backdrop tied to governance disputes at the Kenya Hospital Association (KHA), which holds a stake in the ownership structure of Nairobi Hospital, where he was a director involved in internal leadership tensions.
In March 2026, just weeks before his death, Dr Obwaka and three other directors were arrested and charged with conflict of interest, failure to file financial statements between 2022 and 2024, and falsification of membership records, with the group maintaining that the actions taken against them were part of efforts to push for a management takeover.
