Mysterious Death Shakes Nation: Police Investigate Dr. Obwaka's Suspected Poisoning
Authorities are seeking a 14-day detention for Beatrice Wangari, the prime suspect in the mysterious death of prominent physician Dr Job Obwaka. Investigators suspect poisoning, revealing that Wangari and Obwaka, who were long-term lovers, shared a meal and were intimate hours before his sudden demise at her Kitengela residence. The complex murder probe continues with forensic analysis pending.
The Directorate of Criminal Investigations (DCI) told a Nairobi court that preliminary findings point to a potential poisoning incident that may have occurred at the residence of Beatrice Wangari in Kitengela.
Wangari, 45, who is being treated as a person of interest, was arraigned at the Kibera Law Courts after spending the weekend in police custody.
She is believed to be the last person seen with the 83-year-old medic before he collapsed.
The Prosecution asked the court to grant investigators 14 days to complete inquiries, including a postmortem and toxicological 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.
In an affidavit, investigating officer said samples collected from Wangari’s residence in Milimani Estate would be subjected to forensic testing to establish whether poisoning occurred.
According to police, Dr. Obwaka collapsed on May 1 while at Wangari’s residence in Kitengela, where he had gone on personal errands.
After sharing a meal, he reportedly became unwell and was later found lying unresponsive with a weak pulse and laboured breathing.
Wangari is said to have called a neighbour for help, prompting an ambulance response. Paramedics attempted cardiopulmonary resuscitation as he was rushed to Nairobi Hospital, where he was pronounced dead on arrival.
The incident was subsequently reported at Kilimani Police Station at 10:00 pm the same night, under OB 63/01/05/2026.
Following the report, investigators executed a search at Wangari’s residence, recovering several items central to the murder probe.
These included two plates, one spoon, a water glass, assorted drugs, a blanket, a bedcover, a wet shawl, a 750ml bottle of half-consumed Robertson Winery, and a 187ml bottle of Stone Dale.
All these items were found unwashed with food stains in the kitchen sink and are now awaiting escort to the Government Chemist for comprehensive toxicological analysis to establish the exact cause of death.
Sgt Nzioka highlighted the complexity of the case, given the relationship between the suspect and the deceased.
The court was also informed that Wangari, a single mother of two, is yet to undergo a mental assessment.
The prosecutor argued that while Wangari has a right to bail, the circumstances surrounding the matter place her life in potential danger, supporting the state’s request for continued custodial orders.
