A person of interest linked with the death of veteran gynaecologist and Nairobi Hospital director Dr Job Obwaka, Beatrice Wangari, has been arraigned at Kibera Law Courts.

Wangari was arrested on Friday, May 1, 2026, at around 9;00 pm, while at the Nairobi Hospital after it emerged that she was the last person with the 79-year-old deceased gynaecologist.

Dr Obwaka was pronounced dead on arrival at the hospital after suddenly falling ill while in Kitengela on Labour Day, May 1, 2026.

The Directorate of Criminal Investigations (DCI) are seeking to detain Wangari for 14 days at the Kilimani Police Station or any other police station to enable them to complete investigations.

According to the court papers, they are investigating a possible case of suspected poisoning, which could have occurred at Wangari’s residence.

According to Sergeant Rhoda Nzioka, they established that when the deceased requested to rest at Wangari’s master bedroom after they had shared a meal.

The court papers reveal that she later joined the deceased, and they got intimate, where the deceased developed complications.

“The respondent (Wangari) prepared a meal, which the deceased (Dr Obwaka) took, after which he requested to rest in the master bedroom before being joined by the respondent (Wangari), and they became intimate,” part of the miscellaneous application reads.

Wangari then sought help from her neighbour Shadrack Korir, who accompanied her to her house and found the deceased lying supine on the bed, unresponsive, dressed in a white vest and black trousers with his eyes closed.
