Police officers in Nairobi have confirmed the arrest of a key suspect linked to the shooting dead of Mary Lilian Waithera, who was an employee of National Hospital Insurance Fund (NHIF).

Confirming the arrest, Nairobi Police Commander Adamson Bungei revealed that the suspect linked to the shooting of 46-year-old Waithera is Julius Kimani Mwangi.

The NHIF staff member collapsed under mysterious circumstances while walking with her counterparts along Kaunda Street in the Nairobi Central Business District (CBD) last week.

He colleagues, who were with her during the shocking ordeal, were unable to rescue her as she was pronounced dead at the scene by medical personnel who arrived in an ambulance.

The cause of her sudden death after collapsing on the street while holding her chest was revealed by an autopsy that showed that she had been shot from an adjacent building.


During the autopsy at a Nairobi hospital, a bullet was found lodged in Waithera’s lungs, with police confirming last week that her shooting on Monday was from an elevated angle.

The postmortem showed that the bullet entered through her collar bone after she was shot while she was heading home from her NHIF Building office in Upper Hill with her colleagues.

Waithera worked at the NHIF registry department for more than 15 years and her family has been forced to start making preparations for her funeral at her rural home in Embu County.
