According to Kenya's Standard Media, the late queen died after ingesting 40 capsules of Amitriptyline reportedly used to battle mental illnesses.
Her death occurred within a week of losing sister, Nombuso, whose funeral service she could not attend based on an order given by her husband.
An intense state of depression is believed to have motivated a suicide. The Citizen News submitted that the deceased suffered from a "major depressive disorder and lack of attention disorder."
