 His death was probably caused by injuries sustained during, and possibly after, his arrest and he was buried on his way to detention, whether already dead or assumed to be dying is unclear.Wambui disputed the charge that Waiyaki collaborated with the British colonists, by preferring Kikuyu oral traditions to historians’ versions that she labelled as Eurocentric, even where the historians are Kenyan, and claimed the family of Waiyaki wa Hinga were the natural leaders of Kenya because of his actions.Wambui's grandfather, Munyua Waiyaki, donated some land he owned to the local Church of Scotland mission, as a result of which his son, Waiyaki Wantoni, often known as “Tiras” was educated at a Church of Scotland school and, in the 1940s, became Kenya's first African police inspector and later a chief inspector,, which Wambui claimed was compensation for the death of Waiyaki wa Hinga.
