Bigirimana allegedly used a toxic substance which he fed to his two children identified as Iranzi Kumbuka 10 and Irizabimbuto Caline aged 8.
This incidence happened on Friday night at Ryamutoto village, Nyamugari cell in Mwili sector.
Neighbours revealed that on the fateful night one of the children Kumbuka is said to have walked into a neighbours house and told them that he wanted drinking water. He also told neighbours that his father had fed them with a substance and that Irizambimbuto had already died.
As the neighbours gave Iranzi drinking water, he died in their hands immediately.
Bigirimana is said to have separated with the mother of Iranzi and Irizambimbuto and married another woman identified as Mukeshimana Solange with whom they lived with these children.
However, Mukeshimana and Bigirimana also had misunderstandings and separated.
