A woman poisoned her four children before committing suicide in Rongai, Nakuru county, on Thursday.
The body of the 28-year-old was found floating in a nearby dam.
Three children aged eleven, seven and three months survived as they were rushed to a nearby dispensary and then to a hospital.
One aged two died before she was taken for treatment.
A neighbour said he
immediately alerted others after finding the children unconscious.
The woman's mother-in-law said she added rodenticide to juice and then served her children, alongside a loaf of bread.
"She attempted to strange the three children after realising the other one had died. She fled following the incident at about 2 am after her husband emerged from a different room."
The mother-in-law said the woman had been having an affair with a local herdsmen and that this had angered her husband.
She said the couple had been sleeping in separate rooms.
“She was known in the village
as a troublesome woman. She has been having frequent quarrels with her husband. It's unfortunate that she extended her frustration to her innocent children."
Another neighbour said:
“It is very unfortunate that the woman killed children who were oblivious to her issues."
The survivors were discharged while the bodies were taken to Nakuru county mortuary.
Residents said depression may have contributed to the ordeal.
Rongai police boss Japheth Kioko said investigations were launched.
