Police are holding a woman who poisoned her three children aged six months, four years, and three years in Thogotho, Kiambu County.
It is suspected that after killing the three children, the mother attempted to hang herself inside her house.
Neighbors said that this might have then failed, since they heard a loud bang in the house, and on arrival, they found her on the floor.
The bodies of the three children lay lifeless on a bed on Saturday.
The bodies of the three children were taken to Thogoto hospital mortuary as the mother was arrested and taken to Kikuyu police station
Neighbors said the woman would often lock herself and her children in their house and lived a very quiet life.
Kikuyu police boss Ronald Kirui said the motive of the murder has not been established.
Kirui added that preliminary investigations hint at a family conflict in the home.
Police have started investigations into the matter, and a suicide note that the mother had written will be used.
The homicide detectives will also record a statement from the father of the house who was absent during the incident.
