An three-month-old was deliberately left orphaned by a gang that raided a home in Kericho.
The couple was found brutally murdered in Melit village near Kericho, while their son was left untouched.
The murder victims, who were said to have been repeatedly stabbed, were discovered by a neighbour who went to the homestead in the evening.
Kipchebor MCA Erick Bett condemned the incident, saying security agencies must bring to book the murderers as a matter of urgency and rid the area of crime.
“This is a diabolical act that must be condemned by all in the society. Killing a mother, her husband and a child is the most heinous crime to have been witnessed in the region in the recent past,” said Mr Bett.
Residents in the area have similarly called upon authorities to beef up their security as such cases have been on the rise.
