Police are questioning a brother of Mukurwe-ini MP Kabando wa Kabando in connection with the death of his mother on Sunday.
Ms Rose Wachera Mwangi, 70, was hacked to death at around 2pm at Kaini Village in Mukurwe-ini.
Witnesses said Ms Mwangi was at home with her son Caesar Thiari, 40, who is in police custody.
A relative, Ms Agnes Njeri Macharia, said she was returning home from church with friends when they heard screams from the compound.
Brandishing a panga
“I shouted at my cousin (Thiari) who was in the compound but he did not respond. The gate was locked from inside and we started screaming,” Ms Macharia recalled.
The high perimeter wall, she added, prevented them from forcing their way into the compound.
Ms Macharia said her cousin emerged from the gate brandishing a panga and chased them away.
“We had to run for our lives and seek refuge in a neighbour’s home as he was armed with a panga,” she said.
She said they heard the suspect shouting; “Mambo imekwisha, Mambo imekwisha!” (It is over. It is over) and once he ran away, they rushed into the compound only to find her aunt’s body.
Ms Macharia said the MP’s mother had missed the day’s church service and had been left home together with her son.
Area Nyumba Kumi team leader Maina Karanja claimed the suspect was mentally ill.
Mukurwe-ini Deputy County Commissioner Isaac Masinde said they had informed close relatives including the MP and were waiting for them to arrive.
He said they received reports of the killing at around 2pm from Mr Kabando’s personal assistant.
Residents arrested the suspect and handed him over to the police.
Shocked villagers thronged the home of the MP to offer their condolences.
