Police in Nyandarua have arrested a man suspected of killing his wife and their three-year-old daughter in Kinangop.

The suspect was intercepted on Monday while travelling in a matatu towards Nairobi at Lari, Kiambu County, just hours after the bodies of his wife, Mary Wanjiru Njogu, 27, and their daughter, Peris Wanjiru, were discovered inside their Kinangop home.

Investigators have named him the prime suspect in the September 2 incident and confirmed he will face murder charges. After his arrest, he was taken back to Kinangop for processing ahead of his arraignment in court.

The motive of the murder was not immediately established.

In another shocking incident, a man is reported to have fatally stabbed his wife before threatening to harm their three young children during a domestic dispute in the Obama Estate, Kayole, Nairobi.

According to a police report, the man also threatened to take his own life as his children looked on in horror at their mother’s body lying in a pool of blood.

The incident, which occurred on Tuesday, September 2, 2025, in the Budalangi area, involved 32-year-old Eunice Wanjiku Wambui.

After allegedly killing his wife, the suspect locked himself inside the house with the children, vowing to kill them and die by suicide. Locals, with the help of police, broke through the roof and door to rescue the children. The suspect was also subdued and arrested, Nairobi Regional Police Commander George Seda confirmed.

The woman’s body was recovered from the sitting room, where she had died from the stab wounds. The motive behind the killing remains unclear.

Police say the suspect is expected to face murder charges. The body has been taken to the mortuary pending postmortem and further investigations.
