Detectives have arrested 17-year-old Lizz Njeri Mwangi in connection with the horrific death of a three-year-old kid in Mchanganyiko, Kiamaina ward, Nakuru county, Kenya.
Along with her mother and other family members, the youngster attended church on Sunday, June 22, 2025.
While the church ceremony was going on, little Margaret Wanjiru would go outside to play, and her mother would return a short while later to check on her.
“When I went outside, I asked her brother where the child was, but she was nowhere to be seen,” Regina, her mother, told reporters.
“While looking for her in the church compound, the mother was informed that her daughter had been spotted outside the church premises, lying on the ground.
“I went and found her lying on the ground, and she was unconscious. We rushed her to the hospital, and she was pronounced d3ad upon arrival.
Investigations started right away, with the authorities retracing the young girl’s final moments by looking through the CCTV footage from the nearby residences. The last person to be spotted with the young Wanjiru as they left the church premises together was Mwangi.
The young girl was taken to a remote location in the neighbourhood by Mwangi, who then strangled her to death.
“She was captured by the secret cameras installed in the area’s street lights committing the cold-blooded murder. The CCTV shows that the girl used the same scarf that I had dressed Wanjiru with,” she said.
When questioned by the authorities on why she did it, she gave bizarre answers that shocked the victim’s family.
“When asked why she did it, she said that she hated my daughter since joining our church,” the victim’s mother added.
Wanjiru’s father said that the girl also attributed her crime to a ‘spirit’ that she alleged possessed her.
“She had said that she had been possessed by a spirit which directed her to do the crime,” he said.
The Directorate of Criminal Investigations (DCI) in a statement on Monday, confirmed that detectives arrested the suspect at her residence in Judea Village, Menengai Sub-Location, within Kiamaina Ward.
Upon arrest, officers recovered the clothes the suspect wore during the commission of the offense as captured on CCTV, as well as the piece of cloth used to commit the heinous act.
