High Court judge Christine Meoli said that the class three student from Kibuyu village in Magumu had a case to answer over the murder of 11-year-old Mary Nduta Wairimu.
The judge said that she would deliver her ruling on the 31st of May 2017 after a report by the Kinangop probation officer.
She further directed that the minor who is represented by lawyer Francis I. Mburu be detained at Engineer police station awaiting the ruling.
The minor had been charged that on the 5th of July 2016 while armed with a sharp knife he stabbed the 11-year-old girl to death.
In the court documents, the minor says that some forces directed him to stab the minor whom according to him was his girlfriend.
In a statement to the police, the class three student said that while having intercourse with the deceased a tall man with a panga and a shiny knife appeared and issued him with the orders.
He said that the stranger directed him to stab the girl several times before he went to the deceased sister and informed her what he had done.
Meanwhile, a fifty five year old man has been jailed for life by a Naivasha court after he was found guilty of defiling his 13-year-old daughter one year ago.
The former hotelier turned farmer was left in tears following the ruling by the deputy registrar at the Naivasha High Court Zainabu Abdul.
The accused Peter Matheri Macharia had been charged that on the 12th of June 2016 at Maella Village he sexually abused his daughter.
The accused who was unrepresented faced an alternative charge of indecently assault the minor by touching her private parts.
In her testimony, the minor told the court how her father turned against her as the mother was away in hospital attending to a sick relative.
The class eight student said that the father grabbed her by the mouth to avoid her from screaming before committing the act.
In her ruling, the magistrate termed the offence as serious adding that the father who was supposed to be the protector of the minor had turned out to be a predator.
Zainabu dismissed the accused defense that he had been framed adding that medical report adduced in the court had proven that the minor was defiled.
