A court in Naivasha on Monday ordered seven more days in police custody for a woman accused of killing her four children.
Investigators, in a miscellaneous application, had asked the court for more time to finish the investigation.
The accused did not take a plea and will be held at a police station ahead of a mental health assessment.
Post mortems will also be carried out within the seven days.
The woman was produced in court as police are required to do so within 24 hours of holding a suspect.
In a written confession with details of what happened that fateful day, the woman claimed she was possessed by evil spirits.
She has made this claim since she was arrested on Saturday after police raided her hideout in Kayole on the outskirts of Naivasha town.
She went into hiding despite stating in the letter that she would surrender at a police station.
The woman also said she decided to kill her children for lack of a job, hence an inability to provide for them, but people who visited her house said she had enough food.
On Sunday evening, officers at the Directorate of Criminal Investigations questioned her for more than three hours.
Her brother whom he spoke to before her arrest was among those who recorded statements with the police.
The woman’s brother, whom she spoke with before her arrest, is among those who have recorded statements with police.
A taxi driver she mentioned in the letter and her landlord were also questioned on Sunday.
The case will be heard on July 6.
