Lawrence Warunge, the prime suspect in the murder of five Kiambu residents including his father, mother, brother, nephew and a worker, has been found unfit to stand trial.
Mental results presented by a psychiatrist before a Kiambu court established that Warunge was not fit to stand trial.
The court ordered Warunge to be remanded for a further 30 days after which a second mental assessment would be undertaken.
Chief magistrate Patricia Gichohi ordered Warunge to be held in police custody in Nairobi until March 1, 2021 when the matter will be mentioned.
The suspect's girlfriend was released after she reached a deal to become a state witness against the university student.
Kenyan law requires that every person has a right to legal capacity which entails being in the right state of mind to understand the charges.
Warunge and Muthoni failed to take a plea in court on Monday, January 25, as had been anticipated to allow for a mental examination to be conducted.
The 22-year-old University student confessed to killing his four family members and a farmhand.
Postmortem results confirmed that all the victims revealed that they had succumbed to multiple stab wounds likely inflicted by the same person.
Chief Government Pathologist Johansen Oduor stated that the five had similar injuries, stab wounds to the chest and blunt force trauma to the head.
Great vessels of the neck were injured thus leading to massive blood loss and eventual death.
