She told him that he was not in Nairobi and told him to enter the house and check whether her husband was in the house . He told her that the only way could do that is if he called the chief . He met the chief around 4:00 PM who was PW2. The chief told him that he had been rang by PW5 to check for the husband. They proceeded to the house and they found the accused. The chief asked him the whereabouts of his father and the accused said he did not know. 8. They entered the house and found that the bedroom was locked. The house had more than four rooms including the sitting room. The deceased bedroom had external padlocks which was locked. The chief proposed that he would climb on a ladder to peep into the room as there was no ceiling. they went and looked for a ladder and a son of the PW1’s cousin said he had noticed some flies lingering nearby.

He later witnessed the postmortem on the 27th of June 2020 at Kilungu Hospital and identified the body for postmortem .He noticed that the deceased had an injury at the back of the head. 10.

19. However, he told the court that on 20th June 2020 he found his father in a small house outside the home sated . Beside him there was an axe. He said he took it and struck him on the head and the neck, saying that he had come to the conclusion that his father was pursuing him for murder. He said his father had withdrawn his privileges, electricity bills, pocket money . He said his father was coming at him the wrong way. 20. I have carefully considered the evidence before me and the only issue is whether the prosecution has proved the charge against the accused beyond a reasonable doubt. I must also consider whether the accused person falls within the exemption provided for by s. 12 of the Penal Code. 21. It is the duty of the prosecution to establish each of the ingredients of murder as set out by s. 203 & 206 of the Penal Code. In Republic v Andrew Omwenga [2009] eKLR the court held that “ For the offence of murder to be proved, the prosecution must prove beyond reasonable doubt the following three ingredients: (i) The death of the deceased and the cause of that death, (ii) That the accused committed the unlawful act or omission which caused the death, and (iii) That the accused had malice aforethought.” 22. Death of the deceased and the cause of that death, the perpetrator 23. The accused was the one who was left with his father at home. He had the keys to the room where his father lay dead for three days . he lied severally to his uncle that he did not know where his father was. He later admitted to having struck him with the axe because his father had withdrawn his privileges, stopped giving him money and confiscated his phone. Malice aforethought 24. The accused is said to have suffered mental illness. His mother said he did not know what he was doing but it is clear that the accused was aware of what he did and why. He was angry with his father for withdrawing his privileges , took an axe and struck him. He also concealed the body and lied about his father’s whereabouts. The penal Code provides that every person is presumed to be of sound mind until the contrary is proved . This is at s. 11. At s. 12 it states : A person is not criminally responsible for an act or omission if at the time of doing the act or making the omission he is through any disease affecting his mind incapable of understanding what he is doing, or of knowing that he ought not to do the act or make the omission; but a person may be criminally responsible for an act or omission, although his mind is affected by disease, if such disease does not in fact produce upon his mind one or other of the effects above mentioned in reference to that act or omission. 25. There is evidence that the accused was in 2018 was admitted at Fountain of Hope Treatment Centre for three months . he was diagnosed with schizoaffective mental disorder. He was treated, discharged on treatment and directed to resume his education. He was also treated at Avenue Hospital. The Psychiatrist at Mathari Teaching and referral hospital did not find any record of treatment there and stated as such . 26. Having reviewed the evidence it is my view that although the accused had a disease of the mind the actions and the reason for the action demonstrate that at that time, he knew what he was doing and https://new.kenyalaw.org/akn/ke/judgment/kehc/2025/13456/eng@2025-09-26 3

why. He had the presence of mind to think about what the father was denying him, to kill him and hide his body, to lie about his whereabouts. 27. Seeking to answer the question whether there was malice aforethought the learned Judge in Republic v Eregai [2025] KEHC 731 (KLR) stated Furthermore malice aforethought has been considered in several cases. The Court of Appeal in Odio v Republic [2024] KECA 1544 (KLR) stated that: -“ 20. Malice aforethought may be express or implied. Express malice aforethought refers to when a deliberate intention is manifested to take away the life of a person unlawfully. Implied malice aforethought applies when no considerable provocation appears or when the circumstances attending the killing show a reckless and wicked heart. To be convicted of murder, malice aforethought must be proved. Malice aforethought cannot be imputed to an accused person based solely on their participation in a crime. If it is shown that the killing resulted from an intentional act with express or implied malice aforethought, no other mental state need be shown to establish malice aforethought. In Nzuki v . Republic [1993] eKLR, this Court defined malice aforethought as: …a term of art and is either an express intention to kill, as could be inferred when a person threatens another and proceeds to produce a lethal weapon and uses it on his victim; or implied, where, by a voluntary act, a person intended to cause grievous bodily harm to his victim and the victim died as the result. See the case of Regina v Vickers, [1957] 2 QB 664 at page 670. An intention connotes a state of affairs which the person intending does more than merely contemplate: it connotes a state of affairs which, on the contrary, he decides, so far as in him lies, to bring about, and which, in point of possibility, he has a reasonable prospect of being able to bring about, by his own act of volition. See the case of Conliffe v Goodman, [1950] 2 KB 237.” 39. Furthermore, in the case of; Tubere s/o Ochen {1945} 12 EACA 63 the court (COA?) stated that in considering whether there was malice aforethought, the court will look out for characteristics such as; the nature of the weapons used, the manner it was used to inflict the injuries, the parts of the body targeted whether vulnerable or not, the nature and gravity of the injuries, and the conduct of the accused before, during and after the incident. (See also DafasiMagayi v Uganda {1965} 1 EA 667). (emphasis added) 28. The accused was upset with his father. He picked an axe, struck him on the head and the neck, the impact caused bleeding in the chest. 29. This in my view established the fact of malice aforethought on the part of the accused person. 30. In the circumstances I find that the charge is proved beyond a reasonable doubt. 31. I find the accused person guilty of murder c/s 203 as read with s. 204 of the Penal code and convict him accordingly.
