Ellius Onyango Rieba v Republic
The bottom line
#Kenya's Court of Appeal upheld a life sentence for murder, confirming that circumstantial evidence and the 'last seen' doctrine can prove guilt without eyewitnesses.
What this practically means
#Executive summary
#Key legal issues
#Circumstantial evidence threshold
The circumstantial evidence - PW4's testimony placing the appellant with the deceased, prior domestic quarrels, and the appellant's disappearance - formed a complete chain excluding any other reasonable hypothesis, meeting the Abanga/Koske threshold.
The court restated the three-part test from R v Kipkering Arap Koske and Abanga alias Onyango. It found PW4's evidence placed the appellant at home with the deceased that morning, contradicting his alibi. Two weeks of domestic tension provided motive. His disappearance after the burial, and arrest 20 months later, suggested consciousness of guilt. The chain left no other conclusion.
Doctrine of last seen
The appellant, being the last person seen with the deceased and failing to offer a satisfactory explanation for her death, could properly be presumed responsible for it.
Relying on Chiragu & Another v Republic as approved in Stephen Haruna, the court held the appellant was last seen with the deceased, who was found dead hours later in the same house. The burden shifted to him to explain the death; his failure justified the inference that he killed her. The alibi was contradicted by PW4's testimony placing him home at 6:30 am.
Elements of murder and malice aforethought
Death and its cause were proved by the post-mortem showing asphyxia from vertebral dislocation; strangulation with neckties breaking neck bones demonstrated an intention to cause death, satisfying malice aforethought under Section 206 of the Penal Code.
The court tested the evidence against the elements of murder: fact and cause of death (undisputed, confirmed by post-mortem); the unlawful act by the appellant (established by the circumstantial evidence); and malice aforethought under Section 206, satisfied by the deliberate and forceful strangulation causing broken neck bones.
Adequacy of investigations and absence of independent witnesses
The absence of neighbours or independent witnesses did not create a fatal gap; the prosecution need not call a multitude of witnesses where available evidence suffices, and nothing stopped the appellant from calling the neighbours in his defence.
The court rejected the complaint of shoddy investigation, relying on Francis Mwangi Wanjohi for the proposition that the prosecution need not call a multitude of witnesses. It noted the appellant never named the neighbours he had in mind and could have called them himself. The circumstantial chain was complete and unbroken.
Suspicion versus proof
This was not a conviction on mere suspicion; there was overwhelming circumstantial evidence tying the appellant to the crime, consistent with Joan Chebichii Sawe that suspicion however strong cannot found a conviction.
Counsel for the appellant argued conviction on suspicion, citing Joan Chebichii Sawe v Republic. The court acknowledged that holding but distinguished it, finding sufficient circumstantial evidence connecting the appellant to the crime rather than mere suspicion.
Legal principles established
#- When a case rests entirely on circumstantial evidence, three conditions must be satisfied: the circumstances must be cogently established, must have a definite tendency pointing to the guilt of the suspect and no other, and taken cumulatively must form a complete chain leading only to the conclusion that the suspect committed the crime.
- Under the doctrine of last seen, the person last seen with the deceased bears full responsibility for the death and must give a satisfactory explanation of how the deceased met death, failing which an inference of guilt may be drawn.
- The prosecution is not obligated to call a multitude of witnesses if the available evidence sufficiently proves the case.
