Marwa Magige Kieusi & 1 other v Republic
The bottom line
#Kenya's Court of Appeal upheld two murder convictions based on circumstantial evidence but backdated the 35-year sentences to count time spent in remand.
What this practically means
#Executive summary
#Key legal issues
#Whether the circumstantial evidence met the threshold for conviction
Yes - the chain was complete: the appellants were the last seen with the deceased, had exclusive access to the compound, keys were found in their quarters, there was no evidence of break-in, and they fled to Tanzania.
The Court applied the three-limb Abanga test. PW3 and PW6 placed the appellants at the scene on 4th and 5th June 2020. No forced entry occurred, so no outsider could enter without the appellants' knowledge. The unexplained flight of the 2nd appellant to Morogoro on the day the body was discovered, and the appellants' failure to explain who killed the deceased, completed the chain.
Whether the alibi defence displaced guilt
No - the alibi was disproved by prosecution evidence placing the appellants at the deceased's home on 4th and 5th June 2020.
While the burden of disproving an alibi lies on the prosecution, PW3 and PW6's testimony placed the appellants in the compound at the material time, making them the last people seen with the deceased. The 2nd appellant's departure for Morogoro on the very day the murder was discovered, while police looked for him, undermined the alibi.
Whether malice aforethought was proved
Yes - the gravity and multiplicity of the injuries and the concealment of the body demonstrated intent to kill.
The postmortem showed five deep cut wounds to the head and back, a chopped-off arm and a severed wrist. The trial court's finding that the injuries were meant to end life, and the conduct of dragging the body into a water tank and fleeing, proved malice aforethought under section 206 of the Penal Code. The Court affirmed this finding.
Whether the 35-year sentence was lawful and whether time in remand should count
The sentence was lawful, but section 333(2) of the Criminal Procedure Code required the remand period to be reckoned.
Although the offence carried a death sentence and the trial court properly considered mitigation and the brutality of the killing, it failed to account for the period the appellants spent in remand. The Court thus dismissed the appeal but ordered the sentence to run from each appellant's date of production in court.
Whether the unexplained unknown DNA on the bloodstained cloth exculpated the appellants
No - the omission of samples from the appellants could not exculpate them given the otherwise complete chain of circumstances.
The government analyst matched blood on the pangas to the deceased, but blood on the cloth found in the servant quarters belonged to an unknown male, and no samples were taken from the appellants. The Court acknowledged the gap but held it was outweighed by the cumulative circumstantial evidence pointing to the appellants alone.
Legal principles established
#- Where a case rests entirely on circumstantial evidence, the circumstances must be cogently and firmly established, point unerringly to guilt, and form a complete chain excluding any other conclusion.
- An accused who raises an alibi bears no burden of proving it; it is sufficient if it introduces an unreasonable doubt, and the burden of disproving it lies on the prosecution.
- The last-seen-with doctrine alone is insufficient to convict on circumstantial evidence; it must combine with other circumstances excluding innocence.
- On first appeal, the appellate court must re-evaluate the evidence, draw its own inferences, and give allowance for not having seen the witnesses testify.
- Sentences must take into account the period an accused spent in remand custody during trial.
