The bottom line

#

Kenya's Court of Appeal confirmed that a murder conviction can rest entirely on circumstantial evidence when the chain of facts points only to the accused.

What this practically means

#

Executive summary

#
The appellant, Boniface Mwakio Nyali, was convicted of murder contrary to section 203 as read with section 204 of the Penal Code and sentenced to 20 years imprisonment. The prosecution's case rested entirely on circumstantial evidence: nine witnesses testified, including evidence that the appellant told PW1 and PW2 that he had beaten the deceased after an alleged attempted sexual assault, and that the deceased was later found dead in a house locked from outside, with severe injuries. The appellant's defence that the deceased died from a throat ailment or a fall from bed was rejected as inconsistent with the post mortem findings of multiple stab wounds, rib and skull fractures, and blunt force trauma. On appeal, the appellant argued that the circumstantial and hearsay evidence was insufficient, that actus reus and mens rea were not established, and that malice aforethought was not proved. Counsel for both sides conceded the evidence was circumstantial; the respondent relied on the 'last seen' doctrine. The Court of Appeal, as the first appellate court, re-evaluated the evidence as required by Okeno v Republic. It applied the three-part test for circumstantial evidence from Abanga and Sawe v Republic, held that the chain of circumstances was complete and excluded any other reasonable hypothesis, and applied the 'last seen alive' doctrine, finding the appellant had a duty under section 111(1) of the Evidence Act to explain the death which he failed to discharge. It further inferred malice aforethought from the nature and targeting of the injuries under section 206 of the Penal Code. The Court affirmed the conviction and sentence and dismissed the appeal in its entirety.

Questions the Court framed

The issues the Court set itself to decide, in its own words.

  1. 1.Whether the prosecution proved the appellant's guilt beyond reasonable doubt
  2. 2.Whether the circumstantial evidence relied upon satisfied the tests for a conviction on circumstantial evidence, including the 'last seen' doctrine
  3. 3.Whether malice aforethought was established

Key legal issues

#
01

Sufficiency of circumstantial evidence to sustain a murder conviction

Holding

The circumstantial evidence met the three-part test: the appellant's admissions to PW1 and PW2, his exclusive access to the locked house, and injuries inconsistent with his defence formed a complete chain pointing only to him.

Reasoning

The court re-evaluated the evidence as the first appellate court. The appellant was living with the deceased, was the only person who knew the deceased was unwell, admitted an altercation to two independent witnesses, and the house was locked from outside. His defence of a fall or throat illness was inconsistent with the post mortem findings of stab wounds and blunt force trauma, and he failed to call the uncle he named as a witness.

p. 9
02

Application of the 'last seen' doctrine

Holding

Being the last person with the deceased, the appellant had a duty under section 111(1) of the Evidence Act to explain the death; his failure justified the inference of guilt.

Reasoning

Relying on Kimani v Republic, Dida Ali Mohammed and the Nigerian authority Stephen Haruna, the court held that the person last seen with the deceased bears responsibility absent a satisfactory explanation. The appellant neither reported the death nor sought medical or police help, and gave shifting accounts in chief and cross-examination.

p. 8
03

Malice aforethought

Holding

Malice aforethought was inferred from the nature, number and location of the injuries - multiple stab wounds and skull and rib fractures targeting the head, chest and neck.

Reasoning

Applying section 206 of the Penal Code and the authorities of Paul Muigai Ndungi, Daniel Muthee and Chesakit Matayo, the court held that malice may be construed from the circumstances of the attack. The severity and targeting of delicate body parts established an intention to cause death or grievous harm.

p. 10

Legal principles established

#
  • Where a case rests entirely on circumstantial evidence, the circumstances must be cogently established, point unerringly to guilt, and form a complete chain excluding any other reasonable hypothesis
  • Under the 'last seen alive' doctrine, the person last seen with the deceased bears an evidential burden to explain the death, and in the absence of a satisfactory explanation a court may infer that the accused killed the deceased
  • A first appellate court must re-evaluate and re-analyse the evidence and draw its own conclusions, while making allowance for the trial court's advantage of seeing and hearing the witnesses

Quotable passages

#

Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.

It is settled law that when a case rests entirely on circumstantial evidence, such evidence must satisfy three tests
p. 6Tests for circumstantial evidence
In order to justify on circumstantial evidence, the inference of guilt, the inculpatory facts must be incompatible with the innocence of the accused, and incapable of explanation upon any other reasonable hypothesis than that of his guilt.
p. 7Standard for drawing inference of guilt from circumstantial evidence
The doctrine of 'last seen alive' is based on circumstantial evidence where the law prescribes that the person last seen with the deceased before their death was responsible for his or her death and the accused is expected to provide an explanation as to what happened.
p. 8Last seen doctrine
The first appellate court must itself weigh conflicting evidence and draw its own conclusion
p. 5Duty of first appellate court
In view of the foregoing, we find that the prosecution proved its case beyond reasonable doubt. We hereby uphold the judgment of the High Court at Mombasa (Onyiego, J.) delivered on 14th July 2023. We find the appeal to be without merit and hereby dismiss it in its entirety.
p. 10Disposition - final orders

Issues in the judgment

#
minor

The judgment inconsistently records the year of death: the information alleges death on 27th November 2018, the witnesses' evidence is dated November 2018, but the trial court is said to have held that 'the deceased died on 27th November 2019'

minor

The judgment refers to upholding the judgment of the High Court at Mombasa while the charge was tried before the High Court at Voi
