The bottom line

#

Kenya's Court of Appeal upheld a 40-year murder conviction, confirming that strong circumstantial evidence can prove guilt even without eyewitnesses.

What this practically means

#

Executive summary

#
This is a first appeal from the High Court at Nyeri, where the appellant was convicted of the murder of Teresiah Wangechi Mwangi contrary to section 203 as read with section 204 of the Penal Code and sentenced to 40 years imprisonment running from the date of his plea; the companion count relating to the death of her toddler son was dismissed at trial. The appeal was heard by M’Inoti, ole Kantai and Ali-Aroni JJA, who delivered a single judgment dismissing the appeal in its entirety on 6th March 2026. The court re-appraised the evidence under rule 31(1)(a) of the Court of Appeal Rules, 2022. It held that malice aforethought was established from the deep cut to the neck, applying the Tubere factors. On identity of the perpetrator, the case rested on circumstantial evidence: the appellant's clothes worn on the day of the murder were found buried near the scene, he disappeared immediately after the killing, and upon arrest ten months later he led police to the buyer of the deceased's mobile phone, whose purchase was proved by a receipt bearing the serial number. The court found these inculpatory facts incompatible with innocence and incapable of any other hypothesis than guilt, applying the three-part Abanga test and the burden of proof principles. The complaint that vital witnesses were not called failed, section 143 of the Evidence Act requiring no particular number of witnesses, and the alibi was properly displaced. The sentence challenge also failed because the sentence was expressly directed to run from the plea date, accounting for time in custody. The conviction and sentence were affirmed.

Questions the Court framed

#

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

  1. 1.Whether malice aforethought was proved
  2. 2.Whether the circumstantial evidence was sufficient to identify the appellant as the perpetrator and sustain the conviction
  3. 3.Whether the failure to call certain witnesses (the employer and Chepkemo's corroboration) vitiated the prosecution case
  4. 4.Whether the appellant's alibi defence was properly rejected
  5. 5.Whether the sentence of 40 years was manifestly excessive or failed to account for time spent in custody

Key legal issues

#
01

Proof of malice aforethought

Holding

Malice aforethought was established from the nature of the weapon used and the part of the body targeted, the neck being almost severed.

Reasoning

Applying the Tubere factors (weapon, manner of use, part of body targeted, nature of injuries, conduct of accused), the court held that a deep cut to the neck severing the spine is a clear indication of intent to cause death. The ground attacking malice aforethought therefore failed.

p. 5
02

Sufficiency of circumstantial evidence to identify the perpetrator

Holding

The chain of circumstances - burial of the appellant's clothes near the scene, his disappearance, his arrest months later, and his sale of the deceased's phone - supported the inference of guilt beyond reasonable doubt.

Reasoning

The court re-appraised the evidence, found the circumstances cogently established, of a definite tendency unerringly pointing to guilt, and forming a complete chain. The receipt with the serial number proved the phone was the deceased's, and the appellant led police to the buyer. The alibi was displaced by the strong prosecution case.

p. 7
03

Failure to call vital witnesses

Holding

Section 143 of the Evidence Act requires no particular number of witnesses; calling the employer would not have added value since Chepkemo testified to the sale of the phone.

Reasoning

Relying on Bukenya v Uganda, the court held the Director has a discretion over material witnesses. The prosecution case was not about the employment but about the sale of the phone during it, which Chepkemo proved. The complaint on uncalled witnesses was therefore without merit.

p. 7
04

Sentence

Holding

The 40-year sentence running from the date of plea was proper and took into account time in custody.

Reasoning

The appellant took plea on 22nd October 2008 and was never released on bail; the trial court directed the sentence to run from the plea date. The complaint that custody time was ignored was factually incorrect, and sentence remains at the discretion of the trial court (Bernard Kimani Gacheru).

p. 8

Legal principles established

#
  • On a first appeal from a superior court exercising original jurisdiction, the Court of Appeal has power to re-appraise the evidence and draw inferences of fact.
  • In a case depending exclusively on circumstantial evidence, the inculpatory facts must be incompatible with the innocence of the accused and incapable of explanation on any other hypothesis than guilt, and the burden of excluding other reasonable hypotheses never shifts to the accused.
  • The prosecution has a discretion as to which witnesses to call, subject to the duty to call all witnesses necessary to establish the truth; a failure to call a witness whose evidence is merely cumulative does not vitiate the case.

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.

This appeal fails in its entirety and is dismissed.
p. 8Final orders and disposition
The conclusion of all the above is that the prosecution’s case was proved beyond reasonable doubt and the appellant was rightly convicted of the charge he faced.
p. 8Standard of proof satisfied on circumstantial evidence
Those inculpactory facts are incompatible with the innocence of the appellant and are incapable of any explanation other than his guilt- See Republic vs. Kipkering Arap Koskei & Another [1949] XVI EACA 135.
p. 7Circumstantial evidence test applied
The burden of proving facts that justify the drawing of this inference from the facts to the exclusion of any other reasonable hypothesis of innocence remains with the prosecution. It is a burden, which never shifts to the party accused.
p. 7Burden of proof in circumstantial cases
In sentencing, on 31st January, 2019, the court clearly indicated that the sentence would run from the date when he took plea. There is no reason to review that proper order.
p. 8Sentencing and time in custody

Issues in the judgment

#
minor

The judgment states the respondent wrongly described the sentence as a death sentence, whereas the actual sentence was 40 years imprisonment.

minor

The judgment dates the conviction judgment as 25th January 2019 but refers to sentencing on 31st January 2019, a six-day discrepancy.
