Key legal issues
#Ingredients of murder
The fact and cause of death were proved by post-mortem evidence; the contested element was whether the appellant was the perpetrator.
The Court restated the three elements of murder: death and its cause, the accused's commission of the unlawful act, and malice aforethought, all to be proved beyond reasonable doubt. The pathologist's post-mortem reports confirmed death by deep cut wounds inflicted with sharp and blunt objects, and the appellant conceded the fact and cause of death, contesting only responsibility.
Conviction on circumstantial evidence
The circumstantial evidence formed an unbroken chain: presence at the oath-taking venue by phone triangulation, arrest fleeing the murder scene with the 1st accused who carried the blood-stained panga, and possession of MRC ribbons.
Applying Koske, Sawe and Kahiga, the Court found the inculpatory facts incompatible with innocence and incapable of explanation on any other hypothesis. The testimonies of PW2 and PW7 were corroborative and uncontroverted; discrepancies were minor. The alibi failed because DW2 could not account for the appellant after 6.00 p.m. on the night of the murders.
Common intention under section 21 of the Penal Code
The appellant was liable as an accessory under the doctrine of common intention even though the forensic evidence related only to one deceased officer.
The Court applied the ingredients in Eunice Musenya Ndui and R v Jogee: the appellant took part in oathings whose participants were dispatched to disrupt elections and attack those overseeing them; common intention may develop in the course of the offence. His presence, flight and association with the armed 1st accused permitted the inference of shared intent to kill election overseers.
Malice aforethought
Malice aforethought was established from the nature of the vicious attacks aimed at vital organs.
Applying section 206 of the Penal Code and Nzuki, the Court held that the multiple machete cuts to heads, jaws and limbs of the four officers demonstrated an intention to cause death or grievous harm, so as to enable MRC members to continue disrupting the elections.
Sentence
The death sentence was upheld as commensurate, denouncing and deterring the callous murders of police officers on election duty.
Guided by Kogo and Omuse, the Court found no error of principle or manifest excess. Under the Judiciary Sentencing Policy Guidelines 2023, the objectives of retribution, deterrence and denunciation were met; killing law enforcers during general elections warranted the maximum penalty.
Legal principles established
#- A first appellate court must re-appraise the evidence and draw its own inferences of fact while making allowance for not having seen or heard the witnesses.
- Circumstantial evidence may sustain a conviction only if it forms a complete and unbroken chain excluding every other reasonable hypothesis than guilt.
- Under section 21 of the Penal Code, a person who shares a common intention to prosecute an unlawful purpose is deemed to have committed an offence that is a probable consequence of that purpose.
- An appellate court will not interfere with sentence unless the trial court considered irrelevant matters, failed to consider relevant ones, applied a wrong principle, or the sentence is manifestly excessive or illegal.

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.
The upshot of the above is that the appellant's appeal fails and is hereby dismissed in its entirety. We uphold both his conviction and sentence and accordingly affirm the Judgment of the High Court at Mombasa (Muya, J.) delivered on 29th July 2016.
we find no reason to interfere with the sentence meted out on the appellant, and accordingly uphold the death sentence imposed by the High Court.
the inculpatory facts are incompatible with the innocence of the appellant and incapable of explanation upon any other reasonable hypothesis than that of his guilt
It matters not that the forensic evidence produced in court related only to PC Maithya. Critical is the fact that there was common intention to kill anyone who was to oversee the smooth running of the elections.
Our mandate involves revisiting the evidence presented to the trial judge, conducting an independent analysis thereof, and subsequently drawing our conclusions.
Issues in the judgment
#Appellant's arrest date recorded as 2012 instead of 2013 in his testimony
Court says killings took place 'the following day' after oath-taking, though both are elsewhere placed on the night of 3rd March 2013
PW3 is recorded both as Sgt. Josephine Mwangemi and as Hussein Ali, an acknowledged recording error
