#Sufficiency of circumstantial evidence to sustain a murder conviction
The circumstantial evidence (CCTV ATM withdrawals, use of the deceased's handset with the appellant's sim card, motive from a mercury con) cumulatively met the threshold and pointed irresistibly to the appellant's guilt.
The court applied the Koskei and Ndurya formulation: inculpatory facts must be incompatible with innocence and exclude any other reasonable hypothesis, with no weakening co-existing circumstances. The appellant's defence that Daudi gave him the ATM card was a mere denial contradicted by the CCTV footage and Safaricom data showing his sim card in the deceased's handset after the disappearance. That only two CCTV images were produced did not weaken the chain.
Whether motive was necessary or relevant
Motive need not be proved but is admissible and becomes an important element in the chain of presumptive proof where a case rests on purely circumstantial evidence.
Relying on Choge v Republic and Libambula v Republic, the court held that the appellant's motive - recovering money swindled by the deceased through the fake red mercury sale - completed the inferential chain. The witnesses to the mercury deal had no reason to lie since the appellant himself led police to them.
Malice aforethought
Malice aforethought was established, being readily inferable from the nature of the injuries: multiple fractures, bruises and multiple stab wounds to the neck.
The post mortem by Dr. Njau showed multiple fractures on the face and head, chest bruises and multiple stab wounds mainly on the neck, with stab wounds as the cause of death. The court held the appellant had the intention to cause death, so this ground of appeal had no merit.
Sentence - mandatory death penalty
The death sentence was set aside and substituted with 30 years imprisonment, taking into account that the appellant was a first offender who had been in custody nearly 8 years before sentencing, but also the torturous manner of the killing.
In light of Muruatetu, the mandatory death sentence is unconstitutional and courts must individualise sentences considering the circumstances of each case and any mitigation. Weighing the appellant's status as a first offender and time in custody against the painful and torturous manner of death, thirty years imprisonment was imposed effective from the date of the trial sentence.
Legal principles established
#- For a conviction on circumstantial evidence, the inculpatory facts must be incompatible with the innocence of the accused and incapable of explanation on any other reasonable hypothesis, with no co-existing circumstances weakening the chain; the burden never shifts to the accused.
- On a first appeal, the Court of Appeal is obliged to re-analyse and re-evaluate the evidence of the trial court and reach its own findings and conclusions.
- Malice aforethought may be inferred from the nature of the injuries inflicted on the deceased.
- Following Muruatetu, a mandatory death sentence is not the only sentence available for murder; the court must consider the circumstances of each case, mitigation, and impose an appropriate sentence including the death penalty where deserved.
