Benson Kimathi Marangu v Republic
The bottom line
#Kenya's Court of Appeal upheld a 40-year murder sentence, confirming that a complete chain of circumstantial evidence can convict without an eyewitness.
What this practically means
#Executive summary
#Key legal issues
#Whether death occurred and was caused by the unlawful act of the accused
Death was proved by eyewitnesses, family and three pathologists; the cause of death was multiple blunt trauma and mutilation consistent with violent assault, and the cumulative circumstantial evidence pointed exclusively to the appellant
The Court re-evaluated the evidence of child witnesses who identified the appellant, the soil analysis matching shoes from his house to the scene, call data placing him at the abduction site at 4 p.m., his false alibi and unexplained indifference, and applying the last-seen doctrine concluded the evidence was incompatible with innocence. The chain of circumstances was complete and excluded any co-existing hypothesis.
Whether malice aforethought was proved
Malice aforethought was established from the appellant's bitterness towards the deceased's mother and the vicious manner of the killing, fitting section 206 of the Penal Code
Motive was traced to the appellant's resentment at being jilted by PW10, evidenced by exchanged text messages, and the gruesome injuries inflicted on the child - blunt face injury, fractured knee joint, fractured sternum and multiple scalp fractures - spoke to the intention to kill or cause grievous harm within the meaning of section 206 of the Penal Code.
Whether the 40-year sentence was lawful
The sentence was found to be within the law and appropriate given the grisly killing of a young child
The Court found no reason to interfere with the sentence imposed by the trial court, holding it lawful and proportionate to an offence in which a young innocent child needlessly lost her life in the grisliest manner.
Legal principles established
#- On a first appeal, the Court must re-evaluate the evidence and reach its own independent determination
- An appellate court will not interfere with findings of fact by the trial court unless based on no evidence, misapprehension of the evidence, or wrong principles
- For a conviction on circumstantial evidence, the chain of events must be complete and exclude any other reasonable hypothesis of innocence
- Under the last-seen doctrine, an accused last seen with the deceased must give a satisfactory explanation of how the deceased met death, failing which an inference of guilt may be drawn
- Malice aforethought may be inferred from the vicious, gruesome manner in which the killing was executed
