Erickson Chengoli Wanyonyi v Republic [2018] KECA 542 (KLR)
The bottom line
#Kenya's Court of Appeal freed a man convicted of murder on circumstantial evidence, ruling that suspicion, however strong, cannot justify a conviction.

#Key legal issues
#Threshold for conviction on circumstantial evidence
The three circumstances found by the trial judge - last seen with the deceased, disappearance from the scene, and guilty conduct on reappearing - did not meet the required threshold; the possibility that another person accessed the shop was not excluded and the murder weapon was never forensically examined.
The court re-evaluated the timing evidence of Omweno and Dorothy, noting that the window in which the appellant could have killed the deceased was uncertain and that access by a third party was not ruled out. The weapon was not dusted for fingerprints or forensically examined, leaving the chain incomplete. The claimed motive rested on an unproven assertion that the couple were related, and witnesses described them as a loving, peaceful couple.
Admissibility of prejudicial documents
The psychiatric report recording the appellant's alleged admission and the post mortem form's history were irregularly admitted and appear to have improperly influenced the trial judge.
Under section 25A of the Evidence Act, an admission tending to prove guilt is admissible only if made in court or to a police officer of at least Chief Inspector rank who is not the investigating officer. The admission recorded by Dr. Judy Kamau did not satisfy this. The post mortem history that the deceased was murdered by her boyfriend was likewise prejudicial. The trial judge was required to act only on properly admitted evidence.
Motive and malice aforethought
No clear motive was established; the alleged clan relationship between the appellant and the deceased was never confirmed, and the inference of malice aforethought from the manner of killing could not substitute for proof that the appellant committed the offence.
The only evidence of the strained relationship came from the deceased's statements to her mother and Dorothy, with no independent confirmation that the parties were related. Other witnesses described the couple as happy and peaceful. Even if a strain existed, it did not establish malice aforethought where the appellant's commission of the offence was itself unproven.
Legal principles established
#- Circumstantial evidence justifying conviction must be cogently and firmly established, of definite tendency unerringly pointing to guilt, and cumulatively form a complete chain excluding any hypothesis other than the accused's guilt.
- A first appellate court must subject the evidence adduced at trial to a fresh and exhaustive examination and reach its own conclusions.
- A confession or admission tending to prove guilt made by an accused is inadmissible unless made in court or before a police officer of at least Chief Inspector rank who is not investigating the case.
- A court of law cannot convict on mere suspicion, however strong.
