Douglas Gitonga Mutembei v Republic
The bottom line
#Kenya's Court of Appeal quashed a murder conviction because police mishandled a confession and the remaining evidence could not link the accused to the crime.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the trial court erred in admitting and relying on the 1st accused's statement under inquiry without conducting a trial within a trial
- 2.Whether the circumstantial evidence, including the DNA evidence, established the appellant's guilt of murder
- 3.Whether the doctrines of common intention and 'last seen' were properly applied to convict the appellant
- 4.Whether the conviction and sentence of 12 years imprisonment were safe
Key legal issues
#Admissibility of the statement under inquiry/confession
The statement was inadmissible: it was not dated, taken without a third party, without the required caution, certificate or compliance with Section 25A of the Evidence Act and the Evidence (Out of Court Confession) Rules, and no trial within a trial was conducted despite the objection.
The court found a total disregard of Section 25A and the Confession Rules: no date, no third party of the accused's choice, no certificate from the recording officer or the accused, and the alleged recorder (IP Ekirapa) was never called to vouch for the statement. The trial judge summarily overruled the objection instead of holding a trial within a trial, a grave error. Following Owiti, Imbindi, Musili Tulo and Ndiba, the statement ought to have been excluded, and a conviction founded on it cannot stand.
Sufficiency of circumstantial and DNA evidence
Stripped of the inadmissible statement, no evidence connected the appellant to the defilement or murder; the DNA semen sample matched the 4th accused, not the appellant, and there was no evidence of gang rape.
The Government Analyst's DNA results implicated only the 4th accused. No prosecution witness saw the deceased with the appellant. The trial judge's findings of gang rape and defilement in turns by all four accused were unsupported by any evidence, so the doctrine of common intention had no factual foundation. Hearsay references to the appellant's unproduced statements were also improperly relied upon.
Application of the 'last seen' doctrine
The doctrine did not apply because it was not conclusively proved that the appellant was the last person seen with the deceased, and there was a significant time gap between the evening of 28th February and the morning of 29th February 2016 allowing for intervening events.
The appellant was with the deceased at about 5:00pm in the company of others including Mzee Musoma; the body was found around 7:00am the next morning. No witness testified as to when the appellant arrived home, and no evidence showed how the deceased's goats got home. The presumption arising from last seen was considerably weakened by the time lapse and the possibility of intervening events.
Legal principles established
#- Where an objection is raised to the admissibility of an extra-judicial/confessionary statement, the trial court must conduct a trial within a trial before admitting the statement; a conviction based on an inadmissible statement cannot stand.
- It is the person who recorded the impugned statement who should present it for production, subject to cross-examination, unless for good reason recorded he cannot attend.
- Where no trial within a trial is held, the impugned statement ought to be excluded.
- The 'last seen' doctrine requires conclusive proof that the accused was the last person seen with the deceased, with minimal time gap; a significant time gap weakens the presumption.
- On a first appeal, the Court of Appeal must re-evaluate the evidence and reach its own independent conclusions while allowing for the fact that it neither saw nor heard the witnesses.

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.
For the foregoing reasons, we are not persuaded that the conviction of the appellant was safe and we hereby quash it and set aside the sentence. The appellant to be set forth at liberty unless otherwise lawfully held under a separate warrant.
We reiterate that immediately there is a challenge to an extra-curial statement being introduced in evidence, then a court must hold a trial within a trial before such statement may be produced as an exhibit, or otherwise admitted in evidence.
Where no trial within a trial is held such statements ought to be excluded as elaborated in the case of Musili Tulo v R (supra). Consequently, a conviction based on a statement which ought not to have been admitted in the first place cannot stand.
Before the 'Last Seen' doctrine can apply, there must be conclusive proof that the person was in fact the last person seen with the deceased, so that an explanation may be required from the person charged to explain the circumstances leading to the death of the deceased.
There is no evidence of gang rape, or that the deceased was defiled by more than one person.
Issues in the judgment
#Judgment contradicts itself on which accused absconded: para 2 says the 1st and 3rd accused absconded from 16th January 2017, while para 6 says the 1st and 4th accused absconded after PW4 testified.
The judgment repeatedly refers to '29th February 2016', a date that did not exist, as the date the body was found.
