David Njeru Kibuthu & others v Republic [2005] KECA 304 (KLR)
The bottom line
#Kenya's Court of Appeal quashed a robbery conviction because tracker dog evidence lacked proof of the dog's training, but upheld convictions based on fingerprints at the scene.
What this practically means
#Executive summary
#Key legal issues
#Reliability and sufficiency of tracker dog evidence
A conviction cannot safely rest on tracker dog evidence where there is no evidence of the dog's training and experience and no expert evidence as to a tracker dog's ability to distinguish between the scents of several persons at a scene.
The court found nothing on the record establishing Omas's competence: the magistrate's remark that the dog was 'well trained in tracking' was unsupported by any witness, and the handler PW5 made no such claim. Where several robbers touched items and left the scene, the significance of the dog following a particular scent cannot be weighed without expert evidence of what a tracker dog can and cannot do. Absent that, the tracking evidence had no ascertainable probative value.
Whether the tracker dog's tracking alone could sustain a conviction
It is unsafe to rely solely on the fact that a tracker dog led the police to where an accused was found; corroboration by other evidence is required.
Applying that principle to the second and third appellants, the court held that the dog's picking up and following the scents of two different people from the same starting point, without any evidence of what a tracker dog can or cannot do, seemed unlikely and could not alone sustain a conviction. Their convictions were saved only by the independent fingerprint evidence placing them inside the complainant's house on the night of the robbery.
Effect of inconsistencies between the two tracking officers
The differences between the evidence of PW5 and PW7 as to how the 1st appellant was apprehended by the dog were not sufficient to raise doubts as to the truth of their evidence.
Counsel for the appellants, Mr Patrick Kiage, argued that inconsistencies between the two officers' accounts of the dog's apprehension of Kibuthu undermined the prosecution case. Having set out both officers' testimony in full, the court found no material contradiction capable of creating reasonable doubt. The 1st appellant's conviction nonetheless failed because the dog evidence was itself unsupported by evidence of the animal's training and capability and no other evidence connected him to the offence.
Proof of the 1st appellant's guilt to the required standard
Where the accused is identified by no witness, no stolen property is traced to him, his fingerprints are not found at the scene and the only other evidence is deficient tracker dog evidence, his guilt is not proved beyond reasonable doubt.
The court catalogued the absence of any evidence connecting Kibuthu to the robbery: no complainant recognised him, none of the stolen items was traced to him and his prints were not found in the house. With the tracker dog evidence unsafe for want of expert support, nothing remained to prove guilt to the criminal standard. The court was fortified by the decision of Senior State Counsel Mr Orinda not to support the conviction.
Probative value of fingerprint evidence recovered at the scene
Fingerprints lifted from inside the complainant's house matching an accused, coupled with the absence of any evidence that he had ever been in or near the house before, prove that he was in the house on the night of the robbery and took part in it.
PW9 lifted ten prints from various surfaces at about 10.30 a.m. on the day after the robbery and submitted them with elimination prints to the Criminal Records Office, which matched Lift No. 2 to Kinyua and Lift Nos. 4 and 8 to Mwendwa. Both courts below accepted the evidence without doubt. Since neither accused was ever shown to have been in or near the house previously, the only reasonable inference was presence as part of the robbery gang, corroborated by the dog leading police to them.
Legal principles established
#- A conviction cannot safely be founded on tracker dog evidence unless evidence is adduced of the dog's training and experience and expert evidence as to what a tracker dog can and cannot do.
- It is unsafe to convict solely on the fact that a tracker dog led the police to where an accused person was found; independent corroborative evidence is required.
- Where an accused's fingerprints are found at the scene of a robbery and there is no evidence that he was ever in or near the premises on any previous occasion, the fingerprint evidence establishes his presence and participation in the offence.
- Guilt must be proved beyond reasonable doubt; where the only linking evidence is deficient and no other evidence connects the accused to the offence, the conviction cannot stand.
