Where circumstantial evidence points to collusion between co-accused employees whose duties are complementary and who both had custody of stolen property, and the property disappeared while under their watch, such evidence is sufficient to prove guilt beyond reasonable doubt. The State is not obliged to indulge in conjecture and find an answer to every possible inference which ingenuity may suggest, nor is the court called upon to seek speculative explanations for conduct which on the face of it is incriminating (applying S v Sauls 1981 (3) SA 172 (A)). In applying principles of circumstantial evidence, the facts proved must be consistent with guilt and inconsistent with any reasonable hypothesis of innocence. When sentencing for theft of motor vehicles involving breach of trust by employees, courts must balance mitigating factors (such as family responsibilities and lack of personal benefit) against aggravating factors (such as seriousness of offence, moral blameworthiness, breach of trust, and premeditation).
