That simply means that the Crown is relying upon evidence of various circumstances relating to the crime and the defendant which they say when taken together will lead to the sure conclusion that it was the defendant who committed the crime. It is not necessary for the evidence to provide an answer to all the questions raised in a case. .... the evidence must lead [a jury] to the sure conclusion that the charge which the defendant faces is proved against him. Circumstantial evidence can be powerful evidence, but it is important that [a jury] examine it with care, and consider whether the evidence upon which the [Crown] relies in proof of its case is reliable and whether does prove guilt. Furthermore, before convicting on circumstantial evidence [a jury] should consider whether [that evidence] reveals any other circumstances which are or may be sufficient reliability and strength to weaken or destroy the prosecution case. Finally, [a jury] should be careful to distinguish between arriving at conclusions based on reliable circumstantial evidence, and mere speculation."
