Circumstantial evidence is sufficient to sustain a criminal conviction when it consists of a set of facts or events which, by undesigned coincidence, point in one direction and lead to a compelling conclusion that leaves no doubt in a reasonable mind. The test is whether the circumstances are capable of proving a proposition with the accuracy of mathematics. When multiple pieces of circumstantial evidence converge - including presence near a crime scene, false and conflicting explanations, physical evidence linking the accused to the scene, and evidence of prior similar conduct - a court is justified in finding guilt beyond reasonable doubt. A confession by one co-accused cannot be used against another co-accused, but if the confession does not implicate the other accused, it does not constitute a basis for appeal by that other accused.
