DIRECT AND CIRCUMSTANTIAL EVIDENCE
There are two kinds of evidence; direct and circumstantial. Direct evidence is direct proof of a fact, such as testimony of an eyewitness. Circumstantial evidence is indirect evidence, that is, proof of a chain of facts from which you could find that another fact exists, even though it has not been proved directly. You are entitled to consider both kinds of evidence. The law permits you to give equal weight to both, but it is for you to decide how much weight to give to any evidence. It is for you to decide whether a fact has been proved by circumstantial evidence.
