3.04 Circumstantial Evidence A fact or a group of facts may, based on logic and common sense, lead you to a conclusion as to other facts. This is known as circumstantial evidence. A fact may be proved by circumstantial evidence. [For example, if you are in a building and a person enters who is wet and is holding an umbrella, you might conclude that it was raining outside.] Circumstantial evidence is entitled to the same consideration as any other type of evidence.
