Final answer:
The corpus delicti of robbery, or the fact that a robbery took place and the accused's connection to it, can indeed be proven entirely by circumstantial evidence, which includes motive, opportunity, and post-crime behavior.
Step-by-step explanation:
The concept of corpus delicti translates to 'body of the crime' and refers to the principle in criminal law which requires proof that a crime has actually occurred. In the context of robbery, corpus delicti would be the demonstrable fact that a robbery took place and that the defendant is linked to that crime. To answer the question, it's true that the corpus delicti of robbery can be proven entirely by circumstantial evidence. Circumstantial evidence includes things like motive, opportunity, or behavior after the crime that can be pieced together to infer guilt. An absence of direct evidence, such as a firsthand witness, does not necessarily preclude a verdict of guilty if the circumstantial evidence is compelling enough to meet the legal standards of proof.
