Conspiracy; proof

There is conspiracy when two or more persons come to an agreement concerning the commission of a felony and decide to commit it.[1] Although direct proof is not essential to establish conspiracy, it must be established by positive and conclusive evidence.[2] Proof, not mere conjectures or assumptions, should be preferred to indicate that the accused had taken part in it.[3] Mere allegation and speculation is not evidence, and is not equivalent to proof.[4]
