Statements by co-conspirators are statements made by one or more participants in a criminal conspiracy that can be used as evidence in a criminal trial. They are statements made to or overheard by one of the co-conspirators which can be used to prove the existence of a conspiracy and the participation of those involved. These statements can be made to other participants in the conspiracy, or to other people not involved in the conspiracy. The two main types of statements by co-conspirators are admissible and non-admissible. Admissible statements are those made during the course of the conspiracy and are considered to be reliable. Non-admissible statements are those made after the criminal conspiracy has been terminated and are not considered to be reliable. These statements may include verbal conversations, written letters or emails, text messages, or anything else that can be used as evidence in a criminal trial. They can be used to prove the existence of the conspiracy, the roles of the participants, and the actions taken by the participants.
