(1) The offense of conspiracy is committed if two (2) or more people, each having the culpable mental state required for the offense that is the object of the conspiracy, and each acting for the purpose of promoting or facilitating commission of an offense, agree that one (1) or more of them will engage in conduct that constitutes the offense.
(2) If a person guilty of conspiracy, as defined in subsection (a), knows that another with whom the person conspires to commit an offense has conspired with one (1) or more other people to commit the same offense, the person is guilty of conspiring with the other person or persons, whether or not their identity is known, to commit the offense.
(3) If a person conspires to commit a number of offenses, the person is guilty of only one (1) conspiracy, so long as the multiple offenses are the object of the same agreement or continuous conspiratorial relationship.
(4) No person may be convicted of conspiracy to commit an offense, unless an overt act in pursuance of the conspiracy is alleged and proved to have been done by the person or by another with whom the person conspired.
(5) Conspiracy is a continuing course of conduct that terminates when the objectives of the conspiracy are completed or the agreement that they be completed is abandoned by the person and by those with whom the person conspired. The objectives of the conspiracy include, but are not limited to, escape from the crime, distribution of the proceeds of the crime, and measures, other than silence, for concealing the crime or obstructing justice in relation to it.
(6) Abandonment of a conspiracy is presumed if neither the person nor anyone with whom the person conspired does any overt act in pursuance of the conspiracy during the applicable period of limitation.
(7) If an individual abandons the agreement, the conspiracy is terminated as to that person only if and when the person, advises those with whom the person conspired of the abandonment, or the person informs law enforcement authorities of the existence of the conspiracy and of the person's participation in the conspiracy.
(8) It is no defense that the offense that was the object of the conspiracy was not committed.
(9) Nothing in this section is intended to modify the evidentiary rules allowing statements of co-conspirators in furtherance of a conspiracy.
