A person commits Criminal Conspiracy if that person agrees with one or more persons to engage in or cause conduct constituting an offense, and any one or more of those persons act overtly to effect an objective of the conspiracy. The agreement need not be clearly stated. It may be implicit in the fact of collaboration or existence of other circumstances.
If a person knows or could expect that one with whom that person agrees, has agreed, or will agree with another to effect the same objective, that person is deemed to have agreed with the other, whether or not the other's identity is known.A conspiracy is deemed to continue until its objectives are accomplished, frustrated, or abandoned. "Objectives" include escape from the scene of the crime, distribution of booty, and measures, other than silence, for concealing the crime or obstructing justice in relation to it.
A conspiracy is deemed abandoned if no overt act to effect its objectives has been committed by any conspirator during the applicable period of limitations.
