MODEL PENAL CODE
Section 5.01. Criminal Attempt.
(1) Definition of Attempt. A person is guilty of an attempt to commit a crime if, acting with the kind of culpability otherwise required for commission of the crime, he:
(a) purposely engages in conduct which would constitute the crime if the attendant circumstances were as he believes them to be; or
(b) when causing a particular result is an element of the crime, does or omits to do anything with the purpose of causing or with the belief that it will cause such result without further conduct on his part; or
(c) purposely does or omits to do anything which, under the circumstances as he believes them to be, is an act or omission constituting a substantial step in a course of conduct planned to culminate in his commission of the crime.
(2) Conduct Which May Be Held Substantial Step Under Subsection (1)(c). Conduct shall not be held to constitute a substantial step under Subsection (1)(c) of this Section unless it is strongly corroborative of the actor's criminal purpose. Without negativing the sufficiency of other conduct, the following, if strongly corroborative of the actor's criminal purpose, shall not be held insufficient as a matter of law:
(a) lying in wait, searching for or following the contemplated victim of the crime;
(b) enticing or seeking to entice the contemplated victim of the crime to go to the place contemplated for its commission;
(c) reconnoitering the place contemplated for the commission of the crime;
(d) unlawful entry of a structure, vehicle or enclosure in which it is contemplated that the crime will be committed;
(e) possession of materials to be employed in the commission of the crime, which are specially designed for such unlawful use or which can serve no lawful purpose of the actor under the circumstances;
(f) possession, collection or fabrication of materials to be employed in the commission of the crime, at or near the place contemplated for its commission, where such possession, collection or fabrication serves no lawful purpose of the actor under the circumstances;
(g) soliciting an innocent agent to engage in conduct constituting an element of the crime.
(3) Conduct Designed
to Aid Another in Commission of a Crime. A person who engages
in conduct designed to aid another to commit a crime which would establish
his complicity under Section 2.06
if the crime were committed by such other person, is guilty of an attempt
to commit the crime, although the crime is not committed or attempted by
such other person.
(4) Renunciation of Criminal Purpose. When the actor's conduct would otherwise constitute an attempt under Subsection (1)(b) or (1)(c) of this Section, it is an affirmative defense that he abandoned his effort to commit the crime or otherwise prevented its commission, under circumstances manifesting a complete and voluntary renunciation of his criminal purpose. The establishment of such defense does not, however, affect the liability of an accomplice who did not join in such abandonment or prevention.
Within the meaning of this Article, renunciation of criminal
purpose is not voluntary if it is motivated, in whole or in part, by circumstances,
not present or apparent at the inception of the actor's course of conduct,
which increase the probability of detection or apprehension or which make
more difficult the accomplishment of the criminal purpose. Renunciation
is not complete if it is motivated by a decision to postpone the criminal
conduct until a more advantageous time or to transfer the criminal effort
to another but similar objective or victim.
