Attempt

An attempt to commit a crime consists of an intent to commit the target offense plus an act going far enough toward its completion — short of completion — to constitute a punishable step.

Elements / Test

Two elements required:

  1. Mens rea: Specific intent (purpose) to commit the target crime — recklessness or negligence is insufficient for attempt even if sufficient for the completed crime
  2. Actus reus: A substantial step toward commission

Tests for the actus reus (jurisdictions vary):

  • Substantial step (MPC § 5.01): Act that is “strongly corroborative of the actor’s criminal purpose” — e.g., lying in wait, enticing victim, reconnoitering, unlawful entry. Most used test.
  • Dangerous proximity test: Act must be “dangerously proximate” to completion (People v. Rizzo — defendant drove around looking for victim, never found him; conviction reversed)
  • Last proximate act: Must have performed the last act necessary for completion (very narrow; nearly abandoned)
  • Unequivocality test: Acts must unequivocally manifest criminal intent from objective observer

Exceptions and Edge Cases

  • Factual impossibility: No defense — defendant intended the crime and did everything within their power (e.g., picking an empty pocket)
  • Legal impossibility: Traditional defense — if the completed act would not be a crime, there can be no attempt. MPC abolishes the distinction (§ 5.01(1))
  • Voluntary abandonment (MPC § 5.01(4)): Complete and voluntary renunciation — must be (1) voluntary (not due to increased risk of detection) and (2) complete (not just postponed). Affirmative defense.
  • Merger doctrine: Attempt merges into the completed offense — cannot be convicted of both
  • Attempt to attempt: Generally not punishable; solicitation and conspiracy may cover this gap

Policy Rationale

Punishes dangerous actors before harm occurs; incapacitation and deterrence rationale. Concern: punishing mere intent without sufficient overt act threatens to penalize thought. Tests balance crime prevention vs. liberty.

Key Cases

CaseRule
People v. Rizzo (N.Y. 1927)Dangerous proximity test; driving around looking for victim without finding him insufficient
United States v. Jackson (1977)Substantial step test; defendants who staked out bank had committed attempt
State v. Reeves (Tenn. 1996)MPC substantial step — girl’s notes showing plan to poison teacher = attempt
