Dockworker Enters Locked Yard
Luis copied a master key and used it at night to unlock the fence around Seaway Shipping's secured cargo-container yard. He entered intending to break into a refrigerated container and steal luxury seafood. Port police arrested him inside the yard before he reached any container. His targeted entry into the fenced enclosure where he planned the theft satisfies the substantial-step requirement for attempted theft.

Common questions
Frequently Asked
3
Does unlawful entry into a fenced yard count as a substantial step for attempt?+
Yes. Under the Model Penal Code approach, unlawful entry into a structure, vehicle, or enclosure where the crime is contemplated qualifies as a substantial step when it strongly corroborates the actor's criminal purpose. The entry need not reach the precise object of the theft.
Supporting sources
Is entry into a locked hotel suite after hours a substantial step?+
Yes. When an actor uses an unauthorized master key to enter a locked suite intending to steal from the safe, the entry itself is the substantial step. It is not mere preparation because it places the actor inside the precise enclosure where the crime is planned.
Supporting sources
Does fleeing before touching the target property negate attempt liability?+
No. Once the defendant has unlawfully entered the enclosed area where the crime is to occur, the substantial step is complete. Abandonment after that point does not erase attempt liability unless the jurisdiction recognizes a complete and voluntary renunciation defense.
