Examples3
Tool Theft at Construction Site
Flora Ford smashed the lock on a tool trailer and removed equipment while Frederick Ferguson waited nearby in a running truck ready to signal any approach. After the theft, Francesca Fowler arranged resale and concealed records. At common law the classifications turn on who performed the core acts, who aided while present, and who assisted only afterward.
Warehouse Laptop Removal
Fumiko Fujimoto entered the warehouse alone, loaded laptops into a vehicle, and drove them away. Other participants supplied plans or distracted guards but did not perform the taking. Liability as principal in the first degree requires personal commission of the criminal act itself.
Lookout at Loading Dock
Fairfield Bank stood at the warehouse entrance and distracted the guard while Flagship Logistics loaded stolen goods inside. The assistance occurred at the scene during the crime. Classification as principal in the first degree requires personal commission of the criminal act itself.
Frequently Asked1
How does common law distinguish a principal in the first degree from a principal in the second degree?+
A principal in the first degree personally commits the criminal act. A principal in the second degree aids or encourages while present at the scene. The distinction rests on who performs the essential acts versus who assists contemporaneously.

Kidnapping During Protest Negotiations
Faye Fuller directed a locked vehicle across state lines and confined Farah Fox in a remote cabin for three days with armed guards to halt regulatory pressure. The confinement lasted a substantial period in isolation and served an unlawful purpose. Under the Model Penal Code the offense grades as first-degree unless the victim is released alive and safe before trial.
Aggravated Rape During Social Encounter
Foster Forge engaged in non-consensual intercourse with a woman he had just met at a party. He inflicted serious bodily injury during the act. The injury elevates the offense to rape graded as first-degree under the Model Penal Code.
Life Sentence Proportionality Challenge
Fusion Power received a mandatory life term without parole for a first-degree offense. The defendant had no prior violent record. The Eighth Amendment analysis examines whether the sentence is grossly disproportionate to the crime and to sentences for other offenses in the jurisdiction.

Frequently Asked2
When does the Model Penal Code reduce kidnapping from a first-degree to a second-degree felony?+
Kidnapping is a felony of the first degree unless the actor voluntarily releases the victim alive and in a safe place prior to trial. The release must occur before trial begins.
Supporting sources
What facts elevate rape to a first-degree felony under the Model Penal Code?+
Rape becomes a felony of the first degree when the actor inflicts serious bodily injury or when the victim was not a voluntary social companion and had not previously permitted sexual liberties. Either aggravating circumstance raises the grade from second to first degree.
