Driver in Robbery-Murder
Paula Pierce remained in the getaway car outside the store while the principals entered and committed the robbery that resulted in death. Her role supplied contemporaneous aid and a means of escape at the scene. The question of liability hinges on whether that presence and assistance qualifies under the common-law category.

Common questions
Frequently Asked
3
What distinguishes a principal in the second degree from an accessory before the fact?+
The key distinction is presence at the scene. A principal in the second degree must be actually or constructively present while aiding or encouraging the principal in the first degree. An accessory before the fact provides aid or encouragement but remains absent from the scene during the crime.
Supporting sources
Does constructive presence satisfy the presence requirement?+
Yes. A person is constructively present when positioned nearby with the ability to assist, such as waiting just outside the immediate location in a running vehicle ready to aid escape or warn of detection.
Supporting sources
How does the common-law category affect modern liability?+
Modern statutes have largely abolished the procedural distinctions among the four categories, yet the substantive definition of a principal in the second degree continues to identify those who aid at the scene and are therefore treated as principals rather than accessories.
