What do you call a person who assists in the commission of a crime?

The term used to describe a person who assists in the commission of a crime is "Accessory." An accessory is someone who helps another person commit a crime, either before or after the crime has been committed. This assistance can take various forms, such as providing resources, planning the crime, or helping the perpetrator evade capture after the crime has occurred.

The distinction between an accessory and other terms is important. While a principal directly participates in the crime, an accessory may not be present at the scene but still contributes to the commission of the crime in significant ways. Understanding these roles helps clarify the legal terminology associated with criminal activities and the varying degrees of involvement individuals may have in those activities.
