How is a person involved in a crime, but not the main perpetrator, commonly referred to?

A person who is involved in a crime but not the main perpetrator is commonly referred to as an accessory. This term is used in legal contexts to identify someone who assists or supports the commission of a crime, often by either aiding the principal offender before or during the crime or helping them avoid capture afterward. Accessories play a role in the crime but do not directly carry out the criminal act themselves.

In many legal systems, being labeled as an accessory carries specific implications and potential legal consequences, as they may be charged for their involvement despite not being the primary actor in the crime. This differentiation is important for understanding the varying degrees of culpability that exist within criminal law.

The other terms mentioned can refer to slightly different roles in criminal activity. An accomplice, for example, typically works alongside the main offender, participating directly in the crime. Co-offender suggests that the person is engaged in the crime alongside another, implying direct involvement comparable to the perpetrator. Innocent would imply no involvement in the crime at all, which does not fit with the scenario described.
