A criminal charge of aiding and abetting is known as an accomplice crime, and may be brought against anyone who helps with the commission of a crime. Aiding and abetting charges vary from state to state (and under federal law), but generally require that the defendant knowingly and intentionally aided and abetted the principal(s) in each essential element of the underlying crime. A person charged with aiding and abetting is often not present when the underlying crime is committed, but has knowledge of the crime before the crime is committed, and assists with the commission of the crime by providing information, action, or financial support. If the person aiding and abetting has a sufficient degree of involvement in the crime, the participation may rise to the level of being a conspiracy to commit the underlying crime.

In Wyoming, aiding and abetting is addressed under the state's criminal laws and is considered an accomplice crime. According to Wyoming statutes, a person is criminally liable for the conduct of another if they are an accomplice to the other person in the commission of the crime. To be charged with aiding and abetting, the individual must have knowingly and with intent helped, encouraged, or supported the principal offender in committing the crime. This can include providing information, resources, or any form of assistance that facilitates the commission of the crime. Even if the accomplice is not present during the actual perpetration of the crime, they can still be held liable if their involvement meets the criteria for aiding and abetting. Furthermore, if the level of involvement is significant enough, it could potentially be considered a conspiracy to commit the crime in question. The penalties for aiding and abetting will typically correspond to the severity of the underlying crime that was committed.
