What is the term for someone who intentionally conceals a crime they committed?

The correct term for someone who intentionally conceals a crime they committed is "Accessory." An accessory is a person who aids or contributes to the commission of a crime, or who helps the principal offender escape or avoid prosecution after the crime has been committed. This includes actions such as hiding evidence or providing assistance to the person who committed the crime. The focus of the definition emphasizes the role of the individual in concealing criminal activity.

The other terms are related but have different meanings in legal context. An accomplice actively participates in the commission of a crime alongside the principal actor, while a conspirator is involved in an agreement to commit a crime, even if the crime has not been carried out. The term "Concealer" is not a recognized legal term within the penal code and does not accurately describe the role of a person involved in criminal activities.
