Under Oregon law, 162.325 HINDERING PROSECUTION,

A person commits the crime of hindering prosecution if, with intent to hinder the apprehension, prosecution, conviction or punishment of a person who has committed a crime punishable as a felony, or with the intent to assist a person who has committed a crime punishable as a felony in profiting or benefiting from the commission of the crime, the person:

(a) Harbors or conceals such person; or

(b) Warns such person of impending discovery or apprehension; or

(c) Provides or aids in providing such person with money, transportation, weapon, disguise or other means of avoiding discovery or apprehension; or

(d) Prevents or obstructs, by means of force, intimidation or deception, anyone from performing an act which might aid in the discovery or apprehension of such person; or

(e) Suppresses by any act of concealment, alteration or destruction physical evidence which might aid in the discovery or apprehension of such person; or

(f) Aids such person in securing or protecting the proceeds of the crime.

Interestingly, denying knowledge of a person’s location is not ‘concealing’ the person for purposes of hindering prosecution. State v. Carpenter, 365 Or 488 (2019).
