Okla. Stat. tit. 21, § 21-173: Accessories defined

All persons who, after the commission of any felony, conceal or

aid the offender, with knowledge that he or she has committed a

felony, and with intent that the person may avoid or escape from

arrest, trial, conviction, or punishment, are accessories. In the

case of murder, a person is accountable under this statute for

accessory to murder if the person knew or reasonably should have

known that the conduct committed upon the victim could foreseeably

result in the death of the victim.
