If a person who could have been a witness at the trial is not called to testify, you may be able to infer that the person’s testimony would have been unfavorable to a party in the case. You may draw this inference only if you find that:
(1) The witness is within the control of, or peculiarly available to, that party;
(2) The issue on which the person could have testified is an issue of fundamental importance, rather than one that is trivial or insignificant;
(3) As a matter of reasonable probability, it appears naturally in the interest of that party to call the person as a witness;
(4) There is no satisfactory explanation of why the party did not call the person as a witness; and
(5) The inference is reasonable in light of all the circumstances.
The parties in this case are the [State of Washington] [County of ] [City of ] and(name of defendant).
