CREDIBILITY OF WITNESSES
It is your responsibility to determine the credibility of each witness and the weight to be given the testimony of each witness. In determining such weight or credibility, you may properly consider: the interest, if any, which the witness may have in the result of the trial; the relation of the witness to the parties; the bias or prejudice of the witness, if any has been apparent; the candor, fairness, intelligence, and demeanor of the witness; the ability of the witness to remember and relate past occurrences, the means of observation, and the opportunity of knowing the matters about which the witness has testified. From all the facts and circumstances appearing in evidence and coming to your observation during the trial, aided by the knowledge which you each possess in common with other persons, you will reach your conclusions. You should not let sympathy, sentiment or prejudice enter into your deliberations, but should discharge your duties as jurors impartially, conscientiously, and faithfully under your oaths and return such verdict as the evidence warrants when measured by these instructions.
