What is the test for acquitting a defendant if the jury finds that circumstantial evidence is susceptible to two interpretations?

" 'Although it is the duty of the jury to acquit a defendant if it finds that circumstantial evidence is susceptible of two interpretations, one of which suggests guilt and the other innocence, it is the jury, not the appellate court which must be convinced of the defendant's guilt beyond a reasonable doubt. If the circumstances reasonably justify the trier of fact's findings, the opinion of the reviewing court that the circumstances might also be reasonably reconciled with a contrary finding does not warrant a reversal of the judgment.' " (People v. Perez (1992) 2 Cal.4th 1117, 1124.)
