What is the standard for determining a defendant's guilt beyond a reasonable doubt?

crime beyond a reasonable doubt." [Citations.] We examine the record to determine "whether it shows evidence that is reasonable, credible and of solid value from which a rational trier of fact could find the defendant guilty . . . ." [Citation.] Further, "the appellate court presumes in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence." [Citation.] This standard applies whether direct or circumstantial evidence is involved. "Although it is the jury's duty to acquit a defendant if it finds the circumstantial evidence susceptible of two reasonable interpretations, one of which suggests guilt and the other innocence, it is the jury, not the appellate court that must be convinced of the defendant's guilt beyond a reasonable doubt. [Citation.] '"If the circumstances reasonably justify the trier of fact's findings, the opinion of the reviewing court that the circumstances might also reasonably be reconciled with a contrary finding does not warrant a reversal of the judgment."'"
