What is the test for determining whether a defendant is guilty beyond a reasonable doubt?

defendant guilty beyond a reasonable doubt. [Citation.] Our review is the same in a prosecution primarily resting upon circumstantial evidence. [Citation.] We do not reweigh the evidence or the credibility of witnesses. [Citation.] We must accept logical inferences that the jury might have drawn from the evidence although we would have concluded otherwise. [Citation.] 'If the circumstances reasonably justify the trier of fact's findings, reversal of the judgment is not warranted simply because the circumstances might also reasonably be reconciled with a contrary finding.' [Citation.]" (People v. Ogg (2013) 219 Cal.App.4th 173, 180.)
