What is the legal test for overturning a finding of insufficient evidence in a special circumstance case?

to determine the credibility of a witness and the truth or falsity of the facts upon which a determination depends. [Citation.] We resolve neither credibility issues nor evidentiary conflicts; we look for substantial evidence. [Citation.]' [Citation.] A reversal for insufficient evidence 'is unwarranted unless it appears "that upon no hypothesis whatever is there sufficient substantial evidence to support" ' the jury's verdict. [Citation.]" (People v. Zamudio (2008) 43 Cal.4th 327, 357.)

"The same standard applies when the conviction rests primarily on circumstantial evidence. [Citation.] 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.]" (People v. Kraft, supra, 43 Cal.4th at pp. 1053-1054.) We "must accept logical inferences that the jury might have drawn from the circumstantial evidence. [Citation.]" (People v. Maury (2003) 30 Cal.4th 342, 396.) "Where the circumstances reasonably justify the trier of fact's findings, a reviewing court's conclusion the circumstances might also reasonably be reconciled with a contrary finding does not warrant the judgment's reversal. [Citation.]" (People v. Zamudio, supra, 43 Cal.4th at p. 358.)

The same substantial evidence standards apply to true findings on a special circumstance allegation. (People v. Houston (2012) 54 Cal.4th 1186, 1215.)¹³
