What is the standard of review for a special circumstance finding?

^3. " 'When considering a challenge to the sufficiency of the evidence to support a conviction, we review the entire record in the light most favorable to the judgment to determine whether it contains substantial evidencethat is, evidence that is reasonable, credible, and of solid valuefrom which a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.' [Citation.] In so doing, a reviewing court, 'presumes in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence.' [Citation.] The same standard of review applies to the sufficiency of the evidence supporting special circumstance findings." (People v. Powell (2018) 5 Cal.5th 921, 944.)
