What is the applicable standard of review to determine whether sufficient evidence supports the findings of a juvenile court?

The applicable standard of review to determine whether sufficient evidence supports the juvenile court's findings is well settled. "In reviewing a challenge to the sufficiency of the evidence, we do not determine the facts ourselves. Rather, we 'examine the whole record in the light most favorable to the judgment to determine whether it discloses substantial evidence--evidence that is reasonable, credible and of solid value--such that a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.' [Citations.] We presume 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 cases in which the prosecution relies primarily on circumstantial evidence." (People v. Guerra (2006) 37 Cal.4th 1067, 1129; see also People v. Meza (1995) 38 Cal.App.4th 1741, 1745.)
