What is the legal test for a finding of guilt beyond a reasonable doubt?

Further, we review "the evidence in the light most favorable to the prosecution, [asking whether] any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.

Once a defendant [here, minor] has been found guilty of the crime charged, the factfinder's role as weigher of the evidence is preserved through a legal conclusion that upon judicial review all of the evidence is to be considered in the light most favorable to the prosecution."
