What is the standard of review for the sufficiency of the evidence to support a conviction?

In reviewing verdicts for the sufficiency of the evidence to support them, the standard of review is whether there was substantial evidence of proof beyond a reasonable doubt of each essential element to support the conviction. United States v. Douglass, 780 F.2d 1472, 1476 (9th Cir.1986). The court must view the evidence in the light most favorable to the government and the reviewing court must respect the province of the jury to ascertain the credibility of witnesses, resolve evidentiary conflicts, and draw reasonable inferences from proven facts, assuming the jury resolved these matters in a manner that supports the verdict. United States v. Goode, 814 F.2d 1353, 1355 (9th Cir.1987).
