What is the test for establishing that the evidence was insufficient to convict a defendant?

Appellant also claims the evidence was insufficient to sustain his conviction. ¹ "In reviewing the sufficiency of the evidence, we determine whether any rational trier of fact could have found all the essential elements of the crime beyond a reasonable doubt. The test is whether the evidence and all reasonable inferences which may be drawn from it, when viewed in the light most favorable to the government, sustain the verdict." United States v. Terry, 911 F.2d 272, 278 (9th Cir.1990) (citation omitted).
