What is the test for a challenge to the sufficiency of evidence in a sexual assault case?

Challenges to sufficiency of the evidence are reviewed de novo and will be rejected if, "viewing all the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt." United States v. Jones, 393 F.3d 107, 111 (2d Cir. 2004) (internal quotation marks omitted). The evidence must be viewed in its totality, and circumstantial evidence alone may be sufficient to establish guilt beyond a reasonable doubt. United States v. Glenn, 312 F.3d 58, 63-64 (2d Cir. 2002). We "defer to a jury's assessments with respect to credibility, conflicting testimony, and the jury's choice of the competing inferences that can be drawn from the evidence, [but] specious inferences are not indulged." Jones, 393 F.3d at 111 (internal quotation marks and citation omitted).
