Is there a single conspiracy as charged in the indictment or multiple conspiracies?

United States v. Huezo, 546 F.3d at 180; see, e.g., Blumenthal v. United States, 332 U.S. 539, 557, 68 S.Ct. 248, 92 L.Ed. 154 (1947) ("[T]he law rightly gives room for allowing the conviction of those discovered upon showing sufficiently the essential nature of the plan and their connections with it, without requiring evidence of knowledge of all its details or of the participation of others.").

The matter of whether there existed a single conspiracy as charged in the indictment or multiple conspiracies "is a question of fact for a properly instructed jury." United States v. Berger, 224 F.3d 107, 114 (2d Cir.2000) (internal quotation marks omitted).
