What is the state of the law in relation to evidence presented at trial to support the allegation of a conspiracy to manufacture methamphetamine?

The government's proof at trial was not materially at variance with the indictment. The proof established a single conspiracy. The government presented evidence establishing consistent joint activity among Alcala-Ramirez and his codefendants over the time period charged in the indictment. This evidence included purchases of large amounts of methamphetamine precursor chemicals, the establishment of clandestine labs, and a working arrangement among the Alcala-Ramirez group to sell precursor chemicals the group manufactured. This evidence was sufficient for a reasonable juror to find beyond a reasonable doubt that Alcala-Ramirez was involved in a single conspiracy. See United States v. Ross, 123 F.3d 1181, 1184 (9th Cir.1997), cert. denied, --- U.S. ----, 118 S.Ct. 733, 139 L.Ed.2d 670 (1998).
