What evidence exists that a conspiracy existed between the codefendants in the possession of a kilogram of cocaine?

After reviewing the entire record, we are satisfied that there was sufficient evidence to permit a rational factfinder to conclude that a conspiracy existed between the codefendants. In particular, there was uncontroverted evidence that the kilogram of cocaine came from the purse of Valencia-Alvarez. Such circumstantial evidence, showing that codefendants acted together for a common illegal goal, is sufficient to prove the existence of a conspiracy. See United States v. Penagos, 823 F.2d 346, 348 (9th Cir.1987). ¹
