State v. Diaz (1990)
In State v. Diaz, 166 Ariz. 442, 803 P.2d 435 (App. 1990), vacated in part on other grounds, 168 Ariz. 363, 813 P.2d 728 (1991) the defendant admitted transporting an illegal substance but claimed ignorance of the specific type of substance he had transported. Id. at 444, 803 P.2d at 437.
In Diaz, the Court commented that the requisite knowledge can be proved by showing that a defendant "was aware of the high probability that the packages contained the narcotic drug the defendant was charged with transporting and that he acted with a conscious purpose to avoid learning the true contents of the packages." Id. at 445, 803 P.2d at 438.
