The district court prepared its instruction by following two unpublished opinions in which this court distinguished permissive-inference instructions from the instructions given in Olson and LaBatte. See State v. Otterson, No. C1–00–1419, 2001 WL 410282 at *2 (Minn.App. Apr. 24, 2001); State v. Acosta, No. C3–99–1785, 2000 WL 1146120 at *3 (Minn.App. Aug. 15, 2000).
