State v. Allbaugh
State v. Allbaugh, 148 Wis. 2d 807, 814, 436 N.W.2d 898 (Ct. App. 1989) is instructive on the kinds of circumstances that tend to show knowledge sufficient to constitute drugs possession.
In Allbaugh, the Court explained that:
Among the "incriminating" facts which can "buttress" the inference of knowing possession from joint occupancy of premises in which the drugs are found are:
(1) the defendant's "access to ... areas in which drugs are found;"
(2) whether the drugs are in plain view;
(3) the presence of items used in the manufacture or packaging of drugs.
