To prove a specific crime occurred, the State of Wisconsin must prove all “elements of the crime” beyond a reasonable doubt. For instance, to prove a Carrying a Concealed Weapon offense, the State must show three elements: 1. The defendant went armed with a dangerous weapon; 2. The defendant was aware of the presence of the weapon; 3. The weapon was concealed.
Each crime has different elements. Below is a link to a PDF that lists the elements for the most common criminal offense charged in Wisconsin.
