Wis. Stat. § 939.63
The fact that the maximum term for a misdemeanor may exceed one year under sub. (1) (a) does not upgrade the crime to felony status. State v. Denter, 121 Wis. 2d 118, 357 N.W.2d 555 (1984). Possession encompasses both actual and constructive possession. To prove a violation of this section, the state must prove that the defendant possessed the weapon to facilitate the predicate offense. State v. Peete, 185 Wis. 2d 255, 517 N.W.2d 149 (1994). See also State v. Howard, 211 Wis. 2d 269, 564 N.W.2d 753 (1997), 95-0770. An automobile may constitute a dangerous weapon under s. 939.22(10). State v. Bidwell, 200 Wis. 2d 200, 546 N.W.2d 507 (Ct. App. 1996). Under Peete, there is sufficient evidence of possession if the evidence allows a reasonable jury to find beyond a reasonable doubt that the defendant possessed a dangerous weapon in order to use it or threaten to use it, even if the defendant did not use or threaten to use it in the commission of the crime. State v. Page, 2000 WI App 267, 240 Wis. 2d 276, 622 N.W.2d 285, 99-2015. When two penalty enhancers are applicable to the same crime, the length of the second penalty enhancer is based on the maximum term for the base crime as extended by the first penalty enhancer. State v. Quiroz, 2002 WI App 52, 251 Wis. 2d 245, 641 N.W.2d 715, 01-1549.
