939.24
Criminal recklessness.
(1)
In this section, “criminal recklessness" means that the actor creates an unreasonable and substantial risk of death or great bodily harm to another human being and the actor is aware of that risk, except that for purposes of ss. 940.02 (1m), 940.06 (2) and 940.23 (1) (b) and (2) (b), “criminal recklessness" means that the actor creates an unreasonable and substantial risk of death or great bodily harm to an unborn child, to the woman who is pregnant with that unborn child or to another and the actor is aware of that risk.
(2)
Except as provided in ss. 940.285, 940.29, 940.295, and 943.76, if criminal recklessness is an element of a crime in chs. 939 to 951, the recklessness is indicated by the term “reckless" or “recklessly".
History:  1987 a. 399; 1989 a. 56 s. 259; 1993 a. 445; 1997 a. 295; 2001 a. 109; 2013 a. 307.
Judicial Council Note, 1988: This section is new. It provides a uniform definition of criminal recklessness, the culpable mental state of numerous offenses. Recklessness requires both the creation of an objectively unreasonable and substantial risk of human death or great bodily harm and the actor's subjective awareness of that risk.
Sub. (3) continues the present rule that a voluntarily produced intoxicated or drugged condition is not a defense to liability for criminal recklessness. Ameen v. State, 51 Wis. 2d 175, 185 (1971). Patterned on s. 2.08 of the model penal code, it premises liability on whether the actor would have been aware if not in such condition of the risk of death or great bodily harm. The commentaries to s. 2.08, model penal code, state the rationale of this rule in extended fashion. [Bill 191-S]
There is no crime of “attempted homicide by reckless conduct" since the completed offense does not require intent while any attempt must demonstrate intent. State v. Melvin, 49 Wis. 2d 246, 181 N.W.2d 490 (1970).
Felony murder is committed when the death of another person is caused by a defendant during the commission of certain crimes, including burglary. The elements of burglary include the intent to either steal or to commit a felony. The evidence demonstrated that the defendant in this case forced his way into a building and started shooting with two guns, which was indicative of an intent to recklessly endanger the safety of those inside—a felony. Therefore, the defendant was convicted of a valid crime. State v. Mays, 2022 WI App 24, 402 Wis. 2d 162, 975 N.W.2d 649, 21-0765.
With respect to first-degree reckless injury under s. 940.23 (1) (a), a successful assertion of self-defense under s. 939.48 (1) negates an element of the crime, rendering self-defense a negative defense rather than an affirmative defense. Because, under sub. (1), the “criminally reckless conduct" element of reckless injury requires proof that the defendant has created an “unreasonable" and substantial risk of death or great bodily harm to another person, proof that the defendant reasonably believed that the other person posed a risk of death or great bodily harm to himself and that the use of force was necessary to eliminate that risk will necessarily preclude a finding that the defendant's use of force was unreasonable and criminally reckless. Once a defendant establishes the existence of a statutory affirmative defense, Wisconsin law imposes on the state the burden of disproving the defense beyond a reasonable doubt. Brown v. Eplett, 48 F.4th 543 (2022).
