940.01(2)(a)(a) Adequate provocation. Death was caused under the influence of adequate provocation as defined in s. 939.44. 940.01(2)(b)(b) Unnecessary defensive force. Death was caused because the actor believed he or she or another was in imminent danger of death or great bodily harm and that the force used was necessary to defend the endangered person, if either belief was unreasonable. 940.01(2)(c)(c) Prevention of felony. Death was caused because the actor believed that the force used was necessary in the exercise of the privilege to prevent or terminate the commission of a felony, if that belief was unreasonable. 940.01(3)(3) Burden of proof. When the existence of an affirmative defense under sub. (2) has been placed in issue by the trial evidence, the state must prove beyond a reasonable doubt that the facts constituting the defense did not exist in order to sustain a finding of guilt under sub. (1). 940.01 HistoryHistory: 1987 a. 399; 1997 a. 295. 940.01 NoteJudicial Council Note, 1988: First-degree intentional homicide is analogous to the prior offense of first-degree murder. Sub. (2) formerly contained a narrower definition of “intent to kill” than the general definition of criminal intent. That narrower definition has been eliminated in the interest of uniformity. Section 939.23 now defines the intent referred to.
940.01 NoteThe affirmative defenses specified in sub. (2) were formerly treated in s. 940.05. This caused confusion because they seemed to be elements of manslaughter rather than defenses to first-degree murder. Sub. (2) specifies only those affirmative defenses which mitigate an intentional homicide from first to 2nd degree. Other affirmative defenses are a defense to 2nd-degree intentional homicide also, such as self-defense, i.e., when both beliefs specified in sub. (2) (b) are reasonable. Section 939.48.
940.01 AnnotationThe prosecution is required to prove only that the defendant’s acts were a substantial factor in the victim’s death; not the sole cause. State v. Block, 170 Wis. 2d 676, 489 N.W.2d 715 (Ct. App. 1992). 940.01 AnnotationThe trial court must apply an objective reasonable view of the evidence test to determine whether under sub. (3) a mitigating affirmative defense “has been placed in issue” before submitting the issue to the jury. Shawn B.N. v. State, 173 Wis. 2d 343, 497 N.W.2d 141 (Ct. App. 1992). 940.01 AnnotationImperfect self-defense contains an initial threshold element requiring a reasonable belief that the defendant was terminating an unlawful interference with the defendant’s person. State v. Camacho, 176 Wis. 2d 860, 501 N.W.2d 380 (1993). 940.01 AnnotationSub. (1) (a) cannot be applied against a mother for actions taken against a fetus while pregnant as the applicable definition of human being under s. 939.22 (16) is limited to one who is born alive. Sub. (1) (b) does not apply because s. 939.75 (2) (b) excludes from its application actions by a pregnant woman. State v. Deborah J.Z., 228 Wis. 2d 468, 596 N.W.2d 490 (Ct. App. 1999), 96-2797. 940.01 AnnotationA defendant seeking a jury instruction on perfect self-defense to a charge of first-degree intentional homicide must satisfy an objective threshold showing that the defendant reasonably believed that the defendant was preventing or terminating an unlawful interference with the defendant’s person and reasonably believed that the force used was necessary to prevent imminent death or great bodily harm. A defendant seeking a jury instruction on unnecessary defensive force under sub. (2) (b) to a charge of first-degree intentional homicide is not required to satisfy the objective threshold. State v. Head, 2002 WI 99, 255 Wis. 2d 194, 648 N.W.2d 413, 99-3071. 940.01 AnnotationA defendant who claims self-defense to a charge of first-degree intentional homicide may use evidence of a victim’s violent character and past acts of violence to show a satisfactory factual basis that the defendant actually believed the defendant was in imminent danger of death or great bodily harm and actually believed that the force used was necessary to defend himself or herself, even if both beliefs were unreasonable. State v. Head, 2002 WI 99, 255 Wis. 2d 194, 648 N.W.2d 413, 99-3071. 940.01 AnnotationA privilege for excusable homicide by accident or misfortune is incorporated in s. 939.45 (6). Accident is a defense that negatives intent. If a person kills another by accident, the killing could not have been intentional. Accident must be disproved beyond a reasonable doubt when a defendant raises it as a defense. When the state proves intent to kill beyond a reasonable doubt, it necessarily disproves accident. State v. Watkins, 2002 WI 101, 255 Wis. 2d 265, 647 N.W.2d 244, 00-0064. 940.01 AnnotationA defendant may demonstrate that the defendant was acting lawfully, a necessary element of an accident defense, by showing that the defendant was acting in lawful self-defense. Although intentionally pointing a firearm at another constitutes a violation of s. 941.20, under s. 939.48 (1) a person is privileged to point a gun at another person in self-defense if the person reasonably believes that the threat of force is necessary to prevent or terminate what the person reasonably believes to be an unlawful interference. State v. Watkins, 2002 WI 101, 255 Wis. 2d 265, 647 N.W.2d 244, 00-0064. 940.01 AnnotationThe common law “year-and-a-day rule” that no homicide is committed unless the victim dies within a year and a day after the injury is inflicted is abrogated, with prospective application only.

A substantial factor need not be the sole cause of death for one to be held legally culpable. Whether an intervening act was negligent, intentional, or legally wrongful is irrelevant. The state must still prove beyond a reasonable doubt that the defendant’s acts were a substantial factor in producing the death. State v.

940.02940.02 First-degree reckless homicide. 940.02(1)(1) Whoever recklessly causes the death of another human being under circumstances which show utter disregard for human life is guilty of a Class B felony. 940.02(1m)(1m) Whoever recklessly causes the death of an unborn child under circumstances that show utter disregard for the life of that unborn child, the woman who is pregnant with that unborn child or another is guilty of a Class B felony. 940.02(2)(2) Whoever causes the death of another human being under any of the following circumstances is guilty of a Class B felony: 940.02(2)(a)(a) By manufacture, distribution or delivery, in violation of s. 961.41, of a controlled substance included in schedule I or II under ch. 961, of a controlled substance analog of a controlled substance included in schedule I or II under ch. 961 or of ketamine or flunitrazepam, if another human being uses the controlled substance or controlled substance analog and dies as a result of that use. This paragraph applies: 940.02(2)(a)1.1. Whether the human being dies as a result of using the controlled substance or controlled substance analog by itself or with any compound, mixture, diluent or other substance mixed or combined with the controlled substance or controlled substance analog. 940.02(2)(a)2.2. Whether or not the controlled substance or controlled substance analog is mixed or combined with any compound, mixture, diluent or other substance after the violation of s. 961.41 occurs. 940.02(2)(a)3.3. To any distribution or delivery described in this paragraph, regardless of whether the distribution or delivery is made directly to the human being who dies. If possession of the controlled substance included in schedule I or II under ch. 961, of the controlled substance analog of the controlled substance included in schedule I or II under ch. 961 or of the ketamine or flunitrazepam is transferred more than once prior to the death as described in this paragraph, each person who distributes or delivers the controlled substance or controlled substance analog in violation of s. 961.41 is guilty under this paragraph. 940.02(2)(b)(b) By administering or assisting in administering a controlled substance included in schedule I or II under ch. 961, a controlled substance analog of a controlled substance included in schedule I or II of ch. 961 or ketamine or flunitrazepam, without lawful authority to do so, to another human being and that human being dies as a result of the use of the substance. This paragraph applies whether the human being dies as a result of using the controlled substance or controlled substance analog by itself or with any compound, mixture, diluent or other substance mixed or combined with the controlled substance or controlled substance analog. 940.02 NoteJudicial Council Note, 1988: [As to sub. (1)] First-degree reckless homicide is analogous to the prior offense of 2nd-degree murder. The concept of “conduct evincing a depraved mind, regardless of human life” has been a difficult one for modern juries to comprehend. To avoid the mistaken connotation that a clinical mental disorder is involved, the offense has been recodified as aggravated reckless homicide. The revision clarifies that a subjective mental state, i.e., criminal recklessness, is required for liability. See s. 939.24. The aggravating element, i.e., circumstances which show utter disregard for human life, is intended to codify judicial interpretations of “conduct evincing a depraved mind, regardless of life”. State v. Dolan, 44 Wis. 2d 68 (1969); State v. Weso, 60 Wis. 2d 404 (1973). 940.02 NoteUnder prior law, adequate provocation mitigated 2nd-degree murder to manslaughter. State v. Hoyt, 21 Wis. 2d 284 (1964). Under this revision, the analogs of those crimes, i.e., first-degree reckless and 2nd-degree intentional homicide, carry the same penalty; thus mitigation is impossible. Evidence of provocation will usually be admissible in prosecutions for crimes requiring criminal recklessness, however, as relevant to the reasonableness of the risk (and, in prosecutions under this section, whether the circumstances show utter disregard for human life). Since provocation is integrated into the calculus of recklessness, it is not an affirmative defense thereto and the burdens of production and persuasion stated in s. 940.01 (3) are inapplicable. [Bill 191-S] 940.02 AnnotationPossession of a controlled substance is not a lesser included offense of sub. (2) (a). State v. Clemons, 164 Wis. 2d 506, 476 N.W.2d 283 (Ct. App. 1991). 940.02 AnnotationGenerally expert evidence of personality dysfunction is irrelevant to the issue of intent, although it might be admissible in very limited circumstances. State v. Morgan, 195 Wis. 2d 388, 536 N.W.2d 425 (Ct. App. 1995), 93-2611. 940.02 AnnotationUtter disregard for human life is an objective standard of what a reasonable person in the defendant’s position is presumed to have known and is proved through an examination of the acts that caused death and the totality of the circumstances surrounding the conduct. State v. Edmunds, 229 Wis. 2d 67, 598 N.W.2d 290 (Ct. App. 1999), 98-2171. 940.02 AnnotationThe common law “year-and-a-day rule” that no homicide is committed unless the victim dies within a year and a day after the injury is inflicted is abrogated, with prospective application only. State v. Picotte, 2003 WI 42, 261 Wis. 2d 249, 661 N.W.2d 381, 01-3063. 940.02 AnnotationThe punishments for first-degree reckless homicide by delivery of a controlled substance under sub. (2) (a) and contributing to the delinquency of a child with death as a consequence in violation of s. 948.40 (1) and (4) (a) are not multiplicitous when both convictions arise from the same death. State v. Patterson, 2010 WI 130, 329 Wis. 2d 599, 790 N.W.2d 909, 08-1968. 940.02 AnnotationAn actor causes death if the actor’s conduct is a substantial factor in bringing about that result. A substantial factor need not be the sole cause of death for one to be held legally culpable. Whether an intervening act was negligent, intentional, or legally wrongful is irrelevant. The state must still prove beyond a reasonable doubt that the defendant’s acts were a substantial factor in producing the death. State v. Below, 2011 WI App 64, 333 Wis. 2d 690, 799 N.W.2d 95, 10-0798. 940.02 AnnotationUnder the facts of this case, the court did not err in denying an intervening cause instruction. Even if the defendant could have established that the termination of the victim’s life support was “wrongful” under Wisconsin law, that wrongful act would not break the chain of causation between the defendant’s actions and victim’s subsequent death. State v. Below, 2011 WI App 64, 333 Wis. 2d 690, 799 N.W.2d 95, 10-0798. 940.02 AnnotationWhile swerving has been held to show regard for life, the defendant’s conduct must be considered in light of the totality of the circumstances. When the defendant was driving over 80 miles per hour on a major, well-traveled city street after consuming alcohol and prescription pills and never braked or slowed down before running a red light, an ineffectual swerve failed to demonstrate a regard for human life. State v. Geske, 2012 WI App 15, 339 Wis. 2d 170, 810 N.W.2d 226, 10-2808. 940.02 AnnotationUtter disregard for human life is interpreted consistently with previous interpretations of the “depraved mind” element that it replaced. State v. Johnson, 2021 WI 61, 397 Wis. 2d 633, 961 N.W.2d 18, 18-2318. 940.02 AnnotationThe only difference between first-degree and second-degree reckless homicide is that “utter disregard for human life” is a required element for first-degree, but not second-degree, reckless homicide. In this case, there was evidence that the defendant acted in fear for his own life, not necessarily with utter disregard for the victim’s life. Based on that evidence, the circuit court should have instructed the jury on the lesser-included offense of second-degree reckless homicide as well as first-degree reckless homicide. State v. Johnson, 2021 WI 61, 397 Wis. 2d 633, 961 N.W.2d 18, 18-2318. 940.02 AnnotationUnder sub. (2) (a), Wisconsin’s “Len Bias” law, a “delivery” occurs when a controlled substance is transferred from one person to another. In this case, the defendant aided and abetted the seller’s delivery of a fatal amount of heroin to the defendant’s daughter by driving her to meet the seller so that the delivery could take place. The defendant assisted both the seller’s delivery of heroin and the defendant’s daughter’s acquisition of it. That the defendant did not communicate directly with the seller, and may have wanted to obtain some of the drugs for the defendant’s own use, did not change the fact that the defendant’s conduct assisted the seller in delivering the drugs to the defendant’s daughter.

940.03940.03 Felony murder. Whoever causes the death of another human being while committing or attempting to commit a crime specified in s. 940.19, 940.195, 940.20, 940.201, 940.203, 940.204, 940.225 (1) or (2) (a), 940.30, 940.31, 943.02, 943.10 (2), 943.231 (1), or 943.32 (2) may be imprisoned for not more than 15 years in excess of the maximum term of imprisonment provided by law for that crime or attempt. 940.03 NoteJudicial Council Note, 1988: The prior felony murder statute (s. 940.02 (2)) did not allow enhanced punishment for homicides caused in the commission of a Class B felony. State v. Gordon, 111 Wis. 2d 133, 330 N.W.2d 564 (1983). The revised statute eliminates the “natural and probable consequence” limitation and limits the offense to homicides caused in the commission of or attempt to commit armed robbery, armed burglary, arson, first-degree sexual assault or 2nd-degree sexual assault by use or threat of force or violence. The revised penalty clause allows imposition of up to 20 years’ imprisonment more than that prescribed for the underlying felony. Prosecution and punishment for both offenses remain barred by double jeopardy. State v. Carlson, 5 Wis. 2d 595, 93 N.W.2d 355 (1958). [Bill 191-S] 940.03 AnnotationTo prove that the defendant caused the death, the state need only prove that the defendant’s conduct was a substantial factor. The phrase “while committing or attempting to commit” encompasses the immediate flight from the felony. A defendant may be convicted if another person, including an intended felony victim, fires the fatal shot. State v. Oimen, 184 Wis. 2d 423, 516 N.W.2d 399 (1994). See also State v. Rivera, 184 Wis. 2d 485, 516 N.W.2d 391 (1994); State v. Chambers, 183 Wis. 2d 316, 515 N.W.2d 531 (Ct. App. 1994). 940.03 AnnotationAttempted felony murder does not exist. Attempt requires intent, and the crime of felony murder is complete without specific intent. State v. Briggs, 218 Wis. 2d 61, 579 N.W.2d 783 (Ct.

State v. Below, 2011 WI App 64, 333 Wis. 2d 690, 799 N.W.2d 95, 10-0798. 940.03 AnnotationFelony 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. 940.04(1)(1) Any person, other than the mother, who intentionally destroys the life of an unborn child is guilty of a Class H felony. 940.04(2)(2) Any person, other than the mother, who does either of the following is guilty of a Class E felony: 940.04(2)(a)(a) Intentionally destroys the life of an unborn quick child; or 940.04(2)(b)(b) Causes the death of the mother by an act done with intent to destroy the life of an unborn child. It is unnecessary to prove that the fetus was alive when the act so causing the mother’s death was committed. 940.04(5)(5) This section does not apply to a therapeutic abortion which: 940.04(5)(b)(b) Is necessary, or is advised by 2 other physicians as necessary, to save the life of the mother; and 940.04(5)(c)(c) Unless an emergency prevents, is performed in a licensed maternity hospital. 940.04(6)(6) In this section “unborn child” means a human being from the time of conception until it is born alive. 940.04 HistoryHistory: 2001 a. 109; 2011 a. 217. 940.04 AnnotationAborting a child against a father’s wishes does not constitute intentional infliction of emotional distress.

Therefore, a rational-basis review is the appropriate standard for a constitutional challenge to abortion laws.
