Wisconsin reckless homicide is a felony that punishes causing someone’s death through conduct the defendant knew was dangerous, without requiring any intent to kill. The charge splits into two degrees: first-degree, a Class B felony carrying up to 60 years in prison, and second-degree, a Class D felony carrying up to 25 years and a fine of up to $100,000. These cases usually come out of high-speed driving, mishandled firearms, or drug sales that end in a fatal overdose.
First-Degree vs. Second-Degree
The dividing line is a single phrase in the statute: “utter disregard for human life.” First-degree reckless homicide under Wisconsin Statute 940.02 requires the state to prove the defendant recklessly caused death under circumstances showing complete indifference to whether anyone survived.1Wisconsin State Legislature. Wisconsin Statutes 940.02 – First-Degree Reckless Homicide Second-degree reckless homicide under Statute 940.06 covers deaths caused by reckless conduct that falls short of that total indifference. Still dangerous, still criminal, but not at the level of someone who simply didn’t care whether people lived or died.2Wisconsin State Legislature. Wisconsin Code 940.06 – Second-Degree Reckless Homicide
Courts look at the whole picture of what the defendant did and did not do. A last-second swerve or a half-hearted attempt to avoid harm does not necessarily pull a case out of first-degree territory if the conduct that created the danger showed indifference in the first place. The Wisconsin Court of Appeals took that approach in State v. Geske, upholding two counts of first-degree reckless homicide against a driver who ran a red light at roughly 80 to 87 miles per hour.3Wisconsin Court System. State v. Geske, 2012 WI App 15
Drug Delivery Deaths
There is also a separate route to a first-degree charge that does not require proving utter disregard at all. Under Statute 940.02(2), anyone who manufactures, distributes, or delivers a Schedule I or II controlled substance, an analog, ketamine, or flunitrazepam faces a Class B felony if a person dies from using that substance.1Wisconsin State Legislature. Wisconsin Statutes 940.02 – First-Degree Reckless Homicide It does not matter whether the user took the drug alone or mixed it with something else, and the statute reaches every person in the distribution chain, not just the last hand that passed it to the victim. Fentanyl overdose prosecutions commonly rely on this provision.
What “Reckless” Means Under Wisconsin Law
Recklessness is not carelessness. Statute 939.24 defines criminal recklessness as conduct that creates an unreasonable and substantial risk of death or great bodily harm, where the defendant was actually aware of that risk.4Wisconsin State Legislature. Wisconsin Code 939.24 – Criminal Recklessness The word doing the work is “aware.” Negligence means someone should have known. Recklessness means they did know, and went ahead anyway. The Wisconsin Supreme Court confirmed in State v. Burris that reckless homicide does not require intent to kill, but does require proof the defendant consciously created a substantial risk of death.5Wisconsin State Law Library. WIS JI-Criminal 1017
Prosecutors prove that awareness with a mix of direct and circumstantial evidence: witness accounts, surveillance footage, phone records, forensic analysis, and prior warnings or history that show the defendant understood the risk. In an impaired-driving case, that often includes prior OWI convictions or a high blood alcohol reading. In a drug case, lab work ties the substance the defendant distributed to what was in the victim’s body.
Prison Time and Bifurcated Sentencing
The gap between the two degrees is large:
- First-degree reckless homicide, a Class B felony, carries up to 60 years in prison with no statutory fine.6Wisconsin State Legislature. Wisconsin Code 939.50 – Classification of Felonies
- Second-degree reckless homicide, a Class D felony, carries up to 25 years in prison and a fine of up to $100,000.6Wisconsin State Legislature. Wisconsin Code 939.50 – Classification of Felonies
Wisconsin does not use traditional parole for felonies committed on or after December 31, 1999. Under the state’s Truth in Sentencing law, every felony sentence is bifurcated into two parts: a term of initial confinement in prison, followed by a term of extended supervision in the community. The judge sets both at sentencing.7Wisconsin State Legislature. Wisconsin Statutes 973.01 – Bifurcated Sentence of Imprisonment and Extended Supervision The confinement portion cannot be shortened for good behavior, and the defendant is not eligible for parole.8Wisconsin State Legislature. 1997 Wisconsin Act 283
Within the statutory maximum, judges weigh the severity of the conduct, the defendant’s record, the impact on the victim’s family, and any mitigating factors like cooperation or remorse. A second-degree conviction might result in, say, 10 years of confinement followed by 8 years of extended supervision, or a different split entirely.
Enhancers That Push the Maximum Higher
Two enhancers come up often in reckless homicide cases.
The dangerous weapon enhancer under Statute 939.63 adds up to five years to the maximum prison term when the defendant committed the crime while possessing, using, or threatening to use a dangerous weapon, provided the weapon is not itself an element of the underlying offense.9Wisconsin State Legislature. Wisconsin Statutes 939.63 – Penalties Use of a Dangerous Weapon Because reckless homicide can be committed in many ways that do not involve a weapon, the enhancer is available when one happens to be present.
The habitual criminality enhancer under Statute 939.62 targets repeat offenders. If the defendant was convicted of a felony within the five years before the current offense, the maximum for a felony carrying more than 10 years can go up by six additional years. Time spent in prison during that lookback window does not count against it.10Wisconsin State Legislature. Wisconsin Statutes 939.62 – Increased Penalty for Habitual Criminality Both enhancers can apply in the same case, so a first-degree reckless homicide committed with a weapon by a repeat offender could carry a theoretical maximum of 71 years.
Related Homicide Charges
Reckless homicide sits next to several related charges, and plea negotiations often involve moving from one to another.
Homicide by intoxicated use of a vehicle or firearm under Statute 940.09 covers deaths caused while operating a vehicle or firearm under the influence. A first offense is a Class D felony with a 25-year maximum; a defendant with prior OWI-related convictions faces a Class C felony with a 40-year maximum. The statute sets a five-year minimum of confinement unless the court finds a compelling reason to go lower.11Wisconsin State Legislature. Wisconsin Statutes 940.09 – Homicide by Intoxicated Use of Vehicle or Firearm Prosecutors sometimes charge both reckless homicide and intoxicated homicide from a single incident.
Homicide by negligent operation of a vehicle under Statute 940.10 is a Class G felony carrying up to 10 years in prison and a fine of up to $25,000.12Wisconsin State Legislature. Wisconsin Code 940.10 – Homicide by Negligent Operation of Vehicle This charge needs only criminal negligence, meaning the defendant should have been aware of the risk, rather than the actual awareness required for recklessness. It applies only to vehicle-related deaths. Reducing a second-degree reckless homicide down to this charge in a plea negotiation can mean the difference between a 25-year maximum and a 10-year maximum, when a vehicle was involved.
Defenses
Attacking the Mental State
Because criminal recklessness requires conscious awareness of the risk, the most direct defense is that the defendant did not know their conduct was dangerous. An unforeseen mechanical failure, a reasonable precaution that happened to fail, or a hazard the defendant had no reason to anticipate can all cut against the awareness requirement. The distinction between knew-and-ignored and didn’t-realize is often where the case is decided.
Attacking Causation
The state must show the defendant’s reckless conduct was a “substantial factor” in causing the death.5Wisconsin State Law Library. WIS JI-Criminal 1017 A causation defense argues something else was the actual cause: an independent medical complication, intervening treatment, or the victim’s own conduct. The prosecution does not have to prove the defendant was the sole cause, but it does have to show the death would not have happened without them.
Self-Defense
Statute 939.48 permits the use of force to prevent what the person reasonably believes is unlawful interference, including deadly force when they reasonably believe it necessary to prevent imminent death or great bodily harm. Wisconsin’s Castle Doctrine presumes that belief was reasonable when someone unlawfully and forcibly enters a home, vehicle, or place of business while the occupant is inside, and bars the court from considering whether retreat was possible in those settings.13Wisconsin State Legislature. Wisconsin Statutes 939.48 – Self-Defense and Defense of Others
Suppressing Evidence
Evidence obtained through an unconstitutional search or seizure can be excluded, along with further evidence that flowed from it. In reckless homicide cases, that often means firearms, drugs, phone data, or toxicology results. Courts recognize exceptions for evidence from an independent source, evidence police would inevitably have found lawfully, and evidence collected in good-faith reliance on a warrant later found defective.
Consequences That Outlast the Sentence
Prison is not the whole cost of a conviction. Both degrees are felonies, and felony status carries consequences that continue after release.
- Federal law permanently prohibits anyone convicted of a crime punishable by more than one year of imprisonment from possessing firearms or ammunition. Both degrees of reckless homicide clear that threshold by a wide margin, and violating the ban is itself a federal felony.14Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts
- Wisconsin strips voting rights from anyone currently serving a felony sentence, including extended supervision. Rights are restored automatically once the full sentence is completed, not before.
- Employers and landlords in Wisconsin can consider felony convictions, and many professional licenses require a clean record or additional review for felony applicants.
- Courts can order restitution to the victim’s family for funeral costs, counseling, and other losses connected to the death. That obligation survives incarceration.
Extended supervision also comes with its own conditions: regular reporting to a supervision agent, travel restrictions, and the risk of revocation back to prison for violations. The sentence completion date on paper is not the same as the end of the conviction’s reach.
