First-Degree Reckless Homicide Defense (Wis. Stat. § 940.02) | Cafferty & Scheidegger

“Negligent Homicide” Is Not the Term in Wisconsin

In common conversation, people describe a death caused by carelessness as “negligent homicide” or “involuntary manslaughter.” Wisconsin uses neither term. The functional equivalent in this state is first-degree reckless homicide under Wis. Stat. § 940.02. It covers killings caused by recklessness that shows utter disregard for human life, drug-delivery deaths, certain shooting-into-a-crowd cases, and many vehicular fatalities outside the OWI statute.

What the State Must Prove

• The defendant caused the death of another human being.
• The act showed utter disregard for human life, more than ordinary negligence, more than criminal recklessness, a category higher.
• For the drug-delivery subcategory, the defendant delivered the controlled substance (or a controlled-substance analog) and that substance was a substantial factor in the victim’s death.

“Utter disregard” is a culpability standard above simple recklessness. Wisconsin appellate courts analyze the defendant’s conduct before, during, and after the act to determine whether it crossed that line. A defendant who immediately called 911 and rendered aid, for example, has substantially more room to argue against utter disregard than one who fled.

The Drug-Delivery Variant

Overdose deaths in Wisconsin are increasingly charged under § 940.02(2). Fentanyl has accelerated the pattern. A defendant who sold, shared, or even jointly purchased a controlled substance that another person later used and died from can be charged with a Class B felony, even when the sale was among friends and no profit was involved.

Defenses specific to drug-delivery charges:

• Substantial-factor causation. If the victim had other drugs or medical factors contributing to death, expert toxicology can undercut “substantial factor.”
• Delivery element. Sharing from a common supply is legally distinct from delivering. Case law is active on this point.
• Chain of custody. The State must tie the specific substance in the victim’s body to the defendant.
• Hearsay and text-message evidence often forms the bulk of drug-delivery cases and is vulnerable to Crawford and Bruton challenges.

Sentencing Reality

First-degree reckless homicide sentencing varies widely. In the 4-county southeast Wisconsin region, judges have imposed everything from probation-eligible short confinement to the full 60 years. The factors that move the needle:

• Whether the drug-delivery subcategory applies.
• Whether the defendant rendered aid or fled.
• Prior felony record.
• Strength of utter-disregard evidence versus ordinary-recklessness evidence.
• Victim impact.

Good sentencing preparation, mitigation witnesses, mental-health or substance-abuse evaluations, written sentencing memoranda, routinely knocks years off the confinement portion of the bifurcated sentence.

Defense Angles

• Mens-rea reduction. If the State cannot prove utter disregard, the charge drops to second-degree reckless homicide under § 940.06, a Class D felony (25-year maximum).
• Causation. Intervening medical treatment, alternative cause of death, and failure to connect the defendant’s act to the death all live here.
• Identity and presence. Often the weakest link in the State’s case in drug-delivery cases.
• Miranda and statement suppression. Nearly every reckless homicide case involves a contested interview.
• Expert forensics. Toxicology, time-of-death, and ballistic reconstructions deserve independent review.

Call Before You Talk to Anyone Else

If you are under investigation for a reckless homicide, particularly a drug-delivery case, the hours after the death are when law enforcement develops the theory. A defense attorney involved early can protect you during interviews, preserve exculpatory evidence, and shape the charging decision.
