Indiana Manslaughter Laws: Voluntary, Involuntary and OWI Deaths

Indiana uses the voluntary and involuntary manslaughter labels, but defines them in its own way. Voluntary manslaughter under IC 35-42-1-3 is knowingly or intentionally killing another human being while acting under sudden heat, a Level 2 felony punishable by 10 to 30 years. Involuntary manslaughter under IC 35-42-1-4 is a killing during certain lesser felonies, risky misdemeanors or a battery, and a reckless killing is the separate offense of reckless homicide under IC 35-42-1-5; both are Level 5 felonies punishable by 1 to 6 years.

A death caused by impaired driving is its own Title 9 offense, operating a vehicle while intoxicated causing death or catastrophic injury, a Level 4 felony under IC 9-30-5-5 punishable by 2 to 12 years. For how other states grade these offenses, see our guide to manslaughter laws by state.

Jurisdiction scope: This article covers Indiana criminal statutes on homicide below murder: voluntary manslaughter, involuntary manslaughter and reckless homicide in IC 35-42-1, operating while intoxicated causing death in IC 9-30-5 (which since July 1, 2026 includes operating a watercraft), and the felony sentencing ranges in IC 35-50-2. It does not cover murder (see murder sentencing guidelines), self-defense (see Indiana self-defense laws), civil lawsuits over a death (see Indiana wrongful death), or federal offenses (see the manslaughter laws hub).

What counts as manslaughter in Indiana?

Indiana's homicide chapter, IC 35-42-1, sets out these offenses below murder:

• Voluntary manslaughter (IC 35-42-1-3): a knowing or intentional killing while acting under sudden heat.
• Involuntary manslaughter (IC 35-42-1-4): a killing while committing or attempting certain lesser crimes or a battery.
• Reckless homicide (IC 35-42-1-5): recklessly killing another human being.

Outside that chapter, IC 9-30-5-5 makes causing a death while operating a vehicle while intoxicated a separate felony. The homicide chapter contains sections on murder, dealing in a controlled substance resulting in death, causing suicide, assisting suicide, voluntary manslaughter, involuntary manslaughter, reckless homicide and feticide, and no section on negligent homicide or vehicular homicide. The culpability section, IC 35-41-2-2, defines recklessly but contains no criminal negligence standard.

Indiana manslaughter offenses at a glance

The ranges come from Indiana's felony sentencing chapter: Level 2 under IC 35-50-2-4.5, Level 4 under IC 35-50-2-5.5, and Level 5 under IC 35-50-2-6(b), which applies to crimes committed after June 30, 2014. Each sets a fixed term with an advisory sentence, plus a possible fine of up to $10,000. For more on how Indiana sentences each felony level, see Indiana felony and misdemeanor classes.

Voluntary manslaughter and sudden heat

Section 35-42-1-3 provides:

"(a) A person who knowingly or intentionally: (1) kills another human being; or (2) except as provided in section 6.5 of this chapter, kills a fetus in any stage of development; while acting under sudden heat commits voluntary manslaughter, a Level 2 felony. (b) The existence of sudden heat is a mitigating factor that reduces what otherwise would be murder under section 1(1) of this chapter to voluntary manslaughter."

The offense requires a knowing or intentional killing. Sudden heat is what sets it apart: subsection (b) treats it as a mitigating factor that reduces what would otherwise be murder under section 1(1) to voluntary manslaughter.

The statute does not define sudden heat. In Suprenant v. State, 925 N.E.2d 1280 (Ind. Ct. App. 2010), the Court of Appeals of Indiana described it this way:

"'Sudden heat' is characterized as anger, rage, resentment, or terror sufficient to obscure the reason of an ordinary person, preventing deliberation and premeditation, excluding malice, and rendering a person incapable of cool reflection."

The court added that anger without more is not sufficient to support an instruction on sudden heat, and that words alone do not "constitute sufficient provocation to warrant a jury instruction on voluntary manslaughter." Suprenant was decided under the earlier lettered felony classes; the current statute grades the offense as a Level 2 felony.

Section 35-42-1-3 contains no clause excluding a victim's sexual orientation or gender identity as a source of sudden heat, and none of the three below-murder sections, 35-42-1-3, -4 and -5, mentions an unreasonable belief in the need for self-defense. For the justification rules themselves, see Indiana self-defense laws.

Involuntary manslaughter and reckless homicide

Indiana's two lower homicide offenses turn on different elements.

Involuntary manslaughter under IC 35-42-1-4(b) is built on another crime. It applies when a person "kills another human being while committing or attempting to commit: (1) a Level 5 or Level 6 felony that inherently poses a risk of serious bodily injury; (2) a Class A misdemeanor that inherently poses a risk of serious bodily injury; or (3) battery." Subsection (c) sets out a parallel offense for killing a fetus, and its list of predicate offenses includes operating a vehicle while intoxicated under IC 9-30-5-1 through 9-30-5-5. Both forms are Level 5 felonies.

Reckless homicide is the offense for a reckless killing. Section 35-42-1-5 reads in full: "A person who recklessly kills another human being commits reckless homicide, a Level 5 felony." The culpability statute defines the term:

"A person engages in conduct 'recklessly' if he engages in the conduct in plain, conscious, and unjustifiable disregard of harm that might result and the disregard involves a substantial deviation from acceptable standards of conduct." (IC 35-41-2-2(c))

Under IC 35-41-2-2(d), unless the statute defining the offense provides otherwise, a required kind of culpability applies "with respect to every material element of the prohibited conduct."

Both offenses carry the Level 5 range of 1 to 6 years, with an advisory sentence of 3 years and a possible fine of up to $10,000 (IC 35-50-2-6(b)).

Vehicular and OWI manslaughter in Indiana

Indiana has no offense called vehicular manslaughter or vehicular homicide. A death caused by an impaired driver is charged under the Title 9 offense of operating a vehicle while intoxicated causing death or catastrophic injury. The reckless homicide statute has no vehicle element, so it reaches a reckless killing by any means, including driving.

For the OWI chapter, "vehicle" means "a device for transportation by land, air, or water" (IC 9-13-2-196(d)). P.L.158-2026 (House Enrolled Act 1249), effective July 1, 2026, made watercraft vehicles for the crime of operating while intoxicated and repealed the separate crime of operating a motorboat while intoxicated (IC 35-46-9). Since that date, a death caused by operating a boat or other watercraft while intoxicated falls under the same Level 4 offense in IC 9-30-5-5.

Operating while intoxicated causing death

Section 9-30-5-5(a) provides that a person "who causes the death or catastrophic injury of another person when operating a vehicle" commits a Level 4 felony if the person was operating:

• with an alcohol concentration of at least 0.08 gram of alcohol per 100 milliliters of blood or per 210 liters of breath;
• with a controlled substance listed in schedule I or II of IC 35-48-2, or its metabolite, in the blood; or
• while intoxicated.

A Level 4 felony carries a fixed term of 2 to 12 years, with an advisory sentence of 6 years and a possible fine of up to $10,000 (IC 35-50-2-5.5). Other parts of the statute and related sections add these rules:

• One offense per victim. Under IC 9-30-5-5(c), a person "commits a separate offense for each person or law enforcement animal whose death (or catastrophic injury, in the case of a person) is caused by the violation."
• Prescription defense. For the controlled-substance prong only, IC 9-30-5-5(d) makes it a defense that the person consumed the substance "in accordance with a valid prescription or order of a practitioner" acting in the course of professional practice.
• Later OWI offenses. A later OWI under IC 9-30-5-1 or -2, or under IC 9-30-5-3(a)(2), is a Level 5 felony if the person has a previous conviction of operating while intoxicated causing death or catastrophic injury, or causing serious bodily injury (IC 9-30-5-3(b)).
• Driving privileges. When a person is convicted of an offense that includes the element of causing another person's death and the offense involved operating a motor vehicle, or was an offense under IC 9-30-5, the court must suspend driving privileges for "at least two (2) years and not more than the maximum allowable period of incarceration," and the person is not eligible for specialized driving privileges (IC 9-30-16-2(c)).

The driving-privilege rule also applies to a reckless homicide conviction when the offense involved operating a motor vehicle. For OWI penalties when no one dies, see Indiana DUI laws.

Other driving offenses graded by a death

Several Title 9 offenses that do not require impairment carry a higher grade when someone dies:

• Driving while suspended. Knowingly operating a motor vehicle on a highway while one's driving privileges are suspended or revoked because of a conviction is a Level 5 felony when the operation results in the death or catastrophic injury of another person (IC 9-24-19-3(b)(2)).
• Highway worksites. Reckless operation, aggressive driving, a speed contest, or recklessly failing to obey a traffic control device or flagman in the immediate vicinity of a highway worksite when workers are present is a Level 5 felony when the offense results in the death of a worker in the worksite (IC 9-21-8-56(h)).
• Stationary emergency vehicles. Failing to move over or slow down for a stationary authorized emergency vehicle displaying flashing lights is a Level 6 felony when it results in serious bodily injury, catastrophic injury or death to a person operating, occupying or affiliated with that vehicle (IC 9-21-8-35(b)).

Leaving the scene of a fatal crash

Failing to stop after an accident is a Level 4 felony "if the accident results in the death or catastrophic injury of another person," and a Level 3 felony if the operator knowingly or intentionally fails to stop or comply during or after committing operating while intoxicated causing serious bodily injury or causing death or catastrophic injury (IC 9-26-1-1.1(b)(3)-(4)). See Indiana hit-and-run laws for the duties at the scene.

Sentencing rules for voluntary manslaughter

Beyond the Level 2 range, two provisions apply to voluntary manslaughter:

• Limited suspension. A court may suspend any part of a felony sentence, but for a Level 2 felony it "may suspend only that part of a sentence that is in excess of the minimum sentence" (IC 35-50-2-2.2(b)). The Level 2 minimum is 10 years.
• Lifetime parole. A person convicted of voluntary manslaughter, like a person convicted of murder, "shall be placed on parole for the remainder of the person's life" after completing the fixed term, less credit time earned (IC 35-50-6-1(e)).

Indiana's definition of "crime of violence" in IC 35-31.5-2-79 lists voluntary manslaughter, involuntary manslaughter, reckless homicide and operating a vehicle while intoxicated causing death or catastrophic injury.

Other homicide offenses below murder

Dealing in a controlled substance resulting in death, IC 35-42-1-1.5, is a separate offense in the homicide chapter, not a form of manslaughter. A person who knowingly or intentionally manufactures or delivers a controlled substance in violation of the listed dealing statutes (cocaine or a narcotic drug, methamphetamine, or a schedule I, II, or III controlled substance) that "results in the death of a human being who used the controlled substance" commits a Level 1 felony, punishable by 20 to 40 years with an advisory sentence of 30 years (IC 35-50-2-4(b)). The same result is a Level 2 felony when the dealing violates IC 35-48-4-3 (a schedule IV controlled substance), and a Level 3 felony when it violates IC 35-48-4-4 (schedule V) or involves a synthetic drug, a controlled substance analog or a substance represented to be a controlled substance (IC 35-42-1-1.5(b), (c)). Under subsection (d), it is not a defense that the person who died used the substance voluntarily or used it in combination with alcohol or another substance.

Suicide-related offenses and feticide. Causing suicide, intentionally causing another human being to commit suicide by force, duress or deception, is a Level 3 felony (IC 35-42-1-2). Assisting suicide, intentionally providing the physical means for, or participating in a physical act of, another person's suicide or attempt with knowledge of that person's intent, is a Level 5 felony (IC 35-42-1-2.5(b)); subsection (a) excludes listed pain-relief and treatment decisions by licensed health care providers. Feticide, knowingly or intentionally terminating a human pregnancy with an intention other than to produce a live birth or to remove a dead fetus, is a Level 3 felony (IC 35-42-1-6(b)); it does not apply to the pregnant mother or to the medical treatment and procedures listed in subsection (a), and section 6.5 excludes an abortion performed in compliance with IC 16-34-2.

Recent amendments

The current text of IC 35-42-1-3 and IC 35-42-1-4 carries P.L.203-2018 as its most recent amendment, and IC 35-42-1-5 carries P.L.158-2013. The OWI-death section, IC 9-30-5-5, was most recently amended by P.L.186-2025.

OWI and watercraft (2026). P.L.158-2026, effective July 1, 2026, specified that a vehicle for the crime of operating while intoxicated includes a watercraft, repealed the separate crime of operating a motorboat while intoxicated (IC 35-46-9), and requires a law enforcement officer to offer a chemical test that includes a blood test to any person the officer has reason to believe operated a vehicle involved in a fatal accident. Offenses committed before July 1, 2026 were governed by the earlier text.

Federal law

Federal law, 18 U.S.C. 1112, covers manslaughter within the special maritime and territorial jurisdiction of the United States; see the manslaughter laws hub for how the federal offense works.

Under IC 35-42-1-5, a person who recklessly kills another human being commits reckless homicide, a Level 5 felony. Recklessly means acting in plain, conscious and unjustifiable disregard of harm that might result, where the disregard is a substantial deviation from acceptable standards of conduct (IC 35-41-2-2(c)).

What is the penalty for a fatal drunk driving crash in Indiana?

Causing a death while operating a vehicle with an alcohol concentration of at least 0.08, with a Schedule I or II controlled substance or its metabolite in the blood, or while intoxicated is a Level 4 felony under IC 9-30-5-5, with a fixed term of 2 to 12 years and an advisory sentence of 6 years. Each person killed is a separate offense.

Indiana has no offense with that name. A death caused while operating a vehicle while intoxicated is charged under IC 9-30-5-5 (Level 4), and the reckless homicide statute, IC 35-42-1-5 (Level 5), covers a reckless killing by any means. Since July 1, 2026, IC 9-30-5-5 also covers operating a watercraft while intoxicated.

What is sudden heat in Indiana?

The statute does not define it. In Suprenant v. State (2010), the Indiana Court of Appeals described sudden heat as anger, rage, resentment, or terror sufficient to obscure the reason of an ordinary person, preventing deliberation and premeditation, and said words alone do not constitute sufficient provocation to warrant a voluntary manslaughter instruction.

Is leaving the scene of a fatal crash a felony in Indiana?

Yes. Under IC 9-26-1-1.1(b)(3), it is a Level 4 felony if the accident results in the death or catastrophic injury of another person, and a Level 3 felony under (b)(4) if the operator knowingly or intentionally fails to stop or comply during or after committing operating while intoxicated causing serious bodily injury or causing death or catastrophic injury.
