Involuntary Manslaughter in Chicago

Involuntary manslaughter occurs when you unintentionally cause the death of another person. It is the least serious crime of homicide because it is committed without intent, planning, or malice. Instead, your reckless behavior creates an unjustifiable risk of harm and results in the death of another person.

In Chicago, you can be charged with involuntary manslaughter, as defined in 720 ILCS 5/9-3, if you:

  1. Unintentionally kill another person without lawful justification,
  2. While performing acts that, whether lawful or unlawful, were likely to cause death or great bodily harm.

Unjustifiable Risk of Great Bodily Harm or Death

In order to convict you of involuntary manslaughter, the prosecution must be able to establish each element of the crime. This includes proving that you acted in a way that created an unjustifiable risk of harm. You will be considered to have acted recklessly if:

  1. You know that your behavior could cause great bodily harm or death,
  2. Ignore this risk, and
  3. Perform those acts anyway.

One way to determine if your conduct was reckless is asking what a reasonable person acting under similar circumstances would have done. Would a reasonable person have known that their conduct created an unjustifiable risk of harm? If they had this knowledge, would they have committed the act, anyway?

Reckless Homicide

Reckless homicide is a very closely related crime to involuntary manslaughter. In fact, reckless homicide is the crime of involuntary manslaughter while operating a motor vehicle. If you unintentionally kill another person while driving a car, truck, snowmobile, or boat you will face charges for reckless homicide.

Penalties for Involuntary Manslaughter

Absent any aggravating factors, involuntary manslaughter and reckless homicide are both Class 3 Felony offenses in Chicago. A Class 3 Felony conviction for involuntary manslaughter is punishable by 2-5 years in an Illinois state prison and/or $25,000 in fines.

Reckless homicide and/or involuntary manslaughter may be charged as a Class 2 Felony in Chicago in any of the following situations:

  • Reckless homicide committed on a public school crossing;
  • Reckless homicide committed in a maintenance or construction zone;
  • Involuntary manslaughter causing the death of a peace officer; or
  • Reckless homicide or involuntary manslaughter resulting in the deaths of 2 or more people.

These Class 2 Felony offenses can be punished by a minimum of 3 years in prison to a maximum of 28 years in prison. The specific penalty will depend on the details of your case.

Defending Involuntary Manslaughter Charges

You have the right to defend yourself against any accusations of criminal wrongdoing. When you are charged with a crime this means that you can assert any legal defense that helps to explain, excuse, or justify your alleged behavior. When a defense is successful the state’s attorney will have a difficult time proving their case beyond a reasonable doubt. Your attorney will use this as leverage to secure a reduction in charges or a full dismissal of your case. Defenses that may be helpful in your Chicago involuntary manslaughter case include:

  • Self-defense or defense of another person;
  • Your conduct was accidental, not reckless;
  • Insanity; and/or
  • Violation of your Constitutional rights.
