How Missouri Law Defines Manslaughter
Missouri law recognizes two primary forms of manslaughter: voluntary manslaughter and involuntary manslaughter. In addition, involuntary manslaughter is further divided into first-degree and second-degree offenses, each carrying different legal standards and penalties.
Under Missouri Revised Statute § 565.023, voluntary manslaughter is:
- Killing someone in a way that would normally be second-degree murder, but they did it under sudden passion caused by something serious enough to make them lose self-control; or
- Knowingly helping someone commit suicide
}
First-degree involuntary manslaughter, under RSMo § 565.024, involves acting recklessly—meaning a person is aware of a serious risk but ignores it anyway. This goes beyond a simple mistake and reflects a conscious disregard for safety.
Under RSMo § 565.027, second-degree involuntary manslaughter occurs when a person causes death through criminal negligence—failing to recognize a substantial risk that a reasonable person would have identified and avoided.
