What Counts as Manslaughter in Missouri?
In Missouri, manslaughter isn’t a single charge, it’s broken into different categories depending on the situation in St. Louis, MO. The law recognizes both voluntary manslaughter and involuntary manslaughter. Involuntary manslaughter is further divided into first-degree and second-degree, each with different standards and consequences.
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.
