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 Jefferson County, 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.
According to Missouri Revised Statute § 565.023, voluntary manslaughter generally involves:
- A killing that would otherwise qualify as second-degree murder, but occurs under sudden passion resulting from adequate provocation; or
- Knowingly assisting another person in committing suicide
:
- 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.
Second-degree involuntary manslaughter, under RSMo § 565.027, involves criminal negligence. In these cases, a person fails to recognize a serious risk that a reasonable person would have noticed and avoided.
