What Counts as Manslaughter in Missouri?
Under Missouri law, manslaughter is divided into two primary categories: voluntary manslaughter and involuntary manslaughter. In addition, involuntary manslaughter is further classified into first-degree and second-degree offenses, each with distinct legal elements and potential penalties.
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
}
Under RSMo § 565.024, first-degree involuntary manslaughter is recklessly causing someone else’s death. “Recklessly” is defined as knowing there is a serious risk that their actions could cause harm, but they ignore that risk and do it anyway, acting more carelessly than a reasonable person would in that same situation.
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.
