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 law, voluntary manslaughter typically involves situations where someone causes a death during a moment of intense emotion or provocation—circumstances that would otherwise qualify as second-degree murder. It can also include knowingly assisting someone in taking their own life:
- 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.
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.
