What Is Manslaughter Under Missouri Law?
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.
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.
Under RSMo § 565.027, second-degree involuntary manslaughter is defined as causing someone’s death by acting with criminal negligence. A person acts with “criminal negligence” when they fail to notice a serious risk that their actions could cause harm, even though a reasonable person in the same situation would have recognized the danger and acted more carefully.

Common Situations That Lead to Manslaughter Charges in Des Peres, MO
Most manslaughter cases in Des Peres, MO don’t start with intent, they start with something going wrong.
