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 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.

Manslaughter vs. Murder in St. Louis County, MO: Why the Difference Matters

The difference between manslaughter and murder in St. Louis County, MO can significantly impact sentencing and long-term consequences.

  • Murder usually means the prosecution believes there was intent or planning involved
  • Manslaughter often involves situations where someone acted recklessly, negligently, or in the heat of the moment

It’s also important to understand that prosecutors may initially pursue the most serious charges available. That’s why early involvement from an experienced manslaughter defense lawyer in St. Louis County, MO is essential to developing a strong legal strategy.

What Typically Leads to Manslaughter Charges in St. Louis County, MO?

In St. Louis County, MO, manslaughter charges often stem from incidents where a situation escalated or a critical mistake was made, rather than from an intentional act to cause harm.

DWI-Related Accidents
