Involuntary Manslaughter Lawyer Kansas City, MO
An involuntary manslaughter accusation begins with a death. This means the investigation is emotionally charged from the start. You may be in shock or trying to understand how a simple accident became a felony case. At the same time, detectives may be collecting statements, phone data, video, medical records, vehicle evidence, or expert opinions to try to prove that you were reckless or criminally negligent.
At Combs Waterkotte, we defend people facing life-changing manslaughter charges in Kansas City, Missouri. We listen without judgment, explain your charge in plain language, and test the prosecution’s theory against the evidence. Early representation gives you the opportunity to preserve favorable evidence, manage contact with investigators, and begin building a defense before prosecutors can craft their narrative.
Kansas City, MO Involuntary Manslaughter Charges Explained
Missouri places involuntary manslaughter among its serious violent-crime offenses, but the charge does not require proof that you intended to kill anyone. Instead, the state has to prove a death, causation, and one of two mental states:
- Recklessness (for first-degree involuntary manslaughter)
- Criminal negligence (for second-degree involuntary manslaughter)
Cases can arise from a vehicle collision, mishandling a gun, unsafe supervision, a workplace accident, or a confrontation that prosecutors say involved unjustifiable risk. The death itself does not prove criminal liability. Prosecutors still must specifically connect your conduct to the death and prove either recklessness or criminal negligence beyond a reasonable doubt.
If police are investigating you, quickly take the following steps to protect both yourself and potential evidence:
- Don’t speak to police without contacting a lawyer first.
- Preserve messages, photos, videos, location records, vehicle data, and the names of potential witnesses.
- Don’t post publicly about anything that may relate to the incident or delete or alter any existing social media posts.
A Missouri-side Kansas City case usually moves through the circuit court for the county where the incident allegedly occurred (often Jackson County). The venue, charging practices, and the assigned prosecutor can all have an enormous impact on your case.
Kansas City, Missouri Involuntary Manslaughter Laws
There are two degrees of involuntary manslaughter under Missouri law: first degree and second degree. The charge you face depends on your alleged state of mind when the death occurred, and each offense carries distinct sentencing ranges.
First-Degree Involuntary Manslaughter
RSMo § 565.024 defines first-degree involuntary manslaughter as recklessly causing another person’s death. Under Missouri’s criminal-code definitions, “recklessness” means consciously disregarding a substantial and unjustifiable risk, when that disregard varies greatly from what an ordinary person would do.
First-degree involuntary manslaughter is charged as a Class C felony, but it can become a Class B felony for offenses that result in the death of a police officer.
Second-Degree Involuntary Manslaughter
RSMo § 565.027 defines second-degree involuntary manslaughter as acting with criminal negligence to cause another person’s death. Criminal negligence happens when a person fails to recognize a substantial and unjustifiable risk, and that failure deviates from reasonable care.
Usually, second-degree involuntary manslaughter is charged as a Class E felony. However, it can be elevated to a Class D felony when the charge involves the death of a law enforcement officer.
Defenses Against Kansas City Involuntary Manslaughter Charges
The best defense strategy for your involuntary manslaughter charge depends on exactly what happened, which degree you’re facing, and the evidence available to the prosecution. Your defense team should start by reconstructing a timeline of events before deciding on a defense strategy. The following strategies are common when defending against Kansas City manslaughter allegations.
No Proof of Causation
The state has to prove that your conduct caused the death (rather than showing that the death simply occurred near the same time). Medical evidence, accident reconstruction, toxicology, scene measurements, mechanical inspections, and the acts of others involved may prove an alternative cause of death or damage the prosecution’s theory of what happened. Your defense team may be able to find an expert to test whether the state’s conclusions are scientifically and factually supported.
Lack of Intent
A bad outcome, mistake, or moment of carelessness doesn’t necessarily prove a gross deviation from reasonable care. For first degree involuntary manslaughter, the state must also establish conscious disregard of the risks involved.
An intent and mental-state defense may use witness testimony, safety practices, training records, environmental conditions, or expert analysis to show that prosecutors can’t prove recklessness or criminal negligence beyond a reasonable doubt.
The Event Was an Unavoidable Accident
An accident is not a complete defense if the state can still prove culpability. But an unforeseeable mechanical failure, a sudden medical emergency, an unexpected act by another person, or an inaccurate identification may dispute causation or the mental state required by the statute. Preserving physical evidence and independent videos quickly can be critical because vehicles are repaired, scenes change, and recordings can be overwritten.
Constitutional Violations
It’s not uncommon for individuals facing manslaughter charges to make an incomplete statement that investigators later frame as an admission. Police may also seek a phone, vehicle data, blood evidence, or a search of a home. Your lawyer can examine the chain of custody of evidence, testing methods, warrants, and whether or not you knowingly consented to a search. When evidence is obtained unlawfully, a Fourth Amendment challenge or another motion may limit what a jury is allowed to hear.
Consequences of an Involuntary Manslaughter Conviction in Kansas City, MO

Missouri felony sentencing ranges depend on the degree of the charge and possible statutory enhancements. Prior convictions, multiple counts, and consecutive sentencing can all impact a potential involuntary manslaughter prison sentence. Though each situation is unique, here are the common sentencing ranges:
| Offense | Potential Penalty |
|---|---|
| First degree | Class C felony — 3 to 10 years in prison and a fine up to $10,000 |
| First degree with targeting enhancement | Class B felony — 5 to 15 years in prison |
| Second degree | Class E felony — up to 4 years in prison and a fine up to $10,000 |
| Second degree with targeting enhancement | Class D felony — up to 7 years in prison and a fine up to $10,000 |
Missouri’s felony fine statute authorizes up to $10,000 for Class C, D, and E felonies. A conviction can also come with a slew of collateral consequences, including:
- Barriers to future employment
- The inability to obtain certain professional licenses
- Limited housing options
- Negative impacts on your immigration status
- The loss of your legal firearm rights
If the allegation involves a death that occurred while driving, separate DWI or licensing consequences could apply. A homicide case may also mean exposure to restitution or a civil wrongful-death claim (even if the criminal charge is contested).
