Missouri Violent Crime Classifications and Penalties

Homicide Offenses

Murder in the First Degree (§565.020)

The most serious charge in Missouri’s criminal code. A person commits first-degree murder by knowingly causing the death of another person after deliberation — meaning cool reflection for any period of time, however brief.¹ This is a Class A Felony: the death penalty or life imprisonment without the possibility of parole.¹ First-degree murder is a dangerous felony — 85% of any non-death sentence must be served before parole eligibility under §558.019, RSMo.²

Murder in the Second Degree (§565.021)

Second-degree murder covers two categories: knowingly causing a death without deliberation, or felony murder — a death that occurs during the commission of or flight from a dangerous felony, even if unintentional.³ Class A Felony — 10 to 30 years or life.³ A dangerous felony under §556.061 — 85% mandatory minimum before parole.² Under SB 888’s new mandatory minimums, Class A felony convictions also require 70% of any non-dangerous-felony portion served — but for murder 2nd, the 85% dangerous felony rule governs.

Voluntary Manslaughter (§565.023)

Causing a death under sudden passion arising from adequate cause — provocation by the victim that would produce passion in a person of ordinary temperament.⁴ Class B Felony — 5 to 15 years.⁴ Under SB 888, Class B felony convictions now require 50% of the sentence served before parole eligibility.

Involuntary Manslaughter — First Degree (§565.024)

Recklessly causing the death of another person. Class C Felony — 3 to 10 years.⁵ Elevates to Class B if the victim is a law enforcement officer.⁵ The most common application is DWI cases where a death results. Under SB 888, Class C felonies require 40% served before parole eligibility.

Involuntary Manslaughter — Second Degree (§565.027)

Criminal negligence causing death. Class E Felony — up to 4 years.⁶ Elevates to Class D if the victim is a law enforcement officer.⁶ Under SB 888, Class D and E felonies require 25% served before parole eligibility.

Robbery

Robbery in the First Degree (§570.023)

Forcibly stealing while causing serious physical injury, while armed with a deadly weapon, while using or threatening use of a dangerous instrument, or while displaying or threatening to use what appears to be a deadly weapon.⁷ Class A Felony at base when serious physical injury results — Class B Felony otherwise.⁷ A dangerous felony — 85% mandatory minimum before parole.² Armed with a weapon plus robbery in the first degree often draws an Armed Criminal Action charge as well, adding a mandatory consecutive sentence of 3 years minimum.⁸

Robbery in the Second Degree (§570.025)

Forcibly stealing property — using or threatening immediate physical force to prevent resistance or compel delivery — without the aggravating elements of first-degree robbery. Class C Felony — 3 to 10 years.⁹ Under SB 888, 40% minimum must be served before parole eligibility.

Vehicle Hijacking (§570.027)

Knowingly using or threatening force to steal a motor vehicle from a person in possession. Class B Felony at base — escalating to Class A when serious physical injury results or a weapon is used.¹⁰ A dangerous felony at the Class A level — 85% mandatory minimum.²

Kidnapping

Kidnapping in the First Degree (§565.110)

Unlawfully confining another person for the purpose of ransom, to use as a hostage or shield, to terrorize the victim or another, to interfere with a government function, to facilitate a felony or flight, to inflict serious injury, or to commit a sexual offense.¹¹ Class A Felony — 10 to 30 years or life.¹¹ Reduces to Class B if the victim is released unharmed in a safe place.¹¹ A dangerous felony — 85% mandatory minimum.²

Child Kidnapping (§565.115)

Kidnapping a child under 14 when the perpetrator is not the child’s parent or guardian. Class A Felony — life imprisonment or a minimum of 10 years.¹² A dangerous felony — both the 85% mandatory minimum and a 10-year mandatory minimum before any parole eligibility.¹²

Kidnapping in the Second Degree (§565.120)

Unlawfully confining another person without consent. Class D Felony — up to 7 years.¹³ Elevates to Class C when the victim is under 14.¹³

Weapons Enhancement — Armed Criminal Action

When any violent felony involves a deadly weapon, prosecutors routinely charge Armed Criminal Action (§571.015, RSMo) as a separate count.⁸ ACA adds a mandatory consecutive sentence of 3 to 15 years — served after the underlying violent crime sentence — with no probation and no early release.⁸ ACA is itself a dangerous felony, requiring 85% of that consecutive sentence before parole eligibility.² In a first-degree robbery case with ACA, a defendant can face a combined mandatory minimum of decades before any parole consideration.

Defense Strategies for Violent Crime Cases in St. Louis

Self-Defense

Missouri’s self-defense law under §563.031, RSMo is broad.¹⁴ A person may use physical force — including deadly force — when they reasonably believe such force is necessary to protect against the imminent use of unlawful force. The castle doctrine (§563.031.2) eliminates any duty to retreat inside a home, vehicle, or private property a person lawfully occupies.¹⁴ Stand-your-ground (§563.031.3) eliminates the duty to retreat anywhere a person is lawfully present and not engaged in criminal activity.¹⁴ Self-defense is a complete defense to violent crime charges. When the evidence supports it, the State cannot obtain a conviction.

Challenging the Identification

Eyewitness identification is among the least reliable evidence in criminal trials — particularly in the high-stress, often brief circumstances of violent confrontations. Cross-racial identifications, identifications based on a fleeting observation, and identifications influenced by suggestive lineup procedures are all challengeable. Defense attorneys examine the photo array or lineup administration, the witness’s opportunity to observe, and inconsistencies between the initial description and subsequent identification.

Challenging the Forensic and Physical Evidence

Violent crime prosecutions often rely on physical evidence — DNA, fingerprints, surveillance footage, ballistic evidence, and blood spatter analysis. Each piece requires proper collection, preservation, and chain of custody. Errors in forensic procedures, contaminated samples, unreliable analytical methods, and expert testimony that overstates certainty are all grounds for challenge. Defense attorneys retain independent experts to review the State’s forensic evidence and present alternative interpretations.

Challenging Felony Murder Charges

Felony murder charges are among the most legally aggressive theories prosecutors use — holding a defendant responsible for a death that occurred during a dangerous felony even if the defendant did not intend to kill anyone and did not pull the trigger. Defense attorneys challenge felony murder by contesting whether the underlying felony qualifies as a predicate offense, whether the death was causally connected to the felony, and whether the defendant’s actions were a proximate cause of the death.

Negotiating Charge Classification

The difference between first-degree and second-degree robbery, or between murder in the first and second degree, can mean decades — and the dangerous felony designation. Defense attorneys challenge overcharging, negotiate the charge down to the classification the evidence actually supports, and in many cases can eliminate the dangerous felony designation entirely — which transforms the mandatory minimum from 85% to the lower percentages now established under SB 888.

Preliminary Hearing Challenges

Missouri felony cases require a preliminary hearing or grand jury indictment before proceeding to trial. The preliminary hearing is the first opportunity to cross-examine the State’s witnesses under oath — before they have been fully prepared for trial testimony. A strong preliminary hearing performance exposes weaknesses, locks witnesses into statements, and frequently produces charge reductions or more favorable plea negotiations.

Suppression Motions

When law enforcement violated the Fourth Amendment — conducting an unlawful search, making an arrest without probable cause, or obtaining a confession through coercion — the evidence obtained must be suppressed. In violent crime cases, suppression of key physical evidence or a confession can eliminate the State’s ability to proceed at all.
