Missouri Felony Classifications and Penalties

Missouri classifies felonies into five classes under §558.011, RSMo, with sentencing ranges that escalate based on the class and the defendant’s criminal history:¹

The Dangerous Felony Designation — 85% Minimum

Certain felonies carry a “dangerous felony” designation under §556.061(19), RSMo — requiring 85% of the sentence to be served before parole eligibility.² No good time credit. No early release. No reduction for program completion. A 15-year sentence on a dangerous felony means 12 years and 9 months minimum before any possibility of parole.

Dangerous felonies include murder in the second degree, assault in the first degree, domestic assault in the first degree, robbery in the first degree, kidnapping in the first degree, rape in the first degree, sodomy in the first degree, arson in the first degree, burglary in the first degree, Armed Criminal Action, and drug trafficking at the Class A or B level.²

Prior and Persistent Offender Enhancements

Missouri’s prior and persistent offender statutes under §558.016, RSMo allow prosecutors to seek enhanced sentencing for defendants with criminal history.³ A “prior offender” (one or more prior felony convictions) faces the authorized term of imprisonment for the next higher class of felony. A “persistent offender” (two or more prior felony convictions) faces the authorized term for the class two steps higher. These enhancements can transform a Class D Felony (7-year maximum) into a Class B Felony exposure (5–15 years).

Types of Felony Cases We Handle

Drug Felonies

Drug offenses constitute a significant share of felony filings in the St. Louis metro area. Possession of a controlled substance (non-marijuana) is a Class D Felony under §579.015.⁴ Possession with intent to distribute is a Class C Felony.⁵ Trafficking — triggered by substance-specific weight thresholds — is a Class B or Class A dangerous felony.⁶ Manufacturing methamphetamine or fentanyl is automatically a Class B dangerous felony.⁷ Drug felonies are among the most defensible cases we handle — Fourth Amendment challenges, constructive possession arguments, and drug court diversion all create paths to reduced charges or dismissal. Drug charges →

Violent Felonies

Assault, robbery, kidnapping, and other violent offenses carry some of the most severe penalties in Missouri’s criminal code. First-degree assault is a Class B/A dangerous felony.⁸ Robbery in the first degree is a Class A/B dangerous felony.⁹ When a weapon is involved, Armed Criminal Action adds a mandatory consecutive sentence — 3 to 15+ years — with no probation.¹⁰ Self-defense, eyewitness identification challenges, and charge classification disputes are central to violent felony defense. Violent crimes → | Assault defense →

Weapons Felonies

Weapons charges range from Class E (unlawful use of weapon) to Class B with 15-year mandatory minimums (enhanced shooting offenses). Armed Criminal Action — the enhancement that attaches to any felony involving a weapon — adds mandatory consecutive prison time.¹⁰ Felon in possession charges carry Class D through Class B exposure depending on criminal history, plus the risk of federal prosecution under 18 U.S.C. §922(g).¹¹ Weapons charges →

Sex Offense Felonies

Sex crime convictions carry prison time plus sex offender registration under §589.400, RSMo — which can last 15 years, 25 years, or a lifetime depending on the offense.¹² The collateral consequences of sex offender registration are among the most severe in the criminal code: residency restrictions, employment limitations, public notification, and social stigma. Sex crimes →

DWI Felonies

Missouri’s DWI offender classification system turns DWI into a felony at the persistent offender level (two prior alcohol-related enforcement contacts).¹³ Persistent DWI is a Class E Felony. Aggravated is Class D. Chronic is Class C. Habitual offender is a Class B Felony — 5 to 15 years.¹³ DWI defense →

Property Felonies

Felony stealing (over $750), burglary, robbery, arson, and major property damage all carry felony-level penalties. First-degree burglary is a Class B dangerous felony.¹⁴ Robbery in the first degree is a Class A/B dangerous felony.⁹ Theft charges → | Property crimes → | Burglary →

Felony Defense Strategies

Preliminary Hearing Challenges

Felony cases in Missouri require either a preliminary hearing or a grand jury indictment before proceeding to trial. The preliminary hearing is the first opportunity to cross-examine the State’s witnesses under oath and expose weaknesses in the case. A strong preliminary hearing performance can lead to charge reductions, dismissals, or a more favorable negotiating position.

Suppression Motions

Fourth Amendment challenges to searches and seizures are critical in felony cases — particularly drug, weapons, and property cases where physical evidence is the foundation of the prosecution. If the search was unlawful, the evidence is excluded regardless of its reliability. Suppression motions frequently result in charges being dismissed or reduced when the State cannot prove its case without the suppressed evidence.

SIS — Suspended Imposition of Sentence

For eligible felonies, an SIS allows a defendant to plead guilty, complete probation, and have the guilty plea set aside — meaning no felony conviction appears on the record. This is one of the most powerful sentencing tools in Missouri criminal defense. An SIS preserves employment opportunities, firearm rights (in most cases), and professional licensing eligibility.¹⁵ Not every felony qualifies for SIS, and not every judge grants it — but experienced defense counsel knows when to pursue it and how to present the case for it.

120-Day Program

Under §559.115, RSMo, certain felony defendants can serve a short period of shock incarceration (typically 120 days in the Department of Corrections) followed by release to supervised probation.¹⁶ If the defendant performs well during the institutional period, the court may place them on probation for the remainder of the sentence. This program is specifically available for drug offenses and many nonviolent felonies.

Negotiation and Charge Reduction

Not every felony case needs to go to trial. Effective plea negotiation — reducing charges, eliminating enhancements, securing probationary sentences instead of prison — requires an attorney who understands the strengths and weaknesses of both the State’s case and the defense. Negotiating the dismissal of an Armed Criminal Action enhancement, for example, can reduce sentencing exposure by years or decades.

Trial

When the State cannot meet its burden — when the evidence is weak, when witnesses are unreliable, when constitutional violations undermine the case — our attorneys take cases to trial. Not every case should be tried. But when the facts support it, a jury trial is the most powerful defense tool available. Our trial experience spans every type of felony in Missouri’s criminal code.
