Missouri First-Degree Burglary Lawyers
Burglary Charges Are Often Built Around Assumptions
What was intended, what can be proven, and what happened matters.
What separates first-degree burglary from every lesser burglary charge is not the entry. It is what the State claims happened during it. The statute takes an ordinary unlawful entry and elevates it only when one of three aggravating circumstances is present: a deadly weapon or explosives, actual or threatened injury to someone, or a non-participant inside the structure.
Good people end up charged with this offense more often than you would think. A dispute over who had permission to be somewhere. A theft that turned into something more because a roommate was home. A confrontation that the State recharacterizes after the fact.
An arrest is not a conviction, and the aggravating element the State needs is frequently the weakest part of its case. The prosecution has to prove every piece beyond a reasonable doubt, including the one that turns a Class D felony into a Class B. We build the defense early, while the scene, the timeline, and the witness accounts are still fresh, and we hold the State to proving the fact that makes this charge what it is.

What first-degree burglary means under Missouri law
First-degree burglary is an unlawful entry made dangerous. Under § 569.160, RSMo, the offense is an unlawful entry into a building or inhabitable structure, made for the purpose of committing an offense inside, that also involves one of three aggravating circumstances.¹
“A person commits the offense of burglary in the first degree if he or she knowingly enters unlawfully or knowingly remains unlawfully in a building or inhabitable structure for the purpose of committing an offense therein, and when in effecting entry or while in the building or inhabitable structure or in immediate flight therefrom, the person or another participant in the offense: (1) Is armed with explosives or a deadly weapon; or (2) Causes or threatens immediate physical injury to any person who is not a participant in the crime; or (3) There is present in the structure another person who is not a participant in the crime.”¹
A few terms carry more weight than they appear to. “Inhabitable structure,” defined in § 569.010, RSMo, reaches beyond houses to include vehicles, vessels, and any structure where people assemble or lodge.² The purpose element is broad too. The offense you intended inside does not have to be theft, and it does not have to be completed. Intent to commit any offense, formed at the time of the unlawful entry or unlawful remaining, is enough.
The charge did not change in substance in the 2017 revision of the criminal code, but the class did. First-degree burglary remains a Class B felony under current law.¹
What the State has to prove
To convict you of first-degree burglary, the prosecution must prove each of the following beyond a reasonable doubt.¹ ² Miss one, and the charge fails or drops to a lesser offense. That is where the defense begins.
You knowingly entered or remained unlawfully. This is the trespass core of the charge. The State must show you knew you had no license or privilege to be in the building or inhabitable structure. Consent, a genuine right to enter, or a good-faith belief that you were permitted to be there negates this element. Ambiguity about who had authority over a space is a common factual battleground, especially in disputes between people who once shared access to a home.
You acted for the purpose of committing an offense inside. Intent to commit an offense must exist at the moment of unlawful entry or unlawful remaining. Someone who enters to escape the weather, to retrieve their own property, or under a mistaken belief of permission has not committed burglary, even if a trespass occurred. The State frequently infers this intent from circumstances, and inferred intent is contestable.
An aggravating circumstance was present. This is the element that defines the charge. During entry, while inside, or in immediate flight, either you or another participant (a) was armed with explosives or a deadly weapon, (b) caused or threatened immediate physical injury to a non-participant, or (c) a non-participant was present in the structure. If the State cannot prove at least one of these three, the offense is not first-degree burglary.
The aggravating circumstance is the whole case
Here is what most people charged with this offense do not realize. The break-in itself is the easy part for the prosecution. The hard part is the fact that turns second-degree burglary into first. Attack that fact, and the entire charge is exposed.
Second-degree burglary under § 569.170, RSMo covers the same unlawful entry for the purpose of committing an offense, without any of the three aggravators. The line between the two degrees is drawn entirely by subdivisions (1) through (3). When the State cannot prove a weapon, an injury, or a non-participant’s presence, the charge should reduce.
Each aggravator has soft edges. Whether an object is a “deadly weapon” and whether you were “armed” with it during entry, presence, or flight is fact-specific. Missouri courts have held that a person can be “armed” even by equipping himself with a weapon he intends to steal, which makes the timing of possession something the defense must scrutinize closely.³ For the presence aggravator, the person in the structure must be a non-participant. If everyone present was involved, or if no one was actually present, subdivision (3) does not attach.
The “immediate flight” language matters just as much. The aggravating factor has to occur during entry, while inside, or in immediate flight from the scene. If a weapon appeared or an injury happened after the burglary was complete and the flight had ended, the aggravator may not attach at all, and the first-degree charge cannot stand on it.
The penalties you are facing
First-degree burglary is a Class B felony. On conviction, the sentence is 5 to 15 years in prison.¹ ⁴ Probation is available in some cases, but it depends heavily on your record and the specific facts.
A prior record changes the math. Under § 558.016, RSMo, prior and persistent offenders face extended terms, and § 558.019, RSMo governs minimum prison terms for certain repeat felony offenders.⁵ ⁶ Whether these provisions apply depends on your criminal history and the circumstances of the charge.
Missouri has no Three-Strikes law. The enhancement framework here is the prior/persistent offender regime, not a strike system.
Collateral consequences. A Class B felony conviction reaches well past the sentence itself.
- Firearms. A felony conviction bars you from possessing firearms under both federal and Missouri law.
- Employment and licensing. A burglary conviction on your record surfaces in background checks and can close off jobs and professional licenses, particularly any position involving access to homes, property, or client premises.
- Immigration. For non-citizens, a burglary conviction can carry serious immigration consequences, including removability. Anyone who is not a U.S. citizen should have the immigration impact reviewed before making any decision in the case.
- Housing. A felony record complicates rental applications and can affect eligibility for certain housing programs.
How these cases get defended
No two burglary cases are the same, but the strongest defenses tend to press on the same pressure points. The outcome is not predetermined. What follows are the angles we examine in a first-degree burglary case.
Reduce it to second degree. This is often the single most valuable move. If the State cannot prove a weapon, an injury, or a non-participant present beyond a reasonable doubt, the charge should drop from a Class B to a Class D felony. Consider a case where someone enters an unlocked garage to take tools and no one is home. Without an aggravator, that is not first-degree burglary, no matter how the police wrote the report.
Attack the intent element. The State must prove you intended to commit an offense inside at the time of entry. Someone who enters a building believing they have permission, or to shelter, or to recover their own belongings, lacks the criminal purpose the statute requires. Inferred intent is vulnerable intent.
Challenge the unlawful entry itself. Consent and a genuine right to be present defeat the charge outright. In disputes between former partners, roommates, or family members, the question of who actually had authority over the space is rarely as clear as the State makes it sound.
Scrutinize the “armed” and “deadly weapon” findings. Whether an object qualifies as a deadly weapon, and whether you were armed with it during the covered window of entry, presence, or immediate flight, is a fact question the defense can contest directly.
Dispute the timing under “immediate flight.” If the aggravating fact arose after the offense was complete and flight had ended, it may not attach to the burglary at all.
Contest identity and the sufficiency of the evidence. Eyewitness identifications are unreliable more often than juries assume. Forensic links can be incomplete, and circumstantial evidence placing you at the scene can have gaps worth exposing.
Move to suppress. Where evidence came from an unlawful search, a warrantless entry, or an improper seizure, or where statements were taken in violation of Miranda, a suppression motion can remove the foundation of the State’s case before trial.
Why work with our firm on a first-degree burglary charge
First-degree burglary turns on a single elevating fact, and defending it well means knowing exactly where that fact is weak. We have handled the range of charges that cluster around these cases in the St. Louis area, from the underlying stealing and property offenses to the assault and armed-criminal-action counts prosecutors often stack on top. St. Louis County felony cases run through the 21st Judicial Circuit in Clayton, while offenses in the City of St. Louis fall to the 22nd Circuit, and we know how these matters move through both. If you are facing a Class B felony that could send you to prison for years over one contested element, the time to build your defense is now.
