Quick Reference: Felon in Possession

What the Law Actually Says

Missouri and federal law both prohibit felon firearm possession, but with different scopes, different penalty structures, and different procedural frameworks.

Missouri (§571.070)

Missouri’s statute prohibits firearm possession by convicted felons, persons adjudicated mentally incompetent, and fugitives from justice. The classification escalates based on the nature of the prior criminal history:

A prior nonviolent felony results in a Class D Felony — up to 7 years. A prior dangerous felony or violent felony elevates the charge to Class C — up to 10 years. Two or more prior violent felony convictions push the charge to Class B — 5 to 15 years. And if the firearm is possessed during the commission of another felony, the classification increases by one additional level.

Missouri’s statute focuses primarily on felony convictions as the disqualifying condition. The state prohibition does not explicitly cover domestic violence misdemeanor convictions (that is a federal prohibition) or unlawful drug users (also primarily a federal prohibition), though those categories can trigger federal charges arising from the same conduct.

Federal (18 U.S.C. §922(g))

Federal law casts a wider net. Nine separate categories of prohibited persons are defined:

Convicted felons (any jurisdiction). Fugitives from justice. Unlawful users of or persons addicted to controlled substances. Persons adjudicated as mental defectives or committed to mental institutions. Illegal aliens. Persons dishonorably discharged from the military. Persons who have renounced United States citizenship. Persons subject to certain domestic violence restraining orders. Persons convicted of misdemeanor crimes of domestic violence.

The federal prohibition on ammunition is separate from the firearm prohibition — possessing a single round of ammunition as a prohibited person violates federal law. And the “interstate commerce” element — which requires that the firearm or ammunition traveled in interstate commerce at some point — is virtually always satisfied because nearly all firearms and ammunition cross state lines during manufacture or distribution.

Federal penalties include up to 10 years imprisonment at base. For defendants who qualify under the Armed Career Criminal Act — three or more prior convictions for violent felonies or serious drug offenses — the mandatory minimum is 15 years. ACCA’s definition of “violent felony” has been extensively litigated in federal courts, and whether a specific prior conviction qualifies as an ACCA predicate is frequently the most critical legal question in a federal felon-in-possession case.

Dual Prosecution Risk

A defendant can be prosecuted under both Missouri §571.070 and federal 18 U.S.C. §922(g) for the same act of possession. This is not double jeopardy — the dual sovereignty doctrine permits separate state and federal prosecution because the state and federal governments are considered separate sovereigns.

In practice, the decision of whether to prosecute a case in state court, federal court, or both depends on the defendant’s criminal history, the circumstances of the arrest, whether the case was investigated by federal agents or task forces, and the priorities of the respective prosecutors’ offices. Defense counsel’s ability to influence this charging decision — through early engagement, presentation of mitigating circumstances, and strategic positioning — can have a greater impact on the outcome than any motion or argument filed after charges are brought.

Elements the Prosecution Must Prove

State (§571.070):

1. The defendant possessed a firearm. Actual or constructive possession. Constructive possession requires proof that the defendant knew the firearm was present, had access to it, and intended to exercise control over it. Mere proximity — being in the same room, the same vehicle, or the same residence as a firearm — is not sufficient.
2. The defendant was a prohibited person. Proven through certified court records of the prior felony conviction, mental health adjudication, or fugitive status. The records must be authenticated and must establish that the disqualifying condition existed at the time of the alleged possession.
3. The defendant knew of the firearm and their prohibited status. Knowledge of both the weapon’s presence and the legal prohibition.

Federal (18 U.S.C. §922(g)):

1. The defendant knowingly possessed a firearm or ammunition. Same actual/constructive possession standard.
2. The defendant had a qualifying prior conviction or disqualifying condition. Proven through certified records.
3. The firearm or ammunition traveled in interstate commerce. A jurisdictional element that is virtually always established through stipulation or manufacturing records showing the firearm was made in a different state than where it was possessed.

Classification and Penalties

When ACA (§571.015) is stacked with felon in possession at the state level — which occurs when the firearm possession is connected to another felony — the defendant faces an additional 3 to 15+ years of mandatory consecutive prison time with no probation and 85% mandatory minimum. The combination of felon in possession plus ACA can create total state exposure exceeding 25 years.

Defense Strategies That Work in Felon-in-Possession Cases

Constructive Possession Challenges

The single most effective defense in many felon-in-possession cases. When a firearm is found in a shared vehicle, a common area of a residence, or any location accessible to multiple people, the State must prove that the specific defendant — not a co-resident, roommate, passenger, or visitor — had knowledge of and control over the weapon.

The defense examines every aspect of the possession theory: Where exactly was the firearm found? Who else had access to that location? Whose fingerprints or DNA are on the weapon? Were the defendant’s personal items found near the firearm, or were other people’s belongings closer? Did the defendant make statements at the time of discovery suggesting awareness — or lack of awareness — of the firearm? Was the defendant observed interacting with or reaching toward the location where the firearm was found?

In multi-occupant vehicles — one of the most common fact patterns — constructive possession is highly contestable. A firearm found under the rear seat of a car with four occupants could belong to any of them, and the State’s burden to prove which specific individual possessed it creates substantial reasonable doubt.

Challenging the Predicate Conviction

The entire prohibition rests on the prior felony conviction. If that conviction was constitutionally defective, it cannot serve as a valid predicate:

Lack of counsel. If the defendant was not represented by counsel during the prior felony proceedings — and did not knowingly and voluntarily waive the right to counsel — the conviction may be invalid under the Sixth Amendment.

Unknowing or involuntary plea. If the prior guilty plea was not made knowingly, voluntarily, and intelligently — if the defendant was not advised of the rights being waived, the potential penalties, or the consequences of the plea — the conviction may be subject to challenge.

Expungement. If the prior felony has been expunged under §610.140, RSMo, Missouri state firearm rights are generally restored. However, federal rights may not be — creating the unusual situation where a person can legally possess firearms under state law but remain prohibited under federal law. Whether the expungement qualifies as a “restoration of rights” under federal law depends on the specific terms of the state expungement and the circuit court’s interpretation.

Second Amendment / Bruen Challenges

The Supreme Court’s 2022 Bruen decision reshaped Second Amendment jurisprudence by requiring firearms restrictions to be “consistent with this Nation’s historical tradition of firearm regulation.” Defense attorneys are using this framework to challenge felon-in-possession statutes as applied to nonviolent offenders — arguing that the historical tradition of firearms regulation did not include blanket prohibitions on all felons regardless of the nature of the offense.

This argument has particular force when applied to defendants whose prior convictions involved drug possession, property crimes, financial offenses, or other nonviolent conduct. The historical record does not support a tradition of disarming persons convicted of nonviolent offenses, and several federal district courts and circuit courts have found felon-in-possession statutes unconstitutional as applied to specific nonviolent offenders. The Eighth Circuit (which covers Missouri) continues to develop this case law, and Bruen-based challenges represent a genuine and evolving defense avenue.

Suppression of the Firearm

Fourth Amendment challenges apply with full force in felon-in-possession cases. If the firearm was discovered through an unlawful search — regardless of the defendant’s prohibited status — the evidence is suppressed and the case fails.

Common suppression scenarios in felon-in-possession cases include traffic stops where officers lacked reasonable suspicion, frisks conducted without articulable safety concerns under Terry v. Ohio, vehicle searches based on expired consent or without probable cause, probation or parole home visits that exceeded the scope of supervision conditions, and inventory searches of vehicles that did not follow departmental policy.

Challenging ACCA Predicates at the Federal Level

When federal prosecution triggers ACCA’s 15-year mandatory minimum, defense attorneys scrutinize every prior conviction the government claims qualifies. ACCA requires three prior convictions for “violent felonies” — and the Supreme Court’s decisions in Johnson v. United States (2015), Mathis v. United States (2016), and subsequent cases have narrowed the definition significantly. Prior convictions for burglary, drug offenses, and other offenses that were previously treated as ACCA predicates may no longer qualify under the current legal framework.

Removing even one qualifying conviction from the ACCA analysis drops the defendant below the three-conviction threshold and eliminates the 15-year mandatory minimum entirely — reducing maximum federal exposure from 15+ years to 10 years. This analysis is technical, requiring a categorical approach that examines the elements of the prior offense statute rather than the defendant’s actual conduct, and it demands attorneys who are familiar with federal sentencing law.
