Domestic Assault in the Second Degree in Missouri
Second-Degree Domestic Assault in Missouri Carries Felony Penalties and Lasting Impact
The line between second-degree and lesser charges often comes down to the specific facts — and how they're presented to the court.
Domestic assault in the second degree is a Class D Felony in Missouri — up to 7 years in prison. What makes this charge particularly significant is the strangulation provision: an allegation of choking or strangulation, even without visible injury, automatically supports a felony charge under § 565.073.
What Is Domestic Assault in the Second Degree?
Under RSMo § 565.073, a person commits domestic assault in the second degree when they commit any of the following acts against a domestic victim:
- Knowingly cause physical injury — including by choking or strangulation, OR
- Recklessly cause serious physical injury, OR
- Recklessly cause physical injury by means of a deadly weapon or dangerous instrument¹
Each of these three forms targets a different type of conduct. The first covers intentional harm, including strangulation. The second covers reckless conduct that results in serious injury. The third covers reckless use of a weapon that results in any physical injury.
Missouri Second-Degree Domestic Assault Hinges on Key Distinctions — And Those Distinctions Are Defensible
The Strangulation Provision — Why It Matters
Missouri law explicitly enumerates choking and strangulation as conduct that constitutes second-degree domestic assault under § 565.073(1) — regardless of whether any physical injury results.¹ This is a critical distinction from general assault statutes.
An allegation that the defendant placed hands around the alleged victim’s throat — even without bruising, marks, redness, or any medical findings — can support a Class D Felony charge. Prosecutors in St. Louis County and St. Charles County charge strangulation aggressively. The absence of visible injury does not eliminate the charge; the statute requires only that choking or strangulation occurred, not that it caused a documentable injury.
Strangulation is treated as a categorical indicator of serious intent and escalation risk in domestic violence situations. Research on domestic homicide consistently identifies prior strangulation as a high-risk factor — which is why Missouri law elevated it to automatic felony status under the domestic assault framework.
Who is a “Domestic Victim”?
The domestic assault statutes apply when the alleged victim falls within the categories defined under § 565.002 and § 455.010, RSMo:²
- Current or former spouses
- Persons related by blood or marriage
- Current or former cohabitants (people who live or have lived together)
- Persons who share a child, regardless of relationship history or cohabitation
- Persons in current or former dating or intimate relationships
- Children of household or family members in any of the above categories
This definition is broad. A person who shares a child with the defendant but has never lived with them or been romantically involved qualifies as a domestic victim. A former roommate from years ago may qualify depending on the nature of the relationship. These categories determine whether conduct is charged under the domestic assault statutes or under general assault, and the distinction matters enormously for collateral consequences.
Key Definitions
Physical Injury means physical pain, illness, or any impairment of physical condition.³ This is a lower threshold than serious physical injury — pain alone, without visible injury, satisfies the definition.
Serious Physical Injury means physical injury that creates a substantial risk of death, causes protracted and obvious disfigurement, or causes protracted loss or impairment of a body part or organ.³ This is the element required for the second subsection (recklessly causes serious physical injury) of § 565.073.
Deadly Weapon means a firearm or any instrument readily capable of causing death or serious physical injury when used as a weapon.³ The third subsection — reckless physical injury by a deadly weapon — covers situations where a weapon is used recklessly, causing any level of physical injury.
Classification and Penalties
Domestic assault in the second degree is a Class D Felony under RSMo § 565.073 — up to 7 years in prison and a fine up to $10,000.¹ ⁴
Under SB 888, signed by Governor Kehoe in April 2026, Class D felony convictions now carry a mandatory minimum of 25% of the sentence served before parole eligibility.⁵ A 5-year sentence on a second-degree domestic assault conviction means a minimum of 15 months before any parole consideration.
Second-degree domestic assault is not a dangerous felony — it does not carry the 85% mandatory minimum that applies to first-degree domestic assault. However, with a prior domestic violence or assault conviction, the prior assault offender enhancement under § 565.079 applies, potentially elevating the effective sentencing range.¹
| Classification | Sentence Range | 2026 Parole Minimum |
|---|---|---|
| Class D Felony (base) | Up to 7 years | 25% |
| Enhanced (prior assault offender) | Class C range — up to 10 years | 40% |
Collateral Consequences of a Second-Degree Domestic Assault Conviction
Federal Firearms Prohibition — Permanent
A conviction under § 565.073 is a felony conviction, which triggers a lifetime prohibition on firearm possession under 18 U.S.C. § 922(g)(1).⁶ Unlike some domestic violence consequences that require a misdemeanor conviction, the federal felony firearms ban attaches to any felony conviction. This means loss of firearm rights, concealed carry permit eligibility, and — for those in law enforcement, military, or security — the ability to work in those fields.
No Expungement — Ever
Domestic assault in the second degree is permanently ineligible for expungement under § 610.140(2), RSMo.⁷ No waiting period, no rehabilitation, and no court can expunge this conviction. It will appear on every background check for the rest of the defendant’s life.
Protection Orders
A full order of protection can restrict housing, contact, and custody arrangements from the moment of arrest. Violation of a protection order is a separate criminal offense — Class A Misdemeanor for a first violation, escalating to Class E Felony.⁸
Batterer Intervention
Courts may require completion of a certified batterer intervention program as a condition of any probation or supervised release under § 595.320, RSMo.⁹
Custody and Family Court Impact
A domestic assault conviction carries significant weight in Missouri family court custody proceedings, where domestic violence is an explicit factor in best-interest determinations.
Employment and Immigration
A felony conviction for domestic assault disqualifies applicants from many professional and licensed positions, appears on background checks indefinitely, and — for non-citizens — can trigger removal proceedings under federal immigration law, which specifically designates domestic violence as a deportable offense.
Defense Strategies for Second-Degree Domestic Assault
Challenging the Strangulation Allegation
Strangulation is difficult to prove without physical evidence — and difficult to disprove when the allegation is made. Defense attorneys challenge the medical evidence (or its absence), the alleged victim’s account of the incident, the investigating officer’s documentation, and the chain of events from the initial call through the arrest. The absence of petechiae (broken blood vessels in the eyes), bruising, redness, or voice changes does not prove strangulation did not occur — but defense attorneys use that absence strategically in cross-examination and in challenging the State’s expert testimony.
Challenging Intent — Knowingly vs. Recklessly
The first subsection of § 565.073 requires the defendant to have knowingly caused physical injury. Reckless conduct that results in physical injury is covered by fourth-degree domestic assault (§ 565.076), not second-degree. Defense attorneys challenge whether the evidence establishes the required knowing mental state or whether the conduct was reckless — a distinction that can mean the difference between a Class D Felony and a Class A Misdemeanor.
Self-Defense
Missouri’s self-defense law under § 563.031 applies in domestic situations.¹⁰ A person who acts in response to an aggressor — including a domestic partner who initiated the confrontation — has a complete legal defense if the force used was reasonable and proportionate to the threat. Defense attorneys investigate who the initial aggressor was, what force was used, and whether the defendant’s response was reasonable under the circumstances.
Challenging the Domestic Victim Classification
Not every relationship qualifies as a domestic victim relationship. Defense attorneys examine whether the alleged victim actually falls within the categories defined under § 455.010 and § 565.002. If the relationship does not qualify, the appropriate charge is general assault, which, while serious, does not carry the same collateral consequences as a domestic assault conviction.
Negotiating to a Non-DV Disposition
When a complete defense is not viable, negotiating a resolution that avoids a domestic-violence-specific conviction can preserve firearm rights and reduce collateral consequences. A general assault conviction at the same class level — or a peace disturbance — does not trigger the federal domestic violence firearm prohibition or the permanent no-expungement rule. This distinction matters enormously for clients who own firearms, work in regulated fields, or have immigration concerns.
