Battery by strangulation is a felony in most states and under federal law, defined as intentionally, knowingly, or recklessly impeding another person’s breathing or blood circulation by applying pressure to the throat or neck. When the victim is a spouse, intimate partner, or dating partner, federal law authorizes up to 10 years in prison.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction The charge does not require any visible injury on the victim, which is one of the features that separates it from ordinary assault or battery.
How the Law Defines the Offense
The federal definition in 18 U.S.C. ยง 113 is the clearest statement of what “strangling” means: impeding someone’s normal breathing or blood circulation by pressing on their throat or neck. It applies regardless of whether the conduct leaves any visible mark and regardless of whether the person intended to kill or seriously injure the victim.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction
State definitions vary in wording but track the same core elements. A prosecutor generally has to prove three things: that the defendant applied pressure to the victim’s neck or throat, that the pressure was capable of restricting breathing or blood flow, and that the defendant acted intentionally, knowingly, or recklessly.
The mental state requirement is where many defendants misunderstand their exposure. There is no need to show that the person planned the act or intended to kill. Recklessness is enough, meaning the person was aware their conduct created a serious risk and disregarded it. Grabbing someone by the throat during a heated argument, with no deliberate plan to cut off air, can satisfy that standard.
Penalties You Can Face
Under federal law, strangulation of a spouse, intimate partner, or dating partner carries up to 10 years in prison, a fine, or both.1Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction Federal jurisdiction applies on military bases, tribal lands, national parks, and other federal territory. The federal sentencing guidelines also add a three-level enhancement for strangulation in aggravated assault cases involving intimate partners.2United States Sentencing Commission. USSC Amendment 781
State penalties vary but commonly run from two to fifteen years in prison for a first offense, with higher ranges when the victim is a child or pregnant, or when the defendant has prior convictions.
The Firearms Consequence
A conviction reaches well past the sentence. Federal law bars anyone convicted of a misdemeanor crime of domestic violence from possessing firearms or ammunition.3Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Because strangulation charges arise most often in a domestic setting, even a conviction the state treats as a misdemeanor can trigger a permanent federal firearms ban. The ban applies even if the person legally owned firearms before the conviction, and it catches many defendants off guard.
Other Consequences
Depending on the case, a conviction can also bring mandatory participation in a batterer’s intervention program, a protective order barring contact with the victim, loss of custody or visitation rights, and failed background checks for jobs or housing. For noncitizens, a domestic violence conviction can trigger deportation.
Why It’s a Felony Instead of Ordinary Battery
Strangulation can cause unconsciousness in seconds and brain damage within roughly 30 seconds. Brain death is possible within four to five minutes. That narrow window is why legislatures pulled this conduct out of general battery statutes and made it a distinct felony. By 2017, at least 38 states had enacted specific strangulation statutes, and Congress added strangulation of a spouse, intimate partner, or dating partner as a specific federal offense through the Violence Against Women Reauthorization Act of 2013.4Family Justice Center Alliance.

The other reason for the elevated charge is what research has shown about future violence. A study in the Journal of Emergency Medicine found that women whose partners had previously strangled them faced 6.7 times the odds of an attempted homicide, and prior nonfatal strangulation was associated with more than seven-fold odds of becoming a completed homicide victim.5PubMed Central. Non-Fatal Strangulation Is an Important Risk Factor for Homicide of Women Police and prosecutors now treat any report of strangulation as a high-lethality situation, which often triggers mandatory arrest policies even when the victim has no visible injuries.
Prosecution Without Visible Injuries
Most strangulation victims have no marks. A study of cases in San Diego found that officers documented no visible injuries in 62 percent of cases and found only minor marks such as redness or scratches in another 22 percent.6Supreme Court of the United States. The Investigation and Prosecution of Strangulation Cases Historically that meant many cases went uncharged. Today, investigators and forensic nurses build cases around internal symptoms rather than photographs.
Officers trained in strangulation response ask about what the victim felt: lightheadedness, tunnel vision, loss of bladder or bowel control, loss of consciousness. Forensic nurses examine less obvious locations for petechiae, the pinpoint red or purple dots from burst blood vessels, and look for hoarseness, painful swallowing, and tongue swelling. Medical records documenting breathing changes, memory loss, and involuntary urination can carry a case even when a photograph would show nothing.7International Association of Forensic Nurses.

Common Defenses
Defendants in strangulation cases usually raise one or more of the following, with success depending heavily on the facts.
- Lack of intent. Because the statutes require intentional, knowing, or reckless conduct, the defense may argue that any contact with the neck was accidental. This tends to be more plausible in chaotic mutual struggles than in scenarios where evidence or witnesses show deliberate grabbing.
- Self-defense. A defendant may argue they were responding to an imminent physical threat. Evidence of prior threats or violence by the other person can support the claim, but courts examine whether the force used was proportional to the danger.
- Challenging the evidence. Where physical signs exist, the defense may argue that findings like petechiae and bruising are nonspecific and can stem from medication, underlying medical conditions, or unrelated injuries. Strangulation expert testimony often rests on clinical experience rather than quantifiable diagnostic criteria, which opens it to cross-examination.8National Criminal Justice Reference Service.

Consent rarely works. Courts view the argument skeptically in a domestic violence context, and many jurisdictions do not recognize consent as a defense to conduct that risks serious bodily harm.
If You Have Been Strangled
Get a medical evaluation, even if you feel fine and see no marks. Pressure on the neck can cause a carotid artery dissection, where the artery lining tears and blood pools between the layers of the vessel wall. That can throw a clot to the brain and cause a stroke days or weeks later. Research has identified carotid artery dissection as a major cause of stroke in people under 45, accounting for up to 20 percent of strokes in that age group.9ScienceDirect. Fatal and Non-Fatal Bilateral Delayed Carotid Artery Dissection After Manual Strangulation Tell the provider specifically that you were strangled so they look for the right findings, and return immediately if you develop headaches, vision changes, dizziness, or one-sided weakness.
Write down what you can remember: what you felt during the incident, symptoms that appeared afterward, and anything the other person said. The absence of visible marks does not weaken your case. Prosecutors and courts know that most strangulations leave no photograph, and many jurisdictions have specialized resources for strangulation victims, including expedited protective orders and safety planning with trained advocates.
