When Does an Injury Count as Substantial Bodily Harm in a Washington Assault Case?

In Tacoma, WA assault cases, a broken bone can be enough to support a felony charge because a fracture usually qualifies as substantial bodily harm under state law. But that does not end the analysis. Prosecutors still must prove that the accused caused the injury, and that is often where the real fight happens. In this article, our Tacoma assault defense attorneys explain what courts look at, why medical evidence alone may not decide the case, and what this means for people facing assault charges in Pierce County.

In a recent domestic violence case, the court addressed a critical question that frequently arises in assault prosecutions: when is there enough evidence to prove that a defendant caused serious bodily injury? In State v. Mathis, the defendant challenged whether the State presented sufficient evidence to support a conviction for second-degree assault stemming from an alleged domestic violence incident. The case highlights how courts evaluate conflicting explanations for an injury and reinforces that juries are permitted to draw reasonable inferences from the evidence presented. If you are facing assault charges in Tacoma, it is essential to consult an experienced Tacoma assault attorney to develop an effective defense strategy.

Factual and Procedural Setting

The case arose from an incident in which the alleged victim reported to law enforcement that the defendant, her longtime partner, had assaulted her. Officers were dispatched to a hospital after receiving a report of an assault, where they encountered the defendant in the parking lot and spoke with him about the incident. The defendant indicated that an argument had occurred and suggested that the alleged victim had fallen and injured her arm.

Inside the hospital, however, the alleged victim presented with a fractured arm and described a much more serious and violent encounter. According to her testimony, the altercation began after she returned home from giving a friend a ride. The defendant accused her of infidelity and confronted her on the porch of their home. During the encounter, she ended up on the ground, though she could not definitively recall whether she had fallen or been pushed.

What followed formed the basis of the assault charge. The alleged victim testified that the defendant, who was wearing boots, began kicking her repeatedly while she was on the ground. She attempted to shield herself from the blows by using her arms and hands to block the kicks. After briefly stopping, the defendant instructed her to go inside the residence. Once inside, the violence allegedly continued, with the defendant pushing her into furniture and again kicking her while she was on the floor.

Additional testimony from a third-party witness supported the State’s account of the incident. The witness testified that during a phone call with the alleged victim on the night of the incident, she could hear the victim crying and expressing that she was in significant pain and needed to go to the hospital. The witness also described hearing the defendant yelling in the background, using derogatory language, and initially refusing to take the alleged victim to seek medical treatment.

Medical evidence further established that the alleged victim suffered a fractured arm, which qualifies as substantial bodily harm under Washington law. A treating physician testified that the injury was consistent with being kicked, although the physician acknowledged that it could also have resulted from a fall. This competing explanation became central to the defense’s argument at trial.

The case proceeded to trial, where the jury was tasked with determining whether the State had proven beyond a reasonable doubt that the defendant intentionally assaulted the alleged victim and caused the fracture. The jury ultimately found the defendant guilty of second-degree assault. The defendant then challenged the conviction, arguing that the evidence was insufficient to support the jury’s verdict.

Evidence of a Serious Bodily Injury in Assault Cases

In reviewing the defendant’s challenge, the court applied the well-established standard governing sufficiency of the evidence in criminal cases. Under this standard, the relevant question is whether, when viewing the evidence in the light most favorable to the State, any rational trier of fact could have found the essential elements of the offense beyond a reasonable doubt. This standard is highly deferential to the jury’s role as fact finder.

To establish second degree assault under the applicable statute, the State was required to prove that the defendant intentionally assaulted the alleged victim and caused substantial bodily harm. A fracture is explicitly recognized as substantial bodily harm under Washington law, meaning that the central issue in the case was not the severity of the injury, but rather whether the defendant caused it.

The defendant argued that the State’s case rested on speculation because there were two possible explanations for the injury: the alleged victim could have fractured her arm by falling, or the injury could have resulted from the alleged kicking. According to the defense, the existence of these competing possibilities meant that the jury’s conclusion was based on conjecture rather than proof.

The court rejected this argument, drawing an important distinction between speculation and reasonable inference. While a conviction cannot be based on mere guesswork, the law permits juries to resolve conflicts in the evidence and to draw reasonable conclusions based on the testimony presented. The presence of multiple possible explanations does not automatically render the evidence insufficient, particularly where one explanation is supported by direct testimony and corroborating evidence.

Here, the alleged victim provided direct testimony that the defendant repeatedly kicked her and that those kicks caused her injury. She specifically stated that her fractured arm resulted from the kicks rather than from any fall. The third-party witness’s testimony regarding the defendant’s anger and aggressive behavior during the incident further supported the State’s theory that the assault was violent in nature.

Although the medical testimony acknowledged that the injury could have resulted from a fall, it also confirmed that the fracture was consistent with being kicked. The court emphasized that it is the jury’s role to weigh such competing evidence and determine which explanation is more credible.

The court also noted that when reviewing sufficiency challenges, it must defer to the jury’s determinations regarding witness credibility and the persuasiveness of the evidence. The jury was entitled to believe the alleged victim’s account and to conclude that the defendant’s actions caused the injury.

Ultimately, the court concluded that the evidence, viewed in the light most favorable to the State, was sufficient to support the conviction. A rational jury could find beyond a reasonable doubt that the defendant intentionally assaulted the alleged victim and caused her fractured arm. Accordingly, the court upheld the conviction.

What is Substantial Bodily Harm in Washington?

Under Washington law, substantial bodily harm includes temporary but substantial disfigurement, a temporary but substantial loss or impairment of the function of a body part or organ, or a fracture of any body part. In plain terms, a broken bone can be enough to support a more serious assault charge.

Does a Broken Arm Count as Substantial Bodily Harm?

Yes. A fracture generally qualifies as substantial bodily harm under Washington law. But the prosecution still must prove that the defendant caused the fracture and that the assault charge fits the facts of the case.

Can Someone Be Convicted if There is More Than One Possible Explanation for the Injury?

Potentially, yes. A jury may consider competing explanations and decide which one is more convincing. The existence of another possible cause does not automatically defeat the charge. At the same time, a defense lawyer can argue that the evidence is too uncertain to prove guilt beyond a reasonable doubt.

Is Medical Testimony Always Enough to Prove How an Injury Happened?

No. Medical testimony may help explain whether an injury is consistent with a particular type of force, but it does not always prove exactly how the injury occurred. In many cases, witness credibility, timing, prior statements, and other surrounding facts are just as important.

What is the Difference Between Second-Degree Assault and Fourth-Degree Assault in Washington?

Fourth-degree assault is generally the catch-all misdemeanor assault charge when no higher assault statute applies. Second-degree assault is a felony and usually involves more serious allegations, such as substantial bodily harm, use of a deadly weapon, or other aggravating facts. The difference can have major consequences for jail exposure, felony record concerns, and long-term impact.

What Should You Do if You Are Accused of Assault?

Do not try to explain the situation to police without legal advice. Do not assume the case is minor just because there was no weapon involved. If the alleged victim suffered a fracture or other significant injury, prosecutors may treat the case as a felony. Speak with an experienced Tacoma assault defense attorney as early as possible so your case can be evaluated before important evidence is lost.

Attorney Insight

This case is a good reminder that the seriousness of an injury is only part of the State’s burden in a Washington assault case. A fracture may qualify as substantial bodily harm, but prosecutors still must prove that the accused actually caused that injury. That issue is often more complicated than it first appears.

In many assault prosecutions, especially domestic violence cases, the State may argue that the existence of a serious injury tells the whole story. It does not. The real question is often how the injury happened, when it happened, and whether the available evidence actually supports the prosecution’s theory instead of some other explanation.

At Smith & White, we look closely at causation. We review medical records, witness statements, body-camera footage, 911 recordings, photographs, and the timing of reported pain and treatment. We also examine whether the complaining witness gave a consistent account and whether the physical evidence matches that account. In some cases, the prosecution’s version of events sounds strong at first, but the details leave real doubt about how the injury occurred.

We also know that juries are allowed to draw reasonable inferences from the evidence. That makes early case preparation important. If the State plans to rely on an inference that an injury must have been caused by an alleged assault, the defense needs to be ready to challenge that conclusion with context, inconsistencies, and careful analysis of the facts.

For someone facing assault charges in Tacoma or Pierce County, this issue can make the difference between a weaker misdemeanor allegation and a much more serious felony charge. That is one reason it is important to have a defense lawyer who will do more than simply accept the police report at face value.
