What Is Aggravated Assault With a Deadly Weapon? ARS 13-1204

What Is Aggravated Assault With a Deadly Weapon Under ARS 13-1204(A)(2)?

Most people charged under this statute never fired a shot and never hurt anyone. They pointed, displayed, or simply held something during an argument , a handgun, a kitchen knife, a bat, a car , and a misdemeanor-level dispute became a mandatory-prison felony. That single fact, the weapon allegation, is what this article is about: what the state must prove, why the legal definition of “deadly weapon” versus “dangerous instrument” is where these cases are won, and what realistically happens to a first-time defendant in Maricopa County.

For the full menu of aggravated assault theories and the statute’s general elements, see our complete guide to aggravated assault under ARS 13-1204. This post goes deep on one subsection: (A)(2), the deadly weapon and dangerous instrument charge.

It is a simple assault plus a weapon. Under ARS 13-1204(A)(2), a person commits aggravated assault if the person commits assault as defined in ARS 13-1203 and “uses a deadly weapon or dangerous instrument.” That means the state must prove two things beyond a reasonable doubt:

• An underlying assault , causing physical injury, intentionally placing someone in reasonable apprehension of imminent physical injury, or touching with intent to injure, insult, or provoke. The apprehension theory matters enormously here: no contact and no injury are required. Pointing a firearm at someone who fears being shot satisfies it. We break down the base offense in our guide to assault with a deadly weapon in Arizona.
• Use of a deadly weapon or dangerous instrument during that assault , not mere possession of one somewhere nearby, but its use in committing the assault.

Note what is not on the list: injury. The (A)(2) theory is separate from 13-1204(A)(1), which covers serious physical injury. Prosecutors often charge both when someone was actually hurt, but an (A)(2) count stands on the weapon alone.

What Counts as a “Deadly Weapon” vs. a “Dangerous Instrument”?

These are two different legal tests, defined in ARS 13-105, and the difference decides real cases:

• Deadly weapon means “anything designed for lethal use, including a firearm.” The test is the object’s design. A gun is a deadly weapon whether or not it was fired and regardless of how it was held.
• Dangerous instrument means anything that “under the circumstances in which it is used, attempted to be used or threatened to be used is readily capable of causing death or serious physical injury.” The test is how the object was actually used , not what it is.

That “as used” language is the defense battleground. A car driven at someone can qualify as a dangerous instrument; the same car idling in the driveway does not. A beer bottle held at your side is a bottle; the state must prove the circumstances of its use made it readily capable of causing death or serious physical injury. Everyday objects , bats, tools, boots, glassware , only become “dangerous instruments” through evidence about how they were wielded, and that evidence can be challenged witness by witness and frame by frame. Knives sit in a middle zone that Arizona prosecutors and defense lawyers fight over constantly; we cover that specific battle in our post on whether a knife is a deadly weapon in an Arizona aggravated assault case.

What Happens on a First Offense of Aggravated Assault With a Deadly Weapon?

This is the question defense lawyers hear most, and the honest answer surprises people: a clean record does not mean probation. Aggravated assault under (A)(2) is a class 3 felony, and because it is charged as a dangerous offense, sentencing comes from ARS 13-704, not the ordinary first-offender ranges. For a first-time dangerous class 3 felony, the range is 5 years minimum, 7.5 years presumptive, 15 years maximum , and 13-704(G) makes a person sentenced under it ineligible for suspension of sentence, probation, pardon, or early release until the sentence is served (aside from narrow statutory exceptions and earned release credits).

Because the mandatory 5-year floor is so severe, the real first-offense fight in Maricopa County usually happens in charging and plea negotiations rather than at sentencing. What defense attorneys commonly see prosecutors trade, when the evidence has problems or mitigation is strong, is the dangerous allegation itself: a plea to aggravated assault as a non-dangerous felony, or to a reduced charge, restores probation eligibility and can turn a mandatory-prison case into a probation-available one. Whether the state offers that depends almost entirely on how much doubt the defense builds around the weapon element, the identification, and the justification evidence , which is why the sections below matter more than the sentencing chart.

What Is the Sentence for Aggravated Assault With a Deadly Weapon in Arizona?

The classification , and therefore the range , moves with who the alleged victim is and with your record. These are the ranges set by ARS 13-1204’s classification subsections and the dangerous-offense tables in ARS 13-704 and ARS 13-705. For a deeper walkthrough of how these numbers are actually applied, see our guide to how many years aggravated assault carries in Arizona.

How Do You Beat an Aggravated Assault With a Deadly Weapon Charge?

You attack the elements the state must prove, one by one. In Arizona courts, the defenses that actually move these cases fall into a handful of categories:

Self-defense and defense of others

Arizona’s justification statutes fit weapon cases naturally. Under ARS 13-404, you may threaten or use physical force when a reasonable person would believe it immediately necessary to protect against another’s unlawful force, and under ARS 13-405, threatening deadly force is justified against the threat of unlawful deadly force , with no duty to retreat if you were somewhere you were legally allowed to be and not acting unlawfully. Many (A)(2) cases are exactly this: someone displayed a firearm to stop an advancing aggressor and got arrested for it. How justification shifts the burden and how it plays out at trial is covered in our dedicated guide to self-defense in Arizona aggravated assault cases.

No assault happened at all

The weapon is irrelevant if the underlying assault fails. On an apprehension theory, the state must prove the alleged victim was actually and reasonably in fear of imminent physical injury , a person who never saw the weapon, or who kept approaching and taunting, undercuts that element. Vague testimony that someone “had a gun” during an argument is not the same as proof it was used to place a specific person in apprehension.

The object was not a deadly weapon or dangerous instrument as used

For non-firearms, the state must prove the “as used” test from ARS 13-105: that the circumstances of use made the object readily capable of causing death or serious physical injury. A thrown phone, a shove with a bottle in hand, a tool held during a shouting match , these routinely get charged as (A)(2) and routinely get knocked down when the actual mechanics of the incident are reconstructed.

Mere presence is not use

The statute punishes a person who “uses” a deadly weapon or dangerous instrument. Being armed while an argument happens is not using the weapon in an assault. Cases built on a holstered or pocketed weapon that was never drawn, displayed, or referenced are vulnerable at every stage, from grand jury to trial.

Victim-category and mental-state challenges

The class 2 escalators require proof that you knew or had reason to know the victim was a first responder or law enforcement employee , plainclothes officers, unmarked vehicles, and chaotic scenes create genuine disputes. And every theory of assault carries a mental state (intentionally, knowingly, or recklessly) that intoxication-fueled, fast-moving incidents often cannot cleanly support.

How Tamou Law Group Defends Aggravated Assault Weapon Charges

Because the dangerous allegation drives everything, our defense starts there. In the first days we move to preserve what disappears fastest: surveillance and doorbell video, 911 audio, bodycam footage, the weapon itself and its chain of custody, and the witnesses whose memories are still fresh. We tell our clients the same thing every time , no statements, no social media, no contact with the alleged victim , because in an apprehension case, your own words are often the only evidence of what the other person “feared.”

From there, the case is fought on the elements: was there an assault at all, was the object a deadly weapon or a dangerous instrument as used, was it “used” rather than merely present, and was the conduct justified under Arizona’s self-defense statutes. Each viable challenge becomes leverage , in grand jury remand motions, in evidentiary challenges, and in negotiations aimed at the outcome that changes everything in these cases: removing the dangerous designation so probation returns to the table.
