HOMICIDE DEFENSE

A homicide charge is the most serious accusation Arizona law can make against a person, and it is the one where the gap between what actually happened and what gets charged is often widest. Police make a charging recommendation in the first hours, based on incomplete information, and the case gets built around it from there.

Arizona recognizes four homicide offenses, and they are not four degrees of the same thing. They are four different mental states applied to the same result. Which one the State can actually prove is, in most cases, the entire fight.

Premeditation is narrower than most people think

The line between first and second degree murder in Arizona is premeditation, and A.R.S. § 13-1101 defines it carefully. A person acts with premeditation when the intention or knowledge that he will kill precedes the killing by any length of time to permit reflection. The statute then says two things that matter a great deal to the defense.

First, proof of actual reflection is not required. Second — and this is the sentence that decides cases — an act is not done with premeditation if it is the instant effect of a sudden quarrel or heat of passion.

That is not a technicality. Arizona courts have repeatedly grappled with how much time is enough, and prosecutors often charge first degree murder on facts that show a fight escalating in seconds. Whether the State can prove premeditation, rather than assert it, is the difference between a class 1 felony carrying natural life or death and a class 1 felony carrying a term of years, or a class 2 manslaughter.

Felony murder

Arizona’s felony murder rule is the part of § 13-1105 that surprises people most. If a death occurs in the course of and in furtherance of an enumerated felony — among them armed robbery, burglary, arson, kidnapping, drive-by shooting, escape, certain drug offenses, child abuse, and unlawful flight from a pursuing law enforcement vehicle — every participant can be charged with first degree murder. The statute is explicit that this form of the offense “requires no specific mental state other than what is required for the commission of any of the enumerated felonies.”

In practical terms: a person who drove to a robbery and never went inside, and never intended for anyone to be hurt, can face the same charge as the person who fired. Defending a felony murder allegation means attacking the predicate felony, the “in the course of and in furtherance of” connection, and the scope of the individual’s participation — not arguing about intent to kill, which the statute does not require.

What each charge actually carries

First degree murder is punishable by death or natural life for an adult defendant. A person sentenced to natural life is not eligible for commutation, parole, work furlough, work release, or release on any basis. Where a life sentence rather than natural life is imposed, A.R.S. § 13-751 bars release until twenty-five calendar years have been served, or thirty-five years if the person killed was under fifteen or was an unborn child.

Second degree murder is sentenced under its own statute, A.R.S. § 13-710, rather than the ordinary felony ranges.

Manslaughter and negligent homicide are almost always alleged as dangerous offenses, because a death caused by a firearm or a vehicle involves a deadly weapon or dangerous instrument. That allegation, under A.R.S. § 13-704, removes probation from the table and sets the ranges above. Whether the dangerousness allegation sticks is itself worth litigating.

Where the person killed was under fifteen, a second degree murder charge is sentenced under § 13-705 as a dangerous crime against children, which carries a range of twenty-five to thirty-five years with a presumptive term of thirty, or life.

Self-defense in Arizona, and who has to prove it

Arizona’s justification statutes are more favorable to the accused than most people realize, and one procedural rule matters more than all the others.

Under A.R.S. § 13-205, justification defenses are not affirmative defenses. That means the burden never shifts to you. Once evidence of justification is presented, the State must prove beyond a reasonable doubt that you did not act with justification. You are not required to prove you acted in self-defense; the State is required to disprove it, to the highest standard the law has.

Deadly physical force is justified under A.R.S. § 13-405 when a person would be justified in using ordinary physical force and reasonably believes deadly physical force is immediately necessary to protect against another’s use or attempted use of unlawful deadly physical force. And Arizona imposes no duty to retreat: a person who is somewhere he may lawfully be, and is not engaged in an unlawful act, may stand his ground.

These rules do real work in real cases. A homicide that police charged as second degree murder on the night it happened can be a justified use of force once the full picture — prior threats, the other person’s conduct, the physical layout of the scene — is developed and put in front of a jury.

How a homicide case moves through Maricopa County

Homicide cases in the Phoenix metro are prosecuted by the Maricopa County Attorney’s Office and heard in the Maricopa County Superior Court. Most begin with a grand jury indictment rather than a preliminary hearing, which means the first formal charging decision is made in a proceeding the defense does not attend and cannot cross-examine in. That is worth understanding early, because it explains how a case can be charged at first degree murder on evidence that looks very different once disclosure arrives.

After arraignment comes disclosure, which in a homicide case is enormous: scene photographs and video, autopsy and toxicology reports, digital extractions, recorded interviews of every witness, and jail calls. Then come the motions that shape the trial — motions to suppress statements and searches, motions about which expert opinions the jury will hear, and motions about what evidence of the deceased person’s conduct the defense is allowed to present in a self-defense case. Trial, if the case goes there, is usually two years or more from arrest.

Release is decided early and is frequently contested. Arizona law permits holding a person without bond in capital cases and in certain other circumstances, and the initial release decision is often made before the defense has seen anything. It can be revisited as the picture changes, and in a case where the State’s theory weakens, it should be.

Vehicular homicide deserves a note of its own. A death caused in a collision is generally charged in Arizona as manslaughter or negligent homicide rather than under a separate vehicular statute, and where impairment is alleged, a second degree murder charge on an extreme indifference theory is possible. Those cases combine homicide defense with accident reconstruction and with the same blood-draw and testing issues that arise in DUI defense, and they need to be worked on both fronts at once.

How homicide cases are defended

There is no single defense to a homicide charge. There are, in most cases, several arguments running at once, and the work is deciding which ones a jury will actually accept together.

Reducing the charge. Most homicide defense is not “someone else did it.” It is the argument that the State charged too high — that what it calls premeditation was a sudden quarrel, that what it calls extreme indifference was ordinary recklessness, that what it calls recklessness was criminal negligence or no crime at all. Each step down is measured in decades.

Justification. Self-defense, defense of a third person, defense of premises, and the crime prevention statute all apply to homicide cases, and the State carries the burden of disproving them beyond a reasonable doubt.

Causation. The State has to prove that the defendant’s conduct caused the death. Intervening medical treatment, pre-existing conditions, and multiple actors all complicate that chain, and it is a chain that has to be proven, not assumed.

Identity and participation. In shootings with multiple people present and in felony murder allegations, who did what is frequently disputed and frequently supported by nothing more solid than a co-defendant with a reason to talk.

The forensic case. Firearms and toolmark comparison, bloodstain pattern interpretation, time-of-death estimates, and DNA mixture analysis are all areas where the confidence expressed in a police report exceeds what the underlying science supports. These cases warrant independent experts, and Arizona courts have mechanisms for appointing them.

How statements were obtained. Homicide interrogations are long, and they happen when a person is exhausted and frightened. Whether an interview was custodial, whether Miranda warnings were given and understood, and whether a request for counsel was honored are threshold questions in almost every one of these cases.

What to do if you are under investigation

Do not give a statement. This is true even — especially — if you believe you acted in self-defense. Self-defense is a legal conclusion built from facts, and the version of events you give while adrenaline is still running, without a lawyer, becomes the version you are locked into for the next two years. Detectives are not required to be accurate about what evidence they have.

Do not consent to searches of your home, vehicle, or phone. Do not discuss the case with anyone other than your attorney, including family, and understand that every call from jail is recorded and routinely played at trial. Preserve everything: clothing, messages, photographs, the names of anyone who saw any part of what happened. Witnesses become unreachable quickly, and an investigator sent out in the first week finds people that an investigator sent out in the sixth month cannot.

Common questions

What is the difference between murder and manslaughter in Arizona? The mental state. Second degree murder requires intent, knowledge that the conduct will cause death or serious physical injury, or extreme indifference to human life. Manslaughter covers reckless killings, and it also covers what would otherwise be second degree murder when it was committed on a sudden quarrel or in the heat of passion resulting from adequate provocation. Adequate provocation is defined by statute as conduct or circumstances sufficient to deprive a reasonable person of self-control.

Can I be charged with murder if I did not kill anyone? Yes. Under Arizona’s felony murder rule, a death that occurs during and in furtherance of certain felonies exposes every participant to a first degree murder charge, without any requirement that the person intended or anticipated a death.

Does Arizona still have the death penalty? Yes. First degree murder is punishable by death or natural life for an adult defendant. Whether the State seeks death is a discretionary charging decision, and it is one that can be engaged with early — before it is made.

Is there a time limit on filing homicide charges? No. Homicide has no statute of limitations in Arizona, which is why cold case charges are filed decades after the fact.

How long does a homicide case take? Capital and first degree murder cases in Maricopa County routinely take two years or more. That is difficult to live through, and it is also time in which a defense is built.

No lawyer can promise you an outcome in a case like this, and you should not trust one who tries. What we can do is tell you honestly what the State must prove, where its case is weak, and what the realistic range of outcomes is — before you make any decision that cannot be undone.
