When facing serious criminal charges, understanding the law is critical. In Arizona, first-degree murder is the most severe homicide offense and carries life-altering consequences, including life imprisonment or even the death penalty.
If you're researching first degree murder Arizona laws or trying to understand how they differ from Arizona second degree murder, this guide breaks it down in a clear, practical way.
What Is First-Degree Murder in Arizona?
Under Arizona law (ARS § 13-1105), first-degree murder is defined as the intentional or knowing killing of another person under specific circumstances.
What makes this charge different from other homicide offenses is the presence of premeditation, involvement in certain felonies, or the killing of a protected individual such as a police officer.
Arizona law recognizes three distinct types of first-degree murder, each with unique legal elements.
1. Premeditated Murder
What It Means
Premeditated murder occurs when a person intentionally plans and carries out a killing. The key factor here is premeditation, meaning the individual had time—even briefly—to think about the act before committing it.
Contrary to popular belief, premeditation doesn’t require weeks or months of planning. Even a few seconds of reflection can qualify under Arizona law.
Key Elements
- Intent to kill or knowledge that actions will cause death
- Some level of planning or reflection before the act
- The act was not done in the “heat of passion”
Example
A person waits outside someone’s home with a weapon and attacks them when they arrive. This demonstrates intent and planning, making it premeditated murder.
Why It Matters
This is the most straightforward form of first degree murder Arizona, and prosecutors often rely on evidence such as:
- Text messages or threats
- Surveillance footage
- Witness testimony
2. Felony Murder
What It Means
Felony murder is unique because it does not require intent to kill. Instead, it applies when someone dies during the commission of certain serious crimes.
Even if the death was accidental, participants in the felony can still be charged with first-degree murder.
Common Felonies That Trigger This Rule
Arizona law includes several underlying crimes, such as:
- Robbery
- Kidnapping
- Burglary
- Arson
- Sexual assault
- Drug trafficking
- Child abuse
If someone dies during or while fleeing from these crimes, the felony murder rule applies.
Key Elements
- Participation in a qualifying felony
- A death occurs during or immediately after the crime
- No requirement to prove intent to kill
Example
If two individuals commit a robbery and a victim dies during the incident—even unintentionally—both can face first-degree murder charges.
Why It Matters
This is one of the most controversial aspects of first degree murder Arizona law because:
- You can be charged even if you didn’t cause the death
- Intent is not required
- All participants may be held equally responsible
3. Murder of a Law Enforcement Officer
What It Means
The third category involves the intentional killing of a law enforcement officer performing official duties.
This type of first-degree murder is treated with heightened severity due to the victim’s role in public safety.
Key Elements
- The victim is a law enforcement officer
- The officer was on duty
- The killing was intentional or knowing
Example
If someone intentionally shoots a police officer during a traffic stop or pursuit, it qualifies under this category.
Why It Matters
This charge often carries the harshest penalties, including:
- Life imprisonment without parole
- Potential death penalty

Challenging whether the accused was actually involved.
