1st Degree Murder Arizona

1st Degree Arizona Murder Charges - HOMICIDE

The crime of 1st degree Arizona homicide murder is defined by ARS 13-1105 and is divided into three main categories. 

Types of First-Degree Murder

  •  Premeditated Murder means you intended to kill or knew your actions would cause death and that this intent or knowledge was understood and considered before the killing. An act is not premeditated if it’s the result of a sudden fight or strong emotions. The time for reflection doesn’t have to be long. The gap between wanting to kill and actually killing can be very short. The key is that there was some thought before the killing.
  • Felony Murder occurs when someone dies during the commission of another serious crime, known as a felony. This type of 1st degree murder does not require premeditation or direct intent to kill. If a death occurs while you or someone you are with is committing or running from a crime like burglary, robbery, or certain sex or drug crimes, you can be charged. It is important to know that you don’t have to be the one who caused the death. Anyone involved in the felony can be charged if someone dies during its commission.
  • Murder of a Law Enforcement Officer occurs if you knowingly and intentionally kill a police officer while they are on duty. Unlike premeditated murder, this charge does not require the prosecution to prove that the killing was planned in advance. 

2nd Degree Murder in Arizona

2nd Degree Arizona Murder Charges - HOMICIDE​

2nd degree murder in Arizona is defined in ARS 13-1104 and involves causing someone’s death without premeditation. ARS 13-1104 outlines three categories of 2nd degree murder in Arizona.

Types of Second-Degree Murder

  •  Intentional Causation of Death involves intentionally killing someone but without any prior planning. For example, intentionally killing someone during a fight that the victim didn’t start is 2nd degree murder. The intent to kill is the key part of this Arizona murder charge.
  • Knowing Conduct Leading to Death or Serious Injury involves actions known to cause death or serious physical injury. You could be charged with 2nd degree murder in Arizona if you knew your actions could very likely cause death or serious physical injury, and a death occurred. In other words, you might not have intended to kill, but you were aware your conduct was so dangerous that death was a possible result. 
  • Extreme Indifference to Human Life involves reckless behavior that shows a complete disregard for human life and creates a grave risk of death. The actions are so dangerous that death is an unsurprising outcome. This must be a major departure from how a reasonable person would act in the same situation. 

Manslaughter Arizona

Manslaughter Arizona Murder Charges - HOMICIDE​

Manslaughter Arizona homicide charges are different from other murder charges because manslaughter generally involves recklessness or the heat of passion rather than an intentional killing. ARS 13-1103 outlines five categories of manslaughter Arizona charges. 

Types of Manslaughter

  • Reckless Manslaughter occurs if you recklessly cause another person’s death. Recklessness means you were aware of a serious and unjustifiable risk but chose to disregard it, and this disregard was a major deviation from how a reasonable person would act. Voluntary intoxication is not an excuse. It is reckless if you create an unjustifiable risk but are unaware of it because of voluntary intoxication. 
  • Heat of Passion Manslaughter involves killing someone intentionally during a sudden fight, provoked by the victim. The key element is “adequate provocation,” which means a level of provocation that would trigger a loss of self-control in a reasonable person. Mere words are generally not enough. 
  • Aiding a Suicide involves intentionally providing the means for another person to commit suicide, knowing that the person is suicidal. This could mean supplying the necessary tools, medications, or other means to accomplish the suicide. 
  • Manslaughter by Coercion is a rare situation and occurs if you kill someone because a third party threatened you with immediate deadly force. The threat must be so severe that a reasonable person would not have been able to resist. 
  • Manslaughter of an Unborn Child involves knowingly or recklessly causing the death of an unborn child by physically injuring the mother. 

Negligent Homicide Arizona

Negligent Arizona homicide involves causing a death through criminal negligence rather than intentionally or recklessly killing another. In practice, it means you failed to see a substantial and unjustifiable risk that a reasonable person would have seen. According to ARS 13-1102, this is an unintentional killing that happens because of a lack of care, not because of an intent to harm.

Elements of Negligent Homicide

  1. A Death Occurred: Your actions resulted in the death of another person, which can include an unborn child. 
  2. Criminal Negligence: You failed to recognize a serious risk of death, acting in a way that was a major departure from reasonable behavior. 
  3. Causation: Your negligent act directly caused the death.
