Under Arizona law, the crime of arson is well-defined, and the severity of the charges can vary based on the specific situation.

Understanding the Legal Definition of Arson

In simple terms, arson means intentionally knowingly, and unlawfully setting fire to something or causing an explosion. Under ARS 13-1703, the intent plays a vital role in defining the crime. If a person knowingly damages a structure or property by using fire or explosion, they could be charged with arson.


Categories of Arson: Arson of a Structure, Arson of Property, and Arson of an Occupied Structure

Arson charges in Arizona are divided into different categories, which are:

  • Arson of a Structure: This includes setting fire to buildings, whether occupied or unoccupied.
  • Arson of Property: This covers the intentional burning of personal property, such as a car or a fence.
  • Arson of an Occupied Structure: This is considered the most severe form of arson. It involves setting fire to a building or structure that is occupied by people.


Different Degrees of Severity and Their Implications

The seriousness of an arson charge depends on the details of the case. Here are the degrees of severity:

  • Reckless Burning: When a person recklessly causes a fire, it is a less severe charge but still punishable by law.
  • Arson of a Structure or Property: This is more serious and can lead to significant penalties if found guilty.
  • Arson of an Occupied Structure: As mentioned earlier, this is the most severe type of arson and carries the harshest penalties.

Fire investigation on accusations of arson

Investigating Arson of an Occupied Structure in Arizona

Investigating arson charges is a meticulous and complex process. It involves gathering evidence, analyzing the scene, and determining the cause of the fire. In Arizona, the process is guided by specific procedures and requires the collaboration of law enforcement, fire investigators, and forensic experts.


Here's an in-depth look into the different stages of investigating arson charges:


The Process of Investigating Arson, Including the Role of Law Enforcement and Fire Investigators

  • Initial Response: Police and fire departments respond to the fire incident, and once the fire is controlled, an assessment of the scene begins.
  • Fire Investigators: Skilled investigators specializing in arson conduct a thorough examination of the scene. They determine the origin and cause of the fire, looking for signs of intentional acts.
  • Collaboration: Arson investigations often involve collaboration between local law enforcement, state agencies, and even federal authorities such as the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

Collection of Evidence, Forensic Analysis, and Expert Testimony

  • Collecting Evidence: This includes taking photographs, gathering physical evidence, and interviewing witnesses. The evidence must be handled and preserved properly to be admissible in court.
  • Forensic Analysis: Labs analyze samples from the fire scene, such as residues and burned materials, to detect the presence of accelerants or other clues.
  • Expert Testimony: Experts in fire investigation may be called to testify in court, explaining the findings and supporting the prosecution or defense.

Challenges and Common Mistakes in the Investigation

  • Preserving the Scene: The fire's destructive nature can make evidence preservation challenging, and mistakes can lead to critical evidence being overlooked or contaminated.
  • Interpreting Fire Patterns: Misinterpreting the signs and patterns of a fire can lead to incorrect conclusions about the fire's origin and cause.
  • Legal Considerations: Investigators must follow legal procedures, such as obtaining proper search warrants, to ensure that the evidence collected can be used in court.

Investigating arson charges in Arizona requires specialized knowledge, expertise, and attention to detail. The process is governed by both state and federal laws, making collaboration between various agencies essential.


The quality of the investigation can significantly influence the outcome of an arson case. For individuals facing felony arson charges, understanding the investigative process can be critical, and having an experienced Phoenix arson defense attorney who is familiar with the intricacies of arson investigations under ARS 13-1703 can make a significant difference in the case's resolution.

Defending against arson charges with a Phoenix arson defense attorney

Defending Against Arson Charges - Structure or Property

Defending against arson charges is a multifaceted and intricate task that requires thorough legal expertise. A robust defense strategy can mean the difference between a conviction and an acquittal.


This section will explore the legal defenses that may be available, the role of a skilled Phoenix arson defense lawyer, and the strategies for challenging the prosecution's case under Arizona law.

  • Proving Lack of Intent

    Arguing that the fire was accidental and not intentional.

  • Insufficient Evidence

    Challenging the evidence collected by the prosecution, including the methods used in the investigation.

  • Alibi

    Providing evidence that the accused was not at the scene of the crime when the fire occurred.

  • Mistaken Identity

    Asserting that the wrong person has been charged.

  • False Accusation

    Sometimes, personal grudges or misunderstandings may lead to a false accusation of arson. Proving that the accusation is false or motivated by malice can be a strong defense.

  • Faulty Forensic Analysis

    If there was an error or bias in the forensic analysis of the fire's origin and cause, challenging the scientific methods and conclusions can form a substantial part of the defense.

  • Violation of Constitutional Rights

    If law enforcement violated the defendant's constitutional rights during the investigation, such as conducting an illegal search and seizure, the evidence obtained may be suppressed, weakening the prosecution's case.

  • Entrapment

    This defense could be used if the defendant was coerced or induced by law enforcement to commit the arson act, and they would not have committed it otherwise.

  • Mental Incapacity

    If the defendant was suffering from a mental disorder at the time of the alleged arson, they may not be held legally responsible. This defense would require substantial medical evidence and expert testimony.

The Role of a Skilled Criminal Defense Attorney

Having an experienced criminal defense attorney is vital for a successful defense against arson charges. Here's why:

  • Understanding of ARS 13-1703: A Phoenix arson attorney with expertise in Arizona's laws can navigate the complex legal landscape.
  • Strategic Planning: A defense attorney will craft a customized defense strategy, carefully considering the unique aspects of the case.
  • Negotiating with Prosecutors: An adept attorney can negotiate plea deals or lesser charges when appropriate, depending on the case's strength and evidence.

Strategies and Tactics for Challenging the Prosecution's Case

The defense may employ various tactics to challenge the prosecution's case, such as:

  • Questioning the Investigation: This can involve challenging the methods used by investigators, the preservation of evidence, or the qualifications of expert witnesses.
  • Presenting Alternative Theories: The defense may introduce other plausible explanations for the fire, undermining the prosecution's theory.
  • Utilizing Expert Witnesses: Defense experts can analyze the fire's origin and cause, potentially contradicting the prosecution's findings.

Defending against arson charges in Arizona requires a comprehensive understanding of the legal processes, the evidence, and the strategies that can be employed to challenge the charges effectively. It emphasizes the importance of hiring a criminal defense attorney who specializes in arson cases and is well-versed in the complexity of ARS 13-1703.
