Everything you say can be used against you.
Evidence disappears. Witnesses’ memories fade. The prosecution starts building its case the moment of your arrest.
In murder and violent crime cases, Maricopa County prosecutors move aggressively from the very first hours. The earlier we are involved, the more options we have to protect your rights — including preserving your own witnesses and challenging early forensic conclusions before they harden into the prosecution’s theory.
First-degree murder: death penalty or life imprisonment — with or without the possibility of release after 25 years
Second-degree murder: Class 1 felony — 10 to 25 years in prison with no probation
Manslaughter: Class 2 dangerous felony — minimum 7 years, up to 35 years for repeat dangerous offenders
Felony murder applies even if you didn’t cause the death — all participants in a qualifying felony can be charged
Dangerous offense classification means mandatory prison — no suspended sentence, no probation
Permanent loss of voting rights, firearm rights, and most professional licensing eligibility
Maricopa County prosecutors are known for pursuing the maximum charge and the maximum sentence in violent crime cases

Common Defense Strategies for Murder & Violent Crime Charges
Self-Defense or Defense of Others (A.R.S. § 13-404 / 13-406)
Arizona law permits the use of physical force — including deadly force in certain circumstances — to protect yourself or another from imminent harm. We build self-defense arguments backed by witness statements, medical evidence, surveillance footage, and physical evidence that demonstrates the force used was legally justified and necessary.
Challenging the Felony Murder Rule
Arizona’s felony murder rule can charge you with first-degree murder for participating in a qualifying felony during which someone died — even if you didn’t cause the death. We challenge whether the underlying felony was actually committed, whether the death was a foreseeable consequence, and whether your level of participation meets the legal threshold for liability.
Lack of Intent or Premeditation
First-degree murder requires proof of deliberate premeditation. If the state cannot prove the killing was planned and intentional, the charge may not hold. We present evidence of accident, sudden emotional disturbance, or circumstances inconsistent with premeditation to contest the degree of the charge and fight for a lesser classification.
Guilty Except Insane (A.R.S. § 13-502)
If a mental disorder at the time of the crime prevented you from knowing your conduct was wrong, Arizona law provides this affirmative defense. It doesn’t excuse the act, but it can significantly alter the outcome — directing the case toward treatment rather than traditional prison sentencing.
Witness Credibility & False Allegations
Many violent crime cases rest on a single witness or co-defendant testimony offered in exchange for a deal. We investigate prior statements, inconsistencies, motives to fabricate, and the reliability of eyewitness identification — which is notoriously fallible, particularly in high-stress situations with poor lighting or obstructed views.
