A life sentence in Arizona runs one of two ways. “Natural life” means the rest of the person’s life in prison with no possibility of release, ever. A “life” sentence with a minimum term means at least 25 or 35 calendar years behind bars before the person can even apply for release, with no guarantee it will be granted. Which version applies turns on the crime, the ages involved, and whether the offense happened before or after January 1, 1994.
Natural Life Means No Release
Natural life is the harshest penalty Arizona imposes short of death. A person sentenced to natural life is not eligible for commutation, parole, work furlough, work release, or release on any other basis for the rest of their life.1Arizona Legislature. Arizona Code 13-751 – Sentence of Death or Life Imprisonment Aggravating and Mitigating Circumstances Definition No hearing, no application, no path out.
Natural life is mandatory for adult defendants (18 or older when the crime occurred) convicted of premeditated first-degree murder when the state sought the death penalty and the jury or judge chose imprisonment instead.1Arizona Legislature. Arizona Code 13-751 – Sentence of Death or Life Imprisonment Aggravating and Mitigating Circumstances Definition It also applies to certain repeat offenders convicted of dangerous crimes against children, including commercial sexual exploitation of a minor and child sex trafficking where the defendant has a prior conviction for a dangerous crime against children in the first degree.2Arizona Legislature. Arizona Code 13-705 – Dangerous Crimes Against Children Sentencing
For defendants under 18 at the time of a first-degree murder, the court chooses between natural life and life with a minimum term, and the same choice applies in felony murder cases regardless of the defendant’s age.3Arizona Legislature. Arizona Code 13-752 – Sentences of Death Life Imprisonment or Natural Life
Life With a Minimum of 25 or 35 Calendar Years
When the court imposes life rather than natural life for first-degree murder, the minimum time before release eligibility depends on the victim’s age:
- 25 calendar years if the victim was 15 or older at the time of the offense.
- 35 calendar years if the victim was under 15 or was an unborn child.1Arizona Legislature. Arizona Code 13-751 – Sentence of Death or Life Imprisonment Aggravating and Mitigating Circumstances Definition
Calendar years mean exactly that. Good-behavior credits do not shorten the clock. A person serving a 25-year minimum will serve at least 25 actual years before becoming eligible to apply for release, and reaching the minimum guarantees only the right to start the process.
Other Crimes That Carry Life
First-degree murder is not the only route to a life sentence. Under the dangerous-crimes-against-children statute, an adult convicted of sexually assaulting or engaging in sexual conduct with a child 12 or younger must be sentenced to life with a 35-year minimum before release eligibility.2Arizona Legislature. Arizona Code 13-705 – Dangerous Crimes Against Children Sentencing The same 35-year minimum applies to attempted first-degree murder of a child under 12 and to second-degree murder of a child under 15. A sexual assault involving the intentional infliction of serious physical injury can result in life with a 25-year minimum regardless of the victim’s age.4Arizona Legislature. Arizona Code 13-1406 – Sexual Assault Classification Increased Punishment
The January 1, 1994 Divide
Arizona’s truth-in-sentencing law eliminated traditional parole for crimes committed on or after January 1, 1994. That single date determines how a life-sentenced inmate can seek release once the minimum is served.
Offenses Before 1994
Inmates whose offenses occurred between October 1, 1978 and December 31, 1993 generally become eligible for parole after serving the minimum term.5Arizona Department of Corrections. DO 1002 – Inmate Release Eligibility System The Arizona Board of Executive Clemency can grant parole directly, without the Governor.
Offenses On or After 1994
For post-1994 crimes, parole does not exist. The only route to release before death is commutation of sentence. The Board of Executive Clemency can only recommend commutation to the Governor after finding, by clear and convincing evidence, that the sentence is clearly excessive given the nature of the offense and the offender’s record, and that there is a substantial probability the person will follow the law if released.6Arizona Legislature. Arizona Code 31-402 – Powers of Board Powers and Duties of Governor Powers and Duties of Executive Director Even a favorable Board recommendation can be denied by the Governor.
What Happens at the Minimum
Reaching the minimum term triggers an application process, not an automatic release. For post-1994 commutation requests, the Board uses a two-phase hearing system.7Arizona Board of Executive Clemency. Board Policy 114 – Commutation of Sentence Phase I is a paper review without the applicant; a majority vote is needed to advance. Phase II is a full hearing where the applicant participates and victims, the county attorney, the presiding judge, and the public can be heard.6Arizona Legislature. Arizona Code 31-402 – Powers of Board Powers and Duties of Governor Powers and Duties of Executive Director Most applications end at Phase I. The Board weighs institutional behavior, rehabilitation, the severity of the original crime, victim opposition, and the risk the person would pose if released.
For pre-1994 inmates eligible for parole, the Board holds a parole hearing once the minimum term is met and can grant release on its own authority.
Juvenile Offenders
After the U.S. Supreme Court’s decision in Miller v. Alabama, Arizona created a parole pathway for anyone sentenced to life with a minimum term for an offense committed before they turned 18. These individuals become eligible for parole once they complete the minimum sentence, even if the crime occurred after the 1994 cutoff. If parole is granted, it lasts for life and can be revoked for any violation.8Arizona Legislature. Arizona Code 13-716 – Juvenile Offenders Sentenced to Life Imprisonment Parole Eligibility
When a Plea Agreement Sets a Different Minimum
The 25- and 35-year minimums are the statutory defaults. When a first-degree murder case is resolved through a plea agreement that stipulates a specific parole eligibility date, that negotiated number controls instead.9Arizona Legislature. Arizona Code 13-718 – Sentence of Life Imprisonment Parole Eligibility Applicability A plea-negotiated life sentence with a parole stipulation is treated as genuine parole eligibility, so the Board conducts a parole hearing rather than the two-phase commutation process. Release is still not guaranteed, but the path is shorter and the decision does not require the Governor’s signature.
