Rule of Law:
Under the Sixth Amendment, once a jury finds beyond a reasonable doubt (or a defendant admits to) a single aggravating factor, a sentencing judge is permitted to find and consider additional aggravating factors by a preponderance of the evidence when imposing a sentence within the authorized aggravated range.
Facts:
- Pablo Areiniega Martinez was the tenant of a 69-year-old landlord.
- Martinez, with an accomplice, participated in the brutal killing of his landlord.
- During the commission of the crime, a knife was used as a weapon.
- Martinez also committed burglary at the property.
- Following the other crimes, Martinez committed theft of a means of transportation.
Procedural Posture:
- A jury in a state trial court convicted Pablo Areiniega Martinez of first-degree murder, burglary, and theft.
- For the burglary and theft convictions, the trial judge found eight aggravating factors and imposed consecutive aggravated sentences of seven years each.
- Martinez, as appellant, appealed his sentences to the Arizona Court of Appeals (an intermediate appellate court).
- The Court of Appeals affirmed the sentences, holding that the jury's murder verdict implicitly found one aggravating factor, which was sufficient to make Martinez eligible for an aggravated sentence.
- Martinez, as petitioner, petitioned for review by the Arizona Supreme Court (the state's highest court), which granted review to resolve the issue.

Issue:
Does the Sixth Amendment right to a jury trial require a jury to find every aggravating factor that a judge considers when imposing a sentence within an aggravated sentencing range?
Opinions:
Majority - McGregor, C.J.
No. The Sixth Amendment does not require a jury to find every aggravating factor a judge relies upon for sentencing. Once a jury finds a single aggravating factor, it establishes the facts legally essential to expose the defendant to the maximum sentence in the aggravated range, and the judge may then exercise discretion to find additional factors to determine the specific sentence within that range. The Supreme Court's jurisprudence, particularly in Apprendi, Blakely, and Booker, distinguishes between facts that increase the statutory maximum penalty, which must be found by a jury, and facts that guide a judge's discretion within an already-authorized sentencing range. Here, the jury's first-degree murder verdict implicitly found the aggravating factor of causing the victim's death. This single, jury-found fact was sufficient to raise the statutory maximum for Martinez's burglary and theft convictions to the top of the aggravated range, thereby allowing the judge to consider other aggravating factors without violating the Sixth Amendment.
Analysis:
This case clarifies the application of Blakely v. Washington to Arizona's non-capital sentencing scheme, establishing the 'single aggravator' rule. It solidifies the principle that the jury's role is to find the facts that make a defendant eligible for a higher sentencing range, but once that eligibility is established, the judge retains traditional discretion to select a sentence within that range. This decision preserves a significant degree of judicial fact-finding in sentencing, preventing the Sixth Amendment from requiring a full-blown jury trial on every potential sentencing factor. It creates a clear demarcation between facts that are 'legally essential' to increase the maximum punishment and those that merely guide sentencing discretion.
