SUPPLEMENTAL OPINION
¶ 1 Our previous opinion affirmed appellant Frank Winfield Anderson’s convictions for conspiracy to commit first degree murder, armed robbery, and three counts of first degree murder.
State v. Anderson,
I.
¶2 The Supreme Court of the United States held in
Apprendi
that “[ojther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.”
¶ 3 Armed robbery is a class 2 felony, Ariz.Rev.Stat. (“A.R.S.”) § 13-1904(B) (1989), which carries a presumptive sentence of five years’ imprisonment, A.R.S. § 13-701(C)(1) (Supp.1995). That presumptive sentence is the “statutory maximum” for a class 2 felony for
Apprendi/Blakely
purposes in the absence of the factual findings required under the applicable statutes to support an aggravated or enhanced sentence.
See State v. Brown (McMullen),
¶ 4 The superior court imposed an aggravated sentence of twelve and one-half years pursuant to A.R.S. § 13-702.01 (Supp. 1995). That statute allows the trial court to “increase the maximum term of imprisonment otherwise authorized” for a class 2 felony up to twenty-three and one-quarter years for a defendant with one historical prior felony conviction “if the court finds that at least two substantial aggravating factors listed in § 13-702, subsection C apply.” A.R.S. § 13-702.01(C). 1 The superior court found six aggravating factors with respect to the armed robbery: (1) infliction of serious physical injury, see § 13-702(0(1); (2) use of a deadly weapon in the commission of the offense, see § 13-702(0(2); (3) presence of an accomplice, see § 13-702(0(4); (4) expec *61 tation of pecuniary gain, see § 13-702(C)(6); (5) conviction of a previous felony, see § 13-702(C)(11); 2 and (6) commission of the offense by ambush, see § 13-702(C)(16). 3
¶ 5 Anderson claims that because none of these aggravating factors was submitted to the jury for determination, his aggravated sentence violates the Sixth Amendment of the United States Constitution as explicated in
Apprendi
and
Blakely.
Anderson did not raise this claim in the superior court, and we therefore review only for fundamental error.
See State v. Henderson,
II.
A.
¶ 6 The jury found Anderson guilty of three counts of first degree murder. Those verdicts establish beyond a reasonable doubt the existence of the § 13-702(0(1) “serious physical injury” aggravator.
See State v. Martinez,
¶ 7 In addition, the jury concluded beyond a reasonable doubt that each of the murders was motivated by pecuniary gain. See A.R.S. § 13-703(F)(5). 4 Although the jury did not make a separate finding with respect to the motivation for the armed robbery, no reasonable jury could have failed to find the pecuniary gain aggravator, § 13-702(0(6), under the facts of this case. The murders and the armed robbery were committed as part of a continuous course of conduct; the murders were the means by which the armed robbery was accomplished. Thus, under the facts of this case, the failure of the superior court to submit to the jury the issue of motivation for the armed robbery was at worst harmless error. 5
B.
¶8 We held in
Martinez
that nothing in
Apprendi
or its progeny prohibits a trial judge from finding and relying on additional aggravating circumstances once facts sufficient to expose the defendant to a particular range of sentence have been found in conformity with the Sixth Amendment’s jury trial requirement.
III.
¶ 9 Because two aggravating factors and the existence of a historical prior felony conviction were found in accordance with the Sixth Amendment, the aggravated sentence for the armed robbery conviction was constitutionally imposed. We therefore affirm that sentence.
Notes
. The superior court did not identify the statute under which the sentence was imposed. It appears that the trial judge intended to impose the maximum super-aggravated sentence of twelve and one-half years under A.R.S. § 13-702.01(A). That subsection, however, applies only to persons convicted of a felony "without having previously been convicted of any felony.” Because *61 Anderson had a recent prior felony conviction, he was eligible for sentencing under the more punitive provisions of § 13-702.01(C). In order to facilitate appellate review, trial judges should indicate on the record the specific statutory subsection under which a criminal sentence is imposed.
. Anderson acknowledged having been convicted of a felony in 1995, the year before the armed robbery in this case. That conviction qualified as a "historical prior felony conviction" under A.R.S. § 13-702.01(C).
See
A.R.S. § 13-604(V)(2) (Supp.2004) (defining "historical prior felony conviction”). The fact of a prior conviction may constitutionally be found by the trial judge, rather than the jury.
Apprendi,
. The superior court did not identify any aggra-vator with specific reference to § 13-702(C). Rather, the judge simply stated as follows:
The Court finds the following aggravating factors: That the offense was committed by inflicting serious bodily injury, that deadly weapons were used in the commission of the offense, that the offenses were committed with an accomplice, that the goal of the offense was pecuniary gain, that the defendant has a prior felony, and it was committed by ambush. The Court finds all of those aggravating factors to be substantial aggravating factors.
. Following an independent review of the record, this Court also concluded that a pecuniary gain motive was proved beyond a reasonable doubt for each of the murders.
Anderson,
. Given our resolution of this issue, we need not today determine whether a jury verdict of guilty for armed robbery is also a finding that the robbery was motivated by the expectation of the receipt of pecuniary gain.
See
A.R.S. § 13-1902(A) ("A person commits robbery if in the course of taking any property of another from his person or immediate presence and against his will, such person threatens or uses force against any person
with intent either to coerce surrender of property or to prevent resistance to such person taking or retaining property.")
(emphasis added).
