OPINION
¶ 1 This mandatory appeal arises from Mike Peter Gallardo’s conviction and death sentence for the murder of Rudy Padilla. We have jurisdiction under Article 6, Section 5(3) of the Arizona Constitution and Arizona Revised Statutes (“A.R.S.”) section 13-4031 (2010).
FACTUAL AND PROCEDURAL BACKGROUND
¶2 On December 9, 2005, Rudy Padilla was murdered at his parents’ home in Phoenix. Padilla’s father returned from work and saw that a sliding glass door into the house *564 had been broken. He found his son’s body in the master bedroom. Padilla’s wrists and ankles had been bound, a pillowcase had been tied over his head, and he had been shot once in the back of the head. The bedroom was in disarray; jewelry and a revolver were missing. Telephone records showed that Gallardo had called the Padilla home from his cell phone the day of the murder, and DNA profiles developed from evidence at the crime scene matched Gallar-do’s profile. Neither Rudy nor his parents knew Gallardo.
¶ 3 Gallardo was indicted for first degree murder, burglary, and kidnapping. After a mistrial for juror misconduct, a second jury was impaneled. This jury convicted Gallardo on all counts. In the aggravation phase, the jury found two aggravating factors: Gallardo had been previously convicted of a serious offense, see A.R.S. § 13-751(F)(2) (2010), and the murder was especially cruel, id. § 13-751(F)(6). (Statutes are cited in their current version unless they have materially changed since the date of the offense.) In the penalty phase, the jury determined Gal-lardo should receive a death sentence for the murder. The trial court also sentenced Gal-lardo to concurrent prison terms of 15.75 years for the burglary and kidnapping counts.
DISCUSSION
¶4 Gallardo raises six issues on appeal. For the reasons explained below, we affirm his convictions and sentences.
A. Mistrial After Juror Misconduct
¶ 5 Gallardo argues that the trial court erred in declaring a mistrial after several jurors prematurely discussed the evidence.
¶ 6 The decision to grant a mistrial rests within the sound discretion of the trial court.
McLaughlin v. Fahringer,
¶ 7 At the beginning oí the guilt phase, the trial court admonished the jurors not to discuss the ease “until all the evidence has been presented and [you] have retired to deliberate on the verdict. You therefore may not discuss the evidence amongst yourselves until you retire to deliberate on your verdict.”
¶8 Upon learning that some jurors had prematurely discussed the evidence, the trial court individually questioned each of the sixteen impaneled jurors. The parties agreed that one juror (Juror 13) should be excused for an unrelated hardship. The tidal court found that three other jurors should be excused for violating the admonition and not candidly responding to questions. The trial court also found that three other jurors had formed opinions about other jurors that would affect their deliberations. Striking all these jurors would not leave twelve to deliberate; striking only those who violated the admonition would leave no alternates for a capital case expected to last three months. The trial court also found it “highly likely” that four other jurors had violated the admonition despite having denied doing so.
¶ 9 Gallardo argues that less onerous sanctions were available, all of the jurors stated they could remain fair and impartial, and he was satisfied with the jurors selected. But he agreed to the removal of two jurors (Jurors 11 and 13), and he offers no good reason to question the trial court’s conclusions about the others. The trial court carefully considered Gallardo’s interest in having the trial concluded by the originally impaneled jury *565 and did not abuse its discretion in declaring a mistrial.
B. Batson Challenge
¶ 10 Gallardo argues that the trial court erred in denying his challenges to the State’s peremptory strikes of three minority jurors during selection of the second jury. We review for clear error.
State v. Roque,
¶ 11 Excluding a potential juror based on race violates the Equal Protection Clause of the Fourteenth Amendment.
Batson v. Kentucky,
¶ 12 The trial court did not clearly err in overruling Gallardo’s
Batson
challenges. Although Gallardo made a prima facie showing of discrimination, the State offered an explanation for each strike “based on something other than the race of the juror.”
Hernandez v. New York,
¶ 13 The trial court found that the reasons the State articulated were not pretexts and there was no pattern or practice of discrimination. Other minority jurors were ultimately selected for the panel, and “[although not dispositive, the fact that the state accepted other [minority] jurors on the venire is indicative of a nondiscriminatory motive.”
Roque,
C. (F)(6) Aggravator
¶ 14 Gallardo argues that the State failed to present sufficient evidence to support the jury’s finding that the murder was “especially cruel.” He also argues that the jury instruction on the (F)(6) aggravator was unconstitutionally vague and improperly reduced the State’s burden of proof.
1. Sufficiency of the Evidence
¶ 15 We determine whether substantial evidence supports the jury’s finding, viewing the facts in the light most favorable to sustaining the jury verdict.
Id.
at 218 ¶ 93,
¶ 16 Under AR.S. § 13-751(F)(6), a first degree murder is aggravated when “[t]he defendant committed the offense in an especially heinous, cruel or depraved manner.” “A finding of cruelty alone is sufficient to establish the [ (F)(6) ] aggravator.”
State v. Morris,
¶ 17 The record contains substantial evidence that Rudy experienced mental anguish before death and that Gallardo knew or should have known that such suffering would occur. Rudy almost certainly was conscious when bound, as there is no reason to bind an
*566
unconscious person.
See State v. Lynch,
¶ 18 Moreover, there is evidence that Rudy straggled against the ligatures attempting to free himself.
See Lynch,
¶ 19 That Rudy was bound hand and foot, a pillowcase was tied over his head, and he struggled to free himself also indicates he had time to suffer significant uncertainty as to his fate.
See Lynch,
¶ 20 The evidence supports the jury’s finding that the murder was especially cruel.
2. F(6) Jury Instruction
¶ 21 Arizona’s (F)(6) aggravator is facially vague but may be remedied by appropriate limiting instructions.
See Walton v. Arizona,
¶ 22 The trial court here gave the following (F)(6) instruction:
Concerning this aggravating circumstance, all first-degree murders are to some extent cruel. However, this aggravating circumstance cannot be found to exist unless the State has proved beyond a reasonable doubt that the murder was “especially” cruel. “Especially” means “unusually great or significant.”
The term “cruel” focuses on the victim’s pain and suffering. To find that the murder was committed in an “especially cruel” manner you must find that the victim consciously suffered physical or mental pain, distress or anguish prior to death. Mr. Gallardo must know or should have known that the victim would suffer.
¶ 23 The instruction contains the two “essential narrowing factors” identified in
Tucker
and is materially identical to instructions we have previously upheld.
See, e.g., State v. Chappell,
D. Victim Impact Evidence
¶24 Gallardo argues that victim impact statements by Rudy’s parents were unduly prejudicial and denied him due process. He contends that he limited his mitigation evidence to avoid infusing “irrelevant emotions into the proceeding” and the parents’ statements caused the jury to sentence him to death based on “raw emotion.” He also argues that the victim impact evidence was irrelevant to the mitigation presented and that, absent a curative instruction, the jury was improperly allowed to make “comparative judgments on the value of human life.”
*567
¶ 25 Arizona law generally allows victim impact evidence during the penalty phase to rebut mitigation.
See
Ariz. Const, art. II, § 2.1(A)(4) (entitling a victim to be heard at sentencing); A.R.S § 13-752(R) (allowing victim to present information during penalty phase about the murdered person and the impact of the murder on the victim and other family members). “Victim impact evidence should not be allowed, however, if it is ‘so unduly prejudicial that it renders the trial fundamentally unfair.’ ”
State v. Dann,
¶ 26 Gallardo did not object to the victim impact evidence until after it was presented, when he moved for a mistrial. The trial court’s decision whether to grant a mistrial is reviewed for an abuse of discretion,
Dann,
¶ 27 In their statements, Rudy’s parents spoke of Rudy’s character and the impact of his murder upon their family. Mr. Padilla ended his statement by playing the 911 call he made after finding his son murdered. The Padillas’ statements did not call for any specific sentence and were within the appropriate bounds of victim impact testimony — discussing only the kind of person Rudy was and how his death affected his family.
¶28 Gallardo argues that the statements were irrelevant to the “limited and truncated” mitigation presented. Admissibility of victim impact statements does not depend on the particular mitigation evidence presented by the defendant. Jurors may “consider mitigating circumstances, whether proved by the defendant or present in the record, in determining whether death is the appropriate sentence.”
State ex rel. Thomas v. Granville (Baldwin),
¶ 29 Although the jurors were moved by the statements, and some passed a tissue box, the statements were not “so unduly prejudicial” as to render the trial fundamentally unfair.
See State v. Glassel,
¶30 Gallardo also argues that the trial court failed to instruct jurors (1) not to rely on the statements for “a purely emotional response,” and (2) “not to make comparative judgments about the value of human lives.” “We review de novo whether jury instructions adequately state the law.”
Tucker,
¶ 31 The cases Gallardo cites do not suggest the trial court’s instructions were inadequate.
State v. Bocharski
states that the “trial judge appropriately instructed the jurors that they could consider the victim impact statement only to rebut the mitigation evidence.”
¶ 32 Although this Court has approved jury instructions containing the language suggested by Gallardo, we have never held that such language is required.
See Dann,
E. Prosecutorial Misconduct
¶ 33 Gallardo argues that comments made by the State during its penalty phase opening statement and closing argument constituted prosecutorial misconduct and deprived him of a fair trial and due process.
¶
34
We “will reverse a conviction for prosecutorial misconduct if (1) misconduct is indeed present; and (2) a reasonable likelihood exists that the misconduct could have affected the jury’s verdict, thereby denying [the] defendant a fair trial.” State
v. Velazquez,
¶ 35 We separately “evaluate each instance of alleged misconduct, and the standard of review depends upon whether [the defendant] objected.”
Morris,
1. Reference to Gallardo’s Prison Packet
¶ 36 Before the penalty phase, Gallardo filed a motion to limit the scope of rebuttal evidence. Gallardo stated that he intended to present only two categories of mitigation: expert testimony regarding the conditions of confinement in the maximum security units of Arizona prisons and testimony by members of his family about their affection for him and the impact a death sentence would have on them. Gallardo asked the court to preclude the State from asking witnesses about his “criminal history, institutional history, or any other past events,” and in particular an incident involving a handcuff key, escape attempts, or the expert’s conversations with Gallardo. The trial court granted the motion.
¶ 37 Gallardo contends that the prosecutor committed misconduct by suggesting in his opening statement that Gallardo’s prison packet would illustrate his personal history. Gallardo, however, miseharacterizes the prosecutor’s remarks. The prosecutor simply stated that Gallardo’s expert had not reviewed the Arizona Department of Corrections’ records for Gallardo, which had been previously admitted, but instead would talk about the treatment of inmates generally. By noting the limited scope of the expert’s opinion, the prosecutor did not violate the trial court’s ruling on the scope of rebuttal.
2. Reference to Gallardo’s Childhood and Intelligence
¶ 38 In his opening statement, the prosecutor stated that the jury would hear evidence regarding Gallardo’s childhood. Gallardo objected and moved for a mistrial, arguing the statement violated the court’s ruling on the scope of rebuttal. The trial court denied a mistrial but ruled that the prosecutor could not introduce evidence of Gallardo’s childhood or intelligence unless the defense “opened the door” on those issues.
¶ 39 The prosecutor’s statements about the anticipated evidence concerning Gallardo’s childhood and intelligence did not violate the court’s prior ruling on the motion in limine or otherwise constitute misconduct, given that the judge’s ruling precluding such evidence came only after the opening statement. Moreover, Gallardo later offered testimony by his sister about his family and argued in *569 closing that his family members had been in the courtroom and the jury should consider that “[t]hey care about him.” The defense did not offer evidence regarding Gallardo’s intelligence, and the prosecutor did not comment on this issue again after the court’s ruling.
¶ 40 Even if the comments by the prosecutor were improper, we would reverse only if Gallardo established “a ‘reasonable likelihood’ that the ‘misconduct could have affected the jury’s verdict.’ ”
Newell,
3. Comparison of Victim and Gallardo
¶41 In closing argument, Gallardo argued that a life sentence was “sufficient punishment” given the “severe restriction” and “isolation]” of prison. In response, the prosecutor said that maximum security inmates are allowed to watch television, receive magazines, make phone calls, and see visitors. Noting that victim impact statements could rebut mitigation, the prosecutor then said, “Do you think [Rudy’s father is] going to be able to call his son, Rudy____” The defense objected to the comparison between Gallardo and the victim, and the trial court sustained the objection.
¶ 42 Even if the prosecutor’s statements were improper, reversal is not required.
See Newell,
4. Reference to Mitigation Witness’s Fees
¶ 43 In the penalty phase, Gallardo presented expert testimony from a retired corrections director about the conditions of maximum security facilities in Arizona. During cross examination, the prosecutor elicited testimony concerning the expert’s fees and potential bias. During closing argument, the prosecutor characterized this testimony as an inconsistent statement, Gallardo objected to the argument as misleading, and the trial court sustained the objection. The prosecutor persisted with the line of argument and the trial court twice sustained further objections.
¶ 44 A prosecutor should not repeat an argument after it has been the subject of a sustained objection.
Cf. Pool v. Superior Court in and for Pima County,
5. Misstatement of the Law
¶ 45 Gallardo further claims that it was improper for the prosecutor to suggest in closing that the jurors must vote for death
*570
if they found no mitigation. We have previously rejected this argument: “Under our sentencing scheme ... given the findings of one or more aggravators, a juror must vote to impose a sentence of death if he or she determines there is no mitigation at all or none sufficiently substantial to warrant a sentence of less than death.”
Tucker,
6. Cumulative Effect
¶ 46 Gallardo argues that even if no single incident of misconduct warrants reversal, the deliberate and persistent conduct of the prosecutor deprived him of a fair trial. We consider whether “persistent and pervasive” misconduct occurred and whether the “cumulative effect of the incidents shows that the prosecutor intentionally engaged in improper conduct and did so with indifference, if not a specific intent, to prejudice the defendant.”
Morris,
¶ 47 The record does not suggest pervasive prosecutorial misconduct that deprived Gal-lardo of a fair trial.
F. Constitutionality of Burden of Proof at Sentencing
¶ 48 Gallardo argues that Arizona’s death penalty scheme violates the Eighth and Fourteenth Amendments because it does not require the State to prove beyond a reasonable doubt that mitigating circumstances, once proved by the defendant, are not sufficiently substantial to call for leniency. We rejected this argument in
State v. Moore,
G. Review of the Death Sentence
¶ 49 Because the murder occurred after August 1, 2002, we “determine whether the trier of fact abused its discretion in finding aggravating circumstances and imposing a sentence of death.” AR.S. § 13-756(A). We conduct this review even if, as here, the defendant does not argue that the jury’s verdict was an abuse of discretion.
Morris,
1. Aggravating Circumstances
¶ 50 The jury found two aggravating circumstances: Gallardo had been previously convicted of a prior serious offense, see A.R.S. § 13 — 751(F)(2), and the murder was especially cruel, see id. § 13-751(F)(6). As discussed, there is sufficient evidence to support the jury’s finding that Gallardo committed the murder in an especially cruel manner. The jury also properly found that Gallardo had previously been convicted of a serious offense based on evidence of his pri- or convictions for armed robbery and burglary.
2. Death as the Appropriate Sentence
¶ 51 Once the jury finds one or more aggravating factors, each juror must individually determine whether'death is the appropriate penalty.
See
A.R.S. § 13-751(C) (stating that “[e]ach juror may consider any mitigating circumstance found by that juror in determining the appropriate penalty”);
see also Baldwin,
¶ 52 Gallardo presented evidence about the impact of execution on his family and the general conditions of confinement in Arizona’s maximum security facilities. A reasonable juror could conclude that the mitigation presented was not sufficiently substantial to call for leniency.
See State v. Harrod,
H. Issues Preserved for Federal Review
¶ 53 To avoid preclusion, Gallardo raises twelve additional constitutional claims that he *571 states have been rejected in previous decisions by the United States Supreme Court or this Court. The attached appendix lists the elaims raised by Gallardo and the decisions he identifies as rejecting them.
CONCLUSION
¶ 54 We affirm Gallardo’s convictions and sentences.
Appendix
Gallardo raises twelve issues to preserve them for federal appeal. This Appendix lists his claims and the decisions he identifies as rejecting them.
(1) Arizona’s statutory scheme for considering mitigating evidence is unconstitutional under the Eighth and Fourteenth Amendments because it limits consideration of mitigating evidence to that proven by a preponderance of the evidence.
State v. McGill,
(2) Gallardo’s death sentence is in violation of his rights under the Fifth, Sixth, Eighth, and Fourteenth Amendments and the Arizona Constitution because the State failed to allege the aggravating factors that made the defendant death eligible in the grand jury indictment.
McKaney v. Foreman ex rel. County of Maricopa,
(3) Application of the new death penalty law to Gallardo constitutes an impermissible
ex post facto
application of the law.
State v. Ring,
(4) Gallardo’s rights under the Fifth, Sixth, Eighth, and Fourteenth Amendments and under the Arizona Constitution were violated by the admission of victim impact evidence at the penalty phase of the trial.
Lynn v. Reinstein,
(5) The trial court improperly omitted penalty phase instructions that the jury could consider mercy or sympathy in evaluating the mitigation evidence and in determining whether to sentence the defendant to death.
State v. Carreon,
(6) The death penalty is cruel and unusual punishment.
State v. Harrod,
(7) The death penalty is arbitrarily imposed in violation of Gallardo’s due process rights under the Fourteenth Amendment and under the Arizona Constitution.
State v. Beaty,
(8) The prosecutor’s discretion to seek the death penalty unconstitutionally lacks standards.
State v. Sansing,
(9) The death penalty in Arizona has been applied in a manner that discriminates against poor, young, and male defendants in violation of the Arizona Constitution.
Sansing,
(10) The absence of proportionality review by Arizona courts of a defendant’s death sentence is unconstitutional under the Fifth, Eighth, and Fourteenth Amendments and Article 2, Section 15 of the Arizona Constitution.
Harrod,
(11) Arizona’s death penalty statute unconstitutionally presumes that death is the appropriate sentence.
State v. Miles,
(12) Execution by lethal injection is cruel and unusual punishment.
State v. Van Adams,
