OPINION
¶ 1 Appellant Dean Zinsmeyer appeals his convictions and sentences for theft of a means of transportation and third-degree burglary. He argues the trial court improperly admitted statements he had made during interviews with police because he had invoked his right to counsel and had not knowingly and voluntarily waived his right to remain silent. He additionally asserts the prosecutor improperly vouched for witnesses *617 and the court had considered invalid aggravating factors in sentencing. Zinsmeyer also contends his conviction for third-degree burglary was unsupported by the evidence and, alternatively, the third-degree burglary statute, A.R.S. § 13-1506(A)(1), is unconstitutionally vague. Finally, he argues the court at sentencing improperly entered a criminal restitution order including attorney fees and an indigent assessment fee. We vacate the criminal restitution order and Zinsmeyer’s sentence for theft, but affirm both of his convictions and his sentence for third-degree burglary.
Factual and Procedural Background
¶ 2 On appeal, we view the facts in the light most favorable to sustaining Zinsmeyer’s convictions and sentences.
See State v. Haight-Gyuro,
¶ 3 A grand jury charged Zinsmeyer with theft of a means of transportation, third-degree burglary, and possession of burglary tools. After a two-day trial, the jury found him guilty of theft and burglary but acquitted him of possessing burglary tools. The jury also found Zinsmeyer had a prior felony conviction and had committed these offenses while on probation. The trial court sentenced him to an enhanced, partially aggravated, eight-year prison term for theft and to a concurrent, presumptive, 4.5-year term for burglary. This appeal followed.
Discussion
Motion to Stippress Statements
¶ 4 Zinsmeyer first contends the trial court erred in denying his motion to suppress the statements he had made to investigating detectives. In reviewing the denial of a motion, to suppress evidence, we view the facts in the light most favorable to upholding the trial court’s ruling and consider only the evidence presented at the suppression hearing.
See State v. Ellison,
¶ 5 On September 13, 2005, Zinsmeyer participated in two interviews with detectives from TPD. During his first interview with detectives Ridgeway' and Soltero, Ridgeway advised Zinsmeyer of his rights pursuant to
Miranda v. Arizona,
¶ 6 Later that day, TPD detective Spencer interviewed Zinsmeyer. At the start of the interview, Zinsmeyer told' Spencer that Ridgeway had not informed him of his constitutional rights. Spencer then read Zinsmeyer the Miranda warnings, which Zinsmeyer stated he understood before he began answering Spencer’s questions. Zinsmeyer *618 told Spencer he had found the truck “sitting in [a] trailer park,” the ignition had already been pulled out, he could tell it had been stolen, and he did not know who originally had stolen it. He admitted he had started the truck with a screwdriver he found on the seat and had used the truck for several days, knowing he was “stealing] a stolen ear.”
¶ 7 Before trial, Zinsmeyer moved to suppress his statements to Spencer, arguing that he had invoked his right to counsel during his previous interview with Ridgeway or, in the alternative, that he had not waived his rights knowingly and voluntarily. At the hearing on his motion, Zinsmeyer testified he had “stat[ed] that I think I need a lawyer” during the first interview but had not done so during the second. He also admitted that Spencer had read him the Miranda warnings during the second interview, that he understood his rights, and that he had waived them at that interview. Zinsmeyer testified, however, that he was “high” on the day of the interviews from having used crack cocaine and methamphetamine earlier that day, which he said had impaired his memory and cognition. He also stated that he had smoked crack cocaine the night before the interviews and during the interviews was experiencing withdrawal, which had affected his memory and understanding. After considering the testimony and reviewing the transcripts of Zinsmeyer’s interviews, the court denied Zinsmeyer’s motion, finding he knowingly, intelligently, and voluntarily had waived his rights and had not invoked his right to counsel.
¶ 8 Zinsmeyer asserts the trial court abused its discretion in refusing to suppress statements because he had “invoked his right to' counsel by saying he thought he needed an attorney, and ..., if he did not, ... his waiver was [in]voluntary [and not knowing], in light of the fact that he was withdrawing from having used crack [cocaine] the night before.” A person is entitled to
Miranda
warnings before being subjected to custodial interrogation.
Berkemer v. McCarty,
¶ 9 The state does not dispute the trial court’s implicit finding that Zinsmeyer’s interviews constituted custodial interrogation, and the record supports such a finding.
See Miranda,
¶ 10 “Not every reference to an attorney,” however, “must be construed by police as an invocation of the suspect’s right to counsel.”
Ellison,
¶ 11 Zinsmeyer’s statement that he “th[ought]” he needed an attorney, together with his questions about whether the detec
*619
tives thought he needed one, do not constitute an unambiguous request for counsel.
See, e.g., Davis,
¶ 12 Our inquiry, however, does not end there. Zinsmeyer contends that, even if he did not invoke his right to counsel, any waiver of his rights was neither knowing nor voluntary because he was under the influence of drugs. A waiver is knowing when “made with a full awareness of both the nature of the right being abandoned and the consequences of the decision to abandon it.”
Moran v. Burbine,
¶ 13 The trial court found Zinsmeyer was “an educated [and] intelligent individual” with a General Education Diploma and an “electronics background.” It also found he had “specific prior experience with the justice system!, namely,] he has a prior felony [conviction] and [was] advised of his rights with regard to that incident.” The court concluded that, despite Zinsmeyer’s assertions of impairment, “[t]here was no indication of any kind of impairment ... other than his own [claim during his testimony],” and Zinsmeyer “was [ ]coherent” during both interviews. Last, the court noted the detectives had told Zinsmeyer of his rights during both interviews, he had stated he understood his rights, and he “very, very explieit[ly]” had waived those rights. The record supports these findings. Therefore, we cannot say the court abused its discretion in finding, based on the totality of the circumstances, that Zinsmeyer knowingly had waived his rights.
See Rivera,
¶ 14 Nor was Zinsmeyer’s waiver involuntary. Like the determination whether a statement was knowing and intelligent, “[v]oluntariness is a question of fact to be determined from the totality of the circumstances.”
State v. Davolt,
¶ 15 Zinsmeyer does not contend, and the record does not show, that the detec
*620
tives coerced or improperly induced him to give the statements. Rather, Zinsmeyer suggests the fact he was experiencing drug withdrawal during the interviews rendered his statements involuntary. At one time, Arizona case law “held that if a defendant was so intoxicated that he could not understand the meaning of his statements, then the statements were involuntary.”
State v. Bravo,
Prosecutorial Vouching
¶ 16 Zinsmeyer next argues the prosecutor “improperly vouched for the witnesses” during opening statement and closing arguments. There are two types of improper prosecutorial vouching: when the prosecutor “plac[es] the prestige of the government behind a witness” and when the prosecutor “suggests that additional unrevealed evidence supports a guilty verdict.”
State v. Palmer,
¶ 17 Zinsmeyer first asserts the prosecutor’s remark in her opening statement that, “through good law enforcement investigation, [the police] f[ound] Mr. Zinsmeyer,” constituted improper vouching because it implied police “had found the correct criminal.” But even if it is improper for a prosecutor to characterize the quality of a police investigation, this isolated statement was not so egregious as to result in a denial of due process.
See Van Den Berg,
¶ 18 Second, Zinsmeyer argues the prosecutor’s statement in closing argument, during discussion of the possession of burglary tools charge, that “the state is satisfied the burglary with the motor vehicle and what tool is it?” improperly suggested “the state was satisfied burglary occurred.” Zinsmeyer contends this statement was an assertion the prosecutor was “satisfied with the evidence” and therefore “believed all of the witnesses.” We disagree. Although the statement is difficult to understand, read in context, it is nothing more than an assertion the state had presented sufficient evidence a burglary had occurred, followed by argument that Zinsmeyer had committed the burglary with tools found in the truck. The prosecutor’s statement did not “placet ] the prestige of the
*621
government behind a witness” or “suggest[ ] that additional unrevealed evidence supported] a guilty verdict.”
Palmer,
¶ 19 Last, Zinsmeyer contends the prosecutor improperly characterized the defense closing argument as “attacking what police did instead of looking at what the defendant did,” reasoning the prosecutor’s statement “impli[ed] ... that the police were too trustworthy to warrant attack.” When she made this comment, the prosecutor was responding to purported deficiencies in the police investigation that Zinsmeyer had identified in his closing argument. Zinsmeyer cites no authority, and we find none, suggesting a prosecutor may not respond to a defendant’s argument that law enforcement’s investigation of a crime was inadequate. There was nothing improper in the prosecutor’s argument.
Improper Aggravating Factors
¶ 20 As previously noted, the jury found Zinsmeyer had stolen the truck while on probation and had a prior felony conviction. After trial, the case was consolidated for sentencing with two other cases, one in which Zinsmeyer had pled guilty and another in which he had admitted a probation violation. The trial court sentenced him to an enhanced, partially aggravated, eight-year prison term for the theft conviction in this case, finding as aggravating factors that he was on probation at the time of the offense and— mistakenly — that “the offense involved accomplices and was committed for pecuniary gain.” See AR. S. § 13-1814(D) (theft of means of transportation class three felony); A.R.S. § 13-604(B) (maximum aggravated prison term thirteen years); see generally A.R.S. § 13-702(C) (listing aggravating factors). 2 That the offense was committed while the defendant was on probation is not a specifically listed aggravating factor and, therefore, falls under the “catch-all” provision of former § 13-702(0(24): “Any other factor that the state alleges is relevant to the defendant’s character or background or to the nature or circumstances of the crime.” That provision is identical to the current catch-all provision found in A.R.S. § 13-701(D)(24).
¶ 21 Zinsmeyer asserts the trial court improperly found as aggravating factors that the theft was committed for pecuniary gain and with accomplices. The state concedes those factors were found improperly, noting the court “apparently confused” the facts of this theft with those of another of Zinsmeyer’s offenses for which he 'was being sentenced at the same hearing. The transcript of the sentencing hearing shows that, when discussing Zinsmeyer’s conviction in another matter, the state had argued the sentence for that conviction should be aggravated based on the presence of accomplices and Zinsmeyer’s apparent pecuniary motive. The state made no such allegations regarding the convictions in this matter.
¶ 22 Zinsmeyer argues our supreme court’s recent decision in
State v. Schmidt,
¶ 23 The state argues that
Schmidt
is inapplicable because the trial court also relied on Zinsmeyer’s prior felony conviction to aggravate his sentence. But the state misinterprets the court’s sentencing minute entry and colloquy. The court sentenced Zinsmeyer to an enhanced sentence based on his prior conviction..
See
A.R.S. § 13-604(B). Although its minute entry lists Zinsmeyer’s prior felony conviction as a “[e]ircumstanee[ ]” relevant to his sentence, while pronouncing Zinsmeyer’s sentence, the court did not cite his prior conviction as an aggravating factor. “Where there is a discrepancy between the oral sentence and the written judgment, the oral pronouncement of sentence controls.”
State v. Hanson,
¶ 24 Consequently, without the improper aggravating factors listed by the trial court — pecuniary gain and the presence of accomplices — the only remaining aggravating factor actually found by the court was the fact Zinsmeyer had committed theft while on probation, which, as we noted above, falls within the catch-all provision. Thus, under
Schmidt,
the court could not aggravate Zinsmeyer’s sentence solely on that basis.
See
¶ 25 Because it encompasses only factors alleged by the state that relate to the defendant’s character or background or to the nature of the crime, the current version of the catch-all arguably narrows the “virtually unlimited ... discretion” the language of the former provision afforded a trial court.
Schmidt,
¶ 26 Zinsmeyer admits he did not object to the trial court’s imposition of an aggravated sentence. Thus, he has forfeited the right to relief unless he can show fundamental, prejudicial error occurred.
See Henderson,
Sufficiency of thy Evidence of Third-Degree Burglary
¶ 27 Zinsmeyer claims the state presented insufficient evidence to support his conviction for burglary in the third degree. His sole argument on this claim is that the subsection of the third-degree burglary statute under which he was convicted, A.R.S. § 13-1506(A)(1), does not apply to vehicles “which cannot be inhabited.” Although Zinsmeyer moved for a judgment of acquittal at trial pursuant to Rule 20, Ariz. R.Crim. P., he did not make the argument he now raises on appeal. Therefore, he has forfeited this argument absent prejudicial, fundamental error.
See Henderson,
¶ 28 When interpreting a statute, “[o]ur goal ... is to discern and implement the intent of the legislature.”
Id.
¶ 8,
*624
¶ 29 Section 13-1506(A)(1) provides that a person commits third-degree burglary by “[ejntering or remaining unlawfully in or on a nonresidential structure ... with the intent to commit any theft or any felony therein.” Section 13-1501(12), A.R.S., defines the term “[sjtrueture” as “any vending machine or any building, object, vehicle, railroad car or place with sides and a floor that is separately seeurable from any other structure attached to it and that is used for lodging, business, transportation, recreation or storage.” This court recently confirmed that § 13-1506(A)(1) includes burglary of a motor vehicle.
See Hamblin,
¶ 30 Zinsmeyer attempts to inject ambiguity into the statutes by emphasizing the definition of the phrase “[ejnter or remain unlawfully.” As provided in § 13-1501(2), the phrase is defined as
an act of a person who enters or remains on premises when the person’s intent for so entering or remaining is not licensed, authorized or otherwise privileged except when the entry is to commit theft of merchandise displayed for sale during normal business hours, when the premises are open to the public and when the person does not enter any unauthorized areas of the premises.
(Emphasis added.) Zinsmeyer observes the term “premises” is not defined in the statute and offers a dictionary definition of the term that restricts it to a “house or building, along with its grounds.” See Black’s Law Dictionary 1219 (8th ed.2004). Thus, Zinsmeyer argues, the use of the term “[ejntering or remaining unlawfully” in § 13 — 1506(A)(1) means third-degree burglary under that subsection is only accomplished when a person enters or remains in a house or building or its grounds. Because a truck is not a house, a building, or grounds, Zinsmeyer posits that trucks — and all vehicles that cannot be inhabited — must necessarily fall outside the scope of § 13-1506(A)(1).
¶ 31 Were we to accept Zinsmeyer’s argument, we would have to define “vehicle,” as used in the definition of “[sjtrueture” in § 13-1501(12), as “a vehicle that can be inhabited.” But, had the legislature intended the term “vehicle” to have such a restrictive interpretation, it would have said so expressly.
See Hamblin,
¶ 32 We conclude it would be patently unreasonable to construe the word “premises” in § 13-1501(2) as an unexpressed limitation on the word “vehicle” in § 13-1501(12).
See Hamblin,
¶ 33 Thus, the jury properly could find Zinsmeyer guilty of third-degree burglary if it found he had remained unlawfully in a truck with the intent to commit theft of that truck. § 13 — 1506(A)(1). Substantial evidence, including his own testimony, supports the jury’s finding that he did so. Because Zinsmeyer other-wise does not challenge the sufficiency of the evidence to support this conviction, he has failed to show error, fundamental or otherwise.
See Henderson,
Vagueness Claim
¶34 In the alternative, Zinsmeyer argues the third-degree burglary statute is
*625
unconstitutionally vague. He acknowledges he did not raise this argument below, but this court may consider a vagueness challenge to a statute even when raised for the first time on appeal.
See State v. Anderson,
¶ 35 A statute is “unconstitutionally vague if it does not give persons of ordinary intelligence a reasonable opportunity to learn what it prohibits and does not provide explicit standards for those who will apply it.”
State v. Takacs,
¶ 36 Zinsmeyer argues § 13-1506(A)(1) is unconstitutionally vague because of the purported contradiction between the definition of “[s]trueture” in § 13-1501(12) to include vehicles and his proffered dictionary definition of “premises,” a term used in § 13-1501(2), which excludes vehicles. Zinsmeyer claims that, because of this contradiction, a person of ordinary intelligence would not know whether the third-degree burglary statute applies to vehicles. But, in keeping with our analysis of Zinsmeyei,’s sufficiency-of-the-evidenee claim, we conclude the inclusion of the statutorily undefined term “premises” in § 13-1501(2) cannot reasonably be interpreted to exclude “vehicles” from the express definition of “[structure” in § 13-1501(12). The use of the word “premises” is at worst imprecise, and we will not declare a statute invalid simply because it might have been “written with greater precision.”
Ta-kacs,
Criminal Restitution Order
¶ 37 At sentencing, the trial court entered a criminal restitution order requiring Zinsmeyer to pay $400 in attorney fees and a $25 indigent assessment fee.
See
A.R.S. § 13-805. We agree with the parties that this was improper; such orders may only be entered at the completion of a defendant’s sentence.
See
§ 13-805(A);
State v. Lewandowski,
Disposition
¶ 38 For the reasons stated, we vacate both Zinsmeyer’s sentence for theft and the criminal restitution order. We affirm his convictions for theft and third-degree burglary and his sentence for third-degree burglary-
Notes
. In his reply brief, Zinsmeyer asserts the officers nonetheless were required to seek clarification of his ambiguous comments. Assuming they were required to do so, they plainly did.
. Significant portions of Arizona's criminal sentencing code have been amended and renumbered, effective "from and after December 31, 2008." See 2008 Ariz. Sess. Laws, ch. 301, §§ 1-120. Unless otherwise noted, we refer to the versions of those statutes applicable at the time of Zinsmeyer’s offense. See 2005 Ariz. Sess. Laws, ch. 188, § 1 (§ 13-604); 2005 Ariz. Sess. Laws, ch. 20, § 1; ch. 133, § 1; ch. 166, § 1 (§ 13-702).
. In his opening brief, Zinsmeyer argued that, because the trial court relied on two improper aggravating factors, we must vacate his sentence and remand for resentencing under
State v. Peña,
. A defendant would, of course, have notice that committing an offense while on probation would result in the statutory minimum sentence being the presumptive term. See A.R.S. § 13-604.02(B). But that is not the same as notice that committing an offense while on probation could expose a defendant to a sentence exceeding the presumptive term. Thus, we see no principled reason to treat a defendant's probation or release status as different than any other factor falling under the catch-all provision.
